0. SUMMARY

0.1. OBJECTIVES AND SCOPE OF THE REGIONAL MASTER PLAN

This section relates to Chapter 1 of the main Report.

The Government of Bulgaria has received a loan from the World Bank to implement a

Municipal Infrastructure Development Project. Its strategic aims are to (a) improve the

reliability and quality of water provision to the communities in selected settlements in

the project area and (b) assist municipalities to improve investment-planning capacity.

The SEURECA, SCE, Arcadia Engineering and Hidroproekt-Sofia Joint-Venture has

been engaged through the Ministry of Regional Development and Public Works

(MRDPW) to provide consultancy services for the Preparation of the Regional Water

Supply and Sewerage Master Plans in the Central Region of Bulgaria.

The objective of the project is to improve the water supply and sewerage systems on

the considered region in compliance with the European Directives and the National

Environmental Strategy of Bulgaria, which main objective is to “provide good quality

and sufficient quantity of water for different purposes”. This will be done by defining

the necessary assets, asset improvements and non-investment measures allowing

meeting the needs of the population and the financial plan to be applied for such an

achievement. The Master Plan implementation period is 2014-2038.

The regional master plan will serve to support the policy of development of the water

supply and sewerage infrastructure and the corresponding financial plan. It will serve

as a basis for the subsequent stages of development: feasibility studies, application

forms, tender documentation, design and construction.

The present report is exposing the outcomes of the Study conducted on the territory of

the ViK OOD – Kardzhali within the framework of the Regional Water Supply and

Sewerage Master Plans in the Central Region of Bulgaria.

0.2. CURRENT SITUATION AND DEFICIENCIES

This section relates to Chapters 2 and 3 of the main Report.

GENERAL CHARACTERISTICS 0.2.1.

Project area 0.2.1.1.

The area serviced by ViK OOD – Kardzhali includes the municipalities of Ardino,

Dzhebel, Kirkovo, Krumovgrad, Kardzhali, Momchilgrad, Chernoochene. All of them

are locates on the territory of Kardzhali District.



The general situation on the territory of Water Supply and Sewerage OOD – Kardzhali

is presented in drawing №1 and drawing № 26.

Natural features 0.2.1.2.

Geographical features

Kardzhali District has a territory that covers 3 209,1 sq. km. The region is located in

Southern Bulgaria at the border with the Republic of Greece. The landscape is mainly

mountainous and semi-mountainous. The main rivers crossing the territory are: Arda

River (passing through the town of Kardzhali), Varbitsa River (passing near the town

of Momchilgrad and the village of Benkovski, Municipality of Kirkovo), Ardinska River

(passing through the town of Ardino), Krumovitsa River (passing near the town of

Krumovgrad).

The climate is Transitional continental to Transitional Mediterranean type with average

annual precipitation of about 687 mm and snow coverage with duration of about 4

months.

Hydro-geological conditions

The hydro-geological conditions within the area of Kardzhali District are determined by

karst, crack and pore groundwater.

Karst water is contained mainly in the marble bodies, where they form groundwater

body “Karst water – Ardino-Nedelinski basin” under code BG3G00000Pt042. Its

chemical content is mainly hydro-calcium with mineralization in the range of 200-500

mg/l.

Fissure water is formed in Paleogene and Pre-Cambrian rocks, where three

groundwater bodies are formed. They are pressureless bodies characterized by

shallow circulation of groundwater in the hypergenic, cracked and weathered zone.

The chemical content of fissure water is: hydrocarbonate-sulphate-calcium-

magnesium with mineralization of 100-600 mg/l.

Kardzhali

Figure 0-1 Location of ViK OOD – Kardzhali



Pore water is accumulated in the gravel-sand Paleogene and Neogene sediments and

Quaternary, alluvial and delluvial formations. The following groundwater body is

formed in them: “Pore water in Quaternary – Arda River” under code

BG3G000000Q010. Pore water is mainly hydrocarbonate-calcium-sodium with

average mineralization of 500-600 mg/l. Its chemical status is “good”.

Groundwater is fed by precipitation and surface water. It is drained in the river-ravine

network and through water abstraction facilities.

Groundwater quality meets the requirements of Ordinance №9/2001 on the quality of

water intended for drinking purposes.

Besides the described groundwater bodies, on the territory of Kardzhali District are

also situated mineral water deposits “Dzhebel” and “Kirkovo”, which are exclusive

state property.

Geological conditions and soils

The territory of Kardzhali District, serviced by “Water Supply and Sewerage” OOD –

Kardzhali, structurally falls within the Eastern Rhodopes part of the Rhodopes massif.

Its geological structure includes metamorphic rocks (gneisses, schists, leptynites,

amphibolites, marbles and calc-schists, etc.), sediments and volcanogenic rocks

(sandstones, marls, limestones, shales, andesites, lavas, tuffs, mixture of tuffs and

tuffites) and Quaternary formations include alluvial sediments along Arda River and its

tributaries Varbitsa, Krumovitsa, Perperek, etc. (gravels, sands, clays) and delluvial

formations of sandy clays with rock parts on some places, covering the root rocks with

sporadic distribution.

The predominant soil type in the District of Kardzhali is maroon soils. There are also

brown forest soils, humus-calcareous, alluvial, delluvial, cinnamon - podzolic and other

soil types.

Environmental and Ecological features

The ecological and environmental features can be summarized as follows:

• All groundwater bodies on the territory of ViK OOD – Kardzhali are in the list

of the “Sensitive Zones” in Bulgaria. Pollution assessment is presented in

Appendix 3-5.

• The groundwater bodies on the territory of ViK OOD – Kardzhali from which

water for human consumption is abstracted are in good condition.

• Water Supply and Sewerage OOD – Kardzhali has sufficient quantity of

resources and groundwater sources to meet the drinking-domestic and other

needs of the population in the services settlements. There are no restrictions

for the usage of surface and groundwater for domestic-drinking water supplies

and other needs, since water quality meets the requirements of the respective

legal and normative documents.

• The anthropogenic pollution of separate water bodies from point and diffuse

pollutants does not affect drinking water quality.



• In the last years there is an establishing tendency for reduction of soil and

groundwater pollution with nitrates as a result of applying programs for

ecological agriculture and stock breeding and the introduced control over the

activity of agricultural producers and stock breeding farms.

• The impact of the activity from OTsK – Kardzhali AD (with declining functions)

over water, soil and air in the last years is strictly controlled by RIEW Haskovo

so that it meets the ecological standards.

• The proposed investment measures in the Regional Master Plan of the

designated territory will contribute for improving the status of the water bodies

and for sustainable development of the ecosystems as a result of collecting

and transporting wastewater for treatment in modern WWTP.

• Thus are prevented potential threats and risks to the environment and health

risk for the population in the area.

• The municipalities in the designated territory have available an approved by

the competent authorities waste management programs. For the sludge of the

urban WWTP of the settlements included in the investment program there are

elaborated sludge management programs and it is necessary to update them

regularly by specifying the possibilities for their utilization.

• The municipalities in Kardzhali District suspended in advance the operation of

the old municipal landfills, closed down under program “Regional Centre for

Waste Management – Kardzhali” (RCWM).

• The designated territory is characterized with rich biological diversity, which is

confirmed by the high level of saturation with protected areas and zones,

controlled by RIEW – Haskovo. More data are presented in item 3.1.4.3.

Socio-economic features 0.2.1.3.

Total number of population on the territory of ViK OOD – Kardzhali is 152 808

inhabitants, divided in 471 settlements. The region services by ViK OOD – Kardzhali

includes 244 settlements (135,274 people), and the remaining 227 are self-serviced

(there is no private operator on the territory of ViK OOD – Kardzhali). The relative

share of the serviced population in the designated territory amounts to 88,5% of the

entire population of Kardzhali District. Out of the 244 settlements serviced by ViK

OOD – Kardzhali one settlement has population of more than 10,000 inhabitants

(Kardzhali) and 5 are between 2,000 and 10,000 inhabitants (the town of Ardino, the

town of Dzhebel, the village of Benkovski, the town of Krumovgrad and the town of

Momchilgrad).

The repartition of the population among the municipalities is presented below. In the

municipality of Chernoochene there is no settlement with population of more than

2,000 inhabitants. In the municipality of Kirkovo there is one settlement with population

of more than 2,000 inhabitants, and that is the village of Benkovski.

Regional GDP data is collected at NUTS II level and at NUTS III level it is limited and

presented for 2 years behind. The designated territory of ViK OOD Kardzhali falls

within the boundaries of South Central Region, which produces approximately 14% of

the national GDP and has lower economic growth as compared to national

tendencies. These differences are significant and growing with time (GDP per capita in

2010 is about 70% of the average national compared to over 76% in 2000 and it may

be assumed that while the regional economic growth follows the national trends, the

difference will increase at a lower rate. Statistical data for the GDP in Kardzhali

Districts indicates economic growth lower not only than the national but also than the

regional one. In 2010 GDP per capita in Kardzhali District amounts to only 54,2% of

the national average and 77% of the regional GDP per capita. At the same time as per

data of the Territorial Statistics Bureau – Kardzhali in 2011 the general income per

capita is 86,27% of the average income of the households in the country.

The slower economic development in the region and the higher unemployment level

additionally contribute to population reduction and especially for the higher out-

migration. Economy development in the designated territory as a whole follows the

growth rate of the national one but is below the average for each of the most important

economic and social parameters – demographic growth, net sales revenue growth,

household income and unemployment. Employment in the district is one of the lowest

in the country, and as a result of the crises it shrunk to below 40% employed (among

people aged 15 and more). In Kardzhali Municipality are employed about two thirds of

all employed and hired people in the district. Over 97% of the active enterprises in the

designated area are micro, small and medium enterprises. The district is rich in

mineral resources and has traditions in the processing and mining industry. The

deposits of mineral resources turn the district into a raw basis for the development of



ferrous metallurgy, logging, processing of non-metalliferous minerals. Textile, clothing

and food industries and machine building are also developed. There are good

traditions for growing oriental tobacco in the district.

Water and Wastewater services 0.2.1.4.

ViK OOD – Kardzhali is a legal entity, which is 51% state ownership and the

remaining 49% are owned by the municipalities. The total capital of the company

amounts to EUR 161,600.2 (BGN 316,090). For the year of 2011 the turnover

amounted to EUR 3,658,040 (BGN 7,154,396) and net income to the amount of EUR

3,424,630 (BGN 6,698,000).

The total number of WSSC employees is 345, 294 of which work in water supply, 11

work in sewerage and 40 are in the administrative department.

The price approved by SEWRC as of 28.02.2013 in the designated territory of Water

Supply and Sewerage OOD – Kardzhali for water supply and discharge is 0.613

EUR/m3 by pumping, and 0.42427 EUR/m3 by gravity, while the price for domestic

and industrial wastewater collection amounts to 0.046 EUR/m3. The average price is

056 EUR/m3, which is close to the price formed at a threshold of 4% of the average

income of the deciles groups with the lowest income.

CURRENT SITUATION OF WATER SUPPLY AND SEWERAGE 0.2.2.

SYSTEMS

The synthesis of the current situation and the compliance with EU directives regarding

water supply and sewerage, settlement by settlement, is presented in chapter 0.10.

100% of the settlements have access to drinking water.

Water sources 0.2.2.1.

0.2.2.1.1. General status

ViK OOD – Kardzhali uses 72 different water sources, distributed as follows:

• Captured springs – 26;

• Dams for water supply purposes – 1 – Borovitsa Dam;

• Mountain water intake – 1 – Kozma Dere River;

• Shaft wells – 30;

• Tube wells – 6;

• Drainages – 8;

Arda River is the main surface water source for the territory of ViK OOD – Kardzhali.

Water gathers in Borovitsa Dam and after treatment at Enchets DWTP it is used for

the water supply of the town of Kardzhali and the northern part of the town of

Momchilgrad.



Groundwater is karst, fissure and pore in alluvial river terraces. It is used for the water

supply of the remaining settlements. The quality of the groundwater is compliant with

Ordinance №9/16.03.2001, which transposes the EU Directive on the quality of water,

intended for drinking water purposes (98/83/ЕС). The sanitary protection zones are

established in compliance with Ordinance №3/16.10.2000 and are currently in good

condition. Water meters are not installed at each water abstraction facility.

At present the available capacity of the groundwater sources is sufficient to meet the

domestic-drinking and other needs of all serviced settlements. There have been no

interruptions in water supply for the last 5 years.

All water sources, which are in exploitation have or used to have water abstraction

permits. Some of the permits should be renovated.

Water pollution 0.2.2.2.

The quality of water for drinking-domestic water supply is monitored pursuant to

Ordinance No9/16.03.2001 by Basin Directorate for Water Management in East

Aegean Sea Region in the town of Plovdiv and by the Regional Health Inspectorate in

the town of Kardzhali. As per the monitoring (See Appendix 2-4 and Appendix 3-4)

carried out the water supplied to the consumers has good quality and is entirely

suitable for drinking purposes. There are no registered infections or diseases caused

by drinking water.

The main problems related to water pollution are:



• Diffuse pollution from settlements with no sewerage networks and no

treatment facilities;

• Point pollution from some sources, such as untreated domestic wastewater

from the settlements, which have sewerage network but no treatment

facilities. At present on the territory of Kardzhali District there are no

constructed wastewater treatment plants. From the town of Kardzhali and

from the town of Momchilgrad untreated wastewater is also discharged in

Arda River and Varbitsa River respectively, however there are ongoing

projects for the construction of WWTP, which should be finalized by July

2015.

• Some industrial companies are also point sources of water pollution as they

discharge untreated or insufficiently treated wastewater directly in the

receiving body. The main potential polluter is OTsK AD Kardzhali, but its

operational activity is in decline in the last few years.

For more details see Section 3.2.

Current water consumption 0.2.2.3.

the territory of ViK OOD – Kardzhali supplying with water a total of 244 settlements,

238 of which with population less than 2000 inhabitants. Due to the landscape

features (mainly mountainous) prevailing are the pumping water supply systems. The

length of the systems supplying the settlements, including their internal distribution

network, is about 513 km, for which we can summarize that 85-90% are made of

highly obsolete asbestos cement and steel pipes.

0.2.2.4.8. Summary of the main deficiencies

Deficiencies concerning the external water supply systems are as follows:

• The pipeline from Borovitsa Dam to DWTP Enchets is old and with leakages,

with high risk of destruction. Besides it is hard to access and in case of failure

water shortage is possible. Water supply security is low;

• Final disinfection at DWTP Enchets is not good;

• Health and safety rules at DWTP Enchets are not maintained;



• 5 of the water sources need renewal of the water abstraction permits;

• Water storage capacity for the town of Kardzhali is not sufficient;

• The pipelines from DWTP Enchets to pressure reservoir 13 000 m3 and to

pressure reservoir 2500 m3 are in poor exploitation status;

• The diameters of some parts of the network are not met according to

Ordinance № 2 on the design and construction of water supply systems.

• It is necessary to install new or to replace the existing water meters

(consumption meters) at the exit of each water source.

The transmission mains made of steel and asbestos cement pipes have a big

percentage of failures, should be reconstructed and duly replaced with new modern

materials. The main deficiencies of the water distribution mains are the following:

• More than 80% of the water supply pipes (main and secondary branches and

service connections) in the settlements with more than 2 000 inhabitants are

made of asbestos cement and steel, with galvanized pipes for the service

connections. Technical losses in distribution networks are significant and at

some places they reach 60% of the total water quantity at the entrance of the

distribution network;

• Network facilities are in the same critical condition. Stop valves and fire

hydrants are insufficient in number, and the existing ones are obsolete and in

bad exploitation condition.

Measuring devices are in unsatisfactory condition and there are none at places.

Calibration of water meters should be carried out regularly (every 5 years). A

significant percentage of the installed water meters are more than 10 years old. For

more detailed information on the main deficiencies of the system see Section 3.4.

Current wastewater systems 0.2.2.5.

The six main agglomerations (Kardzhali, Momchilgrad, Krumovgrad, Ardino, Dzhebel,

and Benkovski) have a constructed wastewater system. Two of them will be

connected to a WWTP after the ongoing projects are finalized (Kardzhali – date of

completion: July 2015; Momchilgrad – date of completion: June 2015), while the other

four are not connected to a WWTP.

Sludge from the future WWTP on the territory of ViK OOD – Kardzhali will be disposed

at the regional landfill situated near the town of Kardzhali.

The existing wastewater systems are described and the ongoing projects are also

taken into account. For more detailed information (diameters, exploitation, etc.) see

Section 3.5.

Based on the available information presented by the WSS Operator and the

Municipalities a conclusion can be drawn for the existing sewerage for the remaining

settlements, and more details can be found in Section 3.5.7.

In the smaller settlements with existing wastewater system, the sewerage system is

separate. There is a constructed domestic sewerage system and wastewater is

discharged without treatment in rivers and creeks. Connection rate to the sewerage

system is between 7% to 100%, and the total number of connected population

amounts to about 6530 inhabitants. There are no wastewater pumping stations and

operational wastewater treatment plants.


The main deficiencies of the wastewater systems are as follows:

• currently all settlements with population more than 2 000 P.E. have

wastewater network. However, it is not fully constructed in any of the

agglomerations – the connection rate varies between 45% and 97%. After

implementing the ongoing projects in the towns of Kardzhali and Momchilgrad,

98% and 100% connection rate, respectively will be achieved.

• In the region of ViK OOD – Kardzhali there are no constructed WWTP.

Domestic and non-domestic wastewater is discharged without treatment and

pollutes soil and groundwater. There is a significant risk for the health of the

population. After realizing the ongoing projects the agglomerations of

Kardzhali and Momchilgrad will have modern WWTP.

• A significant part of the current sewerage network is in poor condition – mainly

due to expired exploitation life, insufficient hydraulic conductivity, small or

reverse slopes, construction of bad quality, compromised and blocked areas.

Infiltration reaches 60%-65% in some zones.

• In some agglomerations between 48% - 100% of the combined sewerage

network is with a small diameter – from 150 to 300 mm, i.e. insufficient

capacity to take storm water, which causes risk of flooding.

On-going and pending projects 0.2.2.6.

Several equipment or infrastructure improvement projects have been conducted lately

by different organizations out of the framework of the present Master Plan. Once

identified, these projects are considered in different ways:

• Completed projects to date are included in the existing situation.

• On-going projects (projects that were approved and financed but not

completed to date) are also included in the existing situation. In fact,

corresponding assets are considered as existing, investment costs are not



included within the Master Plan but future operation and maintenance costs

are included for the macro-affordability assessment.

• Projects not approved to date, but the purpose of which are in line with the

Master Plan objectives, are included in the Master Plan. Corresponding

design, investment costs and timeframes are newly assessed according to the

Consultant’s methodology (Section 4.1.).

• Other projects, which are not in line with the objectives and criteria of the

Master Plan, are either not included or substantially altered.

For the Master Plan of the designated territory of Water Supply and Sewerage OOD –

Kardzhali all non-completed projects were either considered as on-going (and thus

their costs were not included in the Investment Programme) or considered appropriate

and included in the Master Plan. The designs were considered as prepared in

accordance with the legal basis and accepted by the Consultant.

0.3. PROJECTIONS


The technical options defined to adapt water and wastewater systems to the oncoming

needs of the population are established according to the expected population

evolution and its impact on water demand and wastewater generation.

POPULATION EVOLUTION 0.3.1.

Urban population is about 47% of the total population on the designated territory,

focused in 5 main towns: towns of Kardzhali, Momchilgrad, Krumovgrad, Ardino, and

Dzhebel, while rural population is about 53%. The main tendencies in the

demographic processes are similar to the national ones.

Total population for

the district 152,808 149,041 145,382 140,316 132,904



Data from the last census show that the population covered by ViK OOD – Kardzhali

amount to 135 274 inhabitants or 88,5% of the population of the 7 serviced

municipalities. In the last 10 years the decrease rate is lower than the average for the

country. The decrease between the two censuses is approximately 4,96 % or 6 865

people.

For the entire period between 2001 and 2011, the natural population growth rate

continued to be negative, with values below the national average. Statistical data

indicates that the decline in the population served is also a result of the negative

migration growth.

In the period between 2001 and 2011, the demographic development in the

designated territory has followed the national trend towards aging of the population. In

contrast to the country, the aging processes are not so strongly expressed due to the

higher birth rate. The main factors which can have a significant influence in the future

and accelerate the processes are related to reduction of the fertile contingent

compared to higher average age of the mothers at birth, the increasing average life

expectancy and the negative migration flows.

From economic perspective the instantaneous profile of the age structure,

characterized by accumulation of productive population, gives opportunity to use the

so called “demographic dividend”, since the people in working age are about 70% of

the entire population of the designated territory.

The registered trends in the demographic processes in the region will largely

determine the future development of the population determined on the other hand by

the momentum of the demographic processes – the population of the designated

territory of ViK OOD Kardzhali will continue to decline in the short and medium term,

at a rate lower than the average national one.

WATER DEMAND 0.3.2.

Water demand has been assessed from population evolution with the main hypothesis

that for domestic consumption, individual consumption will go toward a standard value

of 120 l/c/d.

The table below shows the water demand including the physical and commercial

losses, reflecting the pressure on resource. For 2011, the overall performances of

networks are listed below (source: ViK OOD – Kardzhali).

• Town of Kardzhali: 52 %

• Town of Momchilgrad: 68 %

• Town of Krumovgrad: 40 %

• Town of Ardino: 61 %

• Town of Dzhebel: 9 %

• Village of Benkovski: 47 %



• Total for the WSS Operator: 50 %3

The performance (efficiency) objectives for the year 2038 are 80% for new networks

and 75% for already constructed networks.

WASTEWATER GENERATION 0.3.3.

Sewerage flows are estimated from the water consumption, the sewerage coverage

rate and the infiltration.

The table below does not include infiltration.

3 The NRW percentage for the whole WSSC is the ratio between the overall NRW volume

(sum for the whole WSSC) and the overall water demand including NRW (sum for the whole

WSSC).



For 2011, the levels of infiltration of the networks are listed below (source: ViK OOD –

Kardzhali).

• Town of Kardzhali: 62 %

• Town of Momchilgrad: 57 %

• Town of Krumovgrad: 53 %

• Town of Ardino: 55 %

• Town of Dzhebel: 45 %

• Village of Benkovski: 30 %

• Total for the WSS Operator: 58 %4

The performance objectives for the year 2038 include infiltration levels of 15% for new

networks and 20% for the old networks.

For more details on wastewater flow projections, see section 5.3.

Connection rate for drinking water on the designated territory is 100%. Connection

rate to the sewerage varies from 7% to 97% for the settlements with partially

constructed sewerage. Losses and infiltration levels are very important for the

respective networks and are taken into account. Designing facilities, included in the

measures proposed by the Consultant, will be carried out based on the volume of

wastewater generated as a result of water consumption by the population (not by the

water consumption at the source) and the adequate infiltration level.

At the end of the period – 2038, connection rate to the sewerage will be from 90% to

100% for the settlements with constructed sewerage.

0.4. NATIONAL OBJECTIVES AND REGIONAL TARGETS


4 The infiltration percentage for the whole WSSC is the ratio between the overall volume of

infiltrated water (sum for the whole WSSC) and the overall wastewater quantity including the

infiltrated water (sum for the whole WSSC).



As a member of the European Union since 2007, Bulgaria is committed to improve

environmental quality in order to achieve compliance with the EU Acquis

Communautaire as stated in Chapter 22 – Environmental Protection. Bulgaria has

therefore harmonised its legislation in the fields of environment, water and sanitation

with the one of the EU, and compliance with this legislation is part of the national

objectives.

On the basis of the analysis of the current situation, the Operational Programme

Environment 2007-2013 (managed by the Ministry of Water and Environment) sets the

country priority areas for the environmental sector to be implemented and financed by

the EU through the Cohesion Fund and the European Regional Development Fund.

The first priorities are given to:

• Compliance with the Water Framework Directive 200/60/EC and Directive

98/83/EC: 100% of the population should be sufficiently supplied with drinking

water of good quality.

• Compliance with the Urban Wastewater Directive 91/271/EC: every

agglomeration counting over 2,000 PE must treat wastewater in a WWTP, and

the ones counting over 10,000 PE and located in sensitive areas should be

provided with nutrient removal of nitrogen and phosphrus.

During the negotiations under Chapter 22, two transitional periods have been

negotiated with regard to the implementation of UWWD 91/271/EC: until 31 December

2010 for all agglomerations over 10,000 PE and until 31 December 2014 for all

agglomerations between 2,000 and 10,000 PE (total of 273 settlements).

On the territory of ViK OOD – Kardzhali, the national objectives apply and there is no

specific regional target.

The project objectives and legal basis as well as the relevant European Directives and

the national legislative and regulatory framework in the Republic of Bulgaria are

detailed in Chapter 1, Appendix 1-2 and Appendix 1-3

0.6. INVESTMENT PROGRAMME AND ECONOMIC ANALYSIS


Required investments have been identified and planned along three periods

corresponding each to an investment programme:

• Short Term (2014-2020)

• Medium Term (2021-2028)

• Long Term (2029-2038)

In the three sections below are presented the synthesis of the costs of the three

investment periods (short, medium and long term). Detailed costs (per water system

for water supply and per agglomeration for sewerage) are presented in Sections 6.2-

6.4. In Sections 6.2.2, 6.3.2 and 6.4.2 and drawings “Short-, medium- and long-term

investment programme” for the respective water supply systems or agglomerations

Synthesized summary tables including prioritization of measures (according to the

Consultant’s methodology for priorities presented in Appendix 4-7) along with the

associated outcomes are presented below.

Besides the investment programme the Consultant recommends that a set of studies

or programme are conducted following the submission of the present Master Plan.

These studies and programmes are not included in the investment programmes and

cannot be quantified at this stage. This set of studies and programmes includes (see

Section 6.2.1):

• Institutional studies (more details are provided in Section 6.1.2)

• Sludge management study (more details are provided in Section 4.3.1.2)

• Non-domestic wastewater management programme (more details are

provided in Section 4.3.2.1)

0.7. MACRO-AFFORDABILITY

This section relates to Chapter 5.4. of the main Report.

Macro-affordability assessment is required for determining the viability of the proposed

investments in WSS systems and establishing realistic limits of maximum investments.

Macro-affordability depends on a number of variables – type and timing of

investments, forecasted operation and maintenance expenses, established and

expected amortization policies, investments funding sources.

The affordability threshold set by Bulgarian legislation is 4% of the average household

income at minimum water consumption of 2.8 m3 per household member. Other

sources set maximum limits of 2-2.5% of the average household income. Current

calculations concerning the social affordability are made under an affordability

threshold of 4 % of the average income of the first 3 decile groups. Since the price of

the services provided by Water Supply and Sewerage OOD Kardzhali as of 2013 is

higher than this threshold one more scenario under an affordability threshold of 4% of

the income of households of the 3-rd decile has been examined. The expectations for

reducing current prices and levelling them to a threshold of 4% of the average income

of the groups with lowest income would lead to restricted investment options for

maintaining the constructed WSS systems, the quality of the services provided and

loss of the financial stability of the company. Due to these reasons and the current

practice in service price formation, such a step is unrealistic at present. The maximum

affordable tariffs at various affordability limits are shown in the table below:

Table 0-16 Affordability constraints 2016 - 2038

2011 2016 2021 2028 2038

Household size, designated territory 2.8 2.8 2.8 2.8 2.8

Average household income in EUR

(constant 2011 values) 3,147 3,653 4,301 5,404 7,484

Affordable price per m3, EUR (4% of

the average income of the first three

decile groups)

0.71 € 0.82 € 0.97 € 1.22 € 1.68 €

The affordability analysis has been made with assumptions for covering all operating

expenses and partial amortization expenses considering the funding sources.

The results concerning affordability of investments are presented in the table below:

Table 0-17 Net cash flows at an affordability threshold of 4% of the average income of the first three

decile groups, EUR

2016 2021 2028 2038

Financial flow (100% depreciation and

0% co-financing) -2,909,827 -5,472,555 -7,222,845 -3,596,474


0% co-financing) -1,242,682 -2,200,699 -2,335,889 1,290,481

Financial flow (0% depreciation of new

assets) -528,191 -798,474 -241,480 3,384,891

10% co-financing) -3,964,705 -7,804,662 -9,786,683 -4,883,083

Financial flow (0% depreciation of new

assets and 10% co-financing) -2,297,560 -4,532,806 -4,899,727 3,873

The investment may be considered affordable if revenues generated at tariffs set to

4% of the average income of the first 3 deciles are sufficient to cover the full O&M

costs and the full and/or partial depreciation of assets.

Calculations of the financial flows show that the possibilities to implement the

investment programme are realistic in a scenario excluding the depreciation of new

assets and with reduction of the investment components in the short-term and

medium-term programme.

45% of the proposed investments of 104,678,600 € for the short-term period in a

scenario excluding depreciation of new assets, 100% grant funding. In a scenario of

partial depreciation of new assets (30%) and using tariffs consistent with the average

income of the three lowest income decile groups, the accumulated shortage cannot be

overcome without reducing the amount of the investment programme. In this scenario,

the potential amount of the investment component is within € 26,169,700 or 25% of

the short-term programme. In case of full depreciation the possible investment

solutions is very limited. It is expected that tariffs will increase by nearly 46.4 %

reaching 0.82 EUR/m3 by 2016.

The proposed investment of 119,737,800 € in medium-term plan is feasible at 75% (€

89, 803,400) without accounting the depreciation of the new assets and at a threshold

of 4% of the average income of the first three decile groups and when reducing the

investments in the short term by approximately 2%. In order to implement the

programme, the tariffs should reach 0.97 EUR/m3. In case of partial depreciation

(30%), the possible volume of implementation is approximately 28% or € 33,526,612.

The affordability of the long-term programme amounting to EUR 120,617,200 depends

on the level of implementation of the previous two programmes. The planned

investments may be made in a scenario of 100% grant funding and without

considering depreciation of new assets in reduction of the short-term and medium-

term programme, as described above. In a scenario of partial (30% ) depreciation the

programme is feasible at 43% (€ 51,865,400). It is expected the implementation of the

long-term programme will make service prices reach 1.22 EUR/m3 in 2028.

The results of the macro-affordability analysis of investment programmes lead to the

conclusion that their full implementation requires to provide options for using higher

tariff levels, formed at a threshold of 4% of the income of the third decile in certain

periods. Thus, depreciation of new assets may be covered without jeopardizing the

financial stability of the Operator.

The expected increase in tariffs will put significant financial pressure on lower income

households and lead to lower collection rates. Appropriate incentive schemes need to

be established for lower income households in order to achieve the outlined objectives



and meet the quality requirements for services provided in the field of water supply

and sewerage systems.

0.8. PRIORITIZATION OF INFRASTRUCTURE INVESTMENTS


Infrastructure investments have been designed to address the deficiencies identified

in the current situation analysis and forecasted needs (see summary tables 0-18 and

0-19 for summarized data on the current situation for water supply and sewerage and

the compliance with EU directives). All infrastructure projects identified in the

investment programmes have been prioritized.

The prioritization consists in calculating an amount of points5 for each investment,

based on the following factors:

• The size (population / population equivalent) of the settlement /

agglomeration;

• The economic efficiency (cost per inhabitants / cost per equivalent inhabitant);

• The current service coverage;

• The investment readiness to date;

• The importance of the investment implementation according to the Water

Framework Directive / Urban Wastewater Directive.

The details of the methodology for prioritization are given in Appendix 4-20.

The implementation of this prioritization results in one list of prioritized investments for

each investment programme period. They can be seen in detail in:

• Table 6-6 for the short-term investment programme

• Table 6-11 for the medium-term investment programme

• Table 6-16 for the long-term investment programme

1. INTRODUCTION

1.1. PROJECT FRAMEWORK

GENERAL FRAMEWORK AND POLICY CONTEXT 1.1.1.

Bulgaria, as member of the European Union (EU), is committed to improve

environmental quality in order to achieve compliance with the EU Acquis

Communautaire. In this respect, Bulgaria has adopted most of the Acquis in the field

of environmental protection. The fulfilment of the commitments made by Bulgaria in

the negotiation process for Chapter 22 – Environmental Protection, involves the

implementation of major investment projects in environmental infrastructure.

Before Bulgaria’s accession to EU, part of the funds needed for environmental

investments were available through different European programmes (i.e. PHARE,

ISPA, SAPARD) or through projects financed by International Financing Institutions

(IFIs) (like: EBRD, EIB, WB, etc.). After 1st of January 2007, Bulgaria has continued to

receive EU financial support from the Structural and Cohesion Funds (SCF).

In order to ensure an efficient absorption and use of EU funds, the Bulgarian Ministry

of Environment and Water (MoEW), as Managing Authority for the Operational

Programme (OP) “Environment”, prepared a strategic document for the programming

period 2007 – 2013 developed in line with the Community Strategic Guidelines (CSG);

the National Development Plan (NDP); the National Environmental Strategy 2005-

2014; the National Strategic Reference Framework (NSRF); the National Waste

Management Programme 2009-2013; the National Strategy for Management and

Development of the Water Sector 2004 – 2015; and the programmes for the

implementation of the requirements of different “heavy” directives, elaborated in 2003,

such as 91/271/ЕЕС concerning urban waste water treatment.

On the basis of the analysis of the current situation, the OP “Environment 2007-2013”

sets the country priority areas for the environmental sector to be implemented and

financed by the European Union through the Cohesion Fund and the European

Regional Development Fund. Priority axis 1 concerns the improvement and

development of water and wastewater infrastructure in settlements with over 2,000

population equivalent (PE) and in settlements below 2,000 PE within urban

agglomeration areas. The priority axis is based on the purpose of Council Directive

2000/60/EC laying down the framework for community activities related to water -

Water Framework Directive (WFD) as well as the purposes of Council Directive

91/271/EEC for urban waste water treatment.

During the negotiations under Chapter 22, two transitional periods have been

negotiated with regard to the implementation of the requirements of Directive

91/271/EEC, which are as follows:

• Till 31 December 2010 – for all agglomerations over 10,000 PE (85 no in

total);



• Till 31 December 2014 – for all agglomerations between 2,000 and 10,000 PE

(273 no in total).

This requires measures that include:

• Water supply: extension, reconstruction, modernization, NRW reduction

programmes, as well as construction of Drinking Water Treatment Plants

(DWTP), reservoirs.

• Sewerage: extension, reconstruction and modernization, as well as

construction of new sewerage systems including urban Waste Water

Treatment Plants (WWTP), septic tanks, soak ways.

According to the Report for Implementation of Directive 91/271/EEC by the end of

2010 issued by the MoEW, there is a delay in the fulfilment of the Directive

requirements for agglomerations above 10,000 PE. This imposes to give first priority

to the design and construction of sewerage networks and urban WWTP for

agglomerations over 10,000 PE.

Joining the EU in 2007, Bulgaria was urged to reform the water sector and adopt

stricter regulations and environmental standards. The European Commission

requested from Bulgarian an urgent action plan for reform in the water infrastructure

sector. As a result, the Ministry of Environment and Water prepared a strategy and

completed a map for the water supply and sewage sector development, in

coordination with other ministries, regional authorities, municipalities and ViK

operators for most efficient planning, management and operation of the water

infrastructure.

At present, the water operators providing water supply and sewerage services in the

country are state, municipal or mixed commercial companies, which face the

challenges of the reform launched in the water sector, and triggered by the need to

resolve the fragmented ownership of water assets. The reforms in the water sector

envisage that the ownership on water infrastructure should be public state and public

municipal, while the management of water supply and sewerage system should be

performed by the water supply and sewerage associations.

This Master Plan (MP) is the first important step giving the framework for the

development strategy of the municipalities in the water supply and sewerage sector for

the period 2014-2038. An identification of necessary investment measures to achieve

full compliance with relevant EU Directives and other objectives defined in the Terms

of Reference is given in the present document, as well as a prioritisation and phasing

of these measures in short, medium and long term. Special attention is paid to the

preparation of the short term investment programme intended to be financed by the

next Operational Programme “Environment 2014-2020”.



PROJECT OBJECTIVES AND SCOPE OF WORK 1.1.2.

The project objectives and scope of work below have been defined in accordance with

the Terms of Reference of the “Regional water and wastewater Master Plans for the

central region”.

The Government of Bulgaria has received a loan from the World Bank to implement a

Municipal Infrastructure Development Project. Its strategic aims are to

a) improve the reliability and quality of water provision to the communities in

selected settlements in the project area and

b) assist municipalities to improve investment-planning capacity.

These objectives are in line with Bulgaria’s National Strategy on Environment (2005-

2014), which pursues the following goal: “To provide good quality and sufficient

quantity of water for different purposes”.

There are three project components:

• Component 1: Project Implementation Support;

• Component 2: Technical assistance for Regional and Municipal Infrastructure

Development;

• Component 3: Completion and Rehabilitation of Dams.

This assignment covers Component 2 under which the project will support the

Strategy for Water Supply and Sewerage Management and Development in the

Republic of Bulgaria through the preparation of 24 Regional Master Plans for water

supply and sewerage systems for the designated territories in the Central region with

a planning horizon of 2038. According to a first assessment based on 2011 population

census and in compliance with the Terms of Reference for the project, the Master

Plans should focus on 143 settlements above 2,000 PE. Small settlements will be

taken into account at general level within the activity of the Water Supply and

Sewerage Companies (WSSCs) and the situation assessment. The plans will be the

first step for identification of priority investments for rehabilitation of existing facilities

and construction of new facilities for water supply and wastewater collection and

treatment needed to cover the requirements of the EU Directives concerning the

environment.

The present report aims to prepare a Master Plan for the water supply and sewerage

systems of the designated territory of the Water Operator i.e. ViK OOD - Kardzhali,

serving the Municipalities of Ardino, Dzhebel, Kirkovo, Krumovgrad, Kardzhali,

Momchilgrad, Chernoochene from Kardzhali District. The territory includes 471

settlements: 1 settlement with population above 10 000 inhabitants and 5 settlements

with population between 2 000 and 10 000 inhabitants.

Settlements with population above 2 000 inhabitants from the specified territory are

presented in the following table according to the “Report on the Application the

Requirements of EU Directive 91/271/EEC” issued by the MoEW.

In Appendix 2-2 are listed all settlements on the territory of ViK OOD – Kardzhali.

The Master Plan has the following objectives:

• Assess the current state of water and wastewater systems;

• Enable the preparation of feasibility studies for individual investment projects;

• Ensure compliance with the Environmental Acquis and all current EU

directives, in particular the Water Framework Directive and the Urban

Wastewater Directive within the committed deadlines;

• Ensure efficient use of water resources;

• Facilitate co-financing from EU grants (Cohesion Fund);

• Build capacity for project preparation at regional/local level;

• Define short (2014-2020), medium (15 years horizon) and long term (25

years) investment programmes;

1.2. INSTITUTIONAL AND REGULATORY FRAMEWORK

GENERAL ADMINISTRATIVE FRAMEWORK 1.2.1.

The main responsibilities for water management and water supply and sewerage are

shared among the following institutions:

The Ministry of Regional Development and Public Works is responsible for the

overall policy related to the design, construction and operation of water supply and

sewerage systems in the country. The Minister represents the state in water supply

and sewerage companies with over 50% state share. The Ministry also coordinates

water association activities and provides methodological guidance on the preparation

of the water supply and sewerage Master Plans.

The Ministry of Environment and Water (MoEW) is responsible for the management

and the distribution of water resources at the national level. The Minister issues the

permits for water-taking of mineral water – exclusive state property. The MoEW is also

responsible for environmental protection and the implementation of the Operational

Program Environment, under which water and wastewater infrastructure is funded.

The Council of Ministers defines the state policy in the water supply and sewerage

sector as part of the country's water policy and the National strategy for development

and management of the water sector in Bulgaria. The Council of Ministers approves a

Strategy for development and management of the water supply and sewerage sector

in Bulgaria for a period of at least 10 years. The strategy defines the main objectives,

priorities, stages and necessary resources and sources of funding for the construction

and development of water supply and sewerage systems and for improvement of

water supply and sewerage service quality. The policy in the water sector is

implemented by: 1. The Minister of Regional Development and Public Works, 2.

Municipal councils and mayors of municipalities.

The Ministry of Health is responsible for the control on the quality of water intended

for drinking and household needs, the quality of mineral water intended for drinking or

used for prophylactic, therapeutic and hygienic purposes, including bottled mineral

water in the commercial network and the quality of water intended for bathing.

Basin Directorates undertake water management at the basin level. There are four

basin directorates: (i) Danube Basin Directorate – Pleven, (ii) Black Sea Basin

Directorate – Varna, (iii) West Aegean Basin Directorate – Blagoevgrad and (iv) East



Aegean Basin Directorate – Plovdiv. Directorates develop River Basin Management

Plans and Flood Risks Management Plans. They are also responsible for issuing

permits for water use and abstraction, for controlling the compliance with the

parameters set in these permits, for controlling the activities in river beds, and for

water quantity and quality monitoring. Their management of water is based on basin

principles.

Water Associations are non-profit legal entities. They manage water supply and

sewerage systems within the boundaries of a designated territory in the cases where

water supply and sewerage system ownership is divided either between the state and

one or more municipalities or among several municipalities. If the WSSC system,

which falls within the specified territory, is the property of a single municipality, the

management is performed by the municipal council.

The governing bodies of a Water Association include a General Assembly, which

consists of representatives of the state (District Governor), and the municipality(ies),

with the district governor being the chairman. In the cases where the state and more

than one municipality participate in the Water Association, the state is entitled to 35

per cent of the votes, and the other 65 per cent of the votes are allocated among all

municipalities in proportion to their population. The funds necessary for the Water

Associations operation are provided by the state and municipalities according to the

proportion of their voices.

Regarding the Water Act, Water Associations are responsible for the preparation of

the regional Master Plans and the investment programmes attached to the plans.

Assignment and approval of these specific Master Plans is made by the MRDPW. The

regional Master Plans are accepted and approved by the MRDPW only after they are

endorsed by the respective Water Association or Municipal Council.

Water supply and sewerage companies (WSSC) (referred to as ViK, VKS, VKTV or

INFRASTROI in the Central Region) are responsible for the operation, management

and maintenance of water supply and sewerage facilities in the settlements as well as

the provision of water supply and sewerage services to consumers. A WSSC is a

commercial, state or municipal company – a legal entity, which has signed a contract

with the chairman of the corresponding Water Association or with the mayor of the

respective municipality. The term of the contract with a WSSC, signed in accordance

with the Water Act, cannot be longer than 10 years, provided that it does not include

an obligation for the WSSC to build new water and sewerage infrastructure; or 15

years, if it obliges the WSSC to undertake construction of new infrastructure. In all

other cases, the procedure and selection of a water operator as well as the signature

of the contract is carried out in accordance with the Concession Act.

Municipalities are direct beneficiaries of the OP "Environment". The mayor of a

municipality develops and implements the policies related to planning, management,

construction, reconstruction and modernization of water supply and sewerage

networks and facilities that are municipal property.

Municipal councils control the municipal participation in water supply and sewerage

companies (in those companies, in which the municipalities have shares). They also



approve municipal development plans and mayor’s statements regarding the business

plans developed by WSSCs.

The State Energy and Water Regulatory Commission (SEWRC ) is responsible for

regulating the tariffs, affordability and quality of water supply and sewerage services

under the Water Supply and Sewerage Services Regulation Act.

The Environmental Executive Agency under the Minister of Environment and Water

guides the National environmental monitoring system.

The service performance regulation is performed at two levels – external and internal.

