1.1 BACKGROUND
1.2 OBJECTIVES OF ESA
The uncontrolled discharge of raw wastewater into the irrigation and drainage system
and on land has severely impacted the environmental, health, social and economic
conditions of Tikrit. From environmental and health aspects, the accumulation and
improper discharge of wastewater resulted in insect proliferation, soil contamination
and pollution of water bodies including the Tigris River (Al-Rawi, 2005, Al
Jebouri&Edham, 2012).
The main objective of a wastewater treatment plant (WWTP) is to protect the
environment from pollution as raw wastewater contains pathogens and high levels of
pollutants (such as total nitrogen, total phosphorus, BOD, fecal and total coliforms),
which, if not management and treated properly, can lead to water and soil quality
degradation as well as serious public health risks and diseases.
In addition to its public health and environmental benefits, the installation of wastewater
collection and treatment infrastructure is anticipated to provide economic benefits,
making Tikrit city more attractive for future residential and commercial development.
The main objectives of this ESA are to:
Identify relevant laws, polices and guidelines relevant to the proposed project;
Describe baseline environmental and socioeconomic conditions within the study area;
Identify the significant environmental and social impacts associated with the rehabilitation of the wastewater treatment plant;
Analyze alternatives to the proposed project;
Propose mitigation / enhancement measures for the identified impacts whenever possible;
Facilitate informed decision making, including setting the environmental terms and conditions for implementing the proposed project;
Develop a plan to monitor the identified impacts and their associated mitigation measures.

The wastewater treatment plant under the current assessment was designed and
constructed in the 1980s to serve Tikrit city. Its average wastewater influent flow of the
WWTP was estimated at 20,000 m3/day to serve a population of 80,000 persons. The
treatment plant stopped operation after ISIS attacks in Tikrit. Several units of the
treatment plant were blown up and destroyed. The following Figure 2-1 shows the
current situation of the WWTP. Moreover a satellite image of the current WWTP is
shown in Figure 2-2.

2.2.3 Process Description
Wastewater Reception
Wastewater reaches the plant via two force main sewers 500 mm diameter each.
There is a by-pass chamber used to overflow in emergency cases. The fine screens
were not considered in the original design of the plant as the designer considered the
available screens in the town pump stations which pumped the wastewater to the
WWTP as adequate. However, in the rehabilitated treatment plant, fine screen with
small openings (6mm) will be installed upstream the extended aeration tanks to
enhance the biological activity of microorganisms.
Aerated Grit & Grease Removal
In the Aerated Grit & Grease Removal Basins, the grit is settled at the bottom of the
grit channel while the grease is floated on the surface of the grease channel by the aid
of aeration across the length of the basin. The travelling bridge skims the grease off
the surface of the grease channel and dumps it to the grease sump located at the end
of the channel. Similarly, air lift grit pump mounted at the travelling bridge pump grits
to a cyclone for grit classification. Dewatered grit is then collected in containers to be
disposed of to a sanitary landfill while the degraded water is sent to biological treatment
units by gravity.
Aeration Tank
Wastewater free of coarse materials, grit and grease flows into two mixing chambers,
where the screened wastewater is mixed with the return activated sludge (RAS). The
mixture (WW+RAS) from each mixing chamber passes to a distribution chamber in
which the flow divides into three channels, each feeding into aeration tank by