The external regulation is performed by the State Energy and Water Regulatory

Commission. The regulation principles are set in the Ordinance on the long-term, the

conditions and the order for the annual target levels of the indicators of water supply

and sewerage services quality. The internal regulation is performed by the company



stakeholders through the general principles set in the Commercial Act, the Regulation

on the Order for Execution of the Rights of the State in the Commercial Companies

with State Share in the Capital, the company’s Constitutive act and the contract for

management assignment.

The Water Supply and Sewerage Services Regulation Act establishes the legal

framework for the regulation of prices, accessibility and quality of water-supply and

sewerage services provided by the water supply and sewerage companies.

The prices and quality of water supply and sewerage services are regulated by the

State Energy and Water Regulatory Commission (SEWRC ), regardless of the

forms of ownership and management of water supply and sewerage systems. The

Commission is guided by the following principles:

1) Ensuring conditions for provision of universal access and social affordability of

water supply and sewerage services;

2) Prevention of abuse of dominant position;

3) Protection of consumer interests;

4) Economic justification of water supply and sewerage services prices;

5) Taking into consideration the needs of consumers placed at a disadvantage

for geographic, ground or other reasons;

6) Creation of conditions for water and sewerage operators to operate and

maintain the system and to make investments upon reduction of operating

costs;

7) Encouragement of expedient and effective planning of investments in time;

8) Speed and procedural economy of proceedings before the Commission;

9) Encouragement of reduction of water losses, efficient and economic use by

consumers of the water quantities delivered;

10) Environmental protection;

11) Creation of conditions for attraction of resources for investment and

participation of the private sector in the provision of water-supply and

sewerage services;

12) Encouragement of introduction of modern technical methods and

achievements in the provision of water-supply and sewerage services.

SEWRC measures and assesses the quality of water supply and sewerage services

by means of the following quality indicators:

1) Coverage rate of water supply services;

2) Drinking water quality;

3) Non-interruption of water supply (uninterrupted water delivery and duration of

disruptions);



4) Total water losses in the water-supply systems and time limits for the

reduction thereof;

5) Water supply system breakdowns;

6) Water supply system pressure;

7) Sewerage service coverage rate;

8) Raw wastewater and treated wastewater quality;

9) Sewerage system breakdowns;

10) Flooding of third party corporeal immovable caused by the sewerage system;

11) Operational indicators of efficiency;

12) Financial indicators of efficiency;

13) Time limit for reaction to written complaints by consumers;

14) Time limit for connecting new consumers with the water supply and sewerage

systems;

15) Staff size in proportion to the number of consumers serviced.

The Commission regulates prices by setting an upper limit for prices or for revenues

and a rate of return. Price regulation methods, pricing rules reflecting the structure of

costs, the procedure for price proposal submission and for the endorsement thereof,

as well as the procedure for disclosure of information, are determined by an ordinance

adopted by the Council of Ministers on a motion by the Commission. WSSCs submit

the prices formed according to this ordinance to the Commission for endorsement.

The prices proposed by the WSSCs may not be higher than the prices endorsed by

the Commission. The tariff is proposed for each planning period. The application must

be submitted not later than four months before expiration of the old price period or the

coming into force of the proposed approval or change of the approved price.

LEGAL ASPECTS OF FUNDING OPPORTUNITIES 1.2.5.

After amendments were made to the Water Act in 2009, it was decided that the

ownership of the former state and municipal water companies would be removed from

their assets and become public state and public municipal property to be managed by

water associations. The purpose of the change was to encourage the utilization of

funds under Operational Program "Environment" and to use EU funds for renovation

of the water infrastructure. The upgrade and construction of water and wastewater

treatment infrastructure is set as Priority 1 of OP "Environment". 71.3 % of the total

financial package or nearly EUR 1.3 billion has been allocated to this priority for the

period 2007-2013. 80 % of this amount, i.e. EUR 1.03 billion is provided by the

Cohesion Fund of the EU and the remaining amount – by the national budget. Funding

for the water sector is also provided under the National Plan for Rural Development

(EUR 600 million), the Regional Development Operational Programme (EUR 150

million), the pre-accession programme ISPA (unallocated funding for 2007-2010 to the



amount of EUR 300 million), the World Bank (over EUR 100 million). The projected

investments from the private sector are expected to amount to EUR 2 billion.

When one or more municipalities apply for European Union funds for reconstruction

and modernization of water supply and sewerage facilities - public state property, they

make a request to the Minister of Regional Development and Public Works for a

change of the facility ownership, indicating the program, the name of the procedure by

which proposals will be submitted and the deadline for their submission, if such is

defined. The Minister of Regional Development and Public Works, within one-month

period from the submission of the request, submits a draft decision to the Council of

Ministers for a change of the facility ownership from public state to public municipal.

By decision of the Council of Ministers the ownership of the facility is granted to the

municipalities, provided that it is reconstructed or modernized in whole or in part with

funds received under programs financed by European Union funds.

The municipal budget is the main financial plan of a municipality for a fiscal year and

its framework must be robust and adaptable, allowing the municipality to accumulate

substantial resources in support of its municipal priorities and initiatives. Since 2003,

municipal budgets are drawn up and implemented under the conditions of fiscal

decentralization. The division of expenditure responsibilities between the state and

municipalities increased the responsibilities of the municipalities for determining their

own revenue, which is the main source of funding of municipal activities. Municipal

budgets are developed in accordance with Art. 11 of the Municipal Budgets Act, the

State Budget Act of the Republic of Bulgaria, Decision № 937/08.12.2009 of the

Council of Ministers, and the local regulations in force, adopted by decisions of the

local Municipal Council.

The strategic development plan of a municipality is the main document determining

the strategic objectives and priorities of the municipal policy, developed in accordance

with the requirements of the Law on Regional Development and the National Strategy

for Regional Development of the Republic of Bulgaria for the period 2005-2015. The

plan is the starting point for directing the efforts of the municipal management and all

interested parties in the municipality to reach the objectives of that development and

turn the strategic planning into a main instrument for the development of the

municipality.

The Municipalities allocate the reported and expected capital expenditures in their

annual budgets by indicating in the sources of finance without the required additional

external financing. Capital expenditures are financed by three lines – from the budget

of the municipality, a targeted subsidy from the state budget and external financing -

borrowed funds for projects.

Generally, the expenses planned for capital investments are insufficient and cannot

provide adequate financing of water sector projects. In all cases, external financing in

the form of loan capital is required in order to ensure own funding and to cover the

need for working funds within the project implementation period.

The expected revenue in the budget of the Municipality of Kardzhali for 2013 amount

to EUR 20 415 884,81 (BGN 39 930 000). Main part of the revenue is formed of state



transfers for financing activities delegated by the state amounting to EUR 10 265

120,69 (BGN 20 076 83). Investment programme /without secondary contractors/

amounting to EUR 3 361 588,17 (BGN 6 574 695), with funds allocates for

constructing sites on the territory of the municipality and for major repairs. The funds

for realizing the investment programme are provided from:

• Target subsidy for capital expenditures to the amount of EUR 677 001,58

(BGN 1 324 100), of which EUR 309 996,27 (BGN 606 300) are allocated for

major repairs and construction of municipal roads;

• Own revenue to the amount of EUR 1 533 875,64 (BGN 3 000 000)

For 2013 expected capital expenditures for the Municipality of Momchilgrad amount

to EUR 553 301,16 (BGN 1 082 163). About 33% (EUR 180176,19) of the envisaged

investments should be provided by own funds. The remainder of the investment

programme amounting to EUR 330 652,46 is provided by target subsidy from the

central budget and other sources. The projects planned for realization in the WSS

sector amount to EUR 88162,06 (BGN 172 430) or about 16% of the funds envisaged

for capital expenditure. The projects planned in the sector divided by source of funding

are presented in the following table:

CONCLUSIONS AND RECOMMENDATIONS 1.2.6.

As a member of the European Union, Bulgaria has harmonised its water and

environmental legislation with the one of the EU. The European legislation in the field

of water management is transposed to the Bulgarian legislation by means of the Water

Act and the regulations for its implementation.

The effective policy in the water supply and sewerage sector is the most important

commitment of Bulgaria joining the EU. The main investment and management tool of

the Government in this area is the OP "Environment", by means of which the sector

can be financially supported by EU funds. Municipalities were defined as the sole

beneficiary of this funding.

For the purposes of effective management, planning and construction of water supply

and sewage systems and the provision of water supply and sewerage services, the

territory of the country has been divided into 51 designated areas. Their limits and

coverage are essential for the formation of the water associations, which provide

integrated management of water systems consisting of two main groups of ownership

of the water assets - public state and public municipal property.

The planning of the development of the water supply and sewerage systems is done

by means of Master Plans and Long-term investment programs. In these plans and

programs are included all settlements in the designated territory, pursuant to the

Technical design, with more detailed analysis of water supply part for settlements with

population above 2000 inhabitants and of the sewerage part for agglomerations with

over 2,000 equivalent inhabitants. The Master Plans are prepared for a period of 25

years. The scope of work for the plans and programs includes performing a

comprehensive analysis of the conditions of the water supply and sewerage systems

and facilities, setting objectives and priorities for the development of water supply and

sewerage systems and the development of short and long-term investment programs.

One of the main requirements for the plans is that they contribute towards meeting the

requirements of the European Directives for the use and treatment of water, and to

ensure the effectiveness of public investment in the water infrastructure.

Numerous stakeholders are involved at the national, regional and local levels.

Ministries play a significant role at the national level: The Ministry of Environment and

Water is responsible for the management and distribution of water resources, while

the Ministry of Regional Development and Public Works is in charge of the overall

policy related to the design, construction and operation of water supply and sewerage

systems. The MRDPW also drives the preparation of the regional water supply and

sewerage Master Plans and approves them. Basin Directorates undertake water

management at the basin level and regulate permit issuance for water abstraction. At

the local level, municipalities formulate and implement the water sector policy.

Besides, Water Supply and Sewerage Companies are commercial, state or municipal

companies that operate and maintain water supply and sewerage facilities. They are

contracted by municipalities or by Water Associations. The latter are non-profit legal



entities, which manage water supply and sewerage systems, when the systems’

ownership is divided either between the state and one or more municipalities or

among several municipalities. Regarding the Water Act, Water Associations are also

responsible for the preparation of the Regional Master Plans and therefore must

endorse them before approval of MRDPW. The regulation of water tariffs, affordability

and quality of water supply and sewerage services is undertaken by the State Energy

and Water Regulatory Commission.

Since commercial entities, such as WSSCs, cannot apply for EU funds, Water

Associations may undertake this responsibility as non-profit legal entities. Therefore, a

procedure has been implemented so that the ownership of water and sewerage

facilities can be transferred from state and municipal companies to Water

Associations. The Ministry of Regional Development and Public Works receives

requests, which must be subsequently approved by decision of the Council of

Ministers. This procedure aims to facilitate the implementation of the OP Environment

and the use of EU funds for reconstruction and modernization of water supply and

sewerage infrastructure.

The regulatory framework is based on a few texts. The main legal act is the Water Act

(1999) which sets out the relations in the management of water as a nation-wide

resource and regulates the state policy for the operation, construction, reconstruction

and modernization of water supply and sewerage infrastructure. The scope of the

Water Act spans interdisciplinary fields: It regulates for example water body statuses,

issuance of permits for water uses and water intakes, land easements, water

protection, financial and economic organization in water management, administrative

and citizen responsibilities etc. It is supported by 14 ordinances, that specify terms

and conditions or requirements for specific activities related to water. This Water Act is

to be amended and supplemented in the future, as a Draft Law has already been

prepared in April 2012. Those new components of the Water Act come mainly from

the transposition of European Union Directives. Along with the Water Act, two laws

complement this regulatory framework: The Environment Protection Law (2002) for

questions related to environmental components (including air, water, soils, ground,

landscape, and biodiversity) and the Regulation of Water Supply and Sewerage

Services Act for prices, accessibility and water supply and sewerage services quality.

2.1. PROJECT AREA

MASTER PLAN STUDY AREA 2.1.1.

There are 471 settlements on the territory of Kardzhali District administratively divided

into seven municipalities as follows:

• Ardino Municipality: 52 settlements;

• Dzhebel Municipality: 48 settlements;

• Kirkovo Municipality: 73 settlements;

• Krumovgrad Municipality: 80 settlements;

• Kardzhali Municipality: 118 settlements;

• Momchilgrad Municipality: 49 settlements;

• Chernoochene Municipality: 51 settlements.

The region of the Master Plan covers all municipalities on the territory of Kardzhali

District. Water Supply and Sewerage OOD – Kardzhali is the only WSS Operator in

Kardzhali District. 244 of all 471 settlements are serviced by ViK OOD – Kardzhali.

The territory served by “Water Supply and Sewerage” OOD – Kardzhali is situated in

the Southern Bulgaria and falls within the South Central Planning Region (NUTS 2).

NUTS 2 (“Nomenclature of Units for Territorial Statistics”) is a hierarchical system for

single classification of territorial units in the official statistics of EU member states. The

classification under this system is the basis for allocation of aids from the EU regional

policy funds. The administrative units of the member states (regional authorities

having powers in the management of certain territorial unit) underlie NUTS system.

Kardzhali District has an area of 3 209,1 sq.km., which represents 2,9% of the

territory of the Republic of Bulgaria. It borders Smolyan District to the west, Plovdiv

District to the north, Haskovo District to northeast, and the state border with the

Republic of Greece to the south and southeast. The border location of the district is

favourable for its development. Mainly this location accounts for the significant

potential of the district for trans-border cooperation. Pan-European Transport Corridor

Municipality is a principal administrative and territorial unit of local self-government. It

is a legal entity entitled to ownership and a separate municipal budget. The municipal

administration implements executive and operational functions in compliance with the

State Budget of the Republic of Bulgaria Act.

Municipalities have an important role in the practical implementation of the regional

development strategy. Reflecting the common European tendency, more and more

powers are being transferred from the central to the local governments. This process



of decentralization is also determined by the fact that local government is most familiar

with the state and the problems of the, technical infrastructure, the environment, etc.

within the territory of the respective municipality and in most cases is the one closest

to offering adequate solutions.

More detailed administrative data for the settlements in the designated territory of

“Water supply and Sewerage” (ViK) OOD Kardzhali are presented in Appendix 2-2:

Administrative data.

RIVER BASINS 2.1.3.

Water resources in the designated territory of ViK OOD Kardzhali are formed by

underground and surface water sources, which are supplied by precipitation. The main

artery of the designated territory of VIK OOD Kardzhali is Arda River. Arda River is the

biggest Rhodopian river and is one of the biggest tributaries of Maritsa River. It and all

its tributaries are characterized by high torrentiality due to a combination of

Continental and Mediterranean climatic influence.

Due to the favorable topographical and hydrological conditions on the one hand and

the development of intensive agriculture on the other, preconditions have been

created for the realization of significant and diverse hydraulic engineering in the river

basins and high utilization and exploitation of the rich surface and groundwater

resources. Water consumption includes the needs for power generation, domestic-

drinking and industrial water supply, and agriculture.

The designated territory of VIK OOD Kardzhali includes parts of the catchment areas

of the rivers Arda, Varbitsa, Krumovitsa, Borovitsa, Perperek, Kioshdere,

Davidkovska, Kosma dere, Byukdere, Harmanliiska, Byala reka, etc. and their

tributaries, which are the main water arteries within this territory. In the valley of the

rivers included in the designated territory of VIK OOD Kardzhali two major hydro-

energy facilities are built (Studen Kladenets Dam and Kardzhali Dam with two HPP

under them) and 22 micro-dams, used for irrigation. The use of surface waters is

formed mainly by the water economic sub-sectors of irrigation, water supply and

hydropower.

Arda River springs from the peak Ardin Vrah, runs through a deep valley to the

Turkish-Bulgarian border and flows into Maritsa River on Turkish territory near the city

of Edrine. Its catchment area is 5,201 km² to the border. The length of the Arda River

to the border is 241 km, 178 km of which are within the designated territory of VIK

OOD Kardzhali. In this area 13 larger tributaries flow into Arda River. On the territory

of the municipalities of Kardzhali and Momchilgrad is built “Studen Kladenets” Dam

with total capacity of V= 489 . 106 m3, and on the territory of the municipalities of

Kardzhali and Ardino – “Kardzhali” Dam with total capacity V= 532.9 . 106 m3,. Both

dams are part of “Dolna Arda” cascade.

Borovitsa River – it springs north of Elvarnika Peak (1714,8 m), in the northern part

of the Prespanskiya part of the Rhodopes. The length of the river is 42 km, and its

catchment area is 300.6 km2, which falls entirely in the designated territory of ViK

OOD Kardzhali. Its larger tributaries are the rivers: Yailadere, Murovska, Elenevska,



Chatar, etc. Borovitsa Dam (total capacity of 27,3 million m3), used for domestic

drinking water supply of 47 villages in the municipalities of Kardzhali, Momchilgrad

and Chernoochene is built at Borovitsa River.

Varbitsa River is the longest and the most water abundant tributary to Arda River

flowing entirely through the territory of the municipalities of Smolyan and Kardzhali. Its

catchment area is 1203 km2, 775 km2 of which are in the designated territory of ViK

OOD Kardzhali. The total length of the river is 98,1 km. Its main tributaries are

Nedelinska River and Alamovska River.

Krumovitsa River springs southeast of Smaila Peak (867,5 m) near Makaza

mountain pass in Southeast Rhodopes. The length of the river is 58,5 km. Its

catchment area is 670,8 km2, 100% of which is in the designated territory. Its larger

tributaries are the rivers: Ositska, Kalabatska, Vetritsa, Kurtuldzha, etc.

Harmanliyska River (Velichka ) springs southwest of Kaleto Peak (810 m) in the

Eastern Rhodopes. It flows into Maritsa River near the town of Harmanli. The total

length of the river from its source to its outflow is 91.9 km and its catchment area is

956.3 km², 50% of which falls on the territory of Chernoochene Municipality. Its larger

tributaries are the rivers Haskovska, Yurukdere, Uzundzhovska etc.. On Harmanliyska

Riever and its tributaries are built 21 dams with a total volume of about 126 million m³.

The flow of the river is regulated mainly by Trakiets Dam (total volume of 114 million

m³), intended for irrigation.

Byala River springs near the village of Chernichevo, KrumovgradMunicipality. Its

catchment area within Bulgarian territory is 448 km² and the length is 72.3 km. It has

about 13 major tributaries located symmetrically about the main river. Among the

larger ones are: Kokardzhadere, Arpadere, Hambardere, Yuruklerska and Luda Reka.

In the valley of Byala River are built three irrigated fields.

More detailed characteristics of surface water sources is given in Chapter 3.1.2 and

Appendix 3-1.



2.2. NATURAL FEATURES

GEOGRAPHICAL FEATURES 2.2.1.

Figure 2-2 Natural features - East Rhodopes

Kardzhali District occupies the bigger part of the Eastern Rhodopes. The landscape of

the region is mainly mountainous and semi-mountainous. The highest peaks are

Veykata Peak (1463 m) in the southern part, and in the western part – Alada Peak

(1241 m) and Chilyaka Peak (1450 m). The terrain of the district is crossed by the

upper and middle valley of Arda River and its tributaries – the rivers of Varbitsa,

Ardinska, Perperek, Krumovitsa.

As per the geographic zoning of the Republic of Bulgaria, Kardzhali District is situated

in the East Rhodopes sub-region of South Bulgaria. This subregion covers the low

mountain hilly landscape along the middle valley of Arda River. The average altitude is

329 m.

On the territory of the municipalities there are deposits of lead and zinc ores in the

municipalities of Momchilgrad and Ardino, of gold near the town of Krumovgrad and of

chrome ore in the region of the village of Dobromirtsi, Municipality of Kirkovo. In the

Kardzhali District there are significant in size deposits of non-metallic minerals – the

only deposits in the country of bentonite near the town of Kardzhali and of perlite in

the Municipality of Dzhebel.

The district is rich in water resources, and two of the biggest dams in the country –

Kardzhali Dam and Studen Kladenets Dam, are constructed on its territory.

CLIMATE CHARACTERISTICS 2.2.2.

The climate is Transitional continental to Transitional Mediterranean due to the

character of the atmospheric transfer and transformation of air masses on the relief

surface. The average annual temperature is around 12-13°C, and annual

precipitation is within 700-800 mm. Winters are relatively mild, and the days with



lasting snow cover are about 39. The summer is long-lasting and hot, the maximum

temperatures reach 39-40°C.

Regarding the climate, the designated territory falls within the Transitional

continental sub-area of the European continental climate area, and at a national

level – in the south climate area and more precisely in the East Rhodopes climate

region, which is influenced by the warm Mediterranean air currents.

The average winter temperature is about 0 °C, and during the summer – about

24°C.

The climate is one of the prerequisites providing the designated territory with natural

surface and groundwater.

The morphographic features of the region have a big influence on the rainfall

pattern. The main precipitation is in the autumn-winter period under the influence of

the Mediterranean cyclones.

Table 2-3 Average values of the climate features

Feature Minimum Maximum

Average monthly

temperature -0.8 23.4

Average monthly

precipitation 30 mm 82 mm

The prevailing winds are from the North-Northwest and South-Southwest. The

average wind velocity is 1,66 m/s, which defines it as light wind.

ENVIRONMENTAL AND ECOLOGICAL FEATURES 2.2.3.

The main contribution to the pollution of air, water, and soil have:

- Industrial enterprises in the settlements, where the requirements of the

ecological legislation are not followed;

- Agriculture and stock breeding activities without applying best production

practices;

- Disposing waste at unregulated waste landfills;

- Unregulated storage and keeping of fertilize masses from the stock-breeding

farms;

- Unsolved problems of the pesticides storages;

- Poor condition of sewerage networks and their facilities – no sewerage or

sewerage with expired useful life, lack of modern highly efficient treatment

facilities for wastewater from the industrial enterprises and the settlements.

Air 2.2.3.1.

Potential air polluters in the designated territory serviced by ViK OOD-Kardzhali are

the big industrial companies located in the municipal town of Kardzhali and in some

other settlements, however under strict control and efficient management many of the

harmful emissions can be reduced to values complying with the requirements of the



acting legislation. In the region of the town of Kardzhali the bigger pollutants are “S

and B Industrial Minerals” AD, “OTsK” AD (when active). In the region of the

municipality of Momchilgrad air pollutants are: “Perlit” AD plant – perlite processing,

“Vinifera” OOD greenhouses and the asphalt bases of “Parstroiingenering” AD (new

treatment facilities are mounted) and “Stroitelstvo I remont” EOOD. Air pollutants in

the other municipalities are production emitters with lesser significance for the air

pollution. Of significance for the distribution and dispersion of the air pollutants are the

landscape and the altitude, the gradient and exposure of the slopes, which determine

the distribution of heat, light, precipitation quantity and humidity, wind. The existence

of local ground transfer of air masses along the basin of Arda River in east-west

direction also contributes to the accumulation of pollutants in the atmospheric basin

during some periods of the year. In certain meteorological conditions / sustained wind,

fog, low clouds/ in the ground level are accumulated pollutants of fine particles /FP/ -

FP10, sulphur dioxide and other pollutants exceeding the maximum allowable norms.

Additional factor for the deteriorated air quality in the settlements is: emissions from

transport, local combustion sources, domestic heating, as well as secondary air

pollution with dust as a result of irregular cleaning and washing of the road network.

The efforts of the local authorities are directed towards rehabilitation of the road

network and improving traffic organization. The petrol stations on the territory of the

district are in compliance with the legal requirements.

In the municipalities of Kardzhali District there are developed programs for emission

reduction and reaching the set norms for harmful substances in the areas for

assessment and management of air quality.

Soil and land resource 2.2.3.2.

Soils and agricultural lands are the main natural resource underlying economic

development (development of agriculture, animal breeding and use of raw materials

for food industry development).

There are good prerequisites for development of agriculture, stock breeding and food

industry. The introduction of good agricultural practice, the provision of controlled

fertilization, the prevention of unauthorized accumulation of manure masses from

animal farms and of solid domestic waste, etc. will ensure soil and water protection in

the region. Possible pollutants for the soils in the designated territory are mainly

industry, transport, plant protection activity (PPA), landfills, and past environmental



damages (at some places not all problems of the pesticide storages are solved in the

municipalities of Momchilgrad and Dzhebel). There are many locations in the

designated area, comprising small farms, which store manure illegally and its

subsequent use is a precondition for diffuse ground and surface water pollution. It is

necessary that animal farms execute the Rules for good agricultural practice

protecting water and soils from contamination with nitrates released by agricultural

sources. Over the past years, a tendency of reducing land and soil pollution has been

observed. Economical use of pesticides and fertilizers in agriculture programmes for

ecological agriculture and stock-breeding, control introduced to limit the emission

pollution related to air, waters and waste management, technological renewal of

production processes are activities leading to reduction of soil degradation. Until now

there is no risk of pollution of water sources for drinking water supply, for watering of

animals, of water bodies and sensitive ecosystems. There is a potential risk of soil

contamination from the illegal waste landfills on the territory serviced by ViK OOD

Kardzhali.

There is registered soil contamination in the village of Shiroko pole, municipality of

Kardzhali with metal ions above the threshold limit value – TLV (Zn-1,69 times above

TLV and Pb-1,19 times above TLV).

Water erosion is increased in the lands of the municipalities of Kardzhali,

Momchilgrad, Krumovgrad, Chernoochene and Kirkovo.

Water 2.2.3.3.

Water resources in the designated territory of VIK OOD-Kardzhali are formed by

surface and groundwater sources.

Surface water

The main water artery within the designated territory is the river of Arda and its

tributaries. There are two major hydro energy facilities and 22 of micro dams for

irrigation built along the river basins.

The designated territory is situated in the catchment area of Arda River. Surface water

is polluted by:

- Point sources of pollution – industrial enterprises, which do not treat the

generated wastewater to meet the necessary requirements, direct discharge

of domestic wastewater from the settlements in the receiving bodies;

- Diffuse sources of pollution – unregulated fertilization of arable land, storing

manure masses from stock-breeding, unregulated storing of hard domestic

waste, waste landfills, which do not meet the legal requirements, using septic

tanks by a significant part of the population due to the lack of sewerage.

Groundwater

The quality of groundwater used for drinking water supply of all water abstraction

facilities comply with regulatory requirements, Groundwater is susceptible to pollution

in urbanization regions . Contribution to the observed negative tendencies also has



the large scale cutting down of trees in the water supply zones and immediately

around the water sources.

* More detailed data about water status and its pollution from domestic and industrial

sources are presented in Chapter 3 - item 3.1, item3.2 and item 3.5.9..

Noise pollution 2.2.3.4.

A significant share in the acoustic mode belongs to the noise generated by the big

industrial enterprises, which are located in remote industrial zones away from the

residential areas of the town of Kardzhali, and measures are taken for silencing the

production and the facilities – “Gorubso-Kardzhali” AD – town of Kardzhali,

“Pnevmatika Serta” AD, “S and B Industrial Minerals” AD, Bentonite and Zeolite plant

in the town of Kardzhal i, “Ustra-Beton” AD – town of Kardzhali. Noise emitters are

mining, transport noise in towns and settlements, located near road areas with heavy

traffic. Noise burden is increased during construction works. When the suggested

measures are implemented the noise burden can be reduced to the legally required

limits.

Waste management 2.2.3.5.

The municipalities in the designated territory have available an approved by the

competent authorities waste management programs. For the sludge of the urban

WWTP of the settlements included in the investment program there are elaborated

sludge management programs and it is necessary to update them regularly by

specifying the possibilities for their utilization.

The Municipalities in Kardzhali District suspended in advance the operation of the old

municipal landfills, closed down under program “Regional Centre for Waste

Management – Kardzhali” (RCWM). Domestic waste is transported to the site of the

old landfill of Kardzhali Municipality until the construction and operation of the first cell

of RCWM Kardzhali. RCWM will treat inert, non-hazardous and hazardous waste

generated on the territory of the Municipalities of: Kardzhali, Momchilgrad, Dzhebel,

Chernoochene, Ardino, Kirkovo, Krumovgrad and Ivaylovgrad (Haskovo District). 4 re-

loading stations will also be constructed on the territory of the municipalities of Ardino,

Kirkovo, Krumovgrad and Ivaylovgrad. Currently on the territory there are no

specialized landfills for construction waste corresponding to the legal requirements.

On the territory there are landfills for industrial and hazardous waste of companies

from the sectors of energy, chemical industry and ferrous metals industry (major part

of it is ash from coal combustion, lead slag and sludge from the treatment of industrial

wastewater). Most of the medical institutions send their hospital waste for preliminary

treatment through microwave disinfection at MBAL “Dr. Atanas Dafovski” Ad – town of

Kardzhali. The biological waste treated in this way is them sent for disposal to the

regional landfill at the village of Vishegrad, Kardzhali District. SPH Kardzhali, MBAL

“DR. S. Rostovtsev” EOOD-town of Momchilgrad and MBAL “Zhivot+” EOOD – town

of Krumovgrad send their hospital waste for treatment through autoclaving at “ML-

Bulgaria” AD. The waste generated from the medical activity of all medical institutions

under code 180202 is transported to the incinerator for hospital waste at

Aleksandrovska Hospital, city of Sofia.



Biodiversity, protected areas and zones 2.2.3.6.

The region of the designated territory of “Water Supply and Sewerage” OOD –

Kardzhali is characterized with significantly rich biodiversity, which is confirmed by the

great number of protected areas and zones. The protected natural zones in the scope

of the designated territory within the borders of the settlements of the municipalities

are: protected areas and protected zones on the territory controlled by RIEW-

Haskovo.

District

According to the Report on applying Directive 91/271/ЕЕС and Order № RD – 970 of

28.07.2003 of the Minister of Environment and Water, the water classified as

“sensitive zone” of water bodies in the designated territory is described in details in

Section 3.1.2.3.

HYDRO-GEOLOGICAL CONDITIONS 2.2.4.

Terrain conditions 2.2.4.1.

The territory of Kardzhali District, serviced by “Water Supply and Sewerage” OOD –

Kardzhali, structurally falls within the Eastern Rhodopes part of the Rhodopes massif.

This is morpho-structural decline of fault-block construction, deeply divided by Arda



River and its tributaries. Upon this big structural unit are developed Madan-

Davidkovsko, Kesebirsko and Belorechko heaves, made of Pre-Cambrian

metamorphites, as well as Momchilgradsko depression, which is viewed as part of the

broad Eastern Rhodopes Paleogene decline, filled with paleogenic continental and

see sediments, andesite and rhyolite volcanic rocks.

The Quaternary formations include alluvial sediments at Arda River and its tributaries

Varbitsa, Krumovitsa, Perperek, etc. (gravels, sands, clays) and delluvial formations of

sandy clays with rock parts on some places, covering the root rocks with sporadic

distribution.

Significant development at the designated territory undergo weathering and erosion-

accumulation, karst and gravity processes and phenomena, defined by geological-

tectonic, hydrological, engineering-geological and other factors.

The weathering processes are presented in the mechanical revealing of petrogenic

and tectonic cracks, development of new disoriented cracks, dismemberment and

disintegration of the massif in the hypergenic zone, and in the chemical transformation

of rock-forming minerals mainly in the scope of the revealed rock complexes in the

Rhodopes.

Erosion-accumulation processes include surface denudation and riverbed erosion. To

a greater level erosion has affected the weaker terrigenous sediments in the open

treeless and grassless areas. A result of the weathering and erosion-accumulation

processes and phenomena is the current geo-morphological view of the region, the

Quaternary, mainly delluvial formations on the slopes, etc.

The karst processes and phenomena are found in the carbonate sediments of the Pre-

Cambrian rocks. Results of these processes are various surface and underground

karst forms – bowls, eddies, hollows, channels, traverses and caves.

The gravity processes and phenomena (landslides, tearing-aways) have broad

development. As per the Map of landslides in the Republic of Bulgaria at a scale of 1 :

500 000 (MRDPW, GI at BAS, 2006) there are many registered stabilized and active

landslides, mainly along the national road network, on the territory of the municipalities

of Ardino, Dzhebel, Kardzhali and Krumovgrad. One of them is a big old landslide

covering an area of a slope west of Borovets residential quarter of the town of

Kardzhali, within the road Kardzhali-Enchets-Blenika-Dazhdovnitsa-Padartsi. Parts of

the landslide are periodically activated. The landslides are mainly of delapsive type,

shallow to deep, with a volume of the fallen earth mass to a million cubic meters.

As per Ordinance № RD-02-20-2/27.01.2012 for the design of buildings and facilities

in earthquake areas:

- the buildings and facilities in the settlements south of Arda River are secured

for level VII with a seismic coefficient Sc= 0,10;

- the buildings and facilities in the settlements north of Arda River are secured

for level VIII with a seismic coefficient Sc = 0,15.

On the territory of the municipalities there are deposits of lead and zinc ores in the

municipalities of Momchilgrad and Ardino, of gold near the town of Krumovgrad and of



chrome ore in the region of the village of Dobromirtsi, municipality of Kirkovo. In the

region of Kardzhali there are significant in size deposits of non-metallic minerals – the

only deposits in the country of bentonite near the town of Kardzhali and of perlite in

the municipality of Dzhebel. Construction and tiling materials are explored – trass in

the municipality of Kardzhali, marble in the region of Ardino and Dzhebel, and

limestone in the municipalities of Kardzhali and Dzhebel.

The engineering-geological conditions on the territory serviced by “Water Supply and

Sewerage” OOD – Kardzhali are defined by the natural resources – landscape,

geological structure, lithological content and physico-chemical properties of the rocks,

the sedimentation conditions, the groundwater in the rock massifs, the physico-

geological processes and phenomena.

Regarding the conditions for executing the construction work (ditches, embankments,

foundation of facilities, etc.) the lithological varieties forming the geological

environment are classified as earth soils, the excavation of which is possible with an

excavator, and as rocky soils, the excavation of which is possible the use of

explosives and / or heavy-duty excavators.

The estimated volume of excavation works in earth and rocky soils is estimated as

follows:

- for the sewerage networks – earth soils about 50 %, rocky soils – 50 %;

- for the water supply networks – earth soils about 70 %, rocky soils – 30 %.

Hydrological conditions 2.2.4.2.

The hydro-geological conditions within the area of Kardzhali District are determined

by karst, crack and pore groundwater. In Appendix 2-3 are presented maps of

groundwater bodies.

Karst water is contained mainly in the marble bodies of Dobrostanska suite and in

other suites from the Pre-Cambrian. Karst water is supplied by rainfall directly through

the outbreaks of the carbonate rocks and through the Paleogene mantle of cracked

rocks. Fragments of groundwater body “Karst water – Ardino-Nedelinski basin” under

code BG3G00000Pt042 fall within the boundaries of the municipalities of Ardino and

Dzhebel. Karst water draining is mainly from springs with changing flow, more

significant of which are: “Byal izvor” and the springs at the towns of Ardino and

Nedelino in the Ardino-Nedelinski basin and others. Karst water is mainly hydro-

calcium with mineralization in the range of 200-500 mg/l. Based on data from the River

Basin Management Plan for East Aegean Sea Region “the groundwater body” is in

“good” chemical status.

Fissure water is formed in Paleogene and Pre-Cambrian rocks. It is a pressureless

body characterised by shallow circulation of groundwater in the hypergenic, cracked

and weathered zone. Fissure water is fed mainly through rainfall. They are drained

through springs with changing flow. Fissure water on the territory serviced by “Water

Supply and Sewerage” OOD – Kardzhali is found in the following groundwater bodies:

“Fissure water in Central Rhodopes complex” under code BG3G00000Pt046, “Fissure

water in East Rhodopes complex” under code BG3G00000Pg028 and “Fissure water



– Krumovgrad-Kirkovska zone” under code BG3G000PtPg023. The chemical content

of fissure water is: hydrocarbonate-sulphate-calcium-magnesium with mineralization of

100-600 mg/l.

Pore water is accumulated in the gravel-sand Paleogene and Neogene sediments

and Quaternary, alluvial and delluvial formations. There is formed groundwater body:

“Pore water in Quaternary – Arda River” under code BG3G000000Q010. Pore water is

fed through precipitation and fissure and karst water. They are drained in the river-

ravine network and through water abstraction facilities. Pore water is mainly

hysrocarbonate-calcium-sodium with average mineralization of 500-600 mg/l.

Besides the described groundwater bodies, on the territory of Kardzhali District are

also situated mineral water deposits “Dzhebel” and “Kirkovo”, which are exclusive

state property.

Chemical status

Assessment of the chemical status of groundwater bodies is generally carried out by

comparing the so-called relevant values and the threshold values of individual

chemical status indicators. If all status indicators are "good", the groundwater body is

identified as being in "good" condition. If one or more status indicators are "poor", the

groundwater body is identified as being in "poor" condition. In such case, this is

followed by a careful hydrogeological analysis of monitoring points, which are crucial

for defining a groundwater body as being in "poor" condition. If these monitoring points

are not considered to characterise a sufficiently representative volume of the

groundwater body, the same are excluded from the general assessment of the

groundwater body status as a whole.

According to data from the River Basin Management Plan of the East Aegean Region

groundwater bodies BG3G00000Pt042, BG3G00000Pt046, BG3G00000Pg028 and

BG3G000000Q010 are in “good” chemical status, while water body BG3G000PtPg023

is in “poor” chemical status, but there is no abstraction from it for domestic-drinking

purposes.

The quality of groundwater bodies under code BG3G00000Pt042, BG3G00000Pt046,

BG3G00000Pg028 BG3G000000Q010 complies with the relevant ordinances and

directives: Ordinance № 9/16.03.2001 on the quality of water intended for drinking

purposes, Ordinance № 1/10.10.2007 on the specific requirements for groundwater

exploration and use and Directive 98/83/EC on the quality of water intended for

human consumption. More details - in item 3.1.

Conclusion 2.2.4.3.

The following groundwater bodies are situated on the territory of Water Supply and

Sewerage OOD – Kardzhali: one karst, three fissure and one pore water body. Karst

and fissure water is fed by infiltration of storm water directly from the surface or from

water from the rivers in the region. Pore water is fed by precipitation, rivers during high

water and by fissure and karst water. Hydrogeological conditions are summarized in

the table below.

HYDROLOGICAL CONDITIONS 2.2.5.

Hydrological conditions on the designated territory of ViK OOD Kardzhali are

determined by orohidrographic and flow features of the river valley of Arda River and

its tributaries within the section of the considered territory. Arda River is the main

surface water source for the region of the designated territory. As a result of its natural

characteristics of the flow it is characterized as water abundant with significant

hydropotential, with big hydrotechnical facilities built on it.

Typical for the hydrological regime of the river and its tributaries is that they are water

abundant and torrential as a result of the combination of continental and

Mediterranean climate influence. Most of the rivers with small catchment areas are

characterized by the two extremes: full drying and sudden big floods during intensive

rainfall. For the south tributaries high waters are in December and February, and low

waters – in July – September. The north tributaries have a smooth maximum in

February – April and smooth minimum in August – September. Along the main river, of

course, there is a mixture of these two conditions, with prevailing participation of the

south tributaries for the lower part of the river valley. From a water-economy

perspective the northern tributaries have a preferable monthly flow distribution.

The runoff module showing the intensity of the drainage formation as an average of

the basin areas along the rivers in the designated territory of ViK OOD Kardzhali

varies within a small range given the similarity of the terrain and small differences in

altitude of the catchment areas of the rivers along Arda River Valley.

There is also visible dependence of the average annual runoff fluctuations on the

altitude and the influence of the Mediterranean climate. Fluctuation and respectively

variation coefficient Cv are lower for the higher catchment areas along the river valley.



2.3. SOCIO-ECONOMIC FEATURES

DEMOGRAPHIC DEVELOPMENT 2.3.1.

The designated territory of “Water Supply and Sewerage” OOD Kardzhali includes

244 settlements of a total of 471 settlements in all 7 municipalities in Kardzhali District.

The territorial structure of population distribution in the designated territory includes 5

urban centres (towns) and 239 villages.

The last Census data indicates that the population serviced by ViK OOD Kardzhali

amounts to 135,274 people or 88.5% of the population in the 7 serviced municipalities.

In the past 10 years, the population in the designated territory has declined by

approximately 4.96 % or 7,099 people. The population decline is little above 2 points

below the average for the country. For the entire period between 2001 and 2011, the

natural population growth rate continued to be negative, with values below the national

average. Statistical data indicates that the decline in the population served is also a

result of the negative migration growth.

The summarized data on the demographic development within the designated territory

is presented in the table below.

Source: http://censusresults.nsi.bg/Census and http://www.nsi.bg/nrnm

As a general tendency, smaller settlements tend to lose population more rapidly in the

last 10 years as compared to the municipal centres. This trend is combined with

deterioration of the age structure and decrease of the fertile contingent.

The main part of the population served by ViK OOD Kardzhali lives outside the urban

centres – nearly 53% (71,907 people) of the entire population. In the last 10 years the

main share of the urban population increased slightly from 46% (2001) to 47% in

2011, which remains significantly below the average level of the country of 72.5% for

2011. In two of the municipalities there are no urban centres and 100% of the

population lives in villages. A total of 6 settlements have population more than 2000

people as of 2011, 5 of which are towns and 1 is a village.

In the period between 2001 and 2011, the demographic development in the

designated territory has followed the national trend towards aging of the population. In

contrast to the country, the aging processes are not so strongly expressed due to the

higher birth rate. The main factors which can have a significant influence in the future

and accelerate the processes are related to reduction of the fertile contingent

compared to higher average age of the mothers at birth, the increasing average life

expectancy and the negative migration flows.

The data from the last Census indicates that young people of age between 0-14 years

amount to 13,9%, which is close to the natural average of 14%. As a result of the

negative demographic processes the reproductive base of the generational pyramid of

the designated territory is slowly shrinking (Figure 2-3).

The share of elderly people is expected to continue growing and reaches up to 16,9%

of the total population. If the current tendency is maintained then after 35-40 years the

age structure of the population will gradually adopt a profile of elongated chimney,

principally different than the current one – with relatively narrow base and a huge

number of elderly population on the top. This is demographic inertia, which can be

hardly influenced in the perspective of 5 – 10 years.

From economic perspective the instantaneous profile of the age structure,

characterized by accumulation of productive population, gives opportunity to use the

so called “demographic dividend”, since the people in working age are about 70% of

the entire population of the designated territory.

The total coefficient of age dependence6 is 44,5%, which is about 3% below the

average for the country. The coefficient of demographic replacement 7 is 0,97, which is

the highest parameter in the country.

The registered trends in the demographic processes in the region will largely

determine the future development of the population determined on the other hand by

the momentum of the demographic processes – the population of the designated

territory of ViK OOD Kardzhali will continue to decline in the short and medium term,

at a rate lower than the average national one. The emigration processes will probably

be influenced by the economic development of the region, described in chapter 5.

ECONOMIC INDICATORS 2.3.2.

The Gross Domestic Product (GDP) of Bulgaria has reached values of BGN 75,265

million in current prices in 2011, which is BGN 4,754 million higher than the value in

2010. However, the analysis of GDP growth in constant prices amounts to BGN

52,833 million in 2011 compared to 2005 when the real growth is 1.67%. These

results outline the slow economic recovery of the country after the first negative

growth of GDP for the last 15 years in 2009. The first signs of overcoming the crisis

appeared in the second-third quarter of 2010, when the real volume of the gross

domestic product of Bulgarian economy started to grow again and reached 1.7 % on a

yearly basis, at the end of 2011. The industrial sector is practically the only one with

substantial growth for 2011, with an increase of 9.1% in Gross Value Added (GVA).

The real increase in GVA for 2011 was very low – 1,81%. Figure 2-4 outlines the trend

in GDP development for the last 11 years.



Source: http://www.nsi.bg/ORPDOCS/GDP_1.1.1.xls

Regional GDP data is collected at NUTS II level and at NUTS III level it is limited and

presented for 2 years behind. The designated territory of ViK OOD Kardzhali falls

within the boundaries of South Central Region, which produces approximately 14% of

the national GDP and has lower economic growth as compared to national

tendencies. These differences are significant and growing with time (GDP per capita in

2010 is about 70% of the average national compared to over 76% in 2000 – the trend

is presented in lines on Figure 2-5) and it may be assumed that while the regional

economic growth follows the national trends, the difference will increase at a lower

rate.


Figure 2-4 GDP growth

Figure 2-5 Comparison between regional and national GDP growth per capita (BGN)



Statistical data for the GDP in Kardzhali Districts indicates economic growth lower not

only than the national but also than the regional one. In 2010 GDP per capita in

Kardzhali District amounts to only 54,2% of the national average and 77% of the

regional GDP per capita. The outlined differences grow with time as shown by the

trend lines of Figure 2-6.


Inflation was relatively high in the past decade (up to 2008) due to the convergence of

price levels from 41% to about 50% of the EU average in 2008. Price rises since 2009

have been more moderate and inflation in Bulgaria for 2010 has been below the euro-

area average, despite the unabated rise in unit labour costs. The annual inflation for

2011, measured by means of the consumer price index is 4.2% compared to 2010.

The increase is largely due to the rapid growth of fuel prices because of the unstable

international environment. The average inflation for the first half of 2012 is below 2%

and the expected all-year inflation is about 3-3.5%. This tendency is expected to

remain stable for the next years and Bulgaria will be one of the EU countries with the

lowest growth rate of consumer prices.

HOUSEHOLDS CHARACTERISTICS 2.3.3.

The number of households on a national level has increased despite the negative

trend in population development in the last years. For the years between the two

population Censuses, the households in Bulgaria have increased by 2.8%. This

situation points out a rapid decline in the “people per household” indicator, which falls

in 2011 to 2.4 people from 2.7 people. At Kardzhali District level the similar tendency

is observed and the “people per household” indicator changes from 3,1 people to 2,8

people in 2011.

Household income on a national level has increased steadily in nominal terms for the

past 10 years. Only 2010 makes an exception to the outlined trend, with registered

decrease of 1,2%. Real household income for 2010 has declined by 3.6% compared

to 2009, taking into account the influence of inflation. Regardless of the real income

growth over the last 10 years, the incomes in 2010 are lower compared to the real

incomes in 2007 and 2008.

In the last years leading role for wage increase had the private sector, while the wages

in the public sector grew slower. Freezing the wages and pensions since 2010 helped

diminishing the pressure for increasing the wages.

Labour remunerations and pensions are the main income sources for Bulgarian

households and their relative shares have changed significantly over the past years.

The observed processes of population ageing lead to significant increase in the

relative share of pensions in the total household income, compared to the incomes

from salaries, which are characterised by lower growth. At the same time, incomes

from own agricultural production constantly lose their significance and their share in

the general structure of the income decreases dramatically from 15% (2001) to 1.7%

in 2011.

Over the past 12 years, the nominal wage income has been largely following the

changes in the total household income. In 2011, the average wage income is BGN

1,960 per capita, growing more than three times compared to 2001 and increasing by

5.5% compared to 2010 %.The real income index of wages increases by 1.3% in 2011

compared to 2010. This index has its highest value in 2011 compared to 2001 -

79.5%, but is less than 100% compared to 2008 and 2009.The relative share of wages

in the total income is 51.8%, and in the beginning of the period it is equal to 38.9%, or

increasing by 12.9 percentage points. It increases by 0.9 percentage points compared



to 2010. In 2011, the amount of social transfers paid (compensations, pensions,

benefits and family allowances) increases more than three times in nominal terms

compared to 2000, and their relative share in the total income grows by 8.8

percentage points. In this position of household income, pensions are dominant. In

2000, income from pensions is BGN 337 and increases in nominal terms to reach an

average of BGN 1,140 per capita in 2011, or more than three times. The income from

pensions also increases in nominal terms from an average of BGN 1,128 in 2011 to

BGN 1,140 in 2010 per person in household, or by 1.1%, while as a relative share in

the total income it decreases from 30.9 % to 30.1%, or by 0.8 percentage points.

The observed processes of population ageing lead to significant increase in the

relative share of pensions in the total household income, compared to the incomes

from salaries, which are characterised by lower growth. At the same time, incomes

from own agricultural production constantly lose their significance and their share in

the general structure of the income decreases dramatically from 15% (2001) to 1.7%

in 2011.

At regional level, the population income structure in Kardzhali District is relatively

similar to the national-level trends. Generally, the District has the most rapidly growing

income per capita in the period 2001 – 2011, which is due mainly to the low base at

the beginning of the period, when the District was occupying one of the last places in

the country. The major part is formed by salaries and pensions. However, some

differences are observed in terms of to their distribution – the share of the salaries is

lower, while the share of pensions is higher than the national average by nearly 1,3%.

There are two key factors - lower level of salaries and deteriorated age structure (a

larger share of elderly population over working age).

The degree of differentiation of population income is based on the indicator "total

income per capita" and ten decile groups. Data related to the total income shows

higher level of vulnerability of the low income groups, where the decrease of the total

income is most substantial under conditions of crisis – by - 5.2% for the income of

decile 1 and by -3.15% from the total income of the first three decile groups. Before

the economic crisis from 2008-2009, an increase in the relative share of the poor

groups’ income was observed in contrast to the one concentrated in the households of

the medium decile groups. The decile groups with the highest income managed to

keep their position over the entire period considered, and in times of crisis, the

reduction of income for these groups is between 0.47% -1%.



Figure 2-8 Total household income by decile groups

Source: NSI

Based on the dynamics of the income in the period 2000-2010 and the impact of the

economic and social changes on their distribution, it may be concluded that groups

with low income seem to be the least protected from the economic and social shocks.

They also include the most risky households in terms of falling into poverty and social

exclusion.

The incomes of the medium and the lowest income groups are falling seriously behind

those of the highest income groups. The income share concentrated in the highest

income groups has remained the same within the whole period. Vertical redistribution

with slightly outlined effect has been observed from the medium income groups to the

lowest income groups. This clearly indicated differentiation in incomes causes

differentiation in consumption, which is a sign of change in the consumption structure

as well as in the level of the living standard.

Generally, household expenditures follow the tendency of income changes during the

last 10 years. Consumer expenditures within the total household expenditures have

not changed considerably within the observed period and are about 85-86% of the

total expenditures. The share of expenditures on housing, water, electricity and fuels

has increased from 12.1% in 2001 to 14.1% in 2011, mainly due to the sharp rise in

the international fuels prices, which exerted serious pressure on the expenses of the

households. Nevertheless, the increase of these expenditures is not larger than the

other categories.

The poverty line in Kardzhali District is 69,04% and is considerably below the national

average8. Taking into account the sources and the structure of incomes and

expenditures (large share of expenditures for food and similar goods) can be

explained with the presence of a relatively large share of agricultural subsistence.

EMPLOYMENT AND UNEMPLOYMENT RATES 2.3.4.

At national level, the labour market was severely affected by the crisis. Bulgaria

registered one of the strongest declines in employment in the EU, which between

2009 and 2011 has declined cumulatively by nearly 9%. National unemployment rate

was 10.9 % in 2011, which is the highest level for the last 5 years.

At regional level, the tendencies in the labour market are similar. The lowest

unemployment rates are registered in 2008. As a result of the crisis the unemployment

rate shows a steady trend of growth. The unemployment rate at district level is above

the national average, being lower than the average for the country only in 2009. After

2009, a strong upward trend in unemployment is observed in the district, which is

characterized by more rapid rates than the national average.

YM=2011/12, Regional Employment Service Directorate Haskovo

Along with the general upward trend in unemployment in the period between 2008 and

2010, the number of persons with duration of their registration as unemployed for over

a year tends to increase slightly. Nearly ¾ of the persons are registered as

unemployed over a year. In terms of age, an increase in the share of long-term

unemployed persons over 50 years of age is observed. The lack of opportunities for

professional realization forces the young people to look for job outside the territory of

the District, which explains the relatively high levels of negative migration balance. A

significant part of the registered unemployed young people does not have the right to

receive unemployment benefits.

Employment in the district is one of the lowest in the country, and as a result of the

crises it shrunk to below 40% employed (among people aged 15 and more). In

Kardzhali Municipality are employed about two thirds of all employed and hired people

in the district.

A leading role regarding employment plays the processing industry and the

construction sector.

DENSITY AND TYPE OF HOUSING 2.3.5.

Population density in the designated territory of ViK OOD Kardzhali is 47,62

people/km2, which is significantly below the average for Bulgaria of 66,4 people per

km2. There are significant differences per municipality. Considerably above the

average is the population density in Kardzhali Municipality – 117,3 people/km2. in the

other municipalities the density is between 21-47 people/km2, which is a result of the

settlements distribution, determined by the terrain features.

The characteristics of the designated territory determine the type of housing. In terms

of construction, massive housing is predominant – over 97% of the total housing

stock. Residential houses make up slightly above 66% of the total number of

dwellings, and the average useful area of a dwelling is 83 m2. Most of the one-

bedroom and two-bedroom residences are located in larger urban centres, while in

rural areas houses with more rooms are predominant. This is determined by the fact

that in most cases more than one generation occupy a single residence.

ECONOMIC DEVELOPMENT IN THE AREA 2.3.6.

In Kardzhali District, the GDP per capita is relatively below the national average.

Employment in the district is one of the lowest in the country, and as a result of the

crises it shrunk to below 40% employed (among people aged 15 and more). In the last

years there is a certain growth of the number of enterprises per capita. There is a

certain interrelation of the economic realities in the region with the political processes.

Direct foreign investments are relatively few.

Net sales income in the district increased by almost 47% in the period 2005-2010 and

reached BGN 884,722 thousand. Leading branch in Kardzhali District is the

processing industry, which forms about 40% of the net sales income. Specific for the

region is the role of the mining industry due to the available deposits of perlite,

bentonite and natural zeolite (90% of the production of which is used in construction,

cement industry and agriculture).

In the agriculture, forest and fisheries sector of paramount significance is tobacco. The

favourable geographic and climate conditions, fragmentation of land in mountain

region, tradition, accumulated experience and family tradition, low land availability,

and the available material base are a prerequisite for the development of monoculture,

in the case it is tobacco and vegetable production.

Kardzhali Municipality has the leading role in the designated territory based on main

economic indicators. Every three out of five enterprises in the district are located on

the territory of the municipality (60%). Almost two thirds of the employed and hired

people in Kardzhali District work in the municipal enterprises and structures. The

prevailing part of the production made in the district in 2010 is realized in the municipal

enterprises (81%). Almost 80% of the realized income in the local economy is also on

the territory of the municipality. The predominant part of the costs for fixed assets are

also determined by the municipal economy (84%). Two thirds of the costs for

remuneration are also in the municipal enterprises and structures.

The slower economic development in the region and the higher unemployment level

additionally contribute to population reduction and especially for the higher out-

migration. Economy development in the designated territory as a whole follows the

growth rate of the national one but is below the average for each of the most important

economic and social parameters – demographic growth, net sales revenue growth,

household income and unemployment.



For the period 2001-2011 the number of students in Kardzhali District decreased by

more than 30%. This leads to decrease in the number of schools from 129 in 2001 to

82 in 2011, as well as to a serious fall down in the number of teachers. Such

processes follow the tendency for the country. Yet, Kardzhali District is characterized

by relatively more teachers per every 1000 students. Those who left the educational

system are less than 2% from all students in 2011, which is the best figure for

Kardzhali in the past 10 years and is relatively better than the average for the country.

There are no universities in the district, but there are branches of the Mining and

Geology University and of Plovdiv University, located in the town of Kardzhali. These

two educational institutions attract students from the neighbouring districts as well,

which is beneficial for the district centre. Nevertheless, Kardzhali is the district with the

lowest percent of university graduates – only 10% of the population aged 25-64 has

higher education, while the average for the country is double. This explains to some

extent the economic problems in the district, as well as the lack of qualified staff.

The ill people who passed through the medical institutions in Kardzhali are traditionally

low – 178 of every 1000 people from the population in 2011. The doctors in the

district, divided per inhabitants, are much lower than the average for the country and

this unfavourable ratio is valid both for general practitioners and for cardiologists.

MAJOR EMPLOYERS IN THE AREA 2.3.7.

Over 97% of the active enterprises in the designated area are micro, small and

medium enterprises. The district is rich in mineral resources and has traditions in the

processing and mining industry. The deposits of mineral resources turn the district into

a raw basis for the development of ferrous metallurgy, logging, processing of non-

metalliferous minerals. Textile, clothing and food industries and machine building are

also developed. There are good traditions for growing oriental tobacco in the district.

The biggest enterprises in the mining industry are: “Gorubso-Kardzhali” AD, which

exploits deposits of lead and zinc, gold and chrome ore in four deposits on the district

territory. Among the biggest companies for extracting non-metalliferous minerals is the

company “S and B Industrial Minerals (Bentonite)” AD – Kardzhali.

In the metallurgy, machine building and metal processing sector the highest number of

staff employs “OTsK-Kardzhali” AD, “Pnevmatika Serta” (hydraulic and pneumatic

cylinders), “Myunek-yug” (mining and metallurgy equipment), “Teklas-Bulgaria” for

automobile parts production, “Hraninvest-HMK” and “Promash” for the production of

automated lines for bread, etc.

Details on the industrial enterprises and their water consumption are presented in

Chapter 2.3.8.

COMMERCIAL AND INDUSTRIAL ACTIVITIES 2.3.8.

The largest water consumers within the boundaries of the service area include

industrial enterprises operating in various economic sectors. According to the data



provided by ViK OOD Kardzhali, their water consumption reaches up to 271,061

m³/year for 2011.

URBAN DEVELOPMENT PLANNING 2.3.9.

The settlement network in Kardzhali District includes 471 settlements of which 5 are

towns. The spatial structure of the settlement network follows the logic of the farmland

fragmentation.

Administrative centre of the district is the town of Kardzhali, where the administrative

structures of the central authority are concentrated. The rest of the district can be

defined as highly “stripped out” of such concentration. Actually, except the district

town, there is no other significant urbanized centre in the district of equal economic,

social or cultural significance. The concentration of activities entirely in the district

centre forms a structure of the centre- periphery type.



The villages are small, and a significant part of them have population less than 200

people. The type of their structure is mainly disperse. The main structural element is

the meridian urbanization line Ruse – Makaza and the parallel border axis.

At the second level as potential for economic development is Momchilgrad, which is

oriented towards the development of separate sectors of industry related to the local

resources. Due to the proximity between Kardzhali and Momchilgrad in the last years

they have been formed as the main urbanization axis on the district territory.

The towns of Krumovgrad, Ardino and Dzhebel are small urban centres, which are an

important element for activating the territory. They have a significant structural

importance regarding the interrelations between the numerous small settlements and

growth centres. Currently the towns are of “transitional type” between the industrial

and peripheral zones.

Local significance for the development have the municipal centres Chernoochene and

Kirkovo, whose functions are similar in mid-term perspective with those of the small

urban centres.

In the following years, a key moment in the planning of urban development is the

process of Integrated Urban Recovery and Development Planning (IURDP), which will

help identify the complex projects to be financed by the Structural and Cohesion funds

of EU in the programming period from 2014 to 2020. In the designated territory only

the towns of Kardzhali and Krumovgrad will be assisted for developing IURDP.

LAND USE AND OWNERSHIP 2.3.10.

The right of land ownership includes the right to possess, use and dispose of the land.

For the purpose of water projects the municipality shall own the land where the

facilities are located or shall be granted a servitude right, which is a special type of

limited real right over the land owned by another.

Servitude rights in connection with water projects are settled in Chapter 7 of the Water

Act (Art. 103-115). The servitude established by law shall have as a subject thereof

public or private benefit. Land servitudes established for public benefit shall refer to

ensuring access to water bodies – public property for common use, for construction of

the infrastructure necessary for that purpose, as well as for maintenance of water

systems and facilities designated for provision of the services of water supply for the

population and for irrigation. Land servitudes for a private benefit arise in connection

with the location of the land and the right to pass and conduct water across the land. A

change in the land ownership does not terminate the effect of the servitude.

Each land owner shall be obliged to grant the right to conduct water across his

property to all who have permanent or temporary need to do so. If it is necessary to

construct pipelines or facilities for transferring water, servitude strips shall be

determined with a size not bigger than the diameter of the pipeline, increased with 60

cm, where construction or perennial planting shall not be permitted. The right to

conduct water across another's property shall be established with an agreement of the

owners of the dominant property and of the subservient property and if such an

agreement cannot be reached - with an act of the body under Art. 52, paragraph 1,



item 4 of the Water Act, observing the procedure of Art. 34 and 36, without ruling the

alienation of the property concerned.

The implementation of investment projects in the water sector may require the

purchase of additional undeveloped land and a change in the purpose of use of land.

The change of the purpose of use of agricultural land for non-agricultural needs is

permissible for:

• Construction of elements of technical infrastructure under the Spatial Planning

Act;

• Creation or expansion of building boundaries of existing urbanized territories

(settlements and settlement formations);

• Creation or expansion of the boundaries of separate regulated land plots

outside the building limits of existing urban territories (settlements and

settlement formations).

WATERBORNE HEALTH PROBLEMS 2.3.11.

In the Republic of Bulgaria, the competent authority in the field of drinking water is the

Ministry of Health and its regional structures according to the Water Act and the

Health Act. The water supply organizations, in their capacity of structures, carrying out

water supply activity for drinking-domestic purposes, are responsible for the fulfilment

of the legislation requirements for drinking water, including drinking water quality

monitoring in its full volume. In the designated territory of Water Supply and Sewerage

OOD – Kardzhali constant monitoring of drinking water in separate stations according

to an approved schedule which is updated each year and periodical monitoring are

being performed.

According to the effective legislation, state health control of drinking water is

performed by the Ministry of Health, respectively RHI in the following major directions:

- Drinking water quality monitoring in all settlements of the country is carried out

by taking samples as well as by conducting laboratory analysis: of raw water

from the water sources for drinking-domestic water supply, at the “end

consumer”, of water at different stages of its treatment, of water delivery to the

“end consumer”, water from independently supplied sites, water from

“independently supplied sites”.

- RHIs are obliged to carry out at least 50% of the full volume of investigations,

which need to be executed by the WSSC.

- RHI exercises control over the sanitary protection zone of the sites and

facilities intended for central drinking-domestic water supply: water sources,

water abstraction facilities, sanitary protection zones (SPZ), drinking water

treatment plants (DWTP), disinfection installations – chlorination and other

stations for water disinfection, reservoirs, independently supplied sites,

bathing zones, etc.

The water supplied to consumers in the designated territory serviced by ViK OOD-

Kardzhali has good quality and is suitable for drinking and household purposes. There



are no infectious or other diseases registered in the last years due to the use of

drinking water. Part of the problems is due to failures of the treatment facilities, of

parts of the sewerage network, reasons related to the water abstraction facilities, etc.

During the monitoring of the physico-chemical and microbiological indicators in

drinking water in the period of 2008 – 2012 an annual level of standard compliance

percentage ranging within 99,02% – 99.77% is achieved for all parameters, i.e. less

than 1% deviation. A table including data of the permanent monitoring conducted

(covering only part of the observed parameters) and periodic monitoring is given in

Appendix 2-4.Control over the water quality is exercised pursuant to Ordinance №9

/16.03.2001 on the quality of water for drinking and household purposes (SG No. 30 /

2001). With the available equipment of the company chemical laboratory permanent

and regular monitoring can be carried out only for half of the monitored physico-

chemical and other parameters, but for all microbiological parameters (the remaining

chemical and radiological indicators are assigned to external laboratories). Envisaged

is the full testing of the more significant water sources with capacity of more than

14000 m3 overnight: for Borovitsa Dam and for zones above 3000 m3/day –

Krumovitsa zone and Varbitsa zone. For more data – see Appendix 3-3 and Appendix

3-4.

In the Permanent Monitoring (PM) carried out in the period 2008-2012 (only part of the

monitored parameters are covered) and in the Periodic Monitoring (PRM) deviations of

single indicators were found not compliant with the requirements of Ordinance №9

/16.03.2001 on the quality of water for drinking and household purposes. The

registered deviations should be eliminated in the shortest possible term by envisaging

the respective efficient measures.

Physico-chemical indicators -

Deviations from the requirements of Ordinance No 9 /16.03.2001 have been

registered (mainly deviations in the parameter turbidity and rarely for рН).

Higher content of residual chlorine - overdosing chlorine for water disinfection during

not well controlled work of the disinfection installations and their management control

management.

Reference of the monitoring carried out for 2008-2012 – in Appendix 2-4.



Discrepancies in microbiological parameters – The registered deviations are below 1%

(there is a tendency to minimize the deviations from the legal requirements). The

problem is of leading health importance (as per recommendations of the World Health

Organization non-standard annual values of the health important microbiological

parameters must not exceed 5%) and creates a direct risk to the consumers’ health. It

is expected to occur in emergency breakdown situations, in cases of insufficient

disinfection, etc. Main reasons are: lack of treatment or obsolete, inefficient existing

wastewater treatment facilities.

CONCLUSION AND RECOMMENDATIONS 2.3.12.

The service area of Water Supply and Sewerage OOD – Kardzhali can be

characterized as both urban and rural with approximately half of the population living

in large number of smaller settlements. The resulting low population density and the

negative demographic development will exert significant influence on future

investments in water and wastewater networks, keeping in mind the constant trend

towards urbanization. In addition, smaller settlements are likely to lose population

more rapidly than larger towns in the designated territory. Some of the settlements

with population of over 2,000 people in 2011 will most likely have less than 2,000

people in the next 10 to 15 years. However, population will decrease slower than

observed in the 10-year historical period.

Economy in the designated territory is growing with lower than the national rate for the

last 10 years. This tendency is about to continue and regional and national disparities

will get bigger unless both national and local measures are taken. These include

improvement of existing infrastructure, incentives for investors, etc…The process of

urbanization will result in the need of more employment opportunities and higher

monetary income of households that will no longer rely on subsistence farming. On

the other hand the reduction of the population in the smaller settlements causes

serious issues related to the future economic efficiency at the realization of investment

projects.

2.4. WSS SERVICES

WSS OPERATORS 2.4.1.

Water Supply and Sewerage OOD – Kardzhali is registered with Decision № 176 of

05.09.1991 of the Kardzhali District Court with main activities maintenance and

exploitation of water supply and sewerage systems, water supply dams, treatment

plants and internal settlement water supply and sewerage systems. On 02.07.1997

the company is re-registered from EOOD to ViK OOD Kardzhali. The company

performs its business pursuant to the Water Supply and Sewerage Services

Regulation Act. Allocation of the company capital is in partnership as follows:

• 51% State participation represented by MRDPW Sofia

• 18% Kardzhali Municipality



• 8% Krumovgrad Municipality

• 8% Kirkovo Municipality

• 5% Momchilgrad Municipality

• 4% Ardino Municipality

• 3% Dzhebel Municipality

• 3% Chernoochene Municipality

Principal’s functions of the state participation are carried out by the Minister of

Regional Development and Public Works.

The overall financial status of the company is good. In the last financial years it had

minimum profit. For its investment activity the company used a loan from the World

Bank amounting to USD 1600000 with maturity up to 2011. Due to the low return rate

of water price, the company has difficulties paying it off. The company has positive but

very low profitability. It does not allow the company to self-finance its development and

limits the possibilities for using the attracted funding.

The total capital of the company amounts to EUR 161,600.2 (BGN 316,090). In 2011,

the turnover amounts to EUR 3,658,040 (BGN 7,154,396) and the net revenue is

equal to EUR 3,325,337 (BGN 6,503,694).

“Water Supply and Sewerage” OOD Kardzhali provides water supply and sewerage

services in 244 settlements on the territory of the municipalities of Ardino, Dzhebel,

Kirkovo, Krumovgrad, Kardzhali, Momchilgrad and Chernoochene.

“Water Supply and Sewerage” OOD Kardzhali organization has a well-functioning

structure compliant with the external and internal requirements to the company and

services delivered.

Organizational structure

The organizational structure of “Water Supply and Sewerage” OOD Kardzhali is with

technical/engineering direction and of highly production nature.

The operational activities are routine, the processes are highly standardized. The

machines and part of the equipment have been installed several decades ago, due to

which the main part of the activity aims at system maintenance and repairs.

Staff

The structure of the work based mainly on the organizational structure influences

significantly the employees, their satisfaction and efficiency in the implementation of

tasks. The policy in the sphere of professional qualification and re-qualification is

hampered by the lack of educational unit in the area, which offers and conducts

appropriate vocational training. Attracting qualified water and sanitation engineers is a

serious problem due to the long distance between Kardzhali and the university centre

Sofia. However considering the positive trends in urban development part of these

problems are expected to be solved in the near future.

The information about the staff of “Water Supply and Sewerage” OOD Kardzhali is

summarized in the tables below:

WATER SERVICES AND TARIFF POLICY 2.4.2.

ViK OOD Kardzhali mainly provides services related to water supply and wastewater

collection. The water company is a local monopolist in this sector with no other

competitors in the water supply to the business, administration and population, as well

as in wastewater collection. The services are provided 24 hours a day, seven days a

week i.e. continuously.

The water operator has the right to determine the price level in compliance with the

Water Supply and Sewerage Services Regulation Act, the Ordinance for the price

formation of water supply and sewerage services as well as the Methodological

guidelines for preparation of water operators business plans, published by the

SEWRC.

The state regulation of activities in the water supply and sewerage services is

performed by the SEWRC. It is responsible for monitoring the implementation of the

quality of the service provided by the water operators and used in their business

plans.

The business plan of each water operator clearly describes all parameters required by

the SEWRC for determining the prices using a specific methodology for assessing the

expedience and legal compliance of the prices suggested by the operator.

Detailed instructions for regulation of water and sewerage services prices by applying

the upper price limit method is described in the following document:

http://www.dker.bg/files/DOWNLOAD/direct_vik5.

The prices of WSS services, provided by ViK OOD Kardzhali, which are approved by

SEWRC and are made effective as of 28.02.2013 are presented in the table below:

CENTRALISED HEATING SERVICES SUPPLY 2.4.3.

On the territory of Kardzhali District, no centralized heating services are provided.

PRIVATE WSS OPERATORS IN THE AREA 2.4.4.

There are no private WSS Operators on the territory of Kardzhali District.


The prices of WSS services are determined by the State Energy and Water

Regulation Commission. They reflect the network maintenance costs, the treatment

and water supply costs as well as the investment costs. If the need for investments is

big this will also affect the prices of WSS services. It is up to the municipality and the

operator to determine the level of investments in order to ensure the reducing of

losses and the quality of the services. Compared to other European countries the

price of water in Bulgaria is lower. In Germany for example through the years large

investments have been made in network renewal and as a result the percentage of

losses in the network is very low, but at the same time the prices of water are very

high. It is a matter of political decision and choice of policy. If Bulgaria decides to have

a higher price this would allow for investing more in the network, reducing losses,

treating more waste water, since in many cities in Bulgaria this is not done. But all this

requires investments. They can come from the European Union too, but part of them

must probably be provided from the price of WSS services.

The prices of WSS services on the territory of “Water Supply and Sewerage” OOD -

Kardzhali are below the average for the country. Based on data provided by the

National Institute of Statistics (NIS) for the social affordability of the WSS services

tariffs by regions and districts for 2011, the average for: Kardzhali District is 3,39

BGN/m3, and for the country – 4,43 BGN/m3, and for the South Central Region – 4,17

BGN/m3. Investments must be directed with a priority to the supply of quality water to

consumers, the reduction of losses and the increasing of energy efficiency in the water

supply sector and the increasing of the population connection rate to the sewerage

systems and the WWTP in the sewerage and waste water treatment sect



3. ASSESSMENT OF THE EXISTING SITUATION AND NEEDS FOR

WATER SUPPLY AND SEWERAGE SYSTEMS

3.1. WATER RESOURCES

Surface water quantity and quality in the designated territory of Kardzhali makes it

suitable for domestic-drinking water supply and therefore there is one surface water

abstraction facility on the Kosma dere River and one dam – Borovitsa, for domestic-

drinking water supply constructed in the designated territory.

Groundwater

The settlements on the territory of Kardzhali District use part of the water resources of

groundwater in the groundwater bodies “Karst water – Ardino-Nedelinski basin” under

code BG3G00000Pt042, “Fissure water in the Central Rhodopes complex” under code

BG3G00000Pt046, “Fissure water in the East Rhodopes complex” under code

BG3G00000Pg028 and “Pore water in Quarternary – Arda River” under code

BG3G000000Q010.



The area, resources and permitted annual water abstraction volume from the said

groundwater bodies is shown on a regional level in the following table, based on data

The total maximum flow of all surface water sources is Qavailable = 802,45 l/s , ,

Qyear=10,237.96.103m3.

Variations of surface water flows – monthly and ann ual for 2011

The characteristics of the natural annual flow by water quantities and in water volumes

by HMS, located within the designated territory of Kardzhali are given in Appendix 3-1.



The assessment of the river flow distribution throughout the year indicates that the

run-off modulus, reflecting the average flow formation intensity in the catchment areas

of the rivers on the designated territory of ViK Kardzhali changes within the range of

13.98 – 17.723 l/s/km2 at the respective HMSs, i.e. relatively small territorial

differences due to the uniform topography and the insignificant variations in altitudes

of the separate catchment areas of the rivers along Arda River basin and the

significantly lower values for the basin of Harmanliiska River.

The minimum annual flow has values of 2.827 m3/s for Krumovitsa River to 26.31 m3/s

for Arda River. Compared to the basin area the annual minimum flow varies

significantly.

Table 3-6 presents the internal annual distributions by months in percent for typical

points along the main rivers in the designated territory of Kardzhali.

In Appendix 3-1 (tables 2 and 3) is presented a summarized evaluation of the

territorial and temporal variation of the river flow by months and years for the entire

basin, separately for the annual flow and its internal annual distribution.

Common for the hydrological regime of all Arda River springs is that they are more

water abundant. Most of the rivers with small catchment areas are characterized by

the two extremities: total dry up and sudden big floods during intensive rainfall.

There is also significant unevenness of the summarized annual flows, which during

dry years fall down to 30% of the annual average, and during water abundant years

raise to 300% above it. This torrential character is transferred to the main river –

Arda, as well. The calculations presented in Table 3-6 of the percent distribution of

the flow by months in percent for typical points along the main rivers in the

designated territory of Kardzhali show that along the basin of Arda River the

combination of Continental and Mediterranean climate impact, forming the internal

annual distribution of precipitation, the evaporation potential and the accumulation of

water in the snow cover form the differences among the various catchment areas. It

is visible that for the southern tributaries high water, with share of 17 – 22%, is in

December and February, and low water, with share below 0,4 – 0,8%, is in July –

September. The northern tributaries have a smooth maximum in February – April, with

a share of 10 – 15%, which is governed mainly by precipitation, whose regime is



almost equal to that of the flow, and a smooth minimum in August – September, with a

share of 1.7 – 3.2%, as a result of precipitation decline. Naturally, along the main river

there is a combination of these two conditions with a prevailing participation of the

southern tributaries for the lower part of the valley. From water economic point of view

the northern tributaries have better monthly distribution of the flow.

The hydrological regime of Varbitsa River at the town of Dzhebel and of Krumovitsa

River at the town of Krumovgrad is characterized by two peaks. The primary peak is in

January-February and the secondary – in October-November. Usually there is one

minimum which starts from May till the end of September, as a result of precipitation

decline, which is mainly in August. The spring maximum is almost during the winter

season, which proves that freshets are resulting from rainfall and there is almost no

feeding through snow melting. In the beginning of October as a result of the rainfall,

there is an increase in the flow and the autumn maximum occurs.

The general hydrological regime typical for the south-eastern tributaries along Maritsa

River (in this case Harmanliiska River) is that, the left tributaries are less water

abundant due to the less rainfall and lower altitude. The freshet maximum for them is

in February and the minimum of low waters – in August-September.

The flow of Byala River is formed under the influence of the Mediterranean climate

and varies significantly. The flow variation coefficient at the village of Dolno Lukovo is

very high – 0.616, as is the asymmetry coefficient – 1.785. The run-off module is 11.7

l/s per sq. km as a result of the insignificant altitude. During the maximum flow

(February) Byala River turns into a big river, washes away bridges, forms broad

meanders. Typical for the monthly minimum flow is that it is almost or equal to zero for

Byala River at the village of Dolno Lukovo. This peculiarity is typical for catchment

areas under Mediterranean climate influence, typical for which is the unfavourable

inter annual distribution of precipitation.

Surface water quality 3.1.2.3.

The surface water in the region of the designated territory are used for drinking water

supply, water for technical needs, for irrigation, for recreation and the water bodies

receive the industrial and domestic wastewater of the region.

Surface water quality used for certain purposes should be consistent with the

requirements.

Condition of the surface water resources for drinki ng and household water

supply.

The assessment of the surface water bodies’ condition is carried out depending on the

category of the water sources in them. The water sources category is determined

based on the results of the monitoring carried out and the standards in Annex 1 to

Ordinance No 12/2002 on the assessment of the condition of surface water for

drinking and household purposes. Pursuant to this ordinance water sources are

classified in three categories depending on water quality – A1, A2, A3, A1 being the

best quality water. On the territory of Kardzhali district there are 2 surface water

catchments for drinking and household water supply in the Arda basin – Borovitsa



dam and Kosma dere River. In addition another water body has been defined on the

Kazatsite River. A procedure for issuing a drinking and household water supply

permission has been initiated. In Table 3-7 are presented the defined water sources

categories and surface water bodies condition according to data from the 2012

monitoring.

The two water catchments are category A2 and A3 pursuant to Annex to Ordinance

12 which determines the good condition of the water bodies, i.e. they are suitable for

drinking purposes.

Surface water bodies condition – the water bodies receiving wastewater (with

discharge permission issued by the EASRBMD) must comply with the regulatory

requirements in force. Surface water polluted above the permissible levels creates

health risk conditions to the population in the region. Constant and periodic monitoring

is performed for assessing the water quality in certain points in the water bodies. Based on data from the monitoring is assessed the water body pollution from

wastewater discharges as point-source pollutants. Currently the water bodies are

polluted mainly from untreated domestic and industrial wastewater.

On the territory most typical are National Automated Environmental Monitoring System

points of RIEW-Haskovo, which represent the impact upon the waters of Arda River

and its tributaries. Appendix 3-5 contains more detailed information for the condition of

the surface water bodies.

Specific sensitive zones in the basin of the Arda River:

- the Arda from the springs to the village of Arda;

- the Arda after the village or Arda to the town of Kardzhali;

- Borovitsa dam – sensitive zone;

- Kardzhali dam – sensitive zone;

- the Arda River after the town of Kardzhali to the border;

- Studen Kladenets dam after the joining of Cherna River to the joining of

Krumovitsa River;



- the Varbitsa River after the village of Benkovski until it flows into Studen

Kladenets dam.

Wastewater from all agglomerations, which are in “sensitive zone” according to

the application of the requirements of Directive 91/271/ЕЕС concerning urban

wastewater treatment for agglomerations of over 10,000 P.E. and agglomerations

of 2,000 to 10,000 P.E., i.e. wastewater from the agglomerations of Kardzhali,

Momchilgrad, Ardino, Dzhebel and Benkovski need to be treated for removal of

the biogenic elements of nitrogen and phosphorus to meet the increased

Groundwater quality 3.1.3.3.

The quality of the groundwater, used for domestic-drinking water supply, from all water

abstraction facilities is compliant with Ordinance № 9/16.03.2001 on the quality of

water, intended for drinking water purposes and with the Quality Standard specified in

Ordinance № 1/10.10.2007 on the study, use and protection of groundwater and

Directive 98/83/EC/.

Water quality protection is ensured by establishing sanitary protection zones in three

belts, the boundaries of which are determined under Ordinance № 3/16.10.2000 on

the terms and conditions for investigation, design, approval and operation of sanitary

protection zones around water sources and facilities for drinking water supply as well

as around mineral water sources used for medicinal, preventive, drinking and hygienic

purposes. The quality of groundwater used for domestic-drinking water supply from all

water abstraction facilities is compliant with Ordinance №9/16.03.2001 on the quality



of water, intended for drinking water purposes and with the Quality Standard specified

in Ordinance № 1/10.10.2007 on the study, use and protection of groundwater and

Directive 98/83/EC/.

Issuing water use permissions, establishing SPZs in three belts around the water

sources and obeying the usage mode on the territory of the respective belt is of

primary importance for protecting water quality.

WATER RIGHTS AND OVERALL UTILISATION OF RESOURCES 3.1.4.

Water rights 3.1.4.1.

The main principle with regard to ownership of natural resources on the territory of the

Republic of Bulgaria is that they are state property. This principle is also applicable to

the property right of waters and water bodies. Public state properties are the river

waters as well as waters in reservoirs including waters in dams and micro-dams,



natural lakes and groundwater. Public state properties are also complex and sizeable

dams as listed in Annex № 1 under Art.13, para.1 of the Water Act.

Waters and water sites, which do not constitute state property, are public municipal

property. Such are the waters and water sites, i.e. natural springs, lakes and swamps,

where located on land constituting municipal property, including mineral waters, dams

and micro-dams.

Private ownership of waters and water sites is also possible, but only of the ones

issuing from within the boundaries of the private real estates and lakes, which are not

fed by waters of public state or public municipal property.

The groundwater, under Art. 11, item 3 of the Water Act, is public state property .

Groundwater abstraction is to be carried out on the basis of the water abstraction

permits issued by the Basin Directorate for Water Management in East Aegean Sea

Region with headquarters in the town of Plovdiv. For further details on water

abstraction permissions see section 3.1.3.1.

Problem areas with scarcity of water or 3.1.4.2.

conflicts among various consumers (domestic, industrial, agricultural and power production)

The water resources in the designated territory of Kardzhali and mainly the surface

flow of the rivers in the region are used by the industrial water sub-sectors of hydro

energy and water supply. There are very few irrigation systems and facilities on the

territory.

Domestic-drinking water supply

Main water consumers are as follows:

1. For domestic water supply

In the designated territory of ViK OOD Kardzhali there is one river water abstraction

from surface water for domestic-drinking water supply. Besides water from Borovitsa

Dam is used for the water supply of the towns of Kardzhali and Momchilgrad and 47

settlements in the municipalities of Kardzhali, Momchilgrad and Chernoochene.



2. For irrigation

A detailed description of the acting irrigation fields in the designated territory of OOD

Kardzhali, which are in the basins of Arda River and Byala Reka River and their

tributaries is given in Appendix 2.1. There are total of 6 irrigation dams on the territory

of Kardzhali District, which are serviced by “Irrigation Systems” EAD.

3. For power production

In the basin of Arda River and its tributaries included in the designated territory of ViK

OOD Kardzhali, constructed and operational hydropower facilities are: Dolna Arda

cascade, consisting of three dams – Kardzhali, Studen Kladenets and Ivaylovgrad and

three WPP below them. Of these only Ivaylovgrad Dam does not fall within the

designated territory of ViK OOD Kardzhali.

On the territory of ViK OOD – Kardzhali have not been established problematic zones

with water scarcity or conflicts between various consumers (domestic, industrial,

agricultural and power generation).

improving the water condition is an important factor for their protection, including the

respective sites under Natura 2000, determined pursuant to Directive 92/43/EEC and

Directive 79/409/EEC. In order to ensure the conservation of natural habitats and

species habitats, the plans, programmes, projects and investment intentions undergo

assessment for conformity with the subject and the goals of the conservation of the

relevant protected area. The terms and conditions for carrying out such an

assessment are laid down in Ordinance under Art. 31 of the Biodiversity Act.

Zones sensitive to biogenic elements, defined as se nsitive zones pursuant to

Directive 91/271/EEC and zones, defined as sensitive zones pu rsuant to

Directive 91/676/EEC

- All surface water bodies on the territory of ViK OOD Kardzhali, which are

categorized as water recipients in “sensitive zone” and part of them fall within the

requirements for nitrate sensitive zones (presented in section 3.1.2.3.).

- Wastewater from all agglomerations, which are in “sensitive zone” need to be

treated for removal of the biogenic elements of nitrogen and phosphorus to meet

the increased requirements. In the designed WWTP for the agglomerations of

Kardzhali, Momchilgrad, Ardino, Dzhebel and Benkovski are envisaged facilities

for increased level of reduction of the biogenic elements of Nt and Pt.



POTENTIAL POLLUTION THREATS 3.1.5.

Potential pollution threats for groundwater are point and diffuse sources of pollution.

Among the point sources for pollution are waste landfills, mill tailing dams, industrial

sites, mines, petroleum facilities and others. Diffuse pollution is mainly from

agricultural sources – agriculture and stock breeding.

The potential pollution threats in the area of the designated territory are among the

major problems having negative influence on surface water and groundwater quality.

Potential pollution threats for surface water are also point and diffuse sources of

pollution.

Table 3-17 Type of pressure used to determine water bodies in risk by different activities

Type of

Pressure Significant sector/Activity

1. Diffuse

pollution

- Urbanized territories without sewerage system and WWTP and lack of sewerage in

many of the settlements in the District. Domestic wastewater from population is

collected in septic tanks and creates real risk for groundwater and people’s health

- Production facilities and grounds of industrial plants and warehouses without

effective platform sewerage system, potential pollutants of soil and water (warehouses

for petroleum products, heavy oil holdings with unresolved past pollution, warehouses

for chemicals used as raw materials in industrial plants, etc.).

Risk of water and soil pollution above the standard is created.

- Agriculture – unregulated application of fertilizers non-compliant with the good agricultural

practice. Warehouses for pesticides and other means for plant protection.

- Stock-breeding –- farms, which do not apply the good stock-breeding practice,

uncontrolled accumulation of manure mass, flow of polluted wastewater, etc. There is

a risk of water pollution above permissible levels with biogenic elements, nitrogen

compounds, phosphorus compounds, etc.

- Waste landfills, unauthorized dump sites, uncontrolled accumulation of construction

and domestic waste in the outskirts of the settlements.

- Car repair and transport activity - washing the transport vehicles at places having no

sewerage, spill of oils and petroleum products, etc.

- Pollution with heavy metals in the regions with developed mining, mill tailing dams,

etc. – inefficient control and management of the sites create conditions for potential

pollution risk in case the environment protection requirements are not met.

2 Point

pollution

- Urbanized territories where settlements have sewerage systems but no WWTP: the

towns of Kardzhali, Momchilgrad, Krumovgrad, Ardino, Dzhebel, the village of

Benkovski and others (with forthcoming realization of wastewater treatment facilities)

and partially constructed sewerage of other settlements in the designated territory –

content of organic pollution in the receiving waters is increased, dissolved oxygen

content is decreased, nutrient content is increased, which leads to eutrophication,

conditions for negative impact on biodiversity and sustainable development of water

ecosystem are formed, the self-cleaning capacity of the water body is reduced.

Preconditions for health risk are created

– Industrial enterprises forming wastewater, which is directly discharged in the water

bodies with insuffiently efficient local WWTP or lack of such. Potential pollutants are

some food industry enterprises, transport enterprises, etc. in the designated territory.



Type of

Pressure Significant sector/Activity

In some areas of Arda River catchment area are found pollutants containing heavy

metals Cd, Pb, Ni and other from developed mining and metal ore dressing (limiting

are old pollution damages).

Arda River – from the town of Kardzhali to the border with the Republic of Greece –

pollution is registered in the following areas:

- Studen Kladenets Dam – wastewater discharge from OTsK Kardzhali and

accumulation of sediments at the dam tail. Single pollution cases are also registered

in the middle and at the dike of Studen Kladenets Dam;

- Arda River after Studen Kladenets Dam, periodical pollution is found at the bridge

between the village of Potochnitsa (municipality of Krumovgrad) and outside the

designated territory – the village of Rabovo (municipality of Stambolovo, Haskovo

District);

- stock-breading farms and others creating conditions for uncontrolled emergency

discharge of waters;

- Industrial enterprises forming wastewater, which is discharged in the sewerages of

the settlements without efficient local WWTP – this creates a risk of volley pollution of

the joint wastewater flow and can compromise the optimal water treatment in the

future WWTP.

“Water Supply and Sewerage” OOD Kardzhali and the municipalities have sufficient

groundwater and surface quantity and resources to meet the domestic-drinking and

other water needs of the people in the serviced settlements. There are no restrictions

on the use of surface water and groundwater for drinking water supply and other

purposes as their determined resources and water quality fully satisfy the

requirements in the relevant legal and statutory documents i.e. Water Act, Ordinance

№ 1/10.10.2007 on groundwater exploration, use and protection, Ordinance № 2

concerning the protection of waters against pollution caused by nitrates from

agricultural sources, Ordinance № 3/16.10.2000 on the terms and conditions for

investigation, design, approval and operation of sanitary protection zones around

water sources and facilities for domestic- drinking water supply as well as around

mineral water sources used for medicinal, preventive, drinking and hygienic purposes,

Ordinance № 9/16.03.2001 on the quality of water, intended for drinking purposes,

Directive 98/83/EC/ concerning the quality of water intended for human consumption,

etc.



3.2. WATER POLLUTION

MAJOR POLLUTION SOURCES

Water pollution sources are related to anthropogenic activities

Point sources of surface water pollution:

Point sources of pollution are the main reason for pollution of water bodies above the

norm and for deterioration of their chemical and ecological status. The main sources,

forming the total wastewater flow of the point sources of pollution are the population

and the industries in a given settlement. The population produces pollution load

characterised by the main indicators of BOD5 and COD, Suspended solids and

biogenic elements with organic content, demonstrated in the various forms of nitrogen

and phosphorus.

- Discharge of untreated wastewater from the sewerage collectors of the town of

Kardzhali – in Arda River, from the town of Momchilgrad – in creeks, tributaries to

Varbitsa River, from the town of Krumovgrad – in Krumovitsa River, from the town

of Ardino – in Ardinska River, from the town of Dzhebel – in Dzhebelska River,

from the village of Benkovski – in Varbitsa River and from other settlements with

partially constructed sewerage. Domestic and non-domestic wastewater is

discharged without treatment in rivers and creeks, thus polluting soil and

groundwater. This causes risk for the health of the population, unfavorable living

conditions, polluted environment.

- Discharge of wastewater from separate sites without industrial WWTP or with

such treatment facilities, which do not treat wastewater to the specified

requirements for the individual emission restrictions, according to the discharge

permits. The sites which activity forms biodegradable industrial wastewater – milk

processing sites, fruit and vegetables production, meat industry, have constructed

wastewater treatment plants but almost all sites have problems with the quality of

treated wastewater, which in many cases pollutes the recipients. Food industry

enterprises: milk processing enterprise in the village of Dobromirtsi, municipality

of Kirkovo, the brandy (rakiya) brewing facilities, ET “BIT-Penka Aladzhova”, town

of Kardzhali and others; hotel complex “Glavatarski han”, village of Glavatartsi

discharge wastewater unregulated near Kardzhali Dam and many other

enterprises and sites discharge their wastewater without sufficient treatment in

the water bodies.

- Many of the small agglomerations have partially constructed sewerage systems

and direct connections of some establishments, which poses health risk.

- Pollution from the developed mining and metal ore dressing with priority heavy

metals (cadmium Cd, plumbum Pb and nickel Ni) is found in the catchment area

of Arda River. Very poor is the water condition of Studen Kladenets Dam (tail),

where industrial wastewater from “OtsK” Kardzhali and untreated wastewater

from the sewerage of the town of Kardzhali is discharged. In this sector there are

sediments containing heavy metals and organic substances, accumulated in the



last decades. The River Basin Management Plan for East Aegean Sea Region for

2010-2015 envisages a measure for modernization of industrial WWTP and

providing suitable treatment, improving Kardzhali 2 mill tailing dam management

and constructing urban WWTP for the town of Kardzhali.

Diffuse sources of pollution:

Main sources of diffuse pollution are:

- Urbanized territories (sectors in the villages and other sites) without sewerage

system (using septic tanks, absorption wells, etc.). A big part of the wastewater is

usually discharged in the land layers and are prerequisite for pollution of points,

ground and surface water and posing health risk in the region

- Waste – unauthorised domestic solid waste landfills. Uncontrolled waste disposal.

- Stock-breading – uncontrolled accumulation of manure mass

- Road and railway transport, as well as activities related to transport maintenance;

- Industry – industrial grounds, warehouse areas of the companies, etc.

Industry – a source of wastewater pollution.

The industrial companies are situated mainly in the municipal centres with prevailing

number in the municipal centre – the town of Kardzhali. On the territory serviced by

ViK Kardzhali function industrial companies and the bigger part of them are connected

to the sewerages of the settlements or discharge independently in separate recipients.

Connected are companies from the food industry (production of bread and bakery

products, confectioneries, small factories for soft drinks, milk processing and meat

processing companies, etc.), wastewater from machine building enterprises, wood

processing, textile, transport companies, etc., which form wastewater with pollution

that will be included for reduction at the future WWTP as a ratio to the total burden.

Wastewater from the food industry is characterized by high content of organics,

suspended solids, biogenic elements and fat of plant and animal origin. Almost all

enterprises have constructed local WWTP but many of them does not treat the

wastewater to meet the requirements for discharge in the water bodies.

Wastewater from the wood processing and textile enterprises has pollution of

domestic type. Wastewater from machine building does not have organic pollution.

Wastewater from gas stations, car services and other transport companies is with

restricted organic pollution and contains grease and oil products (if the mud and

grease trap works efficiently no abnormal pollution is expected).

Wastewater from mining and ore dressing is polluted with heavy metals but with strict

control and efficient water management, and respectively treatment facilities,

wastewater pollution can be reduced to values, required by the current legislation.

*About 2,700 industrial and commercial enterprises with various activity, commercial

sites, sites in the sector of services and health care are functioning in Kardzhali

District – in the municipalities examined by the Master Plan. The list presented above

contains the more significant enterprises, which are expected to be larger sources of

polluted wastewater.

**The Consultant advices the WSS Operator to renegotiate the conditions for

connection of the industrial enterprises to the urban sewerage. The contracts, except

for the standard clauses, should include a requirement for measurement of

wastewater quantity before discharging in the urban collector, a schedule for the

implementation of self-monitoring coordinated with the RIEW and RHI.

*** The data on the pollution of wastewater from industrial enterprises is not presented

because it is based on single laboratory measurements and not an average amount

calculated for a longer period.

****The pollution load is determined on the basis of the invoiced water quantity.

IMPACT OF WASTEWATER DISCHARGE

Impact on surface water

Of greatest importance is the impact resulting from the point sources – untreated

waste water from the settlements.

In Aeda river and its tributaries currently is discharged untreated wastewater from the

population and the industry of the town of Kardzhali in Arda River, from the town of

Momchilgrad and the village of Benkovski in Varbitsa River, from the town of

Krumovgrad in Krumovitsa River, from Dzhebel in Dzhebelska River and it pollutes the

water at the point of discharge.

Surface water quality monitoring is carried out by the subdivisions of MoEW on the

basis of special programmes for surveillance and operational monitoring.

The main objective of surveillance monitoring programme is to provide comprehensive

and detailed summaries of the ecological and chemical status of the various water

bodies, by identifying the base line of their status and ensuring option for classification

of the water sites in five categories according to the statutory definitions.

In general, the frequency of monitoring is consistent with the variability in parameters,

obtained as a result of natural or anthropogenic conditions.



The surface water monitoring points in the designated territory are included in the

Operational monitoring programme of water bodies falling within «river » category in

Arda River Basin

Besides the physicochemical analysis of water, Assessment of water bodies status

through hydro-biological control is also performed. All necessary measures to

minimize the level of ecological risk are undertaken. Appendix 3-4 presents data for

the water monitoring in the period 2008-2012.

Impact on groundwater

The main risks for groundwater pollution are as follows:

• Pollution by authorized and unauthorized waste landfills and dump sites in the

settlements of the designated territory, which are not compliant with the

statutory requirements and causing pollution problems of shallow aquifers and

deep aquifers;

• Uncontrolled use of fertilizers and pesticides for agricultural purposes causing

high concentrations of nitrate in shallow aquifers. There is a risk that deep

aquifers will be concerned in the future and that larger amounts of

groundwater will be contaminated, which will result in a risk for all settlements;

• Exfiltration of wastewater from leaking sewerage networks.

• Exfiltration of wastewater from on-site sanitation facilities (leaking septic tanks

and latrines) can more specifically cause risk of polluting the settlements with

population below 2 000 P.E.

SLUDGE MANAGEMENT AND DISPOSAL 3.2.3.

There are no constructed treatment plants for the settlements. From the research

done it was found that it is most appropriate to construct treatment plants, apart from

those in an on-going project as follows: WWTP from the town of Ardino, WWTP from

the town of Dzhebel and from the nearby villages of Paprat, Tyutyunche, Podvrah and

Chakaltsi, WWTP from the town of Kardzhali, WWTP from the village of Benkovski,

town of Krumovgrad and the villages of Polkovnik Zhelyazovo and Vransko.

Since there are no constructed acting treatment plants the sludge quantities are

defined based on approved project phases and our technological estimates and expert

assessment.

In the municipalities from Kardzhali District the exploitation of the old municipal

landfills is terminated before the appointed time. Until the construction and entering in

operation of the first cell of the Regional Centre for Waste Management in the town of

Kardzhali, domestic waste is transported to the site of the old landfill of the

Municipality of Kardzhali. The future Regional Centre for Waste Management will treat

inert, non-hazardous and hazardous waste, generated on the territory of the

municipalities of: Kardzhali, Momchilgrad, Dzhebel, Chernoochene, Ardino, Kirkovo,

Krumovgrad and Ivaylovgrad (Haskovo District). 4 reloading stations will also be



constructed on the territory of the municipalities of Ardino, Kirkovo, Krumovgrad and

Ivaylovgrad.

In the territory of the municipalities of Kardzhali, Momchilgrad, Krumovgrad, Ardino,

Dzhebel, and Benkovski there is an elaborated and adopted Water Management

Report. In the balance of waste is also included the sludge quantity from the future

wastewater treatment plant. Through the reloading stations the dewatered sludge will

be directed to the regional centre.

The technologies for sludge treatment and dewatering in the project designs meet

entirely the requirements of the national legislation.

In the region of the Municipalities of Kardzhali, Momchilgrad, Krumovgrad, Ardino,

Dzhebel, Kirkovo, so far there have been no study on the use of appropriate

agricultural and forest lands for fertilization or disturbed areas for restoration. No

studies on the use of dewatered sludge as a fertilizer in agriculture have been

conducted. The Feasibility studies and other studies carried out by different designers

envisage that sludge will be disposed of to a domestic solid waste landfill. The

consultant recommends this happens only for the time the quality of the sludge

generated in the wastewater treatment is analysed. Then, based on the results of the

analyses, it is necessary to follow the recommendations and sludge should be

directed to the respective utilisation sites. Sludge disposal to domestic solid waste

landfills is neither recommended nor funded by the EU.

The Consultant recommends determining an appropriate pilot site for which

prospective studies on sludge management for use in various fields have to be

conducted. The region has lands suitable for agriculture and forestry, i.e. particularly

appropriate for sludge utilisation. The required studies should include:

• Analysis and proposed regulatory changes regarding Bulgarian sludge

management

• Assessment of the industrial situation on the pilot sites

• Assessment of the existing sludge management on the pilot site

• Determination of potential agricultural uses on the pilot site

• Prospective actions with potential users

• Socio-economic actions and communications to educate the public

concerned

• Design educational courses

• Assistance in the implementation of contracts between operators and end

users of sanitation sludge

• It is recommended integrating the reuse of treated water from WWTP to this

sludge management approach. This is common for well-functining WWTPs

from the recent past.

The requirements for preparation of projects for regional domestic solid waste landfill

necessitate that the volume of received waste should include the volume of sludge



and waste from the future wastewater treatment plants located in the surrounding

area.

The management of sludge from WWTP in the area is consistent with the

requirements of the national legislation in this field and is not expected to create any

insurmountable problems.

WATER QUALITY MONITORING

Wastewater from the settlements is usually the main pollutant of the respective river

basin. Water quality monitoring is carried out by RIEW Haskovo and Basin Directorate

for Water Management in East Aegean Sea Region for the wastewater from the

designated territory in Kardzhali District:

• Direct discharge into the water bodies (Arda River and its tributaries) of

wastewater collectors from the municipal centres: the town of Kardzhali, the

town of Momchilgrad, the town of Dzhebel, the town of Krumovgrad, the town

of Ardino, Chernoochene, Kirkovo and other settlements in Kardzhali District

with partially constructed sewerages.

• Direct discharge of wastewater from some sites with local WWTP and without

treatment facilities.

• Water quality monitoring on the territory serviced by ViK OOD Kardzhali is

carried out in the designated monitoring points:

Points for physico-chemical monitoring for determining the ecological and chemical

status of surface water.

- Varbitsa River at the village of Varli dol

- Krumovitsa River – before mouth

- Byala River – village of Meden buk

- Kardzhali Dam

- Studen Kladenets Dam – dam wall

Points for operational monitoring –

- Arda River before Kardzhali Dam

- Arda River after the town of Kardzhali

- Arda River after Studen Kladenets Dam (bridge village of Potochnitsa – village

of Rabovo)

- Arda River after the big curve at the town of Madzharovo

- Varbitsa River before Studen Kladenets Dam

- Byala River before the border

- Studen Kladenets Dam – middle part

- Studen Kladenets Dam – tail



At these points is carried out hydrobiological and physico-chemical monitoring for

determining the ecological and chemical status of surface water.

CONCLUSIONS AND RECOMMENDATIONS

The possibility for sampling points from the water bodies after the discharge of waters

from the future WWTP should be précised. After they enter a stable regime a Plan for

own monitoring is prepared to define the main parameters, characterizing the qualities

of the treated wastewater. These are the main parameters, which characterize the

qualities of the wastewater from WWTP of the settlements pursuant to the discharge

permits and it is necessary to monitor for: suspended solids, BOD5, COD, Nt, Pt, pH.

and water quantity. In order to control the work of the separate facilities operational

monitoring is carried out of the work and optimization of the technological processes in

the WWTP by parameters, determined by a schedule after the biological stage enters

stable regime. The status of the sludge formed in the process of treatment is also

monitored in relation to their treatment (disposal and/or utilization).

WATER BALANCE AND NON-REVENUE WATER ASSESSMENT

Methodology:

The table below presents a standard water balance, according to IWA. The main

components of the water balance are: Total drinking water produced, billed (sold)

water and unbilled water, which is the difference between total water produced and

water sold. According to IWA, the unbilled water itself is divided into several

components.

Detailed information:

• [Q]: total water produced and delivered to the settlements of Peshtera

Municipality. It is determined by means of water meters, installed on the

feeding pipelines and according to the flow rates of the water sources.

• [A]: total consumption invoiced to all customers who are equipped with water

meters

• [B]: total consumption invoiced to customers without meters (this is by

definition an estimate); there are no such customers on the territory of ViK

OOD Kardzhali



• [C]: total consumption that is metered but not invoiced (consumers, who get

free water, but on legal ground for this –there are no such customers on the

territory of VKS OOD Kardzhali

• [D]: total consumption that is neither metered nor billed, but authorised,

consumption by fire hydrants or fountains, reservoir washing, flushing of filters

at the treatment plants, etc. this is by definition an estimate

• [E]: water that is stolen through illegal connections or other means; this is by

definition an estimate

• [F]: water that is consumed by metered customers whose water meters

incorrectly record water(less water than the real consumption)

• [G]: water that is lost due to hidden leaks or failures on the pipelines

(transmission and distribution); it is given on the basis of observations and

assumptions of WSS company staff. No precise studies and measurements

have been conducted.

• [H]water that spills from reservoirs and service tanks; there is currently no

such water

• [I]: water that is lost due to hidden leaks or failures on the service connections;

it is given on the basis of information provided by WSS company staff. No

specialized measurements have been carried out.

The following assumptions were made to determine the components of water balance:

� Results of the assessment

Table 3-27 Assumption for assessment of water balance components

Losses Assumptions

Non-revenue water

Total non-revenue water is calculated as the difference between the total

water quantity supplied to the water supply systems (water produced)

and the total quantity of water billed (sold). For unmetered water sources,

the quantity of the water has been estimated based on their seasonal

discharge quantities.

Data on water produced and water billed water are provided by

„ViK“OOD Kardzhali

Unbilled metered

consumption

On the territory of „ViK“OOD Kardzhali there are no customers with water

meters the consumption of which is not metered, i.e. there are no

consumers who legally get free water.

Unbilled unmetered

consumption

This water quantity is mainly produced as a result of backwashing of

filters and from water intended for periodical washing of water chambers

of the pressure reservoirs as well as to a lower degree due to fire hydrant

or public fountains.



Losses Assumptions

Unauthorised

consumption

Based on information provided by the WSS operator, there are a certain

number of illegal connections to the distribution networks. Their exact

number is difficult to establish, except when the street water distribution

pipelines are replaced.

It is assumed that ≈10% of delivered water is used as unauthorized

consumption. We point out that it is not sure that after finding the illegal

connections, this unauthorized consumption will turn into authorized one.

It may be presumed that in the best case between 1/4 and 1/5 of it will

become legal consumption. The remaining part will be dropped out as

consumption.

Metering Inaccuracies and

data error correction

Based on information provided by ViK“ Kardzhali OOD – 100% of the

registered consumers have water meters, including the private, public

and industrial ones.

The data from all water meters are read on a monthly basis. According to

the conducted inspections of the old water meters, 80% of these water

meters give indications lower that the real flows.

The exact accuracy of water meters is not known. According to ViK

Kardzhali OOD the metering inaccuracy results in apparent (commercial)

losses of about 10 to 11% of delivered water.

Real Losses in the

network

The physical losses in the network result from invisible leakages, visible

failures, reservoir overflow, drawdown of distribution networks for repair

works or in case of breakdowns, etc.

Real losses are calculated as a difference between non-revenue water

(unbilled water) minus the above mentioned types of losses.

Based on information provided by ViK“ Kardzhali OOD about 1/3 of the

real losses in the network are formed due to failures and leakages at

service connections

CONCLUSIONS AND RECOMMENDATIONS

Conclusions:

It is striking that water losses in the water supply systems of ViK Kardzhali OOD are

too high, but not unusual for the water supply in Bulgaria. Losses within that range

indicate poor condition of the water supply systems, in terms of their physical state

(failures, leaking pipes. etc.), as well as with regard to water metering accuracy (i.e.

water produced and consumed).

Based on the assumptions for unauthorized consumption and metering inaccuracies it

can be assumed that the actual domestic consumption exceeds the officially billed

consumption.

In 2011 the billed water quantity for the population compared to 2009 was:

- For Kardzhali: 16,334 m3/year more

- For Momchilgrad: 17,461 m3/year more

- For Krumovgrad: 17,662 m3/year more

- For Ardino: 299 m3/year more

- For. Dzhebel: 13,964 m3/year more

- For Benkovski: 5,361 m3/year more

Based on the above analysis of the domestic, industrial and public consumption a

conclusion can be drawn that the average total water domestic consumption for the

present settlements ranges about 63 - 143 l/inh./day, industrial consumption varies

according to the existing industries and is average about 25 l/inh./day , and public

consumption ranges between 10 – 43 l/inh./day. The overall total water consumption

rate of all settlements except Benkovski village is below 160 l/inh./day.

Recommendations:

Systematic measures should be undertaken to reduce losses.

The measures proposed for reducing real/physical losses are as follows:

- Replacement of old water transmission (external) mains.

- Replacement of old water distribution pipelines and the service connections to them

- Timely repair of failures on the water pipelines.

- Systematic detection, localization and repair of leakages (breakdowns)

The activities necessary for reducing commercial losses are:

- Installation of water meters on all water transmission mains after the water sources.

- Installation of water meters on feeding pipes of reservoirs

- Implementation of the programme for verification and replacement of water meters of domestic consumers.

- Detection and interruption of unauthorised water connections



3.4. WATER SUPPLY INFRASTRUCTURE

GENERAL FEATURES

The water supply system of ViK Kardzhali is intricate and complex, consisting of 104

systems with gravity and pump supply and supplies water for the purposes of

households and industry. A large number of the systems - 41 are included in a

SCADA system. The water supply system of "ViK" OOD - Kardzhali provides water

to the population, industry and business in 7 municipalities: Kardzhali, Momchilgrad,

Krumovgrad, Ardino, Dzhebel, Kirkovo and Chernoochene and supplies population of

135,274 inhabitants. The water supply systems are presented in Appendix 3-6. A large

number of water sources satisfy the water needs in the region. The existing 244

settlements are supplied by 72 separate water sources (26 catchments, 1 river intake,

30 shaft wells, 8 drainages, 6 tube wells and one dam – Borovitsa. The total length of

the water supply network of ViK OOD Kardzhali is 787 km and it transports the water

to 244 settlements with 523 km distribution water mains, 1 DWTP – at Enchetz village.

The table below presents the length of the transmission network of ViK Kardzhali with

material and age of the pipes.

Water supply services are provided to 88 % of the population on the territory of ViK

OOD – Kardzhali – 135,247 people. The total quantity of supplied water in 2011 is

10,091,067 m3/year which compared to the invoiced quantity to households and

business of 5,059,738 m3/year determines a non-revenue water percentage of ViK

EOOD Kardzhali of 51 %. The regulated water volume of all reservoirs is 43,020 m3.

The number of lifting pumping stations is 112.

The water supply systems on the territory of the 7 municipalities are served entirely by

ViK Kardzhali OOD. Six systems in the scope of ViK Kardzhali have been examined:

- Water supply system of Kardzhali

- Water supply system of Momchilgrad

- Water supply system of Krumovgrad

- Water supply system of Ardino

EXTERNAL WATER SUPPLY SYSTEMS

Water supply system of Kardzhali

3.4.2.1.1. General features

The water supply of the town of Kardzhali comes by gravity from Borivitsa dam with a

drinking water treatment plant situated near the village of Enchets at about 6 km from

the town of Kardzhali. Water is transported by two steel water mains - Ø600mm to the

town reservoir with V=13,000 m3 and Ø530mm to DC at the reservoir for high zone

with V=5,000 m3 (only one chamber with volume V=2500 m3 is built) and for the water

supply of the town of Momchilgrad. The reservoir volume provides 24-hour reserve of

water.

The high zone of Baikal quarter after the hospital district, the Mental hospital and the

village of Sipei are supplied from PR V=280m3, supplied by PS Baikal.

The Prileptsi quarter is supplied with water from PR V=600 m3, which is supplied by

the trunk water main from DWTP „Enchets“ to PR V=5000 m3. At the site of the

reservoir is built a PS which supplies water to PR V=100m3, for the water supply of

Prileptsi.

Borovets quarter is supplied by PR 600m3 which is supplied by PS “Borovitsa”.

*Note: for the purposes of the report the Consultant has put a border between the

systems of Kardzhali and Momchilgrad at the distribution chamber at PR 2500 m3

„High zone” of Kardzhali. Thus we assume that the system of Momchilgrad starts at

the DC. See section 4.3.2.2.1. Water supply system of Momchilgrad.

3.4.2.1.3. Water treatment

Water coming from Borivitsa dam is raw surface water and must be treated before

supplied to the population. For this purpose in 1989-90 was built and commissioned a

drinking water treatment plant with design capacity of 800 l/sec. At present it treats

430 l/sec of water from „Borovitsa” dam. The quality of the inlet water according to an

analysis performed at the laboratory of the treatment plant is as follows:

The water becomes turbid regularly as in the recent years the inlet water turbidity

varies in wide ranges reaching and exceeding 100 mg/l. The technological design of

the treatment plant includes reagent treatment of the inlet water, sedimentation

installation, filtering installation, ozonation and chlorine disinfection. The water flows

into the treatment plant in an inlet chamber and then into a mixer.



Figure 3-1 Enchets DWTP– administrative and laboratory building, inlet chamber, aeration mixer,

radial sedimentation tanks

Here are introduced the reagents and the flocculant. Due to the electrical potential

resulting from the hydrolysis of the coagulants, the turbid particles are diverted

electrically and stick to the coagulant forming bigger and heavier clots. For speeding

up the sedimentation process the technological design envisages also introducing

flocculant. This is a long-chain polymer which has the capacity of attracting coagulated

particles, sticking them together and settling them in the sedimentation installation.

The homogenization of the introduced coagulants and flocculant with the water is

done by intensive bubbling with air. It is worth noticing that the sludge is taken out of

the sedimentation tanks manually. The tank which must be cleaned is switched off and

the sludge is removed manually. This is unacceptable and must be corrected. If

actually the bridge sludge-removers cannot perform the sludge removal another

appropriate solution must be found including changing the type of the sedimentation

tanks. Despite their sufficient experience the operating staff is not always capable of

separating the inlet turbid particles. In our opinion the reasons for this are two: first the

deforestation of the slopes of Borovitsa dam causes erosion processes and during

intensive rainfall the quantity of the wash in the dam is highly increase and results in

increased turbidity. Here we must make an additional comment in view of the

Consultant’s apprehensions. Increased turbidity due to continuous erosion is not such

a big problem. However what is more worrisome for this region rich in ores (especially

of heavy metals) and with an active lead-zinc concentrate processing plant which

pollutes the environment with respective emissions, is that this exposure due to



erosion is most likely to result also in leaching of hazardous substances for the

treatment of which the treatment plant is not equipped. Secondly, we have established

that the reagent installation- sedimentation complex is not well designed. The

reagents and mostly the flocculant are not the most appropriate for the inlet water. .

The settled water undergoes filtering in the filter installation. Though the plant is

relatively new the condition of the pipes and most stop valves in the space below the

filter installation is not good. Corrosion is in very advanced stage and causes

problems during the execution of the technological operations. The filtered water is

then ozonated and disinfected. The chlorine supply system is new and in good

condition but the system providing the safety of the operating staff must be fully

renovated.

Figure 3-6 Ozonation station

For the filtering sludge and the sludge form the sedimentation installation are

envisaged and utilized treatment facilities. The sludge generated after the dewatering

must be disposed at a SHW landfill since it is not suitable to be used of other

purposes.

There are designs for this DWTP which are currently not approved for funding,

examining the issue of turbidity removal by preliminary ozonation. The existing

installations are envisaged to be reconstructed and new ones are planned to be built.

There will be a suspension chamber in which a suspension film will form. When water

flows through it will catch and collect the particles which cause turbidity of the water.

The process will be intensified by acidic ozonation by introducing ozone in the water

with pressure ejection diffusion. The settled water will be then transported to the

filtering installation and the sludge will go into a sludge chamber from where it will go

to regular treatment and dewatering.

Table 3-36 Summary of the main deficiencies in the main water supply system of Kardzhali

№ Components Main deficiency

1 Water

treatment

(purification

and

chlorination)

Water coming from „Borovitsa” dam regularly becomes very turbid. The

regent treatment does not always have the expected results. The

chlorination compartment is not safe for the operating staff. The input

chlorine is not dosed precisely according to the quantity of residual

chlorine in the water.




2 Transmission

water mains

The material of which the water supply pipes are made and their condition

influence the risk of external pollutants entering the pipes in case of leaks.

5 breakdowns were registered on the external trunk water mains in 2011.

All trunk water mains made of steel and asbestos cement carry risks due

to the high number of breakdowns on them. Their replacement is pressing

for achieving security of the water supply of Kardzhali.

A serious problem in terms of the continuous and secure water supply

comes from the water main from Borovitsa dam to DWTP „Enchets“, since

its route of 26.5km crosses highly divided and accessible areas which

makes it operation difficult. The time for repairing breakdowns sometimes

exceeds 24 hours. The water main is made of steel pipes Ø900 and Ø800

and is in bad operating condition.

Recommendations for repairing the above deficiencie s:

1.Water treatment (purification and chlorination)

Overall reconstruction of the inlet installation is required. We consider advisable to

examine the combination of coagulants and flocculants and the order of their

introduction to the inlet water. It is very important to choose the most appropriate

flocculant. The manual cleaning of the sedimentation tanks is inacceptable. The

operation of the bridge sludge removers and the mechanical removal of the sludge

must be resumed. Turbidity meters must be installed at the sedimentation tanks for

preventing high levels of settled coagulated substance and automatic release of

sludge depending on the level not only on the time. We recommend the

implementation of a SCADA system for the entire plant and employing controller

based management instead of relay automatisation of processes. All the information

from the various basic technological points of the plant must be imported in this

system. We recommend renovation of the electric and mechanical equipment and

especially of the equipment for chemical treatment of the water. The command levels

in all vessels and reservoirs must be registered using a non-contact method –

ultrasound, infrasound, radar or similar. All contact or capacity level detectors are

unsuitable for hard water and for chemical treatment of the water. Nowadays there is a

vast selection of appropriate devices.

Regarding the design for preliminary ozonation assigned by the MRDPW we

recommend that a test with the existing ozonizers to be carried out and only after

receiving the necessary parameters a solution with new ozonizers to be researched.

The first suspension separators designed and manufactured by Degramon were

installed in the DWTP Sofia in 1968. However the maintenance of the suspension film

proved rather fickle and the treatment effect was much lower than expected. We

believe that ozonation is not the most appropriate method for removing turbidity of

water but it is good that it is installed at the plant since considering the current state of

affairs and the increasing pollution of the inlet water the plant will probably have to

treat more serious pollution as well.

We consider that the complete renovation of the installation for deactivation of chlorine

gas eventually leaking from the system in case of damaged hermetic tightness,

leaking storage vessels or emergency condition with spontaneous leaks of chlorine



gas from the storage vessels is absolutely pressing. We propose the ozonizers to be

put in operating readiness regardless of the availability of means for their operation

due to the high energy consumption. These facilities help the water treatment in

critical conditions of pollution and must be used though rarely.

2. Transmission water mains

An overall reconstruction of the steel and asbestos cement water mains is necessary

as the priority is the trunk water main from Borovitsa dam to DWTP Enchets.

Water supply system of the town of Momchilgrad


The water supply system of the town of Momchilgrad consists of two sub-systems:

- the first system from PS „Zagorsko” pumps the water quantity by a suction

reservoir 150 m3 from 6 bunker PS, situated near the site of the PS. It supplies

PR 200 m3 of Zagorsko village which supplies water to the villages of

Zagorsko, Progres, Chukovo, Bagryanka and Sokolino and to PR 3,000 m3

supplying Momchilgrad.

- the second system* supplying Momchilgrad is from Borovitsa dam which

starts from the dam to DWTP „Enchets”, from which the treated water is

supplied to Kardzhali, Momchilgrad, the villages of Gluhar, Makedontsi,

Dazhdino, Pepelishte, Balabanovo, Gruevo and Gradina. The town of

Momchilgrad is supplied from a Relief chamber 10m3 to the internal water

main network of the town.

treatment

(purification

and

chlorination)

It has been established that the water coming from DWTP Kardzhali has

residual chlorine quantity below the regulatory level. Additional

disinfection with sodium hypochlorite has been envisaged and is

implemented. The disinfectant is dosed manually.

The water from the shaft wells is disinfected with sodium hypochlorite at

PS Zagorsko. The disinfectant is not supplied proportianlly and is not

measured according to the quantity of residual chlorine in the water.

3 Transmission

water mains



3 breakdowns were registered on the external trunk water mains.

All trunk water mains are made of steel and carry risks due to the high

number of breakdowns on them. Their replacement is pressing for

achieving security of the water supply of Momchilgrad

4 Water metering There is no sufficient number of water meters installed at the water

sources and at the inlet of the reservoirs. Water supplied in the external

system is not metered precisely.


1. Water sources

Pursuant to the above described condition of the water sources and for providing their

future normal operation rehabilitation and reconstruction of the pipe systems and

updating of the water use permissions for the SW at PS Zagorsko must be done.



2. Water treatment (purification and chlorination)

At the distribution chamber before Momchilgrad we envisage a chlorination

compartment to be built with equipment for supplying sodium hypochlorite pursuant to

the standard requirements and the good practices. The automatic management of this

disinfection station must be complied with the quantity of the residual chlorine in the

water.

At PS Zagorsko we envisage the complete rehabilitation of the existing chlorination

compartment for supplying disinfectant in compliance with the requirements of the

standard and the good practices.


The transmission water mains made of steel pipes with a big share of breakdowns

must be reconstructed and replaced with ones made of new and contemporary

materials. More specifically this refers to the steel water mains RC High zone

Kardzhali to RC Momchilgrad , as well as the steel pressure main from PS Zagorsko

to PR 3,000m3 of Momchilgrad.

For the rest of the water mains better operation and maintenance and gradual

replacement are necessary for achieving better security of the water supply of the

respective agglomeration.

4. Water metering

New water meters at the outlet of each water source must be installed or the old ones

replaced. Regular inspections of the existing water meters are mandatory for obtaining

actual data for the supplied water quantities.

Water supply system of the town of 3.4.2.3.

Krumovgrad


The water supply system of the town of Krumovgrad consists of one PS”Krumovgrad -

1” which supplies the two PR 700 m3 and PR 1,000 m3, which supply the town. The

PS is situated in the town. It abstracts water from two SW located at a site on the

terrace of the Krumovitsa river.

For PS Krumovgrad 1

The water coming from subsystem 1 is only disinfected with chlorine gas

supplied according to the pump capacity not proportionally to the flowing

water quantity. The input chlorine is not dosed precisely according to the

residual chlorine quantity.

No chlorine deactivation system has been envisaged in case of eventual

damaged hermetic tightness of the installation.

The water coming from subsystem 1 is only disinfected with sodium

hypochlorite by a pump but not proportionally to the flowing water

quantity. The input chlorine is not dosed precisely according to the

residual chlorine quantity.

3 Transmission

water mains




All trunk water mains are made of asbestos cement and carry risks due to

the high number of breakdowns on them. Their replacement is pressing

for achieving security of the water supply of Krumovgrad

4 Water metering There is no sufficient number of water meters installed at the water

sources and at the inlet of the reservoirs. Water supplied in the external

system is not metered precisely.




1. Water sources



updating of the water use permissions for the SW at PS Krumovgrad ” must be done.


We envisage renovation of the chlorination installation at PS Krumovgrad 1, as the

installation will supply the disinfectant proportionally to the flowing water quantity and

the dosage will be measured in compliance with the residual quantity of chlorine in the

water. We envisage also completing the system with a chlorine deactivation

installation for eventual leaks in the system due to damaged hermetic tightness of the

system and the chlorine storage tanks.

The disinfection at PS I uplift for Izgrev quarter will be renovated and a storage and

dosing facility for the disinfected will be envisaged and a system for supplying the

disinfectant proportionally to the flowing water quantity and measuring the dosage in

compliance with the residual quantity of chlorine in the water.

3.Transmission water mains

The transmission water mains made of steel and asbestos cement pipes with a big

share of breakdowns must be reconstructed and replaced with ones made of new and

contemporary materials. More specifically this refers to the water mains from PS

Krumovgrad” to PR 1000 m3 and the water main from it to PR 700 m3.

The water supply system of Ardino consists of three sub-systems:

• The first sub-system – water from a karst spring on the territory of

Pravdolyub village is supplied to PR V=400m3, which supplies water to the

high zone of the town and by gravity to two pressure reservoirs – PR



V=1000m3 and PR V=500m3 supplying the low zone. Pumping station

„Pravdolyub” situated on the site at the PR V=400m3 supplies PR V=180m3,

which supplies water to Beli Brezi. Water is supplied to PR V=180m3 also by

an old PS „Belite brezi“, which is used rarely as a backup source.

• The second sub-system – water from 2 shaft wells with bunker PS is

supplied to PS „Ardino“ which supplies PR V=1000m3, PR V=500m3 – low

zone and PR V=400m3 – high zone. Near PS „Ardino“ is located PS „Ardino –

old“, which is used as a backup source.

• Third sub-system – water from 3 springs in Daldzhata area is supplied

directly into the network of the town.

system of Ardino, 9 in the system of Benkovski, 12 in the system of Dzhebel, 2 in the

system of Krumovgrad, 5 in the system of Kardzhali and 3 in the system of

Momchilgrad. It is worth noticing that the systems in which the water is transported by

pumps have higher number of breakdowns (Dzhebel and Benkovski ) compared to

systems supplied by gravity.

With total length of the water mains of the 6 systems (zones) supplying water – 93.06

km in 2011 the number of breakdowns per km was 0.408.

Despite that the external water supply systems are mostly olf and made of the

unreliable asbestos cement and steel pipes as a whole the water supply to the urban



agglomerations of Kardzhali, Momchilgrad, Krumovgrad, Ardino, Dzhebel and

Benkovski is relatively secure.

Water losses:

According to information provided by ViK Kardzhali probably about 10% of the

technical losses in the water supply systems come from the external water mains –

this is ≈ 70,705 m3/year (most of them come probably from small hidden leaks which

are hard to detect or never detected).

Energy efficiency:

The assessment shows that

The pumps in the existing pumping stations of the systems are relatively new and are

in good or satisfactory condition. There is no increased energy consumption or

reduced capacity observed.

Kardzhali

Water main network

The share of water supplied population in the town of Kardzhali is 100% and the water

supply infrastructure is fully built at present.

The existing water main network of the town is built of asbestos cement pipes, steel

pipes and polyethylene pipes. The total length of the water mains is about 88.3 km

and they were built mainly in the 1950-60’s. The off-balance sheet assets are about

3.3km (owned by the Municipality or another authority). At the entrance of the town is

installed an indirect operation pressure regulator with membrane motion with diameter

Ø600 mm. The pressure regulation helps reduce the breakdowns in the distribution

network.

Information about the length, material and diameters of the distribution network is

presented in the table below. Most of the problems of the water main network come

from asbestos cement and steel pipes.

3.4.3.1.1. Water metering

According to data obtained from „ViK” OOD – Kardzhali – 100 % of the registered

consumers have water meters. All households registered as consumers have water

meters. Apart from the individual water meters for consumers, all blocks of flats are

provided with main water meters. All public and industrial consumers (large and small)

are endowed with water meters.

Water meter reading is carried out on a monthly basis. There is an approved schedule

for verification and calibration or if necessary for replacement of water meters. This

schedule is chiefly performed for the main water meters and insufficiently for the small



(house) water meters. (According to the legislation, verification and calibration should

be conducted every 5 years.

Breakdowns in the water mains and water supply inse curity

According to the data provided by the Operator, the total number of breakdowns in the

distribution network of Kardzhali in 2011 was 326 breakdowns per year, 295 on the

street water mains and 31 on the service connections which means 3.69

breakdowns/km per year. The number of breakdowns in Kardzhali is very high. It

should be considered that the number of failures mentioned above applies to the

visible leaks and breakdowns.

According to the data provided by the Operator, the breakdowns in the network of

Kardzhali occur in different areas and on various pipe sections. No zones featuring

high failure rate were outlined. Again, according to the information of the Operator,

failures take place most frequently on asbestos cement pipes and steel pipes.

Despite the substantial number of failures, water delivery to consumers is sufficiently

well guaranteed. Water supply is disconnected in a given quarter or quarters only

during the performance of intervention works for the respective failure.

Water losses:

Non-revenue water assessment for the entire water supply system of Kardzhali is

presented in Item 3.3.2 Water Balance and Non-revenue Water Assessment – Table

3-28 and Appendix 3-7 (Table 2).

Real losses in the distribution network are estimated to 46 % of the total water input of

the distribution network. We emphasize that no accurate measurements have been

conducted by the Operator in order to determine the losses in the network.

With reference to Chapter 3.3.2 Water Balance and Non-revenue Water, it can be

seen that non-revenue water equals 52 %, and a major part of it is due to real losses

which are estimated to be about 46 % of the total system input. Real losses in the

street distribution network and service connections in Kardzhali are estimated at about

37 % of the water supplied to the network of Kardzhali.

Deficiencies:

• Frequent breakdowns of pipes as a result of the outdated and amortised distribution network

• 55 % of the real losses come from service connections

Water main network

The village of Benkovski is supplied from PS „Benkovski which supplies water in PR

V=140m3 at the village of Yagnevo and from there by gravity to PR V=160m3 at the

village of Veslets (northern zone of Benkovski).



The total length of the existing water main network of Benkovski is about 7km. Most of

it was built in the 1970’s from asbestos cement pipes with Ø125, Ø100, Ø80 and Ø60

and steel pipes DN100. About 0.6km are built of new polyethylene water mains.

Table 3-104 Summary of the main deficiencies in the distribution network of Benkovski


1 Water Distribution

Network

92 % of the existing water main network is made of asbestos cement and steel pipes which causes high number of leaks and frequent breakdowns. Water supply is unreliable due to interruptions of the supply during the period of repairing the breakdowns. Most of the settlement water main network is not connected, which contradicts Ordinance No 2 for the design, construction and operation of water supply systems Part of the water main network of Benkovski does not comply with the requirements of ORDINANCE NoIз-1971 of 29.10.2009ON THE CONSTRUCTION AND TECHNICAL RULES AND STANDRADS FOR FIRE SAFETY in terms of the necessary number of fire hydrants for shutting down zones up to 5 fire hydrants and the required number of the fire hydrants. For settlements below 100,000 inhabitants the distance between the fire hydrants must not exceed 150 m.




2 Service

Connections

The total number of service connections is 820 mainly built of galvanized steel pipes which are highly corroded and are the main reason for water losses in the town. The service connections are in poor condition and are a source of breakdowns and water losses 90% of the service connections are made of galvanized steel pipes

3 Water metering Inaccurate metering of water supplied to the network A large number of old water meters (80% of the verified water meters are inaccurate and measure smaller quantities)

4 Pressure reservoirs

Reservoirs need better operation – fighting the external corrosion of the pipes and fixtures, replacement of old SV, pipes, rails, stairs, etc.

There is a project prepared for the settlement: “Completion of the sewerage network,

reconstruction of the water distribution network along the routes of the new sewerage

system and a WWTP of the village of Benkovski, Municipality of Kirkovo”– pre-

investment study stage which is part of Priority Axis 1 “Improvement and development

of the drinking water and wastewater infrastructure in agglomerations between 2,000

and 10,000 PE” of Operational Programme Environment 2007-2013.”

According to information provided by the WSS operator the total number of

wastewater service connections served by ViK OOD Kardzhali in the entire service



area in Kardzhali District is 5,946. A total of 536 breakdowns have been registered on

the service connections in 2012. In the town of Kardzhali have been registered 62

sewerage network breakdowns and 504 service connection breakdowns in 2012.

The deficiencies of the existing sewerage network are as follows:

- In the opinion of the operating company and as a result of the on-site inspections

the physical condition of the pipes in the sewerage network built almost entirely

with concrete profiles is overall satisfactory in terms of cracks formed by static

loads but the sand-concrete mortar between the concrete pipes does not provide

the necessary impermeability due to cracks. The useful life has expired and the

pipes must be gradually replaced.

- There is infiltration of water in the sewerage network which leads to over-diluted

wastewater.

- Part of the wastewater quantity is disposed at the site of the WWTP and the rest is

discharged in the gullies and in the Arda River.

For completing the sewerage network of Kardzhali is necessary to be completed the

sewerage network and to be reconstructed the compromised sections of the existing

network. The construction of a WWTP is pressing. These issues are addressed in the

project “Integrated water project for Kardzhali: Construction of a WWTP and a trunk

collector, expansion and reconstruction of the water supply and sewerage network”

which has received grant funding and the CIW under which will be completed by the

end of 2014. The length of the network envisaged to be rehabilitated and built

amounts to 23.236 km.

Wastewater pumping stations 3.5.1.3.

The topography of the town and the location of the main collectors allow the domestic

wastewater and stormwater to be disposed of by gravity. There are no wastewater

pumping stations built.

Wastewater treatment facilities 3.5.1.4.

There are Pre-feasibility Studies (PFS) and Preliminary Design (PD) for the

wastewater treatment plant (WWTP) of Kardzhali agglomeration prepared and

approved in October 2012, including the main process schemes and parameters of

the future wastewater treatment plant (WWTP).

Wastewater treatment plant for Kardzhali agglomerat ion

According to the pre-investment studies and the preliminary design of 2012, the

wastewater treatment plant is designed for an operation period of about 30 years – till

the end of 2041 and with a capacity of 58,525 population equivalent (PE), including

those from the neighbouring villages: Rezbartsi, Prileptsi, Ayrovo, Opalchensko, Si[ey

and Petlino. The wastewater treatment plant of Kardzhali agglomeration is designed

for an average 24-hour quantity of wastewater of Qav.day = 9,141m3/d, including

1,332 m3/d of industrial wastewater and 1,850 m3/d of infiltrated water.



The receiving water body of the treated wastewater is Studen Kladenets dam on the

Arda River. The dam is of II-nd category pursuant to Appendix No 3 of Ordinance No

РД-272/03.05.2001 of the Minister of Environment and Water and belongs to the list of

Sensitive zones pursuant to Ordinance No РД-970/28.07.2003 of the Minister of

Environment and Water. Therefore the concentrations of the biogenic elements

nitrogen and phosphorus in the treated wastewater must comply with the requirements

of Ordinance 6, Appendix 3, Table 2. This has been taken into account in preparing

the Pre-investment studies and the Preliminary Design for WWTP and removal of the

biogenic elements nitrogen and phosphorus has been envisaged.

The terrain envisaged for the WWTP is situated in the eastern part of Kardzhali on the

left bank of the Arda. It is situated south of the boundaries of the production site of the

Lead and Zinc Production Plant. Plot 40909.14.71 - № 000103 has an area of 126.035

decares and is owned by Kardzhali Municipality. The plot designated for WWTP site is

located near Studen Kladenets dam with 223.0 - 228.0 m difference in levels,

according to the Baltic elevation system. The highest water surface elevations of the

dam reach an altitude of 227.40 meters, which means that about 90% of the plot,

designated for the WWTP is floodable. This underlies the proposal made in the pre-

feasibility studies and preliminary design for filling over the WWTP site to an elevation

of 227.20 - 229.00m with fortified slopes. The WWTP process scheme adopted in the

preliminary design includes technological stage for mechanical treatment and

biological treatment in aeration tanks with low pre-denitrification, nitrification and

combined biological and chemical phosphorus removal. Kardzhali WWTP process

scheme for water is described in the text below.

Table 3–108 contains the specific wastewater quantities as of 2041 used to size the

treatment plant as according to the preliminary design.

According to the adopted technological designs in the preliminary design of the

treatment plant are envisaged the following technological installations and facilities:

1. Technological installation for mechanical treatm ent

• Coarse screen.

• Pumping station. Raw wastewater from main collectors 1 and 2 will enter by

gravity the treatment plant at an elevation of 221.28. After the coarse screen

wastewater will be will be pumped (by three operating and one standby

pumps) to the treatment facilities and the overflowing stormwater quantity will

be pumped by another pump group (by four operating and one standby

pumps) into the bypass channel of the plant and discharged directly into

Studen Kladenets dam.

• Fine screen. It is envisaged to provide three parallel step fine screens (one

standby) with clear openings of 5 mm, located in a combined building right

before the grit chamber. The same building will also be occupied by the

facilities for compacting and backwashing the particles retained on the fine

screens as well as the sand classifier, the floating matter rotating screen and

the blowers to the grit chamber. The matters separated from the screens and

the rotating screen (rotostrainer) will be backwashed, compacted and

transported in containers to the domestic solid waste landfill (DSW).

• Grit chamber . There will be a two-corridor aerated grit chamber with a zone

for separating floating matter. The grit chamber will have two parts with a total

cross-section of 9.2 m2, length of 22 m. Sand will be removed by a centrifugal

pump and carried to the classifier in order to be dewatered. Floating matter

will be collected in a chamber and carried by a pump for dewatering in the

rotating screen (rotostrainer) with clear openings of 1 mm. Separated sand

slurry will be transported by sand pumps to the classifier in order to be

backwashed and dewatered, then it will be removed in a container for

eventual utilization.

• Primary sedimentation tank . Two radial primary sedimentation tanks with a

diameter of 15m and an average depth of 2m are envisaged.

2. Technological installation for biological treatm ent

• Aeration tank with selector , biological and chemical phosphorus removal.

The selector before the tank will have a total volume of 292 m3. The

anaerobic bioreactor (for partial biological phosphorus removal) consist of two



sections with corridor width of 6 m, length of 15 m and depth of 6 m and

total volume of 1,080 m3. The anoxic zone (denitrification zone) is designed

with two parallel operating sections with a width of 12.5 m, length 15 m, depth

6 m and total capacity of 2,243 m3. Nitrification (aerobic) zones are also two -

with corridor width of 15 m, length of 37 m, depth of 6 m and total capacity of

6,728 m3. There is a possibility for chemical settling of phosphorus using iron

trichloride, injected directly into the selector together with the recirculating

activated sludge as well as the respective reagent facility.

• Secondary sedimentation tank . There will be three radial sedimentation

tanks with a diameter of 25 m, average depth of 3.25 m and total capacity of

4,754 m3. Sludge is transported by radial scrapers along the bottom of the

facilities to the sludge chambers, from where it is removed by gravity and sent

to the pumping station for recirculated activated sludge, located next to the

selector. From there surplus activated sludge is repumped to the building of

the drum thickeners.

3. Technological installation for wastewater disinf ection

UV radiation installation . There will be high-pressure mercury lamps for ultraviolet

radiation, installed in an open channel. 4. Technological installation for sludge

treatment

• Mechanical thickener. Two rotating thickeners for partial dewatering of the

excess activated sludge up to 94 % humidity have been envisaged.

• Anaerobic digester. There will be one facility with a capacity of 2,200 m3,

operating in mesophile temperature mode (around 35° С). The primary and

thickened surplus activated sludge will be stabilised in the digester.

• Gas holder. The emitted gas will be stored in a gasholder with a capacity of

300 m3 from where it will be sent to the cogeneration installation for electricity

and heat generation having a total power capacity of 323 kWh.

• Silo . The stabilised sludge will be stored in a silo with a total capacity of 110

m3, which will serve also as a suction tank for the mechanical dewatering

system.

Belt filter press. There will be two belt filter presses for sludge dewatering up to a

humidity of about 78%. Each of the filter presses has a capacity of 10 m3/h of

dewatered sludge and will operate 6 hours a day. There will also be the respective

units for flocculent preparation and dosing and a belt conveyor for removing the

dewatered sludge to the site intended for its temporary storage. Table 3-110 presents

information about the expected concentrations of main pollutants in the treated

wastewater.

Quality parameters Unit Concentrations

BOD5 mg/l 25

COD mg/l 125

Suspended solids mg/l 35

Total nitrogen mg/l 15

Total phosphorus mg/l 2

The above parameters are compliant with the regulatory requirements for water

emissions discharged in water bodies of second category, sensitive zone.

Sludge treatment

The technological design of the adopted option I includes mechanical and biological

treatment in aeration tanks with nitrification, denitrification and chemical removal of

phosphorus.

The wastewater treatment processes generate sludge which must be treated

separately for its final disposal or utilization. The suggested technological design of

the wastewater treatment plant of Kardzhali agglomeration along with the wastewater

treatment facilities also includes sludge treatment installations.

The following technological installations and facilities have been envisaged for

wastewater treatment:

1. Mechanical treatment stage

2. Biological treatment stage

3. Wastewater disinfection stage

During the wastewater treatment processes waste and sludge will be generated and

collected in the following installations:

• Coarse and fine screens- screenings will be compacted and separated in

containers for removal from the treatment plant

• Grit chambers - retained grit will be washed, dewatered and separated in

containers for removal from the treatment plant. Separated oils and fats will

pass through rotating screen, from where it is envisaged to be sent for

utilisation .

• Primary sedimentation tanks - retained primary sludge, which is not

sufficiently well compacted due to the short residence time (32 min) will be

sent to mechanical thickeners and then for biological stabilization.

• Secondary sedimentation tanks - surplus activated sludge (mainly containing

biodegradable organic substances and a certain amount of phosphates (from

the chemical phosphorus removal) will be thickened in mechanical thickeners

and then sent for biological stabilisation.

For the biological stabilization and subsequent dewatering of the mixed primary and

compacted excess activated sludge have been envisaged the following facilities:



• Anaerobic digester – operates in mesophile temperature mode (around 35°

С), without removing sludge water, with volume of 2800 m3

• Belt filtering presses – for dewatering the sludge up to a humidity of about

78 %

• Sludge silo – reservoir for gravitational thickening and storage of stabilized

sludge before sending it for mechanical dewatering in belt filtering presses.

For the storage and utilization of the biogas generated in the anaerobic digester have

been envisaged the following facilities:

• Gasholder – membrane dry reservoir for storage and regulation of biogas

consumption with volume of 300 m3

• Cogeneration installation – for generation of electricity and heat energy from

biogas

• Boiler – provides hot water for heat transmission to the external speed

heaters of the anaerobic digester

• Steam boiler installation – powered by external fuel and designed to start

the operation of the anaerobic digester

Table 3-111 presents the quantity of waste and sludge expected to be generated in

the wastewater treatment plant of Kardzhali according to data from the PS for WWTP-

Kardzhali and the expert assessment of the parameters missing in this study.

According to information presented in the PS about the wastewater of Kardzhali on the

territory of the town operate a total of 21 industrial companies situated in 4 industrial

zones. They belong to the food processing, textile, machine building and furniture

industries and transport and generate a total average 24-hour wastewater quantity of

105.73 m3/d.



In compliance with the provisions of Ordinance 7 for the discharge of industrial

wastewater in urban sewerage networks and active control on water emissions from

industrial plants (according to the contract of each industrial company with the

Operator of the urban WWTP) the sludge from the treatment plant is not expected to

contain heavy metals above the permissible concentrations. This is a precondition for

its possible utilisation through fertilization of agricultural and forest areas.

Arable lands within Kardzhali Municipality may be a serious resource for utilization of

the future WWTP sludge as a fertilizer of agricultural land. For that purpose, after the

plant commissioning , its Operator should conclude the relevant contracts with the

owners or users of agricultural lands, suitable to be fertilized with sludge.

Such a possibility exists with respect to the use of sewage sludge for fertilization of

forest lands, for which the Operator of WWTP must carry out the relevant

administrative procedures.

A possible option for utilization of sludge from urban wastewater treatment plants is its

application for restoration of disturbed terrains. There are currently no data about the

existence of such terrains on the territory of Kardzhali Municipality.

Another alternative common for the current practice in our country is sludge disposal

to a domestic solid waste landfill (DSW). There is a possibility that Kardzhali

Municipality disposes WWTP sludge to the designated site of the regional domestic

solid waste landfill (DSW). However, this is neither recommended and nor funded by

the EU institutions.

The present Regional Master plan recommends the sludge from the future wastewater

treatment plant of Kardzhali agglomeration to be disposed of at the regional SHW

landfill until it becomes clear whether the agriculture and forestry are ready to accept

the sludge for utilization and after implementing the respective administrative

procedures.

Efficiency of the wastewater system 3.5.1.5.

The overall efficiency of the system is summarized as follows:

Operation and maintenance of the sewerage network:

• The operator carries out seasonal (spring and autumn) preventive

maintenance including cleaning and other activities and for problematic

sections and emergency situations the Operator employs specialized machine

cleaning services.

• No preventive maintenance and inspection is conducted through CCTV

observation of wastewater network.

Operation and maintenance of WWTP :

WWTP-Kardzhali is not built yet. A detailed operating instruction guide is being drafted

for the facility which envisages the mode of operation and management of the main

and auxiliary installations of the plant. The documentation of the operating equipment

contains maintenance instructions for types of planned repairs and the useful life of



the parts breaking most often which should be replaced. Above all the Energy

Engineer of the plant must be familiar in detail with the technology and specifics of the

equipment and the spare parts must be envisaged and delivered on time. The heart of

the plant lies at the command dispatch station where the SCADA system shall be

installed and the regular maintenance of this system will guarantee the safe and

smooth operation of the plant.

Summary of the main deficiencies 3.5.1.6.

The next table presents a summary of the main deficiencies in Kardzhali

agglomeration. The notes are prepared based on the EU Directive for solid waste and

According to information provided by the WSS operator in the town of Momchilgrad

have been registered 9 breakdowns on the sewerage network and 19 breakdowns on

the wastewater service connections in 2012.


- The sewerage network pipes have small diameters Ø200 – Ø300. This causes

overflows of sewerage branches during rains and even floods;

- Some sections are clogged and have low hydraulic conductivity. There are

sections with reverse gradients and broken pipes. The sand-cement mortar

between the concrete pipes does not provide the necessary insulation because it

has cracks.

- There is infiltration of water in the sewerage network which causes over-dilution of

the wastewater.

- Wastewater is discharged directly in gullies and in the Varbitsa River.



For completing the sewerage network of Momchilgrad is necessary to be completed

the sewerage network and to be reconstructed the compromised sections of the

existing network. The construction of a WWTP is pressing. These issues are

addressed in the project: “Reconstruction, modernization and completion of the WSS

network and construction of a UWWTP in the town of Momchilgrad“, which has

received grant funding and the CIW under which will be completed by the end of 2014.

The length of the network envisaged to be rehabilitated and built amounts to 14.79

km.






Momchilgrad Municipality includes 49 settlements of which only one, the municipal

centre the town of Momchilgrad has population over 2,000 PE. There is a ready

project for the WSS infrastructure of the town of Momchilgrad (draft design) which has

been submitted to the investor in May 2011.

In the draft design have been developed two main alternatives for treatment of the

wastewater of Momchilgrad and the one proposed to be designed and implemented in

the next stage is the first option as more efficient.

Wastewater treatment plant of Momchilgrad agglomera tion

Pursuant to the first proposed option the wastewater treatment plant of Momchilgrad

has been designed for an operating period of about 30 years with capacity for 11,268

population equivalent (PE) in 2011 and 10,221 PE in 2041. A water demand rate of

145 l/inh./day has been adopted at present and for the end of the projected period -

2041. The drainage rate has been set to 130 l/inh./day pursuant to the active

“Standards and rules for design of sewerage systems” from 1990.

The receiving body of the treated wastewater will be the Varbitsa River. In the region

after the wastewater outfall the Varbitsa River is of second category pursuant to

Appendix No 3 to Decree No РД-272/03.05.2001 of the Minister of Environment and

Water and is included in the list of sensitive zones pursuant to Decree No РД-

970/28.07.2003 of the Minister of Environment and Water.

The Draft design envisages WWTP-Momchilgrad to be situated on a site envisaged

for this purpose according to project for DRP-CP part of LP No 015042 according to

the MRP of the territory of Momchilgrad. The site is municipal property and has total

area of 11,335 m2 (including 6,139 m2 with mixed purpose of the agricultural land with

Decision No КЗЗ-1 of 24.02.2009 of the MAF and 5,196 m2 for extension of the site).

Table 3-115 presents the specific wastewater quantities according to the adopted first

option of the draft design.

The technological design of WWTP-Momchilgrad adopted according to the first option

includes technological installations for mechanical treatment and biological treatment

in SBR-type aeration tanks with nitrification, denitrification and chemical settling of

phosphorus.

The following technological installations and facilities have been envisaged and

designed for WWTP-Momchilgrad according to the first option of the pre-investment

studies:

1. Technological installation for mechanical treatm ent

• Coarse screen . The inlet wastewater in the WWTP is envisaged to flow

through a coarse screen with bar distance of 30 mm for retaining the bigger

impurities and then goes to the suction reservoir of the wastewater pumping

station equipped with submersible centrifugal pumps.

• Pumping station. The untreated wastewater enters by gravity the treatment

plant. After the coarse screens the designed water quantity will be pumped

(by tow operating and one backup pumps) to the treatment facilities to an

elevation above the terrain in order to avoid higher groundwater and flooding

of the site by river water.

• Fine screen. The fine screen will be of “screw” type with bar openings of 3

mm. The separated hard substances will be compacted in a backwash screw

press and stored in a tank and then disposed to a solid household waste

landfill (SHWL).

• Grit chamber combined with oil separator. One aerated facility for

separation of sand with grain size over 0.2 mm and separation of fats and



other floating impurities is envisaged. The oil and fat separated on the surface

will be concentrated and disposed of in a tank. The sand separated in the grit

chamber will be backwashed and dewatered in a separated classifier and then

disposed from the treatment plant in a tank.

2. Technological installation for biological treatm ent • Sequence batch reactor – SBR . Three facilities have been envisaged in

which will be performed consecutively the processes of nitrification, denitrification, sedimentation and removal of the decanted wastewater and the excess activated sludge as well as chemical removal of the phosphorus.

The chemical settling of the phosphorus will be performed by adding iron trichloride in

the SBRs. The respective reagent installation has been envisaged as well. The total

volume of the 3 SBRs is 3,057 m3. A levelling reservoir with volume of 1,050 m3 has

been envisaged as well.

3. Technological installation for wastewater disinf ection

• Disinfection installation . The disinfection is envisaged to be done with

sodium hypochlorite solution (bleach). The bleach will be stored in plastic

cans (0.5 m3) as a technical product with concentration of 9-10%. The dosing

will be done with a dosing pump. The disinfection installation will operate only

in epidemic situations announced by the RIEW.

• Contact reservoir . The required contact time of the chlorine with the treated

wastewater is 30 minutes. The contact will be established in a reinforced

concrete contact reservoir with volume of 32 m3.

4. Technological installation for sludge treatment

• Gravitational thickener combined with aerobic stabi liser. Two

consecutively operating facilities have been envisaged.

• Sludge dewatering centrifuge . One centrifuge with capacity of 5 m3/h of

supplied sludge quantity has been envisaged with the relevant units for

preparation and dosing of the flocculant and a belt transported for sludge

disposal

Table 3-117 presents information for the expected concentrations of the main

pollutants in the treated wastewater.

5. WWTP - Momchilgrad - Sludge treatment



For the treatment plant of Momchilgrad there is a draft design (DD) which has been

submitted to the investor in May 2011. For the reference year 2011 its capacity has

been designed for 11,268 PE at Qav.day = 1446 m3/d. The technological design

according to the first option includes mechanical and biological treatment in a

sequence batch reactor (SBR) with consecutive cycles of nitrification, denitrification,

sedimentation and removal of the decanted wastewater and the excess activated

sludge as well as chemical removal of the phosphorus.

The wastewater treatment processes generate sludge which must be treated

separately for its final disposal or utilization. Option 1 of the technological design of the

wastewater treatment plant (WWTP) – Momchilgrad along with the wastewater

treatment facilities also includes sludge treatment installations.

The following technological installations and facilities have been envisaged for

wastewater treatment:

1. Mechanical treatment stage

• Coarse screen – separating the biggest impurities in the wastewater with size

exceeding 30 mm;

• Fine screen – separating less dispersed impurities with size exceeding 3 mm

• Grit chamber – separating heavy mineral impurities (sand) and oils.

2. Biological treatment stage

• Sequence batch reactors (SBR) for separating colloid and dissolved organic

substances contain carbon and nitrogen compounds as well as chemically

removed phosphates. The excess activated sludge is removed after the

sedimentation cycle.

3. Wastewater disinfection stage

• Sodium hypochloride disinfection installation

• Contact reservoir

During the wastewater treatment processes under option waste and sludge will be

generated and collected in the following installations:

• Coarse and fine screens – the separated waste will be disposed of in tanks

for disposal from the treatment plant

• Grit chamber – The sand separated in the grit chamber will be backwashed

and dewatered in a separated classifier and then disposed from the treatment

plant in a tank. The separated oils and fats will be disposed of in a tank.

• Sequence batch reactors (SBR) – the excess activated sludge (containing

mainly biodegradable organic substances and a certain amount of phosphates

from the chemical removal of phosphorus) will undergo subsequent treatment

for compacting (significant reduction of their volume by separation of the main

quantity of sludge water), aerobic stabilisation (further decomposition of the

biodegradable organic substances in the biomass) and mechanical



dewatering (further removal of the remaining free water for reduction of the

volume and more economical disposal from the treatment plant).

For the treatment of the excess activated sludge separated from the SBRs in the

technological design of the wastewater treatment plant of Momchilgrad under option 1

have been envisaged the following facilities:

• Aerobic stabilizer combined with a compacter silo – for aerobic

stabilization and gravitational compacting of the sludge up to a humidity of

about 98 %;

• Centrifuge – for dewatering of the sludge up to a humidity of about 75 %

Table 3-118 presents the quantity of waste and sludge expected to be generated in

the future wastewater treatment plant according to data from the draft design and the

expert assessment of the parameters missing in this study.

After the SBRs the excess activated sludge will enter a combined facility – aerobic

stabilizer and compacter silo for compacting up to a humidity of about 97-98 %.

After the stabilized sludge is dewatered in a centrifuge its moisture will be reduced up

to about 75 % (below humidity of 84 % the volume remains almost the same), and its

texture (similar to moist earth) will allow it to be loaded and transported outside of the

treatment plant with minimum costs.

According to data included in the preliminary design the production companies

discharging wastewater in the sewerage network of Momchilgrad are mainly in the

service sector due to which the sludge to be generated at the future treatment plant is

not expected to contain heavy metals and other toxic substances. This makes it

suitable for utilization in the forestry and agriculture.

The arable land on the territory of Momchilgrad Municipality (a total of 13,800 dca)

takes up a relatively small share of its total area but nevertheless a possibility exists

for the utilization of the sludge from the future treatment plant for fertilization of

agricultural areas. In this respect much more promising are the forest territories. They

take up a significant share of the territory belonging to the town and the municipality.



Another alternative which has typically been practiced in our country for a long time is

the disposal of the sludge on solid household waste landfills. A possibility exists the

sludge from the future treatment plant to be disposed at an envisaged disposal site at

the newly designed regional SHW landfill near Kardzhali which will be at about10 km

from Momchilgrad.

Another alternative for utilization of sludge from urban wastewater treatment plants is

to be used for recultivation of damaged terrains for which there is no information on

the territory of Momchilgrad Municipality.

It is recommended in the present regional master plan the sludge from the future

treatment plant of Momchilgrad at first to be disposed of at the local SHW landfill in the

town area until it becomes clear whether the agriculture and forestry are ready to

accept the sludge for utilization and after the relevant administrative procedures are

carried out.

Operation and maintenance of WWTP:

WWTP - Momchilgrad is not built yet. A detailed operating instruction guide is being

drafted for the facility which envisages the mode of operation and management of the

main and auxiliary installations of the plant. The documentation of the operating

equipment contains maintenance instructions for types of planned repairs and the

useful life of the parts breaking most often which should be replaced. Above all the

Energy Engineer of the plant must be familiar in detail with the technology and

specifics of the equipment and the spare parts must be envisaged and delivered on

time. The heart of the plant lies at the command dispatch station where the SCADA

system shall be installed and the regular maintenance of this system will guarantee

the safe and smooth operation of the plant.

- The sewerage network built in the 1960-70’s has expired service life and the pipes

need to be gradually replaced and the branches reconstructed ;

- Insufficient pipe diameters, small depths and unacceptable gradients of the

existing network cause poor operation in some sections of the sewerage network;

- Collapsed wastewater pipes, damaged inspection chambers.

- There is infiltration of water in the sewerage network which causes over-dilution of

the wastewater.

- Untreated wastewater is discharged directly in the Krumovitsa River.

- There is no trunk collector for collecting and disposing the wastewater in the future

WWTP.

The sewerage network has to be completed and the compromised sections of the

According to information provided by the WSS operator in the town of Ardino have

been registered 3 breakdowns on the sewerage network and 4 breakdowns on the

wastewater service connections in 2012.

In 2009 in Ardino was implemented a project “Reconstruction of internal water main

and sewerage network of Zdravets quarter”. As a result of this were reconstructed 606

m of the main collector and was built new separate sewerage network: domestic –

2,708 m and stormwater – 1,327 m.




- The sewerage network built in the 1960-70’s with concrete pipes has expired

service life and needs to be gradually reconstructed.

- The sewerage branches, especially the main collector, have extremely low

hydraulic capacity. The diameters of the pipes are Ø150 and Ø200 and collect

also stormwater. Insufficient depths, unacceptable longitudinal gradients and

overloading during rains seriously hinder the normal functioning of the existing

network and cause problems in some sections of the sewerage network and for

the population in the respective quarters as well.

- Collapsed wastewater pipes, damaged inspection chambers. Due to the influence

of the “soft” groundwater in the region the concrete pipes have become highly

porous and breakable and leak water in both directions, there is serious clogging

– up to 30% and more of the pipes cross section.

- There is infiltrated water in the sewerage network and therefore the wastewater

collected and disposed from the settlements is diluted.

- The wastewater is discharged untreated directly in the Ardinska River, tributary of

the Arda River not far away from the sanitary protection zone of a drinking water

pumping station for the town which is a potential health and environmental threat.

The lack of sewerage network along a significant number of streets leads to soil and

groundwater pollution due to the discharge of wastewater in old and prohibited to be

used absorption pits. Due to the surface draining of the streets during intensive rainfall

part of the properties are flooded and streets become impassable.

According to information provided by the WSS operator in the town of Dzhebel have

been registered no breakdowns on the sewerage network and 3 breakdowns on the

wastewater service connections in 2012


- The sewerage network mostly built more than 35 years ago has expired service

life and highly amortised concrete pipes and especially connections which

damages the impermeability of the system.

- The main collector and the secondary sewerage branches have insufficient

hydraulic conductivity. The pipes with diameter Ø200 and Ø300 are more than

80% of the existing network. The sewerage system has lower design parameters

compared to the currently applicable design standards. Insufficient depths,

unacceptable longitudinal gradients and overloading during rains seriously hinder

the normal functioning of the existing network and cause problems in some

sections of the sewerage network and for the population in the respective quarters

as well.



- Collapsed wastewater pipes, damaged inspection chambers. About 15% of the

inspection chambers in the central part of the town and along the main collector

are clogged. According to information provided by the operator a large number of

breakdowns occur particularly in the central part of the town during intensive

rainfall when the existing combined sewerage system is highly overloaded.

Gradual reconstruction is necessary.

- There is large percentage of infiltrated water in the sewerage network and

therefore the wastewater collected and disposed from the settlements is rather

diluted.

- Part of the sewerage branches and service connections discharge in the gullies

crossing the town without the wastewater reaching the main collector.

- The wastewater is discharged untreated directly in the Dzhebelska River, the

largest tributary of the Varbitsa River.

The lack of sewerage network and the highly amortised existing network cause

uncontrolled soil and groundwater pollution.

During the past 10-15 years a combined sewerage network has been built in stages.

In 2005 the work investment project was updated and sewerage network in the central

part of the village was built – 2,424 m.


- The sewerage network built before 2005 during the years has changed its

purpose and functions. At first the construction began with stormwater collectors

for disposing of the surface run-off from the territory north of road 867 – Zlatograd-

Podkova. Later in these collectors domestic wastewater started to be discharged

which seriously damaged their function. Thus domestic wastewater is discharged

without any control in gullies which flow into the Varbitsa River.

- In the 1970-80’s was built domestic sewerage network of concrete pipes which

served only the public buildings and discharged untreated wastewater in a gully, in

a stormwater drain or in a long non-functioning common cess pit. This existing

domestic sewerage network has expired service life and the concrete pipes are

highly amortised. The sewerage network built before 2005 must be reconstructed.

- Low connection rate of the population to the sewerage network – about 45% and

only inhabitants in the southern part of the village. The lacking sewerage network

causes uncontrolled soil and groundwater pollution.

- The wastewater is discharged untreated directly in the Varbitsa River and

downstream in its terrace are located water abstraction facilities – part of the water

supply systems of Kirkovo, Dzhebel, Momchilgrad.



The sewerage network has to be completed and the existing network must be

reconstructed. A WWTP must be built for achieving the environmental objectives and

requirements.

The generated domestic wastewater of the households in the other settlements are

discharged in own septic tanks as many of them are built as absorption wells which

pursuant to the modern regulations is inacceptable and creates conditions for

environmental pollution. The wastewater from private and public buildings situated

near the rivers and gullies are discharged directly in the water bodies.

Stormwater runs off down the natural slope of the terrains. In some settlements there

are gutters or stormwater drains which take the stormwater to the nearby rivers and

gullies.

SUMMARY OF THE MAIN DEFICIENCIES OF THE WASTEWATER 3.5.8.

INFRASTRUCTURE

Conclusions

Currently all settlements above 2,000 P.E. have sewerage network. However, the

sewerage network is not yet fully constructed in none of the towns - connection rate

ranges from 45% to 97%. Insignificant number of the settlements below 2,000 have

sewerage systems. For those parts which are not yet endowed with a sewer system,

wastewater disposal in old and partly leaking septic tanks is the prevailing solution,

which leads to soil and groundwater pollution and health risk for the population.

Existing sewerage networks function as mixed systems, collecting domestic and

industrial wastewater as well as storm water.



It has been established that the network is in poor condition - mainly due to expired

service life, insufficient hydraulic capacity, low or reverse gradient, poor quality of

construction, damaged and clogged sewers and infiltration. Flooding due to

overflowing sewers during intensive rainfall events occurs in the towns of Kardzhali,

Momchilgrad, Krumovgrad, Ardino, Dzhebel. On-going projects financed under the OP

Environment will increase the connection rate in the towns of Kardzhali and

Momchilgrad up to 100 %.

In the region of ViK OOD Kardzhali teher are no WWTPs built. After completion of on-

going projects the agglomerations of Kardzhali and Momchilgrad will be fully compliant

with the requirements stipulated in the EU Directive 91/271/EEC, while the remaining

4 agglomerations above 2,000 P.E. need substantial improvements to reach full

compliance.

Recommendations:

• Completion of the wastewater network and reconstruction of the damaged

sections as well as the existing sewer sections with insufficient diameters.

• Construction of 4 new WWTPs (apart from the ones with approved financing

under the on-going projects) in: Krumovgrad, Ardino, Dzhebel, Benkovski.

• Updating of network maps and introduction and maintenance of GIS/NIS and

hydraulic models;

• Supply of equipment for sewage maintenance and operation (including CCTV

inspection).

INDUSTRIAL WASTEWATER FACILITIES 3.5.9.


It is important to note that it is particularly difficult to obtain reliable and official data on

industries. As a result, the data provided in this chapter is only partial. The Consultant

specifies that it is impossible to be more specific without making further investigations,

which are not foreseen in the framework of the master plan.

Water in industrial companies is used for drinking, hygienic and technological

purposes. Usually, process water has the largest share. The industry might discharge

wastewater directly into the receiving water (after adequate treatment) or connect to

the urban wastewater network or after the construction of local treatment facilities.

Disposal of wastewater by industrial companies are regulated by the Directives and

Laws relevant to the disposal of hazardous waste and managed according to the

“Polluter Pays” principle, as follows:

• Directive 2000/60/EC of the European Parliament and of the Council of 23

October 2000 establishing a framework for Community action in the field of

Conclusions 3.5.9.3.

The main industrial polluter in the agglomeration of Kardzhali is OCk Kardzhali AD.

The wastewater from the plant pass through a treatment plant which treats it pursuant

to the issued wastewater discharge permission in the water body Studen Kladenets

dam. The plant operation is currently decreasing.

The remaining industries (mainly food industry) discharge wastewater without

treatment in the settlement sewerage networks. Industries associated with potentially

hazardous industrial waste water have not been found or indicated, therefore, it could

be temporarily concluded that there is no risk of dangerous discharges that may exert

a negative effect on the process of WWTP.

Recommendations 3.5.9.4.

Industries may discharge their wastewater directly into the urban sewerage network if

consistent with the statutory requirements of Ordinance No 7 and the approved project

for wastewater treatment plant of Kardzhali.

The Consultant recommends the application of the following measures in order to

improve data availability concerning water supply, sewerage and treatment systems:

• Improvement of mapping for the external water supply systems: Changes in

the system should be timely depicted on maps and plans

• Improvement of mapping for distribution networks of settlements i.e.

digitization of water supply and sewerage network, by indicating diameters

and depths. Introduction of Geographic Information System, using GIS based

software.

• Measurement of water supplied by water sources and to water distribution

networks has to be improved, yearly and monthly water supply should be

metered.

• Collection of additional data on water quality and/or initiating a campaign for

water quality analysis (for priority areas in the feasibility study and for the

other regions included in the terms of reference of the forthcoming technical

assistance contracts.

• Collection of data for yearly, daily and hourly wastewater flow from discharge

points of industrial undertakings in conformity with Ordinance №2 of 8th June

2011 on the issuance of permits for wastewater discharge into water bodies

and determination of individual emission limitations of point sources of

pollution.

• Average (daily mixed sample) and maximum data (from random samples) on

quality of wastewater and quantity in different discharge points, should be

collected.

These measures are included in the long-term investment plan.

Data necessary for completing the assessment of the investment measures

affordability must be collected in shortest terms possible.



3.7. CONCLUSIONS AND RECOMMENDATIONS

WATER RESOURCES 3.7.1.

There are no restrictions on the use of surface water and groundwater for drinking

water supply and other needs, as their determined resources and water quality fully

satisfy the requirements in the relevant legal and statutory documents - the Water

Act, Ordinance № 1/10.10.2007 on groundwater exploration, use and protection,

Ordinance № 2 concerning the protection of waters against pollution caused by

nitrates from agricultural sources, Ordinance № 3/16.10.2000 on the terms and

conditions for investigation, design, approval and operation of sanitary protection

zones around water sources and facilities for drinking water supply as well as around

mineral water sources used for medicinal, preventive, drinking and hygienic purposes,

Ordinance № 9/16.03.2001 on the quality of water intended for drinking and domestic

use, Directive 98/83/EC/concerning the quality of water intended for human

consumption, etc.

WATER POLLUTION 3.7.2.

The conclusions from the performed studies, reviews, analyses and assessment of the

information related to the water pollution conditions in the designated territory served

by ViK OOD Kardzhali for undertaking investment measures for improving water

quality are as follows:

• At present the main polluters of water bodies with organic and biogenic

elements are the pollution loads of population and industrial companies of the

settlements which discharge wastewater in the water bodies.

• Water bodies are polluted also by certain industrial emitters which discharge

their wastewater into the water bodies without the necessary treatment

• Settlements and other separate facilities without sewerage network pollute

the soils and groundwater.

• Infiltration of polluted wastewater from existing illegal landfills subject to

closing also pollutes soils and groundwater.

Investment programmes for construction of WWTPs in separate agglomerations are

envisaged which will eliminate the conditions creating health risk to the population in

the area and environmental risk. The utility company ViK OOD Kardzhali must

negotiate the conditions for including wastewater from the industries into the sewerage

networks of settlements pursuant to Ordinance No 7 and the developed designs in the

WWTP projects for each agglomeration.



CURRENT WATER CONSUMPTION 3.7.3.

Conclusions

The two major problems with water consumption are as follows:

• Water metering

Inaccurate metering of the water consumed. (Water metering is accurate enough

when it comes to large industrial and public consumers due to the fact that water

meters are checked following a schedule as well as in case of the slightest doubt

about existing imprecision.) If necessary, those water meters are replaced. Problems

concerning consumption metering are mainly typical of small users, consuming water

for domestic purposes.

• Water thefts

Water is stolen though illegal service or other connections.

For „ViK” OOD Kardzhali the commercial losses along with the unbilled legal

consumption which is note metered are estimated to 10 % of the quantity supplied by

the water sources.

It is obvious that along with the real losses the losses from water non-billed but

consumed for different purposes is a serious problem.

Recommendations

• Installation of water meters before and after pressure reservoirs, serving the

settlements.

• We recommend more frequent verifications and replacement of water meters

of small domestic and commercial consumers. It is necessary to carry out the

inspections included in the schedule.

• Focused efforts are required to achieve accurate metering of water delivered

and consumed – from water sources to all users. This is of great importance

so that at any moment the Operator could have precise information about the

condition of the relevant water supply system.

• Fight against water thefts is difficult as illegal water supply connections are not

easy to detect. Unauthorised connections will be possible to localise, provided

that all old water supply sections made of asbestos cement or steel pipes are

replaced.

WATER SUPPLY INFRASTRUCTURE 3.7.4.

Water supply systems 3.7.4.1.

Conclusions

Water sources

Some water source have no water use permissions



Maintaining the SPZ is difficult – the fences and information signs have been placed

repeatedly and then stolen. Their absence results in sanctions for the Operator

imposed by the RIEW.

Water treatment

On the territory of ViK OOD- Kardzhali there is only one DWTP. The quality of the

treated water from Borovitsa dam in complies with the requirements of Ordinance №9.

The water sources utilized by the WSS operator have good quality and comply with

the regulatory requirements. The only treatment of the water not treated at Enchets

DWTP is disinfection. However the quantity of residual chlorine is not monitored

automatically and the disinfectant dosage is not measured accordingly.

The chlorine disinfection facilities do not comply with the safety requirements and

present danger to the life and health of the operating staff.

Reservoirs

Many of the reservoirs were built in the period 1940- 1980 but there are also some

built and commissioned after 2000.

Structurally all reservoirs operated by ViK Kardzhali OOD are in satisfactory

condition – there are no visible leaks from the water chambers, some damaged

plastering and deformed external stairs have been observed.

Regardless of the constant maintenance by the operator – cleaning of corroded pipes

and painting, the pipe connections and the fixtures are in bad condition.

There are reservoirs which are not used for one or other reason.

The SPZ of some reservoirs are damaged, there are no fences, reliable doors and

information signs.

Pumping stations

The condition of the buildings is satisfactory. The following problems have been

observed – compromised roof structures, leaks, cracks, damaged plastering,

damaged flooring, corroded metal parts – rails, staircases, frames, etc.

Some of the installed pumps are old – over 25 years. They are characterized with low

efficiency and high energy consumption. Spare parts are missing.

Some suction reservoirs are in poor operational condition.

Water mains

The external water mains of the systems are 93.06 km – steel, asbestos cement,

reinforced concrete – built in the period of 1930-1980. Small part of the water mains

are built of modern materials and laid after 1998 and these are in good technical

condition as 25% are asbestos cement, 69% steel, 6% modern materials, etc. most of

the pipes are old and amortised.

- The main problem of the steel pipes is corrosion. Rarely leaks are observed

due to poor quality of welding.



- For reinforced concrete pressure pipes the main deficiency is the insufficiently

compacted concrete of the pipes due to which leaks and corrosion on the

steel reinforcement appear.

- The main problems of the AC water mains are the compromised connections

(worn-out gaskets), broken and cracked pipes, deformations.

- The water mains are in poor condition and are a potential source of problems.

The leaks from compromised connections, the corroded and deformed pipes

generate high water losses.

The operator has decommissioned problematic water mains generating frequent

breakdowns and water losses until providing the financial means for replacing those

water mains.

The bad condition of the trunk water mains creates risks of drinking water shortage for

the population and deterioration of the quality parameters of the water.

The facilities on these water mains – relief chambers, collection chambers, air-

chambers and draining chambers are also in poor condition and need overall

renovation – structural and replacement of fixtures and equipment.

The trunk water mains have no easement zones established.

Recommendations

Water sources

Undertaking actions for updating the water use permissions of all working water

sources.

Rehabilitation of the sanitary protection zones in three belts the borders of which are

determined under Ordinance № 3/16.10.2000 on the terms and conditions for

investigation, design, approval and operation of sanitary protection zones around

water sources and facilities for drinking water supply as well as around mineral water

sources used for medicinal, preventive, drinking and hygienic purposes.

Metering devices must be installed or replaced at all water sources.

Water treatment

Rehabilitation of the disinfection systems in all points where disinfectant is supplied.

The systems must be equipped with automatic cycles for monitoring the quantity of

residual chlorine in the water and automatic precise measuring of the disinfectant

dosage according to the quantity of residual chlorine in the water. All chlorination

compartments working with chlorine gas must be equipped with automatic chlorine

deactivation system, in case of eventual leaks from chlorine supply system or leaks

from the storage tanks.

Metering devices must be installed at the outlet of each DWTP.

Reservoirs



The rehabilitation should include renovation of the reservoirs – restoring damaged

plastering, rails, doors and stairs in the reservoirs, restoring the fences of the SPZ –

belt I.

Gradual replacement of all pipe connections and fixtures.

Where metering devices exists they need to be calibrated or replaced if necessary.

Metering devices must be installed at the outlets of all reservoirs.

Reservoirs which are not used must be made safe.

In settlements where the existing reservoirs have no sufficient capacity the

construction of new ones must be planned for providing sufficient regulating, fire-

fighting and emergency storage volume.

Pumping stations

Rehabilitation of the operating pumping stations /starting with the most pressing

repairs/ – rehabilitation of roof structures and covers and other parts disrupting the

operation of the pumping stations.

Gradual replacement of the inefficient equipment of the pumping stations – pumps,

engines and amortised pipe connections, fixtures, metering devices, automatisation.

PS which are not used must be made safe.

Water mains

We recommend the gradual replacement of the trunk water mains to start as early as

the first programme period 2014 - 2020 in order to avoid the risk of water shortage.

Sections must be repaired following a priority based on the condition of the water

mains, the affected population and the lack of alternative water supply.

Updating the cadastre, implementation and maintenance of GIS and hydraulic

modelling of the water supply systems;

For providing the water supply to settlements where supply is limited it must be

considered to connect these to a centralized water supply network or provide supply

from local water source which can provide the additional water quantities necessary.

Distribution water networks 3.7.4.2.

Conclusions:

The water distribution networks in the settlements which are served by ViK Kardzhali”

OOD-Kardzhali are in overall poor condition and some are in exceptionally bad

condition. The water main pipes /main and secondary branches and service

connections/ in the settlements with over 2,000 inhabitants are over 80 % built of

asbestos cement and steel with galvanized steel service connections. The service life

of the mains has expired long ago, the pipes are highly corroded, with compromised

connections which causes frequent breakdowns and high water losses. Real losses in

the distribution networks are significant and at some places reach 60 % of the total

input water quantity of the distribution network.



The network equipment is in the same critical condition. The stop valves and fire

hydrants are insufficient and the existing ones are amortised and in bad operating

condition.

Metering devices are in unsatisfactory condition and missing at some places. Water

meters must be calibrated regularly (every 5 years). A large share of the installed

water meters are over 10-years old.

Recommendations:

An overall replacement of the amortised asbestos cement and steel pipes of the main

and secondary water distribution branches and service connections is necessary. This

replacement will help detect the illegal consumers connected to the network. The

financial calculations recommend gradual replacement as the main branches and the

ones with the most breakdowns during the years will have priority. Where sewerage

network is built it must be envisaged also mandatory rehabilitation of the internal water

main network and service connections. Materials with good operating parameters

must be used – high density polyethylene, cast iron or fibre glass.

Along with the pipe replacement must also be replaced the stop valves and fire

hydrants.

The metering devices which are over 10 years old must be replaced especially those

of domestic consumers and their regular inspection at 5 years must continue.

WASTEWATER INFRASTRUCTURE 3.7.5.

Conclusions:

Currently all settlements with population over 2,000 PE have sewerage networks.

Nevertheless it is not completely constructed in neither of the towns (the connection

rate varies between 45% and 97 %), and the settlements below 2,000 PE with small

exceptions, have no sewerage systems

It has been established that a substantial part of the network is in bad condition. In

some agglomerations have been reported floods during rainfall due to overloaded

sewerage sections which have insufficient hydraulic conductivity. The on-going

projects funded under OP Environment will increase the connection rate up to 100 %

in the towns of Kardzhali and Momchilgrad.

There are no WWTPs built in the designated territory of “ViK” OOD- Kardzhali. After

the completion of the on-going projects 2 of the 6 agglomerations – Kardzhali and

Momchilgrad, will comply fully with the requirements set in Directive 91/271/ЕЕС.

In the future the sludge must be temporarily disposed of at the regional landfill in

Kardzhali until their quality is examined. Since the sludge quality is expected to be

good their sustainable utilization must be examined.

The main industrial polluter in Kardzhali is the Lead and Zinc Processing Plant. It has its own WWTP. The plant has discharge permission pursuant to Ordinance No 2/08.06.2011 (Directive for complex prevention and pollution control). Its operation is slowing down and tends to cease entirely. The other industrial companies (mainly from



the food processing industry) discharge their wastewater (10 to 20% of the total wastewater quantity) untreated in the municipal WWTP.

Recommendations:

• Expansion and reconstruction of the sewerage network.

• Construction of 6 new WWTP.

• Updating the network information systems.

• Supply of equipment for maintenance and operation of the sewerage network

• Developing an overall strategy for sludge management in compliance with the European directives for sludge and solid waste.

• Construction of facilities for preliminary treatment in all industrial companies with wastewater polluted above the permissible levels discharged in the urban sewerage system.

3.8. ON-GOING AND PENDING PROJECTS

Several equipment or infrastructure improvement projects have been conducted lately by different organizations out of the framework of the present Master Plan. Once identified, these projects are considered in different ways:

• Completed projects to date are included in the existing situation;

• On-going projects (projects that were approved and financed but not completed to date) are also included in the existing situation. In fact, corresponding assets are considered as existing, investment costs are not included within the Master Plan but future operation and maintenance costs are included for the macro-affordability assessment.

• Projects not approved to date, but the purpose of which are in line with the Master Plan objectives, are included in the Master Plan. Corresponding design, investment costs and timeframes are newly assessed according to the Consultant’s methodology.

• Other projects, which are not in line with the objectives and criteria of the Master Plan, are either not included or substantially altered.

For the Regional Master Plan of the designated territory of ViK OOD-Kardzhali, all non-completed projects were either considered as on-going (and thus their costs were not included in the Investment Programme) or considered appropriate and included in the Master Plan. The initial designs were also kept.

4. PRIORITIES FOR THE DEVELOPMENT OF THE WATER AND WASTEWATER INFRASTRUCTURE TO ACHIEVE COMPLIANCE WITH EU DIRECTIVES AND ENVIRONMENTAL ACQUIS

4.1. METHODOLOGY AND ASSUMPTIONS

BASIC DESIGN CRITERIA 4.1.1.

Reference periods for investment 4.1.1.1.

programmes

Investment program periods are set as follows9:

o Short-term: 2014 – 2020;

o Medium term: 2021 – 2028;

o Long term: 2029 – 2038.

In addition to the above mentioned key dates for the investment programming periods,

the Consultant defined the following dates and terms:

o Existing situation : Average of data from 2009 to 2011; Infrastructure which

has been put into operation until the end of 2011 has been taken into account;

o Situation after implementation of on-going projects : All on-going projects

will not be included in the Master Plans’ investment programme, but

respective data are presented separately in Chapter 3. The impact of these

investment projects with completion dates between 2012 and 2016 will be

taken into consideration in the year 2016 (first year of projection);

o 2016: First year of operation of infrastructure proposed in the Short-term

investment programme.

Population forecast criteria 4.1.1.2.

Population forecast takes into account:

o NSI population forecasts up to the year 2060, with starting level corresponding

to 2011 census data;

o Population is forecasted based on population dynamics: birth rate, death rate

and net migration (mechanical growth);

o Birth rate and death rate are forecasted with conventional methods. A trend is

established and a constant coefficient or a steady increase/decrease over the

years is applied. This approach takes into account the population specifics of

each municipality and settlement.

9 In agreement with MRDPW the program periods deviate from those defined in the ToR in

order to ensure consistency with the operational programming period.



The forecast for each subsequent year is obtained from the population of the previous

year, by adding births and subtracting deaths and net migration. In practical terms:

Population for

the forecasted

year

= Population for the

year before + Births - Deaths +

Net

migration

The population forecast for the region are presented in Chapter 5.1 related to socio-

economic projections.

Water supply systems 4.1.1.3.

This section develops the design criteria which were used for defining and designing

the proposed infrastructures for water supply systems.

At master plan level only basic design criteria have been taken into consideration,

while more detailed criteria will be developed in the subsequent feasibility studies.

4.1.1.3.1. Water demand forecast and design flows

The “effective water demand” is the quantity of water demanded of a given quality at a

specified price. The analysis of demand for water, including realistically forecasted

future levels of demand, is an important and critical step in the realization of a Master

Plan, for both water supply and sewer systems. This section presents the

methodology for assessing the evolution of water demand from present situation till

the design horizon. This methodology is based on the water balance defined by the

IWA and synthesized in the following table.

The Water Demand includes the following components:

o Revenue water , including:



• Invoiced exported water;

• Invoiced domestic consumption;

• Invoiced industrial consumption;

• Invoiced commercial and institutional consumption.

o Non-Revenue Water (NRW), including:

• Uninvoiced water (cleaning of the streets, public parks watering, fire

service...);

• Apparent losses such as illegal consumptions and accuracy errors of the

water meters;

• Real losses which correspond to pipe leaks.

Unrealistic projections could lead to inadequate priority and long-term investment

programs in terms of sizing of the facilities and can have serious consequences on the

functioning of water supply systems (insufficient/excessive pressures, dysfunction of

pumping stations and reservoirs, excessive residence time and low water quality...).

Numerous factors can directly or indirectly influence water demand. They are

synthesized in the following diagram.

Figure 4-1 Factors influencing water demand

Domestic consumption

o Connection rate and population served

The connection rate to water supply system is determined through the following

principles:

• For year 2011, this rate is the present rate provided by the ViKs;



• For year 2021 and the following years, this rate is set to 100%;

• For year 2016, this rate is assessed by taking into account the current

situation and the on-going projects which will impact this rate (extension of

water supply systems…).

The population served is then deducted by multiplying the total population assessed

on the considered date by the connection rate assessed on the same date.

o Domestic per capita consumption

• Calculation of present permanent consumption per capita:

The present domestic consumption in 2011 is the average domestic consumption from

2009 till 2011 provided by the ViKs. The consumption per capita can then be deducted

from the previous value and from the official population data (census 2011).

It was noticed that for some of the settlements in the study area, this specific

consumption per capita per day reaches a very high level, up to 400 l/c/d and even

more. Additional investigations showed that these high rates are due to seasonal

factors, such as temporary agricultural works (grape harvest…), temporary population

having holiday homes... This temporary population not being accounted in the

population statistics from the census, the Consortium proposes the following

methodology:

� Calculation of consumption per capita based on average domestic

consumption from 2009 to 2011 and corresponding population data from the

same year;

� Identification of settlements affected by temporary consumption

(settlements with consumption per capita above 120 l/c/d );

� For settlements not concerned with such temporary consumption, calculation

of the permanent consumption per capita by averaging data from 2009 to

2011 (temporary consumption being null in this case);

� For settlements affected by temporary domestic consumption, permanent

consumption per capita is set to 120 l/c/d , the rest of the consumption

being considered as temporary consumption10.

• Calculation of permanent consumption per capita in 2038:

The permanent consumption per capita is set to 120 l/c/d (11)

• Calculation of the permanent consumption per capita for intermediate reference

dates (2016, 2021 and 2028):

Consumption per capita is assessed based on a linear interpolation between present

and 2038 values.

10 Example: Small village with consumption per capita (average from 2009 to 2011) equal to

220 l/day/inh., with 500 inhabitants. Then, the permanent consumption per capita will be

assumed to be 120 l/day/inh. and the rest, e.g. 100 l/day/inh. x 500 = 50 m3/day will be

considered as temporary domestic consumption.

11 According to Ordinance N°2 from March 2005 for “Des ign, construction and exploitation of

water supply systems”, see Appendix N°1.



Note: Regarding the Macro-Affordability Model for the assessment of the proposed

investment programmes, the affordability criterion is that the monthly water bill should

not exceed 4% of the average monthly household income at a consumption level of

2.8 m3 per person per month (93.3 l/capita/day)(12).

o Average domestic consumption

It is proposed to assess the average domestic consumption as follows for each of the

reference dates:

• Calculation of the present domestic consumption: � Calculation of the permanent domestic consumption by multiplying

the consumption per capita on the considered date by the total

population served on the same date;

� For settlements affected by temporary domestic consumption,

calculation of temporary domestic consumption based on the

difference between average domestic consumption from 2009 to 2011

and previous permanent domestic consumption.

• Calculation of the domestic consumption in 2038: The main assumption is

that in 2038, all households will get house connection and reach the

reference per capita domestic consumption:

� Calculation of permanent domestic consumption based on

consumption per capita of 120 l /c/d(13) and permanent population

forecast in 2038;

� Calculation of temporary domestic consumption on the basis of

present assessed value and socio-economic forecast.

• Calculation of the permanent and temporary domestic consumptions for

intermediate reference dates (2016, 2021 and 2028) based on a linear

interpolation between present and 2038 values.

o Daily peak coefficient and domestic consumption

The daily peak consumption is assessed by multiplying the daily peak coefficient (5)

(see appendix 4-1) and the average domestic consumption.

o Hourly peak coefficient and domestic consumption

The hourly peak consumption is assessed by multiplying the hourly peak coefficient

(see appendix 4-1) and the daily peak domestic consumption.

Non-domestic consumption

It is proposed to apply the following principles:

o Categories: the non-domestic consumption is divided into three categories:

• Public facilities;

• Industrial;

• Agricultural.

12 According to the Terms of Reference, Art. 6.2 Macro-Affordability Assessment.

13 According to Ordinance N°2 from March 2005 for “Des ign, construction and exploitation of

water supply systems”, see Appendix N°1.



o Calculation of non-domestic consumption in 2011:

• If the information for 2011 is known, the non-domestic water demand for

subsequent reference years is obtained by linear extrapolation, applying the

following two rates:

� Projected economic growth (based on data from International Institutions

like the World Bank, the International Monetary Fund and Economist

Intelligence Unit);

� 1% of annual decrease of the initial consumption, as a consequence of a

water savings policy for businesses and public institutions.

• If the information is unknown for the year 2011, the non-domestic water

demand for subsequent reference years is assessed accordingly with the

following principles:

� For settlements with less than 2,000 inhabitants in 2011, the unit

consumption will be 12 litres/capita/day (10% of the target consumption

per capita), from which the non-domestic water demand is deducted by

multiplying this unit consumption by the estimated population of the

reference year for which it is calculated;

� For settlements with more than 2,000 inhabitants in 2011, the unit

consumption will be 40 litres/capita/day (14)(15), from which the non-

domestic water demand is deducted by multiplying this unit consumption

by the estimated population of the reference year for which it is

calculated.

Non-Revenue Water

Non-Revenue Water (NRW) is the sum of:

o Unbilled authorized consumption;

o Apparent losses (unauthorised consumption and customer metering

inaccuracies);

o Real losses (leakages).

Water losses are the sum of apparent losses and real losses. At the Master Plan

stage, the repartition between these two types of losses cannot be estimated.

The commercial losses should be reduced through targeted rehabilitation programs

which are defined in the Master Plan as well as through specific NRW Reduction

programs to be implemented by water supply and sewerage companies before the

reference year 2021.

In order to asses NRW on the reference dates, the following criteria are used:

o In the case of a new or rebuilt water supply network, the NRW Rate will be as

follows:

• 2011: 0% (non-existent network);

14 In conformity with Ordinance N°2 from March 2005 for “Design, construction and exploitation

of water supply systems”, Art 17.7, §(2). See Appendix N°1.

15 In conformity with the Operational Programme Environment 2007 – 2013, Requirements for

preparation of investment projects in agglomerations of between 2,000 and 10,000 PE.



• 2016: 15% (new network);

• 2021 and 2028: linear interpolation between the values for 2016 and 2038;

• 2038: 20 %.

o In the case of an existing water supply network, the NRW Rate will be as

follows:

• 2011: present value provided by the ViKs and based on water loss

monitoring data (assessment based on water loss measurements carried out

by the VIK);

• 2016, 2021 and 2028.

� If no particular rehabilitation program is defined in the Master Plan, linear

interpolation between the values for 2011 and 2038, in relation with the

NRW reduction program to be implemented by the ViK.

� If specific rehabilitation program is defined, calculation of the NRW rate at

the date of rehabilitation based on 15% NRW rate for the rehabilitated

network and linear interpolation between the values for 2011 and 2038

for the rest of the network. • 2038: 25% (target for an existing network in operation)(16);

• Particular case: if, when calculated by linear interpolation, the NRW rate for

the reference year 2021 exceeds 35%, it is set at 35% for 2021 and the

value for 2016 is assessed through interpolation between present and 2021

values. The NRW rate for the reference year 2028 is subsequently set to

32%.

Note: Obviously, the reduction of NRW Rate is closely linked to the NRW reduction

programs implemented by the various ViKs. In fact, the NRW reduction programmes

to be implemented are designed so that the above-mentioned objectives are met.

Summary – Water supply component

The methodology for water demand forecast is summarized hereafter: �� = (PresentorforecastedPopulation) × (Connectionrate)

�� =(PresentorforecastedPopulation) × (PresentorforecastedConsumptionpercapitaperday) +(Presentorforecastedtemporaryconsumption)

�� = �Presentorforecastedvalueifknownor, ifunknown:Population × 12LPCDifPopulation < 2000��ℎ.Population × 40LPCDifPopulation > 2000��ℎ.

�� = (DomesticWaterConsumption) + (NonDomesticWaterConsumption)

��− �� = (Presentorforecastedwaterconsumption)(1 − PresentorforecastedNRWRate)

16 To maintain conformity with European Standards, the objective of 20% is kept but for a year

beyond 2038.

In case of high nitrate concentrations in raw water, three approaches are possible, as

summarized below (in order of application priority):

• Dismissal of the resource, applicable only if other resource are available or a

connection to other water systems is possible

• Blend the contaminated resource to quality compliant resources, in order to

obtain an acceptable nitrate concentration, applicable only if other resources

are available, upstream from the distribution to the serviced settlement

• Treatment in a nitrate removal plant:

o Chemical treatment with ion exchange resins, which is the preferred

treatment, particularly in rural areas (least costly option)

o Biological treatment, only in case of important design flow (costly

option)

o Technical Description of disinfection processes

The treatment will depend on the quality and length of the network.

The following table summarizes the arguments for the different disinfection processes

and gives a qualitative evaluation for the operation under general conditions.

o Operational criteria

In order to guarantee an error-free function of the Water Treatment Plants, operational

aspects have to be considered for the different technical options, which have been

described above.



A simple and comprehensive operation shall ensure that:

• the personnel can be trained quickly in operation and maintenance;

• the staff could intervene quickly in case of an emergency;

• the staff is able to identify operation problems early.

Furthermore, an operation concept shall assure that:

• the technical requirements concerning effluent standards can be met

permanently;

• the plant is operated economically;

• a maximum of accident prevention is foreseen.

If these precautions are not taken, any malfunction of a water treatment plant can

cause a sanitary damage (diseases) for humans. This damage can cause legal

actions such as claim of compensation.

Storage facilities

The dimensioning of the storage is made according to Ordinance N°2 from March

2005 for “Design, construction and exploitation of water supply systems” .

Network

According to Ordinance N°2 from March 2005 for “Des ign, construction and

exploitation of water supply systems”, several parameters were taken into account for

the dimensioning of the network .

Pumping stations

According to Ordinance N°2 from March 2005 for “Des ign, construction and

exploitation of water supply systems”, several parameters were taken into account for

the dimensioning of the network (.

Sewerage systems 4.1.1.4.

This section develops the design criteria, which were used for defining and designing

the proposed infrastructures for sewerage systems.

4.1.1.4.1. Dry weather discharges and pollution loads

The dry weather flows include the following components:

o Sanitary flows, generated by domestic and non-domestic customers;

o Ground Water Infiltration (GWI) flows, generated by the drainage of ground

water through the sewerage network;

o Runoff flows, generated by rainfall events in combined sewer systems.

The dry weather wastewater flows are determined by:

o The drainage factor of consumed water (proportion of water demand discharged

into the sewerage network);

o The groundwater infiltration rate;



o The connection rate (proportion of water users connected to the sewerage

network).

o The network characteristics (combined or separated)

Unrealistic projections could lead to inadequate priority and long-term investment

programs in terms of sizing of the facilities and can have serious consequences on the

functioning of sewer systems (overflows occurring in Dry Weather Flow conditions,

overloading of the network and of the treatment facilities...).

Connection rate and connected population

The connection rate to sewerage system is determined as follows:

o For year 2011, this rate is the present rate provided by the ViKs;

o For settlements with over 2,000 inhabitants:

• For the reference years 2016 and 2021 the rate is set to 90% (or the 2011

rate if it is more important than 90%);

• For the following years, the rate ranges from 90 to 100% depending on the

proposed investment programmes.

o For the settlements with less than 2,000 inhabitants (17):

• For the reference year 2028, an intermediate value is determined depending

on the proposed investment programmes;

• For the reference year 2038, the rate is set, as a minimum, to 90%;

o Particular case: if a settlement is already connected (or if there is an existing

project for its connection) to a city of over 2,000 inhabitants, the connection rate

is set, as a minimum, to 90% for the reference year 2028. For the other

reference years, an intermediate value is determined based on the investment

programmes to be proposed.

The connected population is then deducted by multiplying the total population

assessed on the considered date by the connection rate assessed on the same date.

Domestic Wastewater discharges

o Wastewater generation factor and discharge rate

The wastewater generation factor, which corresponds to the ratio between wastewater

discharge and water consumption, is considered to be constant equal to 0.9 (18).

The wastewater discharge rate, which corresponds to the average daily wastewater

discharge per capita and per day, is assessed for each reference date by multiplying

the consumption per capita by the wastewater generation factor.

�� = (Consumptionpercapita) × (wastewatergenerationfactor) o Average domestic wastewater discharge

17 According to the Terms of Reference and according to the European Directive 91/271/EEC,

settlements below 2,000 PE should be included in this study.

18 According to the Terms of Reference, Art. 5.1 Proposal of Basic Design Criteria, and

according to the effective Standards for design of sewerage systems of 1989, Art. 33



It is proposed to assess the average permanent domestic wastewater discharge as

follows according to the Bulgarian norms (19), by multiplying the wastewater discharge

rate on the considered reference date by the total connected population on the same

date:

Q��,� =N × a

1000

Where:

• Qav,d is the daily average wastewater flow in m3 per day

• N is the connected population on the reference date

• a is the wastewater discharge rate in l/c/d

Moreover, for settlements affected by temporary domestic consumption, the

temporary domestic wastewater discharge is assessed by multiplying the

temporary domestic consumption (on the considered date) by the wastewater

generation factor and the connection rate.

DomesticWastewaterdischarge = �Wastewaterdischargerate�× �Population�+ �temporarydomesticconsumption�×�wastewatergenerationfactor�!× �WastewaterConnectionRate� o Common unevenness peak coefficient and hourly peak wastewater discharges

Common unevenness peak coefficient for sewerage systems is set as follows, in

accordance with Bulgarian norms (20): Q��,� = Q��,� × K��,�

Where:

• Qmax,h is the maximum hourly wastewater flow, in m3 per day

• Qav,d is the daily average wastewater flow in m3 per day

• К0 max,h is the coefficient for common unevenness, calculated as

follows:

K��,� = 1 +2.5

Q��,��.

Non-domestic wastewater discharges

Non-domestic wastewater discharge, comprising discharges from industries as well as

public-servicing buildings, is assessed based on:

o Non-domestic water consumption, comprising consumption from industries and

public-servicing buildings;

o Connection rate of the non-domestic consumers to the sewerage system;

19 Bulgarian Norms for design of sewerage systems, issued in 1990

20 Bulgarian Norms for design of sewerage systems, issued in 1990, Chapter 3, Part 1,

Article 34



o Wastewater discharges from customers that have their own water supply

resource and are connected to the sewerage network;

o Wastewater generation factor;

o The average time of activity of the considered customer.

NonDomesticWastewaterDischarge = [(NonDomesticWaterConsumption) × (Non −domesticconnectionrate) + (WaterVolumesfromownresource)] ×(Wastewatergenerationfactor) × (Averagedailyactivitytime)/24

Groundwater and leakage infiltration discharge

Concerning the permanent groundwater and leakage infiltration discharge in sewerage

networks, in dry weather conditions, we propose to implement the following

methodology in accordance with the requirements for the preparation of investment

projects under priority axis 1 of OPE (Operational Programme – Environment 2007 -

2013) approved by the Minister Nona Karadzhova on 30.06.2010 (page 20):

o In case of available measurements and detailed study regarding the studied

sewerage system, it is proposed to take into account the results of the study

regarding the infiltration discharges to take into account for present situation

and to project it for reference dates based on the evolution of the area of the

catchment area;

o In case no such study is available, the methodology defined in the German

technical guidance – Document ATV/DWA – A128e is applied, e.g.

• Infiltration water are related to the total sewerage catchment area AC,s.

• The infiltration discharge in dry weather conditions is determined as follows

using a location-specific infiltration discharge rate qiw: "� = #� ∙ $�,

Where:

• qiw corresponds to the infiltration water discharge rate in dry weather

condition, which should be between 0.05 and 0.15 l/s/ha, depending on the

state of the sewerage network and the level of leakages in the water supply

system.

• AC,s corresponds to the area covered by the sewerage system

Pollution loads

In accordance with the Terms of Reference, the rates of pollution loads of domestic

wastewater are set as follows:

o BOD5 : 60 g/person/day;

o Suspended Solids : 70 g/person/day;

o Total Nitrogen : 11 g/person/day;

o Total Phosphorus : 2 g/person/day;

o COD: 120 g/person/day.

Pollutant concentrations of non-domestic wastewater will be based on Appendix 2 of

"Ordinance N°7 of November 14, 2000, for Conditions and order for discharge of

industrial waste waters in sewerage systems of settlements. Concerning hazardous



contents, maximum permissible concentrations are based on Ordinance N°6 of

November 9, 2000 on emission standards for levels of dangerous substances in

wastewater discharged into water bodies.

Default values are set based on the intermediate values proposed by the State Energy

and Water Regulatory Commission, as of 31.12.2012 (II degree in the table below).

Concerning BOD5, the extreme values admissible is between 25 mg/l (in accordance

with I degree below), and 400 mg/l (in accordance with Ordinance n°7).

These values may be modified in the case of an apparent particular context, after

justification by an analysis of the existing situation in the settlement.

Wastewater quality

It has to be noted that the wastewater quality needs to be assessed more in depth at

the Feasibility Study stage.

4.1.1.4.2. Stormwater discharges

Separate sewerage systems

In the case of separate sewerage systems, there is always a part of unavoidable

stormwater run-off entering the sewerage system, in relation with improper customer

connections (internal stormwater networks connected to the public wastewater

network) and other factors such as infiltration from the manhole covers…

In order to assess these unavoidable run-off flows, it is proposed to implement the

methodology detailed hereafter, compliant with Bulgarian Norms for design of

sewerage systems, issued in 1990:

o In case of available measurements and detailed study regarding the studied

separate sewerage system, it is proposed to take into account the results of the

study regarding the run-off flows in stormy weather conditions to take into

account for present situation;

o In case no such study is available, it is considered that the amount of

stormwater discharge, together with the groundwater infiltration into the

sewerage system, is equal to the hourly peak wastewater discharge:

Q�� = Q��,� × K��,�

Combined sewerage systems

In that case, stormwater flow is a normal component of the total discharge in the

sewers and is defined according to the rational method, in accordance with Bulgarian

Norms for design of sewerage systems, issued in 1990 .



4.1.1.4.3. Synthesis of the design flows for sewerage systems

Based on the previous methodology, the following formula should be used in order to

determine the design flow for the elements of the separate sewer systems (gravity

collectors, pumping stations, pressure pipes…):

Q�� = 2 ∙ Q��,� ∙ K��,� + "��,�,�� !

Regarding the combined sewer systems, the following formula should be used in order

to determine the design flow for the elements of the system (gravity collectors,

pumping stations, pressure pipes, storm overflows…):

Q�� = Q��,� ∙ K��,� + "��,�,�� ! + "� + ""#

4.1.1.4.4. Technical design criteria

Gravity collectors

For gravity sewerage systems, two different systems can be implemented. While

combined sewer systems are designed to convey both wastewater and stormwater

flows, separate systems are designed in order to convey separately wastewater and

stormwater flows through different networks. For new networks, separate systems will

o Technical and Environmental Criteria

Within the present Master Plan, the environmental criteria required by the European

Union and the Government of Bulgaria have to be met for all agglomerations with a

population equivalent of more than 2,000.



Due to high risk of eutrophication and the risk of high concentrations of nitrates in

surface waters jeopardizing the quality of drinking water in the region, the territory of

Bulgaria has been classified as Sensitive Area. Technically the current law requires

the implementation of advanced treatment considering the additional removal of

nitrate and phosphorus for agglomerations with a population equivalent of more than

10,000.

o Technical Description of treatment processes

Treatment processes will depend on the inlet load which can be translated by

Population Equivalent (P.E.):

o Operational Criteria

In order to guarantee an error-free function of the Wastewater Treatment Plants,

operational aspects have to be considered for the different technical options which

have been described above.

A simple and comprehensive operation shall ensure that:

• the personnel can be trained quickly in operation and maintenance;

• the staff could intervene quickly in case of an emergency;

• the staff is able to identify operation problems early.

Furthermore, an operation concept shall assure that:

• the technical requirements concerning effluent standards can be met

permanently;

• the plant is operated economically;

• a maximum of accident prevention is foreseen.

If these precautions are not taken, any malfunction of a wastewater treatment plant

can cause a substantial environmental damage (fish dying or eutrophication) in the

receiving water bodies. This damage can cause legal actions such as claim of

compensation. It is furthermore to be considered that biological processes, which

usually form the basis of appropriate municipal wastewater treatment options, need a

relatively long time to overcome breakdowns and to regain full treatment capacity.

Wastewater Sludge treatment

o Technical and Environmental Criteria

To choose the right sludge treatment, it is important to know the final destination of the

sludge. For example, if there are industries in the area, heavy metals are expected to

be found in the sludge. Sludge should be sent in land disposal.

If there are no major industries in the area, no heavy metals are expected to be found

in the sludge. Sludge could be used in agriculture as a fertilizer.



o Technical Description of Treatment Processes

In order to minimize transportation cost and to facilitate sludge handling a sludge

dryness of 25% will be targeted.

Anaerobic digestion of the sludge or sludge drying requires high capital expenses

(CAPEX) and a technicality that is not thought to be relevant of the wastewater and

sludge treatment plant.

Overview of possible final disposal routes

Wastewater treatment shall not be envisaged without thinking about the way of

handling the sludge that is produced during the wastewater treatment process. The

following features should be investigated when setting up sludge management plans.

o The quantity and the quality of the sludge, which differ depending on the

processes implemented at the WWTP;

o The local regulatory framework related to sludge management and disposal;

o The possibilities of considering sludge as a product and not only as a waste,

through adapted treatment and/or monitoring procedures.



The main final sludge disposal routes, as can be experienced worldwide, are

presented in the following sections.

Figure 4-2 Presentation of main final sludge disposal routes

Each process for possible final disposal route is detailed in appendix 4-3.

Odour treatment facilities

o Description of the possible odour treatment processes

The main sources of odours in a WWTP are generally located at the following places:

• At the first stages of the wastewater treatment schemes (i.e. in the pre-

treatment building);

• Ιn the sludge treatment building and sludge storage facilities.

Odours are caused by various molecules that are released during the transformation

of wastewater, during its transport in the sewerage network, and the subsequent

wastewater and sludge treatment processes. These molecules can contain sulphide

(such as H2S and mercaptans), nitrogen (ammonia, methylamine, indole, etc.) or

oxygen (various acids) and are spread around the WWTP depending on the wind

direction and strength.

In order to limit odour spreading and to protect the neighbourhood from odours it is

recommended to install the pre-treatment works inside a building from which air is

extracted by dedicated fans and transferred to an air treatment facility. Similarly the



extracted air from the sludge treatment facility would be directed to the air treatment

facility.

Air treatment can be performed in different ways. Chemical and biological and

physical processes can be differentiated as follows.

Physico-chemical treatment

It consists in transferring the molecules at stake from the gas phase to the liquid

phase in a reactor, where air is contacted with chemical solutions of different

characteristics thus allowing the phase transfer. The treated air is released into the

atmosphere while the liquid phase is generally sent back to the wastewater treatment

line.

Biological processes

They rely on the ability of a specific biomass – generally fixed to a supporting material

to degrade the molecules responsible for odours.

Physical processes

They include adsorption onto activated carbon surface, thermal oxidation and photo-

catalysis.

o Process selection

The same criteria apply for the air treatment process selection as for the wastewater

process selection. They are the following:

• Robustness;

• Flexibility;

• Cost-efficiency.

In the local context of Bulgaria it is therefore recommended to extract the air of

sensitive buildings and to transfer the polluted air to biological filters that do require

neither a high CAPEX nor a high OPEX since they are almost maintenance-free and

do not require any chemical.

The polluted air is distributed through the central cylindrical screen of the biofilter to

the filter media and evacuated through the external perforated fibre glass structure.

The filters are filled with special calibrated organic media that provides support for the

biomass to grow and also provides the necessary nutrients that the microorganisms

need in order to biodegrade the volatile pollutants. The lifespan of the filtering media is

5 years. Water is sprayed on top of the filters to provide the necessary humidity for the

microorganisms.

4.1.1.4.5. Climate change impact

Several scenarios have been developed trying to forecast the evolution of climatic

environment and its impact on the regional hydrologic conditions. The effects of a

possible climatic evolution are presented in Appendix 4-4.

Practically, in regions which could be submitted to a reduction of precipitation, the

options to be considered will have to include the improvement of water supply safety



for places already enduring water scarcity or having a water use close to the

maximum potential of natural resource.

PROPOSED UNIT COSTS 4.1.2.

To calculate the investment costs for each investment measures, a Unit Cost Data

Base (UCDB) has been developed. This database is mainly based on the unit cost

database of the Ministry of Environment and Water, which was completed with

missing prices and slightly adjusted.

The calculated investment costs will be compared to cost estimates of available

designs projects, if existing. In case of major differences between cost estimates of

existing design projects and the Consultant’s cost estimate the most reasonable costs

will be retained (expert’s assessment).

The unit costs presented in below are net costs excluding VAT, constant price base

2011 in EURO.

Safety coefficients were applied in case of dense urban context, difficult geological

conditions, asphalt covering.

For settlements with less than 2,000 inhabitants, not connected to an agglomeration

with more than 2,000 inhabitants and with a rate of population connected to the

sewerage system less than 90%, a Sewerage Zoning study must be proposed into

GENERAL METHODOLOGY FOR OPTION ANALYSIS 4.1.3.

Objective 4.1.3.1.

The general objective of the option analysis is, for each identified deficiency in the

systems, to duly justify the proposed investment measures by considering other

alternatives, calculating and comparing costs and benefits and finally selecting the

most appropriate option considering technical, financial and environmental factors.

The process for such analysis is the following:

o Identification and screening of options for each water supply and wastewater

zone, the objective being to define the set of options or alternatives to be

compared;

o Evaluation of options, through NPV calculation and analysis of the key benefits

on health, environment, quality of service.

Identification and screening of options 4.1.3.2.

for each water supply and wastewater zones

Description of key deficiencies

The first step of the option analysis consists in synthesizing, for each of the

agglomerations in the study area, the key deficiencies identified through the

assessment of the existing situation.

Identification of potential options

Then, the potential options enabling to solve these deficiencies and the timeframe for

their implementation, depending on the urgency of rectification, must be clearly

identified. As far as possible, a minimum of 2 options must be considered for each of

the deficiencies to be solved.

Depending on the deficiency to be suppressed, the options can consist in:



o Considering centralized / decentralized systems for water treatment (DWTP and

WWTP);

o Considering various tracings and configurations for the network to be

built/renewed;

Screening based of qualitative analysis – Advantage s / Disadvantages

The third step consists in performing a qualitative analysis of each of the potential

options previously selected and identifying their key advantages / disadvantages from

the technical, sanitary, operational, environmental and social points of view.

Selection of viable options to be further analysed

Then, the options to be evaluated are selected based on the results of the previous

analysis. Ideally, a minimum of 2 options should be considered for each option.

However, for some “trivial” investments, a unique option can be analysed but it should

then clearly be justified.

Evaluation of options 4.1.3.3.

Description of the necessary investments

For each of the options to be evaluated, the investments to be performed need to be

described and quantified in order to further evaluate their cost.

The “basic” design of each of the investments (capacity of pumping stations,

reservoirs, DWTP and WWTP, diameter of the pipes and collectors…) must be briefly

justified (reference to hydraulic / quality calculation).

Risk assessment (externalities - health, environmen tal…)

For each investment, risk assessment will be performed for each selected option in

order to compare them. Risk assessment consists, at the technical, operational,

sanitary, environmental and social levels, in:

o Determining which risks are likely to affect the project;

o Documenting the characteristics of each;

o Assessing the intensity of the impact (High / Medium / Low) and its probability of

occurrence (Unlikely / Probable / Very likely);

o Prioritizing these risks based on the previous parameters.

Cost assessment and financial evaluation

The methodology for cost assessment is the following:

o Assessment of the investment costs based on the Unit Cost Data Base (UCDB,

see 4.1.2) and on case-by-case basis for particular investments, such as

rehabilitation measures;

o Synthesis of the investment costs per category of investment:

• For Water Supply:

� Water Abstraction/Wells;

� Drinking Water Treatment Plant;

� Water Mains;



� Distribution Network;

� Reservoirs and Tanks;

� Pumping Stations;

� Miscellaneous.

• For Sewerage:

� Waste Water Treatment Plant;

� Main Collectors;

� Sewerage Network;

� Pumping Stations;

� Miscellaneous.

o Assessment of the annual operation and maintenance costs for each of the

options and each category of investment (see 4.1.2).

Financial evaluation

Based on these costs, financial evaluation is then performed through NPV (Net

Present Value) calculation with the following parameters:

o Reference period: 2013 – 2038 (25 years);

o Discount rate: 5%;

o Considered lifespan23:

• Pipes: 50 years;

• Civil works : 45 years24;

• Electrical and mechanical equipment: 10 years.

o Renewal of the investment at the end its lifespan (equipment renewed every 10

years…);

o Residual value of the investment at the end of the reference period is assessed

by considering a linear decrease of its value through its lifespan.

Synthesis of selected option

By default, in case the risk levels are not too high and/or similar, the option with the

lowest NPV is selected for each investment.

A table is prepared for each of the investments emphasizing:

o The key deficiency that the investment enable to solve;

o For each evaluated option:

• The risk level;

• The investment and O&M costs;

• The NPV of the investment.

o Justification of the selected option, if it doesn’t have the lowest NPV, due to the

results of risk assessment.

23 As per requirements defined by the National Regulator

24 As per requirements defined by the National Regulator, assuming that Civil works consists of

30% Buildings and 70% Facilities.



GENERAL METHODOLOGY FOR PHASING AND PRIORITIZATION 4.1.4.

Identification of measures 4.1.4.1.

All measures identified by the Consultant during its assessment are included into the

investment program. Projects for which financing has been approved are considered

as “on-going” and therefore have not been included into the investment program. A list

of all on-going measures is presented in appendix 1-1 of chapter 2.

Phasing of investments 4.1.4.2.

The identified investment measures have been grouped into the three investment

phases, based on the following criteria:

Phase 1: Short-term investment program

o All investments necessary to achieve compliance with Directive 91/271/EEC -

Urban Wastewater Treatment Directive (UWWTD) and the respective Bulgarian

legislation. This will include compliance with Article 3 of the UWWTD

(wastewater collection) and Article 4 of the UWWTD (wastewater treatment) as

well as measures necessary to ensure effective operation of the systems;

o All investments necessary to achieve compliance with the Directive 98/83/EC –

Drinking Water Directive (DWD) and the respective Bulgarian legislations. This

will include all measures aiming to remediate major deficiencies related to water

quality and water quantity.

Phase 2: Medium-term investment program

o Investment measures aiming to improve efficiency of the systems (NRW

reduction, energy efficiency);

o Rehabilitation of water supply and wastewater systems to ensure sustainability

(replacement of assets);

o Priority replacement of networks (i.e. asbestos cement pipes, pipes with high

number of bursts);

o Improvement of the level of service (i.e. pressure, shortages…).

Phase 3: Long-term investment program

o All other measures not mentioned above;

o Continuation of measures started in Phase 2 (i.e. measures aiming to reduce

water losses, infiltration into sewer networks, etc).

Prioritization of investment measures 4.1.4.3.

Priorities of investment measures will be defined by the Ministry according to the

European Directives and applied at national level.

A prioritization system based on five criteria has been set up and is presented in

appendix 4-7.



4.2. OPTIONS FOR DEVELOPMENT OF THE WATER SUPPLY

SYSTEM

STRATEGY FOR THE WATER LOSSES MINIMISATION PROGRAM 4.2.1.

The water losses minimisation program is based on four principles, namely:

• Active search of leaks;

• Quick reaction for removal of identified leaks;

• Pressure management and control;

• Target management of assets.

First, it is necessary to define the extent of physical and commercial losses.

However, a program for minimisation of water losses could be successful if it is based

on real situation and specific context. Besides, the approach should include also other

system parameters.

The state of the drinking water systems in Bulgaria and particularly on the territory of

„Vodosnabdiyavane i Kanalizatsiya” OOD - Kardzhali is critical. It can be summarised

as follows:

• Low reliability of water metering at the clients, leading to great uncertainty of

the real extent of physical and commercial losses;

• High level of losses assessed;

• The larger part of the pipes are obsolete, often oversized and in general made

of asbestos cement. This a precondition for substantial risks for public health

(asbestos), as well as for long retention of water - for more than 48 hours,

which creates bacteriological risk (oversized design).

• The number of the illegal connections is based on assumptions made by the

operators and the municipalities, leading to great uncertainty of the real extent

of physical and commercial losses.

In this context, a strategy is proposed, based mainly on target management of assets,

namely:

• Recommendation: The operators should have a policy on management and

replacement of the water meters depending on their age (recommended

maximum between 10 and 14 years), on the efficiency of metering (the size of

the water meter should be designed according to the client’s consumption)

and on the quality of installation and monitoring. The same policy should apply

also for metering points on the external water supply system (the age for

replacement depends on the material). This is an important recommendation,

however it is not integrated because evaluation is not possible, as well as

because of the fact that the program should be financed by the operators.

• Application of priority measure: Replacement /renovation/ rehabilitation of

pipes. This is the only measure that could significantly reduce both physical

losses and health risks (simultaneous removal of asbestos cement pipes and



new size design). Besides, the implementation of a policy on systematic

replacement of service connections facilitates the localisation of illegal

connections, therefore reduces commercial losses.

• The second step proposed for the big water systems consists in

implementation of the principle for pressure control. In fact, the extent of

physical losses can be significantly reduced through installation of

independent pressure regulators in appropriate (possible) points (without

using external force). The role of these regulators is to reduce pressure in low

consumption periods (usually during the night) and to allow bigger pressure

during peak periods. The extent of losses theoretically depends on the

diameter and the shape of the pipe, of the material it is made of as well as on

the water pressure.

• Finally, in medium term and in long term, the consultant proposes applying the

principle for diagnostics and on-going monitoring of the flow, the pressure and

the water level at the production point, but to work on strategic points of the

distribution network. This ensures the establishment of a permanent system

for sectorisation. Based on the results of the internal monitoring, it is possible

to conduct survey programs and removal of leaks. This principle is applicable

only when the real extent of the losses is within the acceptable limits (below

30-35%) in order to achieve efficiency of approximately 80-90%.

STRATEGIC ALTERNATIVES FOR THE DISTRIBUTION NETWORKS 4.2.4.

The distribution networks of the settlements within the designated territory serve 100%

of the population; however, it does not mean that these are 100% completed. In many

places, clients are supplied but there is no street water main. The clients are supplied

from a nearby service connection or deviation that crosses private properties. In this

case, it is necessary, with the future development of the water supply network, to

construct street water mains where these are missing; this means that construction of

new water supply networks is envisaged. Having in mind the average rate of non-

revenue water at the WSS Company reaching 50%, investments shall be needed in

order to achieve the target of 32% NRW in 2012 and 25% in 2038

SYSTEM

STRATEGIC ALTERNATIVES FOR WASTEWATER SYSTEMS 4.3.1.

As mentioned in Chapter 3, all surface water receiving bodies on the territory of

„Vodosnabdyavane i Kanalizatsiya” OOD – Kardzhali are included in the list of

„sensitive zones” (Arda River and its tributaries). The consultant reminds that

according to 91/271/ЕЕС Directive, WWTP with capacity above 10 000 P.E.,

discharging wastewater in „sensitive zones”, should be equipped with tertiary

treatment unit for nitrogen and phosphorus removal. In order to comply with European

norms, all WWTPs on the territory of „ViK“ OOD – Kardzhali should respect the

following maximum concentrations in treated water:



Table 4-15 Maximum concentration in treated water

Defining alternatives 4.3.1.1.

Scope of the alternatives

The scope of discussed alternatives includes:

• agglomerations of more than 2000 inhabitants;

• agglomerations of less than 2 000 inhabitants, which can be included in

existing or future WWTP.

Agglomerations, concerned by the alternatives

The table here below shows the agglomerations, for which treatment of wastewater

(without wastewater from public and industrial activities) is envisaged as well as their

Settlements, not concerned by the alternatives

For the settlements, not concerned by any of the categories, for which the population

connectivity rate (wastewater network) is below 90%, it is proposed to carry out

studies of the wastewater zones in the short-term investment program. As mentioned

in section 4.1.2.2 „The Study of the wastewater zones shall identify the best options

among joint wastewater network, small collection wastewater network, independent

wastewater network and systems for treatment of stormwater for the studied

settlements“. Then the solutions, presented in the Study of the wastewater zones,

shall be proposed for approval in medium-term and long-term investment programs.

For „ViK” OOD - Kardzhali shall be carried out Studies of wastewater zones in the rest

of the settlements (the settlements of the service territory, except for the 6, concerned

by the alternatives, listed in table 4-18). The table here below summarises the scope

of the Studies of wastewater zones:

Sludge management 4.3.1.2.

This chapter includes all urban wastewater treatment plants, constructed or previewed

for construction in the short-term, medium-term or long-term programs.

The methods for treatment of sludge and the options for their final reuse are

described in details in the chapter dedicated to the methodology (section 4.1.1.4.4

Technical criteria for design, subsection Treatment of wastewater sludge).

In Bulgaria, the final destination of the sludge in almost all cases is the transportation

and disposal on waste landfills. However, in some cases the sludge is being improved

after its decomposition (usually vermiculture) in order to use it for the soil (not in

agriculture).

This situation comes from the fact that, first, non-domestic discharges are not

controlled by the operators (risk of pollution of sludge) and, second, to the fact that

there are no studies conducted on the perspectives of management of sludge for use

in the agriculture.

These studies and actions are covered by the feasibility studies and the design (or

special studies) and are not included as a part of the present Master plan. Therefore,

the investment programs of the Consultant does not include such measures.

However, the Consultant recommends the future feasibility studies and design to

follow this idea but also to initiate specific study for actions on the national level and

identify several pilot projects.

The consultant recommends possible alternatives for management of sludge for future

feasibility and design studies, as well as for initiating a special study for actions on

the national level with several pilot projects.

The above mentioned study includes several components:

• Analyses and proposed changes in the regulations concerning the

management of sludge in Bulgaria;

• Assessment of the state of the industry in the pilot projects;

• Assessment of the existing management of sludge in the pilot projects;

• Defining the possible use in the agriculture of the pilot projects;

• Future interaction with potential users;

• Socio-economic measures and communication for creating awareness of

the concerned public;



• Education on projects.

Cooperation in the implementation of the contracts between the operators and the

end users of wastewater sludge. The consultant recommends integrating the reuse of

treated water from WWTP with this approach for management of sludge.

The consultant recommends selecting one or several pilot projects on the territory of

„Vodosnabdiyavane i Kanalizatsiya” OOD - Kardzhali.

Assessment of the alternatives for 4.3.1.3.

Agglomeration Kardzhali

For agglomeration Kardzhali there is an on-going project for construction of a WWTP

Agglomeration Krumovgrad

For WWTP Krumovgrad there are prepared: preliminary design and feasibility studies.

There is an option retained for centralised WWTP and possibility to connect the village

of Vransko and the village of Polkovnik Zhelyazovo. These two settlements have

approximately 50% constructed wastewater network and constructed leading

collectors, respectively from the village of Vransko - to the wastewater network of the

town of Krumovgrad and from the village of Polkovnik Zhelyazovo - to leading collector

of the town of Krumovgrad. Therefore, decentralised alternative is not discussed.

There is no possibility to connect other settlements, having in mind their location,

Agglomeration Ardino

The Feasibility study conducted in 2012 does not propose and discuss another

alternative for Agglomeration Ardino besides the centralised one – construction of

WWTP on the regulated territory of the town of Ardino. Decentralised alternative is not

acceptable due to several factors: settlements located nearby (village of Bistrogled –

37 inhabitants; village of Pravdolyub – 178 inhabitants) have small population (with a

trend to decrease); no wastewater network is constructed; complex terrain

configuration – leading collectors more than 2 km long in heavily broken area.

Agglomeration Benkovski

The village of Benkovski has a wastewater network constructed that covers 45 % of

the population. There is a project prepared: Feasibility study in 2012. According to

this study and the analyses of the Consultant, it can be concluded that there is no

possibility to connect other settlements. The settlements near the village of Benkovski

have very small population, there are located too far for gravity collection of

wastewater, no wastewater network is constructed. This is the reason why no

alternative is proposed for connecting the settlements to Benkovski.

ALTERNATIVES FOR WASTEWATER NETWORKS 4.3.2.

Management of non-domestic 4.3.2.1.

wastewater

The present chapter concerns all the types of non-domestic wastewater in the

wastewater network of the settlements. However, it does not take in account the

industrial companies, discharging their wastewater directly in the receiving body, as

the authority responsible for this is RIEW. The recommendations listed here below

concern only the industrial companies, discharging into the wastewater collection

system.

The implementation of the present Master plan shows that, in general, the WWS

companies do not cope with the management of such wastewater.



The specificity and the quantity of these wastewater have significant impact on the

management of the wastewater collection systems and WWTP. They have impact

also on the treated water and sludge, as their quality directly affects the possible

options for reuse (p.ex. in the agriculture) and their final destination.

The framework of the Master plan does not include the study of each separate case.

However, it is possible to make a general recommendation. It is important to point out

that the Bulgaria legislation is not entirely harmonised with the respective European

directives. Therefore, it is hard to identify specific measures, without contradicting the

different regulations.

The consultant recommends conducting a comprehensive study that could include the

following:

• General study on the national nation:

o Analyses and review of the European legislation

o Analyses and assessment of the Bulgarian legislation

o Proposal for amendments

• General principles applied on local level

Establishment of a specific contract between the WSS Company and all the

concerned parties in the wastewater network sector that could include the following:

o Description of the industrial processes and the character of the

generated wastewater.

o Establishment of a point for on-going monitoring of the flow and

periodical transmission of data to the WSS company and the

respective public authorities (municipality, municipal council and

others).

o Control through a point for monitoring of pollution and transmission of

periodic data to the WSS company and the respective public

authorities (selection of parameters, depending on the specificity of

the wastewater, minimum values of COD, BOD5,, Total suspended

solids, N, P).

o Permit for discharge with a description of permissible parameters of

the wastewater

Wastewater treatment before discharge into the wastewater collection system with

strict monitoring and periodic transmission of data to the WSS Company and the

respective public authorities, if necessary.

Defining the alternatives for 4.3.2.2.

wastewater network of agglomeration Kardzhali

The alternatives that should be reviewed for a wastewater system could be :

- With regard to the choice of system: combined, separate or mixture of

combined and separate system (when the settlement has areas with

combined system and areas with separate system)



- With regard to the scheme of the solution for the wastewater network

The town of Kardzhali has 87 km of constructed wastewater network and 97%

population connectivity rate. The wastewater system is constructed and operating as

combined, i.e. domestic wastewater, stormwater and industrial wastewater are

collected in the same pipe. In the town of Kardzhali, there is no WWTP. There is no

alternative of the solution regarding the wastewater network. Alternative could be

found concerning the development of the wastewater infrastructure over the time

according to the general targets mentioned for improvement and development.

Under procedure №BG161РО005/10/1.10/02/16 „Improvement and development of

the infrastructure for drinking water and wastewater in agglomerations over 10 000

P.E.” the Municipality of Kardzhali is granted with financial aid № DIR- 51011116-

С001 for „Integrated water project of the town of Kardzhali: Construction of WWTP

and leading collector, extension and reconstruction of the water supply and

wastewater network“. The project includes construction and reconstruction of 23.24

km wastewater network in quarter ”Prileptsi”, quarter ”Vazrozhdentsi”, quarter

”Terasite”, Main collector II to leading collector to WWTP, Main collector X to the point

is joins Main collector I, Main collector XI, Main collector X` to the point it joins Main

collector X. The quarters of Gledka and Gorna Gledka are not connected due to the

limited financial resources.

The implementation of the above-stated project will solve the urgent problems

concerning the wastewater system, but the sewerage network in the quarters of

Gledka and Gorna Gledka is left to be completed.

The Consultant envisages the following measures for solution of problems identified

for the wastewater network :

- Completion of wastewater network;

- Reconstruction of sections of the network in order to achieve the necessary

conductivity;

- Reconstruction of the network where the sewers are installed less deep that

required by the regulations;

- Reconstruction of sections, constructed with gradients smaller than the

permissible, which creates condition for silting up and blockages;

- Reconstruction of the network where the water-tightness of the pipes and the

fixtures is compromised, which is a precondition for high levels of infiltration.

The consultant recommends only for quarter ”Gorna gledka” the construction

of a separate system. For all the other quarters, the wastewater system

remains combined.

The investment programs for agglomeration Kardzhali envisages:

- Short-term investment program: new wastewater network – 2.53 km and

reconstruction – 0.61 km;

- Medium-term investment program: new wastewater network – 19.07 km and




- Long-term investment program: new stormwater network – 2.69 km and

reconstruction – 40.57 km


wastewater network of agglomeration Momchilgrad

The town of Momchilgrad has 18,74 km constructed wastewater network, the

wastewater collection system is combined and it collects domestic, industrial and

stormwater. Population connectivity rate for the wastewater network is 95%. There is

no WWTP.

For the Municipality of Momchilgrad there is a project prepared “Reconstruction,

modernisation and completion of the WSS network and construction of UWWTP in the

town of Momchilgrad. Under Procedure with reference №

BG161PO005/10/1.11/02/16 „Improvement and development of the infrastructure for

drinking water and wastewater in agglomerations over 10 000 P.E.“ under Operational

Programme Environment 2007-2013, Priority Axe 1, there is financing provided for the

project. The project envisages the construction of 6,32 km new network,

reconstruction of existing wastewater network – 8,47 km. The system should be

transformed from combined into mixture of combined and separate system.

The Consultant does not envisage short-term investment program. The urgent

problems associated with the wastewater system are solved in the financed project.

The strategic investments for the wastewater network for the medium-term and long-

term investment program consist in :

- Reconstruction of the main collectors in order to achieve the necessary

conductivity;

- Reconstruction of the network where pipes are installed less deep than

required, where the conductivity is insufficient and the water-tightness of the

pipes and the fixtures is compromised, which is a precondition for high levels of

infiltration.

The investment programs for the town of Momchilgrad envisage:

- Medium-term investment program: reconstructed wastewater network – 4.99

km;

- Long-term investment program: reconstructed wastewater network – 3.64 km.


wastewater network of agglomeration Krumovgrad

The town of Krumovgrad does not have a WWTP. The town has 17,71 km

wastewater network constructed and population connectivity rate of 96%. The system

is combined, the choice is made with the commencement of the construction of the

wastewater network. The scheme has been selected then too. Therefore, for the town

of Krumovgrad there is no alternative for the solution concerning the wastewater

network. Alternative solution could be found with regard to the development of the

wastewater infrastructure over the time according to the general targets listed for

improvement and development of the wastewater infrastructure.



The envisaged measures are in connection with the problems identified in the

wastewater network.

- Reduced conductivity due to alluvium;

- insufficient conductivity due to small diameters;

- High levels of infiltration due to compromised water-tightness of the pipes and

the fixtures, which creates a risk of pollution of the environment and affects

the operation of the WWTP;

- Reconstruction of the main collectors and the internal network in order to

achieve the necessary conductivity of the network and eliminate the

wastewater discharges in open water courses.

For Agglomeration Krumovgrad, as described in item 4.3.1.5, centralised alternative

for the wastewater system is proposed. The two settlements connected to the centre

Krumovgrad have constructed domestic wastewater network – approximately 50%

(based on data obtained from the Municipality of Krumovgrad) and entirely

constructed leading collectors. The consultant envisages the extension of wastewater

networks together for the two settlements: 4.38 km new wastewater network in the

short-term program (in order to achieve 90% population connectivity rate) and 1.36 km

in long-term program (in order to achieve 100% population connectivity rate).

The investment programs for agglomeration Krumovgrad envisage:

- Short-term investment program: construction of new wastewater network

11.18 km and reconstruction – 2.21 km;

- Medium-term investment program: reconstructed wastewater network – 5.71

km;

- Long-term investment program: new wastewater network – 3.46 km and



wastewater network of agglomeration Ardino

The existing wastewater system in the town of Ardino is combined – for domestic

wastewater and stormwater. It is made of concrete pipes ø150 and ø200 mm. The

technical state of the wastewater network is bad and it is characterised by insufficient

conductivity (small diameters of the pipes), reduced mechanic strength of the concrete

pipes and high permeability of the walls due to the specific chemical composition of

the water (soft water), intensive silting up . All these cause frequent failures, flooding

with polluted water of houses, streets, terrains, high levels of infiltration. It is necessary

to construct a new wastewater system that would, besides solving the problems of the

existing network, also cover the entire population of the town.

There is an alternative for new wastewater system in the town of Ardino. There is an

option for separate wastewater system proposed also in the project elaborated in 2011

Feasibility studies. The consultant also considers this to the be the best alternative.

The existing wastewater network - main collectors and secondary branches for

combined wastewater shall function as stormwater system. For the domestic



wastewater, new wastewater network shall be constructed – main one and secondary

one. Eliminating the negative impact of the stormwater shall ensure the normal

operation of the WWTP previewed for construction. Currently the stormwater

introduces a lot of sand and other impurities into the combined wastewater system

due to several reasons:

� Street infrastructure not good enough;

� Very high gradient of the streets towards Ardinska River and in case of rains

the stormwater drags and introduces through the overflows any mechanic

impurities into the wastewater pipes with small diameter – it results in

blockage and flooding with polluted water of the ground floors of buildings, as

well as streets and terrains in the lower part of the town;

� Because of the terrain specificity of the town (high gradient of the terrain

towards the river), there are support walls constructed under the properties

along the street and in case of rain part of the soil from the yards, together

with grass, leaves, branches, is dragged to the street – an additional

precondition for blockage and silting up of the pipes with mixed outflow.

Based on the mentioned above, the alternative consists in separate wastewater

system for the town of Ardino.

The following measures are envisaged for the solution of the identified problems:

reconstruction of the existing wastewater network and construction of new one in

order to achieve 100% population connectivity rate, as well as full treatment of

wastewater entirely collected and sent to WWTP.

The investment programs for the town of Ardino envisage:

- Short-term investment program: construction of new wastewater network 4.35

km and reconstruction – 4.36 km;

- Medium-term investment program: new wastewater network - 4.06 km;

- Long-term investment program: new wastewater network - 1.36 km and



wastewater network of agglomeration Dzhebel

The town of Dzhebel has 16,77 km constructed wastewater network, the wastewater

collection system is combined and it collects together domestic wastewater, industrial

wastewater and stormwater. Population connectivity rate for the wastewater network is

87%. There is no WWTP.

The relief of the town of Dzhebel is cut by Dzhebelska River and several creeks. This

is have predefined the solution for the wastewater network – perpendicularly cut

wastewater scheme with a main collector in the lowest part along the river. The

existing wastewater network serves the central part of the town and part of the

quarters „Izgrev”, „Bryagovo”, „Mladost 1”, „Mladost 3” and „Progres”. As there is no

WWTP, the collected wastewater is discharged mainly into Dzhebelska River, for

which there is a permit for discharge issued, but there is also unauthorised discharge



in creeks. The presence of numerous creeks crossing the town provides the possibility

to search an alternative for the combined wastewater system, especially with regard to

the newly constructed wastewater network, with a solution for separate system. The

Feasibility study conducted in 2012 is based on this idea too. The consultant proposes

the existing combined wastewater system in the central part of the town, part of

quarter ”Izgrev” and part of the Industrial zone to be reconstructed in a way to find an

optimum possibility, technically feasible and financially advantageous, to transform it

into a separate system (it solves better environmental problems). Where it is proven

possible, the existing combined wastewater sewers shall be kept for the collection of

stormwater only, and a new one shall be constructed for domestic and industrial

wastewater quantities. The completion of the wastewater network up to 100% in this

part of the town is envisaged – with the design of mainly domestic wastewater

branches; the stormwater shall run free down the streets to existing overflows or

nearby creek. Having in mind the good infrastructure of the quarters, the density and

the type of construction and structural features, the combined wastewater system is

kept for the central part of the town after the reconstruction.

For the satellite quarters with family houses - „Bryagovo”, „Mladost 1”, „Mladost 2”,

Mladost 3”, „Gotvarsko” and part of quarter ”Progres” the project solution consists in

entirely separate wastewater system where stormwater network shall be simplified

and reduced with regard to the configuration of the relief, the existing creeks, the

degree of completion of the infrastructure.

The short-term program envisages investments for :

� reconstruction of the existing urban wastewater network – leading collector,

main collector and problematic sections of the secondary network in the

central part of the town;

� extension of the wastewater network in quarters with partially constructed

wastewater network;

� construction of new wastewater infrastructure in quarters of the town of

Dzhebel and in the other settlements of the agglomeration.

For Agglomeration Dzhebel, as explained in item 4.3.1.7, we have proposed

centralised alternative for the wastewater system. For the four connected settlements,

no wastewater network is constructed. The consultant envisages the construction of

separate wastewater systems total for the four settlements: 5.85 km new wastewater

network and leading collectors to WWTP – 2.99 km in the short-term program (in order

to achieve population connectivity rate of 90%) and 0.65 km in the long-term program

(in order to achieve 100% population connectivity rate).

The investment programs for agglomeration Dzhebel envisage:

- Short-term investment program: construction of new wastewater network

17.14 km and reconstruction – 7.37 km;

- Medium-term investment program: new wastewater network - 5.09 km and




- Long-term investment program: new wastewater network - 1.36 km and

reconstruction – 2.01 km.


wastewater network of agglomeration Benkovski

The village of Benkovski has 5.067 km constructed wastewater network, of which 2.42

km are constructed after 2005 and this section is in good hydro technical state. The

leading collector to the site selected for the WWTP is also constructed. The

wastewater infrastructure serves only the population of the south part of the village.

This part includes all the administration, public and cultural buildings, the density of

construction is much higher and the infrastructure of the village is relatively good. The

wastewater system of the existing wastewater network is combined – domestic

wastewater and stormwater are collected together wastewater, there is no industrial

wastewater.

There is a project prepared in 2012 for the village of Benkovski – Feasibility study for

the water supply and wastewater infrastructures. This project proposes extending the

wastewater network in the south zone (up to 100% population connectivity rate) as

combined system.

For the north zone, which has small construction density, less developed infrastructure

– with many unfinished and uncoated streets, with many green areas, the consultant

envisages the construction of a separate wastewater system, mainly domestic

wastewater network.

Concerning the south zone, the consultant proposes for the extension of the

wastewater network to search for an alternative for the combined wastewater system

by identifying zones (or sections) for separate system. The configuration of the relief is

favourable for this solution with the existing creeks and the constructed in the past

several big drain sewers. The separate wastewater system is a better solution with

regard to the protection of environment and water, as well as with regard to the

technical and economic assessment of the wastewater treatment process.

The investment programs for the village of Benkovski envisage:

- Short-term investment program: construction of new wastewater network 8.48

km and reconstruction – 0.30 km;

- Medium-term investment program: new wastewater network – 1.47 km and

reconstruction – 0.58 km.

- Long-term investment program: new wastewater network- 1.36 km and




5. SOCIO-ECONOMIC PROJECTIONS AND MACROAFFORDABILITY ASSESSMENT

5.1. SOCIO-ECONOMIC PROJECTIONS

MACROECONOMIC FORECAST 5.1.1.

Macro-economic forecasts include relevant projections for gross-domestic product,

inflation and unemployment rates at national and regional levels to be used in the

financial analysis of selected investment measures. These forecasts are important as

they exert significant influence over future operation and maintenance costs of water

and wastewater systems, household incomes and affordability constraints. Relevant

details for the specific impact and application of each indicator within the framework of

water and sewerage investments are provided in its respective section.

Macro-economic projections are based on existing statistical data from official

sources (National Statistical Institute, Regional Statistical Bureaus, National

settlement register, Eurostat, International Monetary Fund, World Bank, etc.) and

international and national guidance and methodological materials (Guidelines for cost

benefit analysis of water and wastewater projects supported by the Cohesion fund in

2007-2013). These documents are cited accordingly throughout the report.

Gross-domestic product

Gross-domestic product (GDP) forecasts are indicative for the level of economic

development at a certain territorial level (national, regional, local). In addition, real

growth of GDP is the main indicator used for income projections25 and expenditures

for salaries and wages within the financial analysis of investment measures.

Consequently, as a major driver for household income, GDP growth projections are

crucial for determining macro affordability thresholds and therefore for establishing the

maximum value of proposed investments in water and wastewater systems and

networks.

As indicated in Section 2.3, GDP growth in the country has slowed down considerably

since 2009, which was the first time in 10 years with a negative economic growth,

caused by the consequences from the global financial and economic crisis. Current

annual growth is within the limits of 0.5% to 2.0% and much lower than pre-crisis

levels of 6%.

The “Guidelines for cost benefit analysis of water and wastewater projects supported

by the Cohesion fund in 2007-2013”, prepared with the assistance of JASPERS,

25 “It is recommended to consider household’s disposable income growth as equal to GDP

growth. As a result, current data collected, split by income decile, will be projected using a

growth rate equal to the GDP growth” - Guidelines for cost benefit analysis of water and

wastewater projects supported by the Cohesion fund in 2007-2013



assumes the following dynamics of real GDP growth over the period 2006-2021and

beyond.

Table 5-1 GDP growth assumptions (% per annum), Guideline for CBA

2006 2007 2008 2009 2010 2011 2012 2013 2014 2015 2016 2017 2018 2019 2020

6.32 6.17 6.5 6.5 6.9 6.4 5.7 5.34 5.02 4.67 4.39 4.02 3.74 3.57 3.38

2021 and beyond 3.3

The Guidelines advise that the assumptions should be used cautiously, making sure

that they are consistent with the latest published forecasts. Since the above

projections are based on figures before the crisis period, they need to be adjusted in

accordance with current trends and economic development scenarios.

Several prominent financial institutions produce short- and medium-term economic

forecasts. The International Monetary Fund (IMF) predicts Bulgarian real GDP growth

of 0.8% for 2012, 1.5% for 2013 and 4.5% for 2014 (Source:

http://www.imf.org/external/pubs/ft/weo/2012/01/pdf/text.pdf, World Economic Outlook

2012). An average growth of 2.7% for the period 2012-16 is expected by the

Economist Intelligence Unit (EIU) with 0.7% increase for 2012 (Source: EIU Country

Report – Bulgaria, http://country.eiu.com). The World Bank foresees a very modest

growth of 0.6% for 2012 and 2.5% and 3.3% for 2013 and 2014 respectively (Source:

EU11 Regular Economic Report, June 2012).

On the basis of the projections of these international financial organisations, the

following GDP growth pattern has been established.:

Table 5-2 GDP growth assumptions (% per annum)

2012 2013 2014 2015 2016 2017 2018 2019 2020 and beyond

1.2 1.9 3.5 4.0 3.3 3.3 3.3 3.3 3.3

Valid long-term GDP forecasts are very difficult to provide keeping in mind the

uncertainty in European economic development. For these reasons, the long-term

assumptions of the CBA Guidelines for annual increase of 3.3% have been used for

years 2017 and beyond. This is considered realistic and in line with expected EU

economic growth.

As indicated in section 2.3, regional GDP per capita is lower than the national

average, being approximately 75% of it (see chapter 2 - figure 2-2) and the gap

between them is widening. However, the major reason for this difference is the

different starting point and not the actual increase rate, which is approximately 13% for

the country and 12% for the region when nominal GDP values are used. Since the

increase rates are similar both at national and regional level, the growth assumptions,

depicted in Table 5-2 can also be applied for GDP projections in the service area

without significant loss of forecast reliability

Inflation

Inflation level forecasts are important for water and wastewater investments for two

major reasons:



1) inflation is used to determine constant and nominal costs and tariffs (e.g.

conversion of data from operators’ business plans);

2) some relevant cost components (e.g. fuels, electricity, etc.) might increase or

decrease with lower or higher rates than the average inflation rate, which

influences cost projections when constant values are used.

These considerations require that inflation forecasts are provided on 2 separate levels

– total inflation, represented by the consumer price index and inflation for major cost

components, used in water and wastewater investment projects. The differences

between these two levels can be used when projecting the various costs for the

proposed investment measures.

Average national inflation rate for the last 10 years has been 5.7%, ranging widely

from 2.3% (2003) to 12.3% (2008). The last three years from this period (2009-2011)

are most relevant as inflation has stabilised within narrower boundaries and an

average value of 3.1%.

The “Guidelines for cost benefit analysis of water and wastewater projects supported

by the Cohesion fund in 2007-2013” assume the following dynamics of inflation rate

over the 2006-2021:

Table 5-3 Inflation dynamics assumptions (growth rate per annum in %)

2006 2007 2008 2009 2010 2011 2012 2013 and beyond

6.08 11.57 9.24 4.41 5.22 4.07 3.00 2.7

IMF forecasts inflation rate of 2.1% in 2012, 2.3% in 2013 and 2.7% in 2014 (Source:

World Economic Outlook Database, April 2012). Average inflation, according to the

EIU, will be 2.7%, 2.5% and 3.5% for 2012, 2013 and 2014 respectively.

As the proposed values of inflation within the CBA Guidelines are consistent with the

ones proposed by the most recent projections of international financial institutions,

they are considered relevant and can be used in the financial analysis of investment

alternatives.

Projection of operation and maintenance costs of water and wastewater systems

requires prediction of individual inflation rates for the major cost categories –

materials, fuels and electricity, and external services. These categories are not

identically represented in the consumer price index and the following categories have

been used as closest substitutions: non-food products, electricity, liquid fuels and

services. The dynamics of these categories over the last 3-year period is presented in

Table 5-4.

Table 5-4 Inflation dynamics of major cost categories (growth rate per annum in %)

2009 2010 2011 Average Ratio to total inflation

Total inflation 2.8 2.4 4.2 3.1

Non-foods (materials) 3.6 6.5 3.5 4.5 1.46

Services (incl. external) 4.8 1.2 1.6 2.5 0.82

Electricity 5.0 -0.8 1.9 2.1 0.67

Liquid fuels -21.1 19.7 13.5 4.0 1.30



Materials and fuel prices grow at a faster rate compared to average inflation, while

electricity and services tend to rise slower than the average inflation. Electricity and

fuel prices in Bulgaria are dependent on global commodity prices thus making

projections somewhat unreliable, but the existing stable trends provide some

assurance to calculations. This reasoning is applied when determining growth

assumptions for these major cost categories over the years.

Table 5-5 Inflation dynamics assumptions – cost categories (growth rate per annum in %)

2012 2013 and beyond

Total inflation 3.00 2.70

Non-foods (materials) 2.10 1.80

Services (incl. external) 3.70 3.30

Electricity 4.50 4.00

Liquid fuels 2.30 2.10

Exchange rate

Exchange rate is kept at a constant level of 1.95583 BGN for 1 EUR. No recent

changes are expected in this aspect. Even if Bulgaria joins the euro zone, the fixed

rate will be applied for the conversion. The unlikely event of floating exchange rate will

have immediate effect on inflation, which cannot be quantified at the present moment.

Taxation

All direct and indirect taxes (Table 5-6) are assumed to remain constant throughout

the reference period of the master plan. Every change of these (and especially indirect

taxes) will have immediate and potentially undesirable effect on inflation. If any long-

term changes take place, inflation forecasts will need to be revised at least for the year

of the change.

Table 5-6 Taxes by categories, 2011

Taxes Value

Corporate tax 10%

Income tax 10%

Value Added Tax (VAT) 20%

Social security 22.3%

Health insurance 8%

Social security tax has different values depending on the scope of services for the

insured persons - pensions, sickness, illness, maternity, etc., and also the year of birth

(those born after 1959 have to pay an additional 5% for additional compulsory pension

insurance). An average rate is adopted for the country, with employers currently

paying about 60% of the contributions due, with a tendency to change this ratio by

2015 to 50% / 50% for the employer and employee respectively.

Unemployment

Unemployment levels have a noteworthy influence in water and wastewater

investment projects and particularly on income projections and macro-affordability

thresholds. Areas with higher unemployment have lower income and different income

structure, relying more on pensions, social benefits and subsistence farming. These



characteristics lead to lower affordability thresholds thus hindering large-scale

investments.

As indicated in Section 2.3., the unemployment in the service area is app. 3% higher

than the national average. The prognosis is that the unemployment will follow the

national trends but the regional specifics will remain unchanged during the reference

period which means that the income structure will remain similar to the present one.

FORECAST OF POPULATION GROWTH 5.1.2.

Introduction

In 2011 the population of the serviced area “Water supply and sewerage” OOD –

Kardzhali is 135,274 people – there is a decrease of app. 5% compared to 2001.

Two scenarios have been developed for the future population of the territory – realistic

and pessimistic. An optimistic scenario , envisaging faster growth, is not applicable

given the current age structure, economic development and out-migration levels. All

scenarios use strictly official Census data (2001, 2011). No adjustments have been

made for possible undercounts as the reports of NSI indicate low levels of

unaccounted people.

The realistic scenario (low negative growth) assumes that population development

will follow recent historical trends with respect both to natural and mechanical

changes. However, the scenario assumes that the loss of population will be slower

because of the currently stable age structure, which is already identical to the national

averages. Out-migration is also likely to be reduced, although some further internal

rural-urban migration can be expected. Nevertheless, internal migration is a

phenomenon that is volatile and at regional level may change dramatically in a very

short time. The scenario assumes slow but constant regional economic growth,

generating opportunities for new jobs, attracting skilled and well-educated young

people, gaining support from favourable regional policies as key conditions for the

successful development of regional economy.

The pessimistic scenario (high negative growth) assumes a demographic

development identical to historical trends and further worsening of negative population

tendencies. This hypothetical scenario does not account for the positive influence of

improving economic situation and regional attractiveness. Out-migration is kept at the

same level, additionally contributing towards the depopulation process. The scenario

assumes that regional inequality will remain constant at the jump-off level until the end

of the projection period (no convergence between regions), corresponding to relatively

poor socio-economic developments.

The key reasons for the possible decline of population in all scenarios include the

relatively large number of people in older age groups (65+), the smaller proportion of

female population reaching fertility age during the reference period of the master plan,

covered by these projections and the significant out-migration. Although increased

birth rates are expected, based on statistical data, they cannot immediately offset the

demographic crisis that has hit the area since 1990, resulting in reduced number of

births.



Methodology

Ideally, population projections at regional level need to be prepared by using a cohort-

component procedure. Unlike simple extrapolation techniques, such as discounting

methods and regression, which project future population without disaggregating it, or

identifying the causes for past trends, cohort-component procedures deal separately

with the three major components of population change – fertility, mortality and

migration. The method is based on the traditional demographic accounting principle:

Population

(at the end of the

period)

=

Population

(at the beginning of

the period)

+

Births

-

Deaths

+ / -

Migration

Unfortunately, there is no possibility to establish age-gender cohorts at individual

settlement level, because such information is not reported by the national statistics.

However, the cohort-component procedure is used by NSI and Eurostat in the

preparation of aggregated forecasts at NUTS III level (districts).

The projection model used by these institutions is characterised by the following

features:

� Fertility: age-specific fertility rates applied to the female population;

breakdown of births into boys and girls in fixed proportions (51.5% boys,

48.5% girls);

� Mortality: age- and sex-specific death rates applied to population;;

� Migration: net migration by age and sex (international and internal migration).

For each of the regional population projections scenarios, assumptions have been

formulated in terms of key summary measures for each component of population

change. The key summary measures are the following:

� Fertility: cohort total fertility rate, total fertility rate, mean age at childbearing;

� Mortality: life expectancy at birth, for men and women separately

� Migration: measuring the intensity of moving to another region.

These key summary measures are subsequently translated into numerical values for

each year of the projection period. The regional population projections are

conceptually a straightforward generalisation of the national population projections:

the only difference is that, while in the national projections the population is just

classified by age and sex, in the regional projections there is an additional dimension

of population breakdown, namely region of residence.

To ensure full consistency between the national and regional scenario, the regional

projection model checks, for each type of event, whether the regional numbers add up

to the national number from the national scenario. If not, the regional numbers of

events are proportionally adjusted to the national level.

The results of this procedure are summarised in regional projections tables for each

district in three scenarios (pessimistic, realistic and optimistic). Table 5-7 indicates the

relevant values for the three districts included in the service area in the pessimistic



and realistic scenarios and Table 5-8 calculates the annual population change, which

reflects all major demographic components – births, deaths and migration

In order to account for local level differences, sensitivity coefficients have been

obtained at settlement level by deriving a ratio between the 2001-2011 change in

population at settlement and district level. These coefficients indicate how individual

settlements change demographically with respect to the region and are later used to

adjust the above regional projections for each settlement.

Sensitivity coefficient at settlement level =

Yearly change in population (settlement)

2001-2011

Yearly change in population (district)

2001-2011

If any obvious inconsistencies (e.g. growth rate much higher or lower than expected)

exist between NSI / Eurostat projections and 2011 Census data, these are adjusted to

reflect the most recent data. All adjustments are clearly indicated in the report.

Summary results

On the basis of the proposed methodology, the following results have been obtained

for population change in the service territory of WSS Kardzhali in the two scenarios.

The realistic scenario envisages a decline of 18 705 people, representing annual

decrease of 0,48%. The annual decline in the pessimistic scenario is 0,51 % per

annum. Regardless that the average rates are relatively low they can be considered

realistic given the historic depopulation at a rate of app. 0,5 % per year between the

two censuses.

The realistic scenario should be used as a foundation for all further calculations about

future investments in the water and wastewater networks as it is based on

assumptions, which are most likely to happen in the service area during the reference

period of the master plan. The pessimistic scenario is necessary only for potential risk

assessment of proposed investments in order to prove their viability in unfavourable

conditions

Detailed results

The detailed results on settlement level are presented in Table 5-9. These are

provided for the realistic scenario only, as the numbers are used for determination of

future water demand and affordability calculations. At the end of the reference period,

6 settlements within the service area will have population over 2000 people.

The proposed population projections should not be considered as precise forecasts.

They show the probable demographic development on the basis of educated and

realistic assumptions about fertility, mortality, migration, economic development and

unified methodology for regional predictions, applicable across the EU.

FORECAST OF BUSINESS DEVELOPMENT 5.1.3.

The major non-domestic water consumers, indicated in Section 2.3 are the enterprises

of the mining industry, manufacturing industry and the food-processing industry .

This situation is expected to remain relatively constant during the reference period of

the master plan as production will grow slowly with the increase in national and

international consumption. . New small and medium enterprises are expected to

emerge, which will not influence water demand significantly. Currently the small and

medium enterprises account for over 97% of the companies on the serviced area of

WSS OOD - Kardzhali. There is no data regarding any foreseen large scale

investments at least until the middle of the period (up to 5 years) that should

substantially influence the water demand by industrial users.

FORECAST FOR POPULATION INCOME 5.1.4.

Introduction

Income projections have a central role in planning of future water and wastewater

systems as they are the basis for macro-affordability assessments and are

determinative for the maximum value of investments. In addition, incomes are

important for the overall attractiveness of the region and influence directly internal in-

and out-migration.

Household income projections are dependent on the current household income level

and the predicted economic growth of the region. The “Guidelines for cost benefit

analysis of water and wastewater projects supported by the Cohesion fund in 2007-

2013” provide the following definition: “It is recommended considering household’s

disposable income growth as equal to GDP growth. As a result, current data collected,

split by income decile, will be projected using a growth rate equal to the GDP growth”.

The proposed approach is adopted in the master plan and included as part of the

applied methodology.

Methodology

Determination of the average household income in the service area is problematic as

settlements are spread across three administrative districts, which have different

income levels, reported by official statistical data. The following approximation

procedure has been applied to derive a common income value :

� Determination of the average household income level in 2011 for the serviced

area WSS - Kardzhali;

� Establishment of income projections for each of the districts using real GDP

growth, indicated in Table 5-2. Identical GDP growth rates have been used for



all districts as the analysis has demonstrated no significant differences at

regional and national level;

� Projected income is distributed in decile groups on the basis of NSI reported

distribution statistics;

� Income per capita is calculated on the basis of 2.8 people per household

throughout the reference period, despite the observed historical tendency for

larger households. This indicator is relatively stable and changes are slow and

insignificant and their influence on the calculation of the income is

insignificant.

Summary results

Forecast for household income within the serviced area are presented in Table 5-10.

Real income of the population of the serviced area is projected to increase up to 7,484

Euro (14,637 BGN) to 2038 but it remains app. 64.89% of the expected average

income in the country of 11,532 Euro (22,554 BGN).

Serviced area of

„WSS”- Kardzhali 3,147 3,653 4,301 5,404 7,484

Projected income is additionally split into decile groups on the basis of income

distribution statistics at national level (Chapter 2.3). Although income of the lower

three deciles is likely to evolve at a slower pace than the average income, which is

indexed fully to GDP growth, existing statistical data do not provide such justification26.

Consequently, real GDP growth is used for the projections across all income deciles.

Income decile 10 205.53% 6,467 € 7,508 € 8,840 € 11,107 € 15,382 €

26 Only 2-year time-series exist at the present moment (2009-2010) and income changes

appear to be random across deciles. No correlation can be isolated for such a short time period.

In addition time-series are both in the pre-crisis and crisis periods, making them incomparable.



5.2. WATER DEMAND PROJECTIONS

This subchapter gives the result of the water demand projections carried out on the

territory of Water Supply OOD - Kardzhali. It is based on information and

methodologies described in previous chapters:

• First, the current situation concerning the water demand in the considered

area, which is described in Chapter 3.

• Second, the methodology to establish the projections and the assumptions

made which are presented in section 4.1.1.

SUMMARY OF WATER DEMAND PROJECTION AT THE WSSC 5.2.1.

TERRITORY LEVEL

Based on the existing situation presented in Chapter 3, and based on the socio

economic projections carried-out in chapter 5.1, water demand projections are carried

out for the years 2016 (first year of operation for investments implemented in the

short-term program), 2021 (beginning of the medium-term program), 2028 (end of the

medium term program) and 2038 (end of the long-term program).

The table presented below is a summary of the water demand projection at the WSSC

territory level. It is therefore an aggregation of the data for all settlements of the

territory of the WSS operator. It doesn’t include the 227 settlements not served by the

WSS operator, totalling 17,534 inhabitants in 2011, for which few data is available

(however see Table 5-20 in chapter 5.2.2)

5.3. PROJECTED WASTEWATER FLOW

This subchapter gives the result of the wastewater flow projections carried out on the

territory of Water Supply and Sewerage OOD – Kardzhali. It is based on information

and methodologies described in previous chapters:

• First, the current situation concerning wastewater flow in the considered area,

which is described in Chapter 3.



• Second, the methodology to establish the projections and the assumptions

made which are presented in section 4.1.1.

In accordance with the Terms of Reference, the pollution load rate is set at 60 grams of

BOD5 per person per day. The “Population Equivalent (PE60)” of a settlement is

therefore the ratio of the pollution load (BOD5) produced at the settlement level in one

year to the individual pollution load produced by one person in the same time.

SUMMARY OF WASTEWATER FLOW PROJECTION AT THE WSSC 5.3.1.

Based on the existing situation presented in Chapter 3 and based on the socio-

economic projections carried out in chapter 5.1, wastewater flow projections are

carried out for the years 2016 (first year of operation for investments implemented in

the short-term program), 2021 (beginning of the medium-term program), 2028 (end of

the medium term program) and 2038 (end of the long-term program).

The table presented below is a summary of the wastewater flow projection at the

WSSC territory level. It is therefore an aggregation of the data for the 244 settlements

of the WSSC territory.

* It is not 100%, as no centralized sewerage system is envisaged for settlements with

less than 50 inhabitants.

For the 227 villages not operated by the WSSC, most of them have a population

below 50 inhabitants. For the others it would be pointless to make an evaluation

without specific enquiring on each case. These settlements would have to be covered

by the zoning study for application of centralized or autonomous sanitation when

relevant

SUMMARY OF DESIGN WASTEWATER FLOW AND LOAD 5.3.3.

For all the agglomeration above 2,000 inhabitants, the year with the highest “total

wastewater collected” is defined as the “design year wastewater flow”. It is selected

among the milestones 2011, 2016, 2021, 2028 and 2038. Similarly, the year with the

highest “actual pollution load collected” is defined as the “design year pollution load”.

Following the results of the option analysis presented in Chapter 4, a Wastewater

Zone (WWZ) is defined as a group of agglomerations or settlements the wastewater of

which is collected and disposed in the same WWTP. The summarised parameters for

each agglomeration as well as the aggregated data for each wastewater zone (if any)

are presented in the table below.

5.4. MACRO-AFFORDABILITY ASSESSMENT

AFFORDABLE TARIFFS AND PRICES 5.4.1.

Macro-affordability assessment is required in order to determine the viability of

proposed investments in water and wastewater systems and to establish realistic

limits on the maximum investment values. Macro-affordability is dependent on multiple



variables – type and timing of investments, projected operation and maintenance

costs, established and expected depreciation policies, sources of financing for the

investment (loans, grants, etc.). All these components are integral part of tariff

formation and thus influence affordability.

There are different approaches to affordability adopted at national and international

level.

Bulgarian legislation defines an affordability threshold of 4% of the average household

income at a minimum consumption of 2.8 m3 per member of the household27.

The Guidelines for cost benefit analysis of water and wastewater projects supported

by the Cohesion fund in 2007-2013 provide the following definition: “Total water and

wastewater charges including indirect taxes (VAT) should not exceed 2-2.5% of the

average household income (when calculated on the basis of an average per capita

consumption linked to the economic situation of such households). This limit could be

increased temporarily to reach a max of 4%, in case the financial sustainability of the

project is otherwise endangered”. The prices of WSS services within the territory of

the company are below the national average and according to NSI data on social

affordability of the price of WSS services by areas and regions for 2011, the average

price for: Kardzhali is 3.39 BGN/m3, for the country is 4.43 BGN/m3, for South Central

Region - 4.17 BGN/m3.Affordability thresholds are calculated at the projected current

levels of water consumption and presented in real 2011 values. The tariffs used to

evaluate macro-affordability are formed at a threshold of 4% of the average income of

the first three decile groups.

BGN) for domestic and industrial wastewater collection and disposal. The current

prices are below the projected at a threshold of 4% of the income of the 3rd decile.

EXISTING REVENUES AND COSTS 5.4.2.

According to the audited financial statements for 2011, Vodosnabdyavane i

Kanalizatsiya OOD Kardzhali has total revenues amounting to 3,497,000 EUR (BGN

6,841,000) and total costs amounting 3,483,000 EUR (BGN 6,813,000), thus ending

the year with a profit (before interest and taxes) amounting to 14,320 EUR (BGN

28,000).

The table below shows a more detailed presentation of the operating revenues and

costs for the period between 2009 and 2011.

No significant changes are observed in the cost structure. The largest relative share in

the cost structure by economic elements belongs to the remuneration costs (including

social insurance) – approximately 52% (1,874,000 EUR) of all the cost.

The costs of prime and raw materials and consumables amount to 755,180 EUR

(BGN 1,477,000) or approximately 21% of the costs by economic elements. They

include materials (262,800 EUR), fuels and lubricants (85,900 EUR), electricity

(356,370 EUR) etc.



The main groups in the costs of external services are water use fees (75,670 EUR),

repairs (37,840 EUR), communication services (17,380 EUR), insurances (11,250

EUR), other costs of external services (57,780 EUR).

Reported depreciation amounts to 576,230 EUR (1,127,000 BGN) for 2011 and is

relatively stable for the last two years due to the lack of large investment activities.

Maintenance costs are not reported separately in the financial statements of the

operator - they are allocated to the above-mentioned categories. However,

maintenance is very limited except for the costs of emergency repairs.

Costs are expected to remain relatively stable, if no investment activities are

implemented (‘without implementation of the project’ scenario) in the short-term plan

(the next 5 years). Costs at current prices will rise as a result of the projected inflation,

but no significant changes in constant prices for 2011 are expected. One noteworthy

exception are the costs of staff, which will be influenced by the real GDP growth. The

fuel and electricity prices can increase at higher rates in comparison with the inflation

taking into account the trends observed in the first half of 2012, however the historical

data does not provide enough evidence for such an assumption.

AFFORDABLE INVESTMENT PROGRAMS 5.4.3.

Affordability calculations are performed on the proposed investment program for a

reference period of 28 years. The recommended investment program specified in

detail in Section 6 of the Master plan lists all possible measures for the water sector in

Kardzhali but needs to be checked against the affordability criterion. Standard unit

prices along with prioritisation criteria have been established and used (described in

Chapter 4) in the development of the investment programme. The following

investment elements have been envisaged as necessary for the region in the short-,

medium- and long term periods

In addition, funds are allocated for each period for the preparation of feasibility studies (1% of investment costs), design (4%), supervision (5%), project management (3%) and contingencies (10%). The total value of proposed construction works is € 85,104,600 for the short-term period, € 97,347,800 for the medium-term and € 98,062,700 for the long-term period. A total of € 36,467,100 is envisaged for studies, design and supervision, and another € 28,051,400 are allocated for contingencies, producing a grand total of € 345,033,600 for investment costs of water Supply and Sewerage OOD – Kardzhali.

In the overall programme the biggest relative share is that of sewerage infrastructure investments which equals almost 68% of all investment activities. The short-term investment period envisages predominantly investments in the water supply infrastructure which is almost 51.38% of the total costs. In the medium- and long-term period the sewerage infrastructure costs amount respectively to 74% and 79% of the envisaged total investment costs.

Affordability estimates require the establishment of incremental operation and maintenance costs that will influence tariff formation and the ability-to-pay for water and wastewater services. Incremental operation and maintenance costs are calculated on the basis of the assumptions, listed in detail in Chapter 4, while a summary is provided below:

• Water supply – annual maintenance and operation costs as follows: Equipment and machinery (3% of construction costs). Water mains (0.15%). Distribution network (0.5%). Civil works (0.5%). Electricity (0.11 €/kWh);

• Wastewater discharge – annual maintenance and operation costs as follows:

Equipment and machinery (3% of construction costs). Main collectors

(0.20%). Secondary sewerage network (0.6%). Civil works (0.6%). Electricity

(0.11 €/kWh);

• Wastewater treatment plants – annual maintenance and operation costs of

4.5% (all inclusive).

In addition, the following distribution of construction investment costs has been

assumed in order to derive a realistic estimate of incremental operation and

maintenance costs.

Table 5-34 Distribution of construction investment costs

Pipes Civil works Mechanical and

electrical equipment

New wells 70% 30%

DWTP 55% 45%

New water mains 85% 15%

Pumping stations 60% 40%

WWTP 55% 45%

Main sewerage collectors 100%

Wastewater pumping stations 60% 40%

Sewerage network 100%

The methodology of affordability calculations involves several subsequent steps as

follows:

• Determination of the maximum possible revenues given the projected

consumption and the upper limit of tariffs at 4% of the average income of the

first 3 decile groups. If the envisaged investments are impossible to be

implemented and/or their implementation will be significantly limited under the

adopted threshold, one more scenario under an affordability threshold of 4%

of the income of households of the 3-rd decile has been examined. This

calculation does not include level of revenue collection as water operators are

not allowed to account for this category when proposing tariffs in front of the

Regulatory body. Revenues from institutional and industrial clients are also

included in order to fully simulate the income cash flow within the operator

despite the fact that they are not affected by affordability calculations;

• Projections for the existing operation and maintenance costs and

depreciations (“without the project” scenario). After a statistical analysis for

price changes against the average inflation, all operation and maintenance

costs are held at their current level in constant 2011 prices except for

personnel costs which increase in line with the real GDP growth.

• Projections for the incremental costs of new investments (“with the project”

scenario) for each of the investment periods. The above assumptions have

been used to calculate operation and maintenance costs for new investments.

Due to the larger share of investments in water supply systems in the

medium- and long-term, existing costs have been reduced because of

efficiency improvements and reduction of losses;

• Projections for the incremental depreciations as a result of the new

investments (“with the project” scenario) for each of the investment periods.

The following assumptions have been used: 50 years useful life for pipes; 45

years useful life for civil works; 10 years useful life for mechanical and

electrical equipment. 30 years useful life for all other infrastructure elements.

All assets which reach the end of their useful life are replaced and

depreciations are calculated on the replacement value. Different scenarios

can be assumed for depreciations – equal depreciations for each of the years

in the reference period, increasing depreciations, partial depreciations (as

required by the rules of current Operational Programme). etc. Three scenarios

have been simulated for the territory of Kardzhali – full linear depreciation,

partial 50% linear depreciation and without accounting for depreciation of the

new assets.

• Accounting for the sources of financing – EU and national grant funding,

municipal co-financing, loans from national or international financing



institutions. 2 scenarios have been calculated – 100% grant financing and

90% grant financing / 10% loan financing. It has to be noted that if loans are

taken by the municipality, currently there is no legal way of integrating them

into water and wastewater tariffs. However, the affordability analysis assumes

that loan payments are included as tariff formation element (e.g. loan paid

back by the water company);

• Determining the difference between overall revenues and overall operation

and maintenance costs in all possible scenarios. In case the difference is a

positive number, investments are considered affordable as the operator will

generate enough revenues from affordable tariffs to cover all operation and

maintenance costs (including replacement of assets with shorter life span). If

the established difference is negative, then investments are not affordable and

an investment limit is provided for each of the periods.

The maximum possible revenues from domestic and non-domestic consumption at an

affordability threshold of 4% of the average income of the first 3 decile groups and 4%

of the income of the 3-rd decile are presented below. Considering the current (2011)

operating and maintenance costs of 3,619,000 it is obvious that using tariffs under a

threshold of 4% of the first three decile groups would endanger the financial stability of

Water Supply and Sewerage OOD – Kardzhali. Due to this reason a scenario

including maximum affordable tariffs for WSS services under a threshold of 4% of the

income of the 3-rd decile has also been envisaged. Considering the water losses

reaching up to 62% in 2011 the calculations have been made with gradual reduction of

losses up to 25% in 2038.

Incremental O&M costs for new investments except for depreciations for each of the

investment periods are calculated on the basis of the described assumptions and

distribution of funding between pipes / civil works / mechanical and electrical

equipment. Full operation and maintenance costs need to be calculated in water and

wastewater tariffs. CAPEX depreciation costs include only incremental depreciations

resulting only from new investments and do not account for existing depreciations.

Existing depreciations, including on-going investments, are equal and included in both

“without the project „and “with the project” scenarios. Periodic maintenance costs are

calculated in the operating costs on the basis of the assumptions listed in Chapter 4 of

the Master Plan.

Three possible scenarios are calculated with regard to depreciations: 1) linear 100%

depreciations on new investments and replacement costs, 2) linear 50% depreciations

on new investments and replacement costs and 3) 0% depreciations on new

investments and replacement costs.

Other scenarios may also be looked at, e.g. progressively increasing depreciations.

However, these are currently limited by the conditions imposed by the regulatory body.

Partial loan financing can be considered as a complement to different depreciation

scenarios. Currently, two scenarios are elaborated – full grant financing and 10% own

co-financing by means of a loan payable for 10 years with a 7% interest rate but these

can be easily extended with various financing alternatives. It has to be noted that the

assumption of using municipal loan payments in tariff formation is not realistic at the

current moment because it does not represent an expenditure of the water company

and consequently it cannot be justified before the Regulatory authority. Nevertheless,

this assumption is worth considering in case of legislation changes.

Identifying the affordable investment amounts depends strongly on the type of

investments and the resulting depreciation and operation and maintenance costs.

Using an affordability threshold of 4 % of the average income of the first 3 decile

groups will seriously affect the investment realization options of Water Supply and

Sewerage OOD – Kardzhali even under a scenario of 0% depreciation of new assets.

The net cash flows resulting from the affordability calculations are presented below.

Regardless of the reasons stated above, Table 5-40 shows also the results of the

financial affordability calculations under an affordability threshold of 4% of the average

income of the first 3 decile groups.

The financial flows analysis shows that the options for implementation of the

investment programme are realistic in a scenario without including depreciation of new

assets, reduction of investments and with tariffs conforming to an affordability

threshold of 4% of the average income of the first three decile groups.



In all cases, the investment is considered affordable if revenues generated at tariffs

set to 4% of the average income of the first 3 deciles are sufficient to cover the full

O&M costs and full depreciation of assets.

The analysis of the results shows that the implementation of short-term programme in

the beginning of the period accumulates shortage, which allows for approximately

45% implementation of investment proposed (EUR 47,105,300). In case of partial

depreciation of new assets (30% and 100% grant funding) and the income of the

lowest-income three decile groups, accumulated shortage cannot be eliminated

without reducing the amount of the investment programme. With partial (30%)

depreciation, the affordable amount of investments represents about 25% of the

planned investment components or an approximate value of € 26,169,700. In case of

full depreciation, the possible investment options are very limited and the accumulated

shortage may lead to deterioration of the company’s financial stability.

The medium-term programme amounting to € 119,737,800 can be implemented at

75% (EUR 89,803,400) without accounting for depreciation and with 100% grant

funding of new assets and a threshold of 4% of the average income of the first three

decile groups plus 45% implementation of investments in the short-term programme.

In case of partial depreciation (30%), approximately 28% may be implemented or EUR

33,526,612 in case the short-term programme is reduced by approximately 55%.

If the short-term and medium-term programmes are implemented, the long-term

programme is affordable in a scenario of 0% co-financing and without accounting the

depreciation of new investments. If the short-term and medium-term programmes are

reduced – by 55% for the short-term and 25% for the medium-term programme (as

described above), the long-term programme can be implemented at approximately

43% (EUR 51,865,400) with partial (30%) depreciation of new assets. An option of full

depreciation and 100% grant funding significantly reduces the possibilities for

realisation of planned investments and this requires the implementation of measures

for optimizing the costs.

The table below present the amount of possible investment costs in the three

investment programmes with an affordability threshold of 4% of the average income of

the first three decile groups and in a scenario of partial depreciation of new assets

and 100% grant financing.

The identification of affordable levels of investments for all three investment periods is

highly dependent on the type of investments and the resulting depreciation and

operation and maintenance costs. Despite the complexity of the situation, it should be

noted that the time horizon of the three investment programmes is substantial.

Therefore, it is necessary to point out that the longer-term predictions are developed,

the greater their uncertainty. This is due to the fact that even seemingly small changes



in the external environment, such as degree of population increase / decrease or

economic development can lead to fundamental differences, if these changes prove to

be sustainable over time. For this reason, it should be considered that the values of

the short-term investment programme are more reliable than those in the medium-

and long-term programmes.

Nevertheless, the results of the macro-affordability analysis of investment

programmes lead to the conclusion that their full implementation requires to provide

options for using higher tariff levels, formed at a threshold of 4% of the income of the

third decile in certain periods. Thus, depreciation of new assets may be covered

without jeopardizing the financial stability of the operator.

An increase in the threshold for price formation of the service provided may put a

significant financial pressure on lower income household and result in lower tariff

collection rates.

Other affordability risks that might be identified include faster than the expected

depopulation, slower than predicted economic development in comparison with the

national average, changes in the income structure (more households with lower

income), etc.

Because of these reasons, appropriate incentive schemes need to be established for

lower income households so that the projects can be financially viable and

sustainable. This might include increasing block tariffs for water services and social

support for the economically deprived households and/or implementing different tariffs

for domestic and industrial consumers.



6. SHORT, MEDIUM AND LONG-TERM INVESTMENT PROGRAMME TO MEET WATER AND WASTEWATER DEVELOPMENT TARGETS

6.1. INVESTMENT PROGRAMME OVERVIEW

GENERAL APPROACH 6.1.1.

This chapter presents the short, medium and long-term investment programmes,

which include all the investment measures necessary for:

1) Achievement of full compliance with EU and Bulgarian legislation;

2) Implementation of the objectives set in the national water strategy.

The proposed investment programmes take into consideration the results of all the

Chapters described above. The main tasks performed in the chapters above and in

this chapter are as follows:

• Comparison of the existing situation with the national objectives and

strategies;

• Identification of all investment measures required for implementation of the

objectives and removal of existing deficiencies;

• Calculation of the investment costs;

• Evaluation of various options and identification of the least costly, most

affordable solution;

• Grouping of all identified investment measures in short-term, medium-term

and long-term investment phases;

• Prioritization of the investment measures defined in each phase;

• Description of the outcomes and benefits expected from the investment

measures;

• Assurance of financial viability of the proposed programmes, verification of the

sustainability of the programmes and the assessment of the risks related to

the programme implementations.

Reference is made to Chapter 4.1.3. “General Methodology for Phasing and

Prioritization” for a detailed description of the methodology and Chapter 4.1.2. “Unit

Costs”.

SUMMARY OF THE INVESTMENT PROGRAMME 6.1.2.

The table below presents a summary of the investment costs for all investment stages.

The calculated costs for the short-term programme amount to EUR 104,678,600 , the

costs for the medium-term programme are € 119,737,800, while the costs for the long-



term programme amount to € 120,617,200. The total investment costs for the entire

programme period amount to approximately € 345,033,600.

Table 6-1 Investment costs for all stages (in €)

Total investment costs 96,000,700 € 122,009,100 € 1 20,617,200 € 338,627,000 €

The following additional costs are included in the total investment costs: 1% for

feasibility studies, 4% for design, 5% for supervision, 3% for project management or

for supervision and control amounting to a total of €36,467,100 and another 10% of

contingencies amounting to a total of € 28,051,400.

The current prices of the services provided by Vodosnabdyavane i Kanalizatsiya OOD

Kardzhali are below the maximum affordable tariffs at a threshold of 4% of the income

of the first three decile groups, which allows to use the established threshold. Macro-

affordability analysis of the three investment programmes with an affordability

threshold of 4% of the average income of the first three decile groups indicates that

the implementation of the proposed investment components is most viable only in a

scenario without accounting depreciation of new assets, 100% grant funding and

reduction of investment costs in the short and medium term, as described in item 5.4.

The options for partial depreciation allows for limited implementation of investments

planned in all of the proposed investment programmes. In this context, there are risks

associated with a decrease in the quality of services provided by the Operator to

citizens, institutions and businesses. In this regard, it is possible to propose an option

for higher prices formed at a higher threshold in certain time periods in order to make

the proposed investments. This would ensure the financial sustainability of the

Operator.

Despite the outlined reasons, the investment components amounting to 85,104,600 in

short-term programme are feasible to approximately 45% in a scenario without taking

into account depreciation of new assets. The implementation of the programme

including 30% depreciation of new assets, allows for execution of 25% of the

proposed investments with the tariff formation threshold employed for calculations.

The medium-term investment programme is feasible at 75% without taking into

account depreciation of new assets and using a threshold of 4% of the income of the

3rd decile group. In case of 30% depreciation of new assets and reduction of the short-

term programme by nearly 55% (as described above), the amount of the investment

component is approximately € 33,526,612 or 28% of investments planned, Similar to

the short-term programme, the revenues generated at tariffs formed at a lower

threshold allow for implementation of limited investments in water and wastewater

infrastructure within the designated territory.



The investment component of the long-term investment programme amounts to €

98,062,700 and it is fully feasible if the depreciation is not taken into account. In 30%

depreciation (if the previous two investment programmes are reduced), and in an

affordability threshold of 4% the average income of the first three decile groups the

long-term investment programme is feasible at approximately 43% and the potential

costs amount to € 51,865,400.

The degree of implementation of the investment components depends entirely the

method of financing and the level of coverage of depreciation, operation and

maintenance costs. As noted the employed approach brings certain risks due to

declining and aging population, slow economic development and possible reluctance

to pay higher tariffs.

Besides the investment programme described below, the Consultant recommends

carrying out several studies or a programme, as follows:

Institutional studies

A set of institutional studies (and analysis of the effectiveness of territorial divisions)

should be conducted after the publication of the new Water Act which is currently

under preparation. These studies, which should integrate local, district and national

levels, must contain:

• analysis of services in terms of personnel and technical management

• analysis of the effectiveness of territorial divisions

• analysis on the possible merging of different WSS companies (publics,

private)

• analysis of results of settlement exchanges between different WSS

companies

• analysis of budget results regarding the actual rules applied by the Bulgarian

Regulator and the recommended European rules

These studies are not included in the investment programme and cannot be quantified

at this stage. The Consultant proposes this type of study because ambitious technical

investment programmes can only be effective if they are consistent with a high level of

service.

NRW reduction programme

The operators must have a policy management and meter replacement, based on age

(recommended maximum between 10 and 14 years), the efficiency of the metering

(water meter size should be suitable for the consumption of the subscriber) and the

quality of the installation and monitoring. The same policy should be conducted at the

level of the metering points on the external water supply system (the age of

replacement depends on the material). This is an important recommendation but is not

integrated because it is not possible to quantify it and since this programme should be

financed by the operators



Sludge management study

The Consultant recommends possible alternatives for sludge management in future

feasibility and design studies but also to initiate a specific study on undertaking actions

on national level with several pilot sites.

The abovementioned study includes several components:

• Analysis and proposed regulatory changes regarding Bulgarian sludge

management

• Assessment of the industrial situation on the pilot sites

• Assessment of the existing sludge management on the pilot sites

• Determination of potential agricultural uses for the pilot sites

• Future interaction with potential consumers

• Socio-economic measures and communications to educate the public

concerned

• Design educational courses

• Assistance in the implementation of contracts between operators and end

users of sewage sludge

The Consultant recommends integrating the reuse of treated water from WWTP to this

sludge management approach.

The Consultant recommends that one or several pilot sites should be selected on the

territory of ViK OOD Kardzhali.

Non-domestic wastewater management programme

The Consultant recommends the implementation of a comprehensive study, which

may include the following:

• General study at national level:

o Analysis and review of European legislation

o Analysis and assessment of the Bulgarian legislation

o Proposition of amendments

• General principles to be implement at local level:

Establish a specific contract between the WSS company and each wastewater sector

stakeholders, which may include the following:

o Descriptions of industrial processes and the nature of the effluent.

o Establishment of a point of continuous flow monitoring with periodic

return data to the WSS company and to the corresponding public

authorities (municipality, municipal council etc…)

o Implementation of a tracking point pollution control with periodic

return data to the WSSC and to the corresponding public authorities



(choice of parameters depending on the nature of the effluent, the

minimum COD, BOD5, total suspended solids, N, P)

o Discharge authorization with a description of the permitted effluent

quality parameters.

o Implementation of treatment before discharge in the wastewater

collection system with strict monitoring and periodic return data to

the WSS company and to the corresponding public authorities, if

necessary

6.2. SHORT-TERM INVESTMENT PROGRAMME

INVESTMENT COSTS 6.2.1.

The investment costs presented in the tables below are net costs excluding VAT,

constant price base 2011 in EUR.


The main problems in the external water supply systems are:

• 36% of the water sources are with expired water use permits;

• The SPZs are not established pursuant to Ordinance 3 from 16.10.2000.

• Water in some of the water sources does not comply with Ordinance 9 from

16.03.2001 on the quality of water intended for drinking and household

purposes;

• A large part of the treatment facilities is of low reliability;

• 50% of the water reservoirs and pumping stations were constructed in the

period between 1940 and 1988. The equipment and fixtures are obsolete and

technically old. The pumps are in satisfactory condition, but with high power

consumption and there are no spare parts;

• The external water mains of the systems amount to 93.06 km – built of steel,

asbestos cement, reinforced concrete and constructed between 1930 and

1980. A small part of the water mains is built of modern materials, constructed

after 1998 and in good technical condition, the share of pipes in terms of

material being 25% for the asbestos cement pipes, 69% for the steel pipes

and 6% built of modern materials. The majority of pipes is old and obsolete.

The leakages from compromised connections, corroded and deformed pipes

generate large water losses and create risks of drinking water shortage and

deterioration of water quality. Water mains do not have established

easements – difficult access and maintenance.

The main problems in the distribution networks are:

• The networks are of total length amounting to approximately 181.1 km – about

17% of polyethylene pipes with good indicators, 73% of asbestos cement



pipes and 10% of steel and galvanized pipes with expired operation period,

which is a cause for water losses along the network varying from 40 to 60%;

• The total number of failures in the systems for 2011 is 476 or 0.38 failures per

km;

• Service connections – over 16,675 service connections are built mainly of

galvanized pipes, whose operation period has expired;

• About 90% of the metering devices are over 10 years old.

The short-term programme includes investment measures aimed at:

• Elimination of the main deficits concerning the water quality and quantity;

• Increasing energy efficiency.

The approximate costs for the short-term programme – Water supply, amount to

€ 43,735,200 and include the following investment components:

• Rehabilitation and modernization of DWTP and the associated chlorination

plants;

• Implementation of chlorination at the pressure reservoirs pursuant to the

requirements of the regulations;

• Construction of the required regulating volumes for the areas experiencing

water shortage;

• Reconstruction of main external water mains that generate large water losses;

• Reconstruction of the water distribution network, parallel to the replacement of

the sewerage network, intended in the short-term programme;

• Reconstruction of facilities (pressure reservoirs, pumping stations and water

sources) aimed at the increase of energy efficiency and reduction of physical

water losses.

• Water supply zoning study for the settlements within Kardzhali District with a

population of below 2,000 PE. These studies will define the best options for

centralized or decentralized water supply.

• Rehabilitation of civil works and equipment as well as power supply to

Chlorination facilities to gravity-fed reservoirs /settlements of less than 2,000

PE/.

The following results will be achieved with the implementation of the envisaged

activities:

• Supplying sufficient quantity of quality drinking water to all consumers;

• Reducing the water losses occurring in some of the transmission water mains

in the following towns: Kardzhali, Momchilgrad, Krumovgrad, Ardino, Dzhebel

and the village of Benkovski.



The envisaged chlorination activities will affect the quality of the water supplied to

65,488 consumers.

The rehabilitation of obsolete water mains will decrease the risk of failures in these

sections and will ensure continuous water supply to about 65,488 residents.

The table below presents the summarized short-term investment costs for water

supply. A detailed list of all the investment measures is presented in the tables related

to the respective sections of Chapter 6 and in the diagrams showing the Sort-term,

Medium-term and Long-term Investment Programmes for the water supply network of

every town (drawings №№ 15,17,19,21,23,25).

Sewerage 6.2.1.2.

The analyses, based on the studies of the wastewater collection, disposal and

treatment infrastructure lead to the following conclusions concerning the current state

of the structures and facilities:

• The major part of the sewerage networks, where they have been constructed,

function as combined ones – collecting wastewater, industrial and storm

water;

• Very few of the villages have constructed sewerage network;

• A problem in all of the towns is the incomplete street sewerage network, which

leads to soil and groundwater pollution due to the wastewater disposal in old

absorption pits. There is a high health risk to the population. Cleaning costs

for the individual septic tanks are high and respectively there is a lower

number of subscribers serviced by the WSS operator.



• The condition of a large part of the existing sewerage network is poor –

insufficient diameters, small and reverse slopes, sewerage construction of low

quality, the speed of the wastewater movement is below the admissible

minimum and lack of local treatment facilities. There are areas with insufficient

depth, subsidence, infiltration. There are also compromised sections, where

failures occur very often due to the many years of operation. There are

clogged sewerage service connections as well as manholes with

compromised integrity or sealed lids. Some of the storm water overflows are

not constructed. There are sections whose routes are outside the roadway;

• There are no constructed WWTP on the territory served by ViK OOD-

Kardzhali and wastewater is discharged without treatment in rivers or other

water bodies. There is also a risk of floods – due to the insufficient capacity of

the existing sewerage network and surface drainage, in times of intensive

rainfall a part of the estates are flooded and the streets become impassable;

• Lack of data from infiltration measurements in the existing sewerage

networks.

To date, Kardzhali Municipality has an on-going project for the construction of a

WWTP and intercepting collector, expansion and reconstruction of the water supply

and sewerage network under OP “Environment”, whose implementation will solve the

main problems of the sewerage infrastructure and the tasks of the short-term

programme.

Currently, Momchilgrad Municipality has an on-going project for the construction of a

WWTP, reconstruction, modernization and completion of the water supply and

sewerage network, whose implementation will solve the main problems of the

sewerage infrastructure and the short-term programme measures will be implemented

in this agglomeration.

The requirements of Directive 91/27/EEC concerning the wastewater treatment for

agglomerations between 2,000 and 10,000 PE should be implemented by 2014.

The short-term programme includes investment measures aimed at:

• Construction of a WWTP and intercepting collectors for all agglomerations

with over 2,000 PE in order to ensure compliance with the Wastewater

Treatment Directive;

• Reconstruction of the already constructed but severely obsolete sewerage

network, in order to reduce the infiltration and eliminate other major

deficiencies, which will ensure efficient operation of the WWTP.

The approximate costs for the short-term investment programme – Sewerage, amount

to € 39,866,400 and include the following components:

• Construction of sewerage network in the residential quarters without one;

• Expansion of the sewerage network in agglomerations with over 2,000 PE –

Krumovgrad, Ardino, Dzhebel, Benkovski, in order to achieve about 90% of

connection rate of the population to the sewerage system;



• Reconstruction of the existing sewerage collectors of insufficient hydraulic

capacity that have been placed at small depth. This way the overloading of

the network will be avoided and the risk of flooding will be reduced;

• Reconstruction of sewerage network with expired operation period and large

infiltration – these are mainly sewerage sections constructed of concrete pipes

of small length (1 m) with a large number of problematic zones (the

connections between the pipes);

• Reconstruction of the existing sewerage collectors with reverse or lower than

the normatively permissible minimum longitudinal slope, as well as

reconstruction of collectors with impaired construction;

• Construction of Strom water overflows;

• Construction of new or extension of the existing main collectors in order to

connect new residential quarters to the WWTP;

• Construction of new intercepting collectors and WWTP for the following

agglomerations: Krumovgrad, Ardino, Dzhebel, Benkovski;

• Sewerage zoning studies for the small settlements, which are not connected

to a WWTP.


activities:

• Avoiding groundwater pollution and reducing to a minimum the risk to the

human health. Preventing the discharge of untreated wastewater in rivers and

water bodies;

• Increasing the connection rate of the population to the sewerage network to

90%;

• Improving the quality of the WSS services as well as improving the ecological

status of the environment;

• Reducing infiltration and achieving constant operation mode of the WWTP,

reducing operation costs for the treatment of the excessively diluted

wastewater;

• Preventing overloading of the sewerage networks, reducing the risk of floods

and soil and groundwater pollution;

• Preventing soil pollution and pollution of rivers and other water bodies with

untreated wastewater.

The table below presents a summary of the short-term investment costs for sewerage.

A detailed list of all investment measures is presented in tables to the respective

sections of Chapter 6 and in the drawings showing the “Short-term, Medium-term and

Long-term Investment Programmes” for the sewerage network of each settlement

(drawings №№ 28,30,32,34,36,38).

FINANCIAL AND ECONOMIC CONCLUSIONS 6.2.3.

Based on the results of the macro-affordability analysis developed in Chapter 5.4, it

can be concluded that if an affordability threshold of 4% of the average income of the

first three decile groups is applied, the planned investments will be implemented to a

largest extent (45%) in a scenario including depreciation of new assets. In case of

partial depreciation (30%), the amount of investments has to be reduced by nearly

75% in order to ensure the financial stability of the company. The investment

programme can be fully implemented by considering partial depreciation and

increasing the tarrif at a threshold of 4% of the average income of the first three decile

groups.

The projected tariff levels at 4% of the average income of the lowest income groups

are to reach up to 0.82 EUR/m³ in 2016 at average 2013 prices of approximately 0.56

EUR/m³ or an increase of nearly 46.4%. Such an increase in tariffs can make it difficult

for the low-income households to pay the bills for WSS services, which would not be

able to spend 4% of their income for water services. In order to ease the financial

pressure on the first three decile groups, it is necessary to consider options for

differentiated block tariffs according to the consumption rate and/or targeted financial

support to low-income population.

6.3. MEDIUM-TERM INVESTMENT PROGRAMME


The investment costs presented in the tables below are net costs excluding VAT, with



The investment measures included in the medium-term programme are aimed at:

• Increasing the efficiency – reducing non-revenue water (water losses), energy

efficiency etc.

• Rehabilitation and expansion of the water supply systems, ensuring

sustainability – rehabilitation and adaptation of the infrastructure.

The approximate costs for the medium-term programme – Water supply, amount to €

25, 360,400 and include the following investment components:

• Reconstruction of the remaining main external water mains and transmission

water mains;

• Reconstruction of the main water main branches in the distribution networks,

sectoring aimed at reducing leakages and operational management;



• Replacement of pumps and electromechanical equipment in the pumping

stations;

• Rehabilitation of water reservoirs and replacement of fixtures and pipe

systems;

• Improvement of water disinfection and decontamination systems;


activities:

• Reducing water losses in the transmission water mains for all of the

concerned water supplied zones;

• Reducing water losses in the external water mains to 25%;

• Reducing water losses in the distribution network and service connections;

• Optimizing the operation of the pumps, increasing energy efficiency of the

system and reducing electricity costs;

• Improving the condition of the water reservoirs;

• Reducing the risk of disinfection of poor quality or overdosing of the reagents

for disinfection.

Sewerage 6.3.1.2.

The medium-term programme includes investment measures aimed at:

• Expansion of the sewerage network in agglomerations over 2,000 PE –

Krumovgrad, Ardino, Dzhebel, Benkovski, in order to achieve about 100%

connection rate of the population to the sewerage system;

• Reconstruction of the connected sewerage networks in order to reduce the

infiltration and removal of other main deficiencies, which will ensure efficient

operation of the WWTP.

The approximate costs for the medium-term programme – Sewerage, amount to €

71,987,400 and include the following investment components:

• Completion of the sewerage network in the residential quarters without

As in the previous programme, the implementation of medium-term investments at an

affordability threshold of 4% of the income of the first three decile groups allows for

implementation of 75% of the proposed investments in a scenario without depreciation

of new assets and in 45% implementation of the investment component in the short-

term programme. If the short-term programme is reduced by nearly 55%, the

affordable investment component in the short-term programme amounts EUR

33,526,612, (28%) in a scenario of 30% depreciation of new assets. Setting a higher

level of depreciation costs is associated with a minimum increase of tariffs of up to

4% of the income of the third decile in combination with an increase of tariffs for

industrial consumers.

It is expected that the tariff will reach 0.97 EUR/m3 in 2021, which is approximately

0.41 EUR/m3 higher than the current one. Considering the income of the population in

the designated territory, such a price of WSS services will put substantial financial

pressure on the first two lowest income groups for which additional measures should

be envisaged in order to ease their financial situation, apart from the ones proposed in

the short-term programme.

6.4. LONG-TERM INVESTMENT PROGRAMME


The investment costs presented in the tables below are net costs excluding VAT, with



The investment measures included in the long-term programme are aimed at:

• Increasing efficiency – reducing non-revenue water (water losses), energy

efficiency etc.

• Rehabilitation, reconstruction and expansion of the water distribution mains of

the water distribution systems concerned by the abovementioned

programmes, which ensure sustainability – rehabilitation and adaptation of the

infrastructure.

The approximate costs for the long-term programme – Water supply, amount to €

20,929,700 and include the following investment components:

• Reconstruction of the distribution networks – replacement of asbestos cement

and steel pipes;

• Measures concerning the reduction of water losses including Active leakage

control, Pressure management etc.;



• Replacement of pumps and electromechanical equipment in the pumping

stations;

• Rehabilitation of water sources and replacement of fixtures and pipe systems;

• Updating the SCADA system for management and control.

The implementation of the envisaged activities will achieve the following results:

• Eliminating the risk to the health of the population created by the use of

asbestos cement water mains – a large part of the water supply infrastructure

will be replaced;

• Reducing water losses in the distribution network to 25%;

• Optimizing the operation of the pumps, increasing the energy efficiency of the

system and reducing electricity costs;

• Rehabilitation of water reservoirs.

The table below presents the summarized long-term investment costs for water

supply. A detailed list of all investment measures is presented in Table 6-16 and in the

The implementation of the long-term investment programme depends largely on the level

of implementation of investments within the previous two periods. If investments in the

first two periods are reduced, long-term investments will be fully implemented in a

scenario without depreciation of new assets. Partial depreciation allows for

implementation of 43% (EUR 51,865,400) in case the first two programmes are reduced.

The implementation of planned investments in a scenario of full depreciation leads to

funds shortage jeopardizing the financial stability of the Operator.

With such implementation of investments, the tariff levels are expected to reach 1.22

EUR /m3 in 2028 and nearly 1.68 EUR /m3 in the end of the period when using an

affordability threshold of 4% of the average income of the first three decile groups

In addition to the computational approach used to determine the socially affordable

investments, all investment scenarios should take into account some additional risks

identified above, such as faster than expected decline in population, aging of population,

slower than expected economic development in the designated territory in comparison

with the national average. These risks are difficult to quantify, and the study of their

influence will lead to countless scenarios. However, the implementation of any future

investment plan requires careful consideration of these options before the actual

implementation.



7. ENVIRONMENTAL ASSESSMENT

7.1. ENVIRONMENTAL ASSESSMENT PROCEDURE

Environmental Assessment (EA) of plans and programmes is a preventative tool to

evaluate the potential significant impacts on the environment, resulting from the

implementation of plans and programmes at national, regional and local levels. The

assessment is carried out simultaneously with their development, i.e. the approach aims

to integrate processes. EA execution is fully consistent with statutory national procedures

for preparation and approval of plans/programmes and the authorities responsible for

their endorsement should conform to EA statement.

EA gives a notion of the expected changes that will occur in the environment as a

consequence of the performance of the investment intentions, set out in plans and

programmes.

The goal is to provide a high level of environmental protection by determining the

expected impact of the activities covered by the strategic planning.

The Environmental Assessment procedure is described in Appendix 7-1.

7.2. ENVIRONMENTAL ASSESSMENT OF THE REGIONAL WATER AND

WASTEWATER MASTER PLAN OF THE DESIGNATED TERRITORY OF

VIK OOD - KARDZHALI.

For the present Regional Water and Wastewater Master Plan of the designated territory

of ViK OOD-Kardzhali, information has been prepared for Evaluation of the need for

Environmental Assessment in compliance with para. 2 of Art. 8 of the Ordinance on the

terms, conditions and methods for carrying out an EA of plans and programmes.

Chapter 0 exposes the outcomes of the Study conducted on the territory ViK OOD-

Kardzhali within the framework of the Regional Water and Wastewater Master Plans in

Central Region of Bulgaria.

Chapter 3 presents the environmental features of the area, which may be affected by the

implementation of the Regional Water and Wastewater Master Plan.

Since the territory falls within the scope of the protected areas under Directive 92/43/EEC

on the conservation of natural habitats and of wild fauna and flora and under Directive

79/409/ЕЕС on the conservation of wild birds, the plan should undergo Compatibility

Assessment (CA) procedure, pursuant to Art. 2, para. 2 of the Ordinance on the terms

and conditions for carrying out a compatibility assessment of plans, programmes, projects

and investment proposals with the subject and objectives of conservation of protected

areas (SG. No 73/2007) of EPA.

The contracting authority of the plan i.e. the Ministry of Regional Development and Public

Works shall submit a written request to the competent authority for Evaluation of the need



for EA. This request shall contain all data on the implementation of the plan and the

investment programme, the stages that EA will undergo and the period for which the

programme will be prepared. The request shall be accompanied by possible impact of the

plan on the environment (CA), characteristics of the affected area and the expected

effects on the environment, map of the affected territory, plans and tables, etc.

The Regional Water and Wastewater Master Plan of the designated territory of ViK OOD-

Kardzhali is an environmentally sound plan, which includes all investment measures

necessary for solving the problems of the designated territory, related to ensuring:

• Needed water quantity of good quality for all purposes

• High quality of living space and environment

• Prevention of conditions causing health risk situations

• Conditions for sustainable development of water ecosystem and the biodiversity

in it.

It is guaranteed that all necessary requirements, related to impacts on protected

territories, protected sites and protected areas are observed. (The proposed investment

measures for wastewater treatment are favourable for the conservation of protected

areas).

Chapter 4 presents all strategic options for the development of the water supply and

sewerage systems as well as the technical, economic and environmental criteria for the

selected options, which are included in the investment programmes.

Chapter 6 contains a detailed description of the proposed short-term, medium-term and

long-term investment programmes, including all investment measures, required for

fulfilling the objectives, set out in the national water strategy and for achieving full

compliance with the European and national legislation.

In the implementation of investment measures in short-term, medium-term and long-term

plan, a system of measures will be applied for reducing to the rational minimum the

negative impact on environment.

Taking into account the proposed measures, the implementation of the individual sites,

included in the investment programmes is not expected to exert any negative effects on

the different environmental components during construction, operation and closure. None

of the protected territories, sites and areas is negatively affected.

The following main goals will be achieved:

• Supplying good quality water for all purposes to the population in the area of the

designated territory.

• Reducing drinking water losses in the system to 25%.

• Providing wastewater treatment consistent with the set requirements for water

body protection, increasing self-purification capacity.



• Creating conditions for sustainable development of water ecosystem and

biodiversity.

• Creating high living standard for the population in the area of the designated

territory and preventing health risk.

The expected impacts of the implementation of the Regional Water and Wastewater

Master Plan in the designated territory of ViK OOD-Kardzhali are as follows :

Expected impact on protected areas and protected zo nes :

Overall, the facilities envisaged for implementation in the Investment programme of the

Regional Master Plan of ViK OOD – Kardzhali are not expected to have any negative

impact and are compliant with the nature and purposes of the protected zones for

conservation of natural habitats and wild flora and fauna and for conservation of wild

birds. For every investment intention envisaged in the RMP the required EIA and CA

(compatibility assessment) procedures will be carried out during the preparation stage of

the feasibility studies and all of the measures and conditions set out in the respective

Decisions of RIEW Haskovo and RIEW Smolyan will be observed and performed during

its implementation (depending on the location of the sites, included in the investment

programme).

Expected impact of Water Supply part of the Master Plan:

Currently, drinking water supply within the boundaries of the designated territory of ViK

OOD-Kardzhali relies on surface water (Borovitsa dam- water body in good condition)

and groundwater. Water supply systems are not optimized. The large volume of

abstracted water is due to the substantial volume of non-revenue water, caused by

obsolete water supply facilities (large number of water leakages). By implementing the

Master Plan measures, such as rehabilitation of equipment, the percentage of non-

revenue water will be reduced to 25%.

The deviations from the regulatory requirements for drinking water at some of the

consumers are mainly caused by the obsolete parts of the water supply networks and

treatment equipment. Master Plan measures have been proposed in order to ensure

drinking water quality in the whole designated territory. To optimize water abstraction,

water use permits will be issued and Sanitary Protection Zone (SPZ) will be established

for all water sources used for water supply in accordance with Ordinance 3 of

16.10.2000. To provide optimal disinfection and distribution of drinking water to the local

population, the old and asbestos cement pipelines as well as the obsolete water

treatment equipment will be reconstructed. Finally, high electricity consumption will be

reduced through rehabilitation of water supply pumping stations.

As a first investment priority the RMP includes appropriate measures to solve the

problems with drinking water quality in all of the settlements, where permanent and

frequent deviations from the permissible levels are observed, regardless of the size of the

settlement and its population.



Expected impact of Sewerage part of the Master Plan :

The project area encompasses the territory of Kardzhali District: Ardino Municipality: 52

settlements; Dzhebel Municipality: 48 settlements; Kirkovo Municipality: 73 settlements;

Krumovgrad Municipality: 80 settlements; Kardzhali Municipality: 118 settlements;

Momchilgrad Municipality: 49 settlements; Chernoochene Municipality: 51 settlements.

The territory, served by ViK OOD-Kardzhali is located in the southern part of the country,

falling within South Central Planning Region and occupies 3,209.1 square metres with a

population of 152,808 inhabitants (NSI, 2011 Census).

Currently, a few settlements have sewerage systems (to a different extent). There are no

WWTPs. Polluted domestic and industrial wastewater is discharged into the receiving

bodies, thus creating conditions for health and environmental risk. The on-going project

for WWTP of the agglomerations of Kardzhali and Momchilgrad with approved funding

are to be implemented. For the agglomerations of Krumovgrad, Ardino, Dzhebel,

Benkovski, there are projects submitted for evaluation and approval.

The existing wastewater networks in most of the settlements are in poor condition. A

major part of the wastewater networks have reached the end of their service life. Sewer

pipes are old, obsolete, demolished, clogged and feature small diameters and insufficient

hydraulic capacity. Some sections of the sewer branches have reverse or low gradients.

A large number of streets have no sewer branches. There are unauthorized discharges

which are inconsistent with the European Directives.

The short-term, medium-term and long –term investme nt programmes, included in

the Plan envisage:

• Extension and reconstruction of the sewerage network.

Construction of modern WWTPs for settlements with over 10,000 PE as well as

for settlements of between 2,000 and 10,000 PE within the designated territory.

• Updating of Network Information Systems

• Supply of equipment for surveillance, maintenance and operation of sewerage

systems

• Construction of wastewater pre-treatment facilities for industrial companies,

connected to the sewerage systems of the settlements.

By implementing the Master Plan measures, the percentage of infiltration will decrease

significantly, which will lead to optimization of wastewater system performance. Finally,

high electricity consumption will be reduced through rehabilitation of wastewater pumping

stations.

Conclusion:

Information has been prepared on the Evaluation of the need for Environmental

Assessment of Regional Draft Water and Wastewater Master Plan of ViK OOD -

Kardzhali corresponding to the level of detail of the plan or programme and the methods

used for assessment. The information includes as follows:



- Description of the main objectives of the plan and the relation to other relevant

plans and programmes;

- The current status of the components and factors and their eventual development

without applying of the plan or programme;

- The environmental characteristics of territories that may be significantly affected,

- The existing environmental problems which are identified at different levels, and

related to the plan, including those concerning areas of specific environmental

importance;

− The objectives for environmental protection at national and international level,

regarding the plan and the way these objectives and all environmental

considerations have been taken into account during the preparation of the plan;

- Possible significant impacts on the environment including components and

factors and connections between them, the measures envisaged to prevent,

reduce and completely remove any adverse effects on the environment due to

the implementation of the plan or programme.

Pursuant to Decision N-EO 63/2013 of the MoEW concerning the RMP of ViK OOD-

Kardzhali no Environmental Assessment is required as its implementation is not likely to

have any significant impact on the environment and human health. The Final RMP has

taken into account all of the conditions set out in the Decision

Feasibility studies will be prepared for investment projects, included in the RMP of ViK OOD-Kardzhali, the possible involvement of water bodies will be determined at this stage and the respective measures will be taken before the Basin Directorates for Water Management in East Aegean Region for Basin Management to obtain the relevant permits.

During the preparation stage of the feasibility studies for the investment projects

envisaged in the RMP, their Contracting authorities will prepare a Plan of measures to

prevent, reduce or eliminate the negative environmental impacts during the

implementation of the projects and will coordinate it with RIEW –Haskovo and RIEW-

Smolyan, depending on the location of the sites, included in the investment programme of

the RMP.

Rigorous control will be conducted during the implementation of the RMP of ViK OOD-

Kardzhali in order to ensure compliance with the measures set out in the RBMP in East

Aegean Region from Chapter 7 Programme of Measures for Achieving the Objectives for

Environmental Protection of the RBMP of EARBD.
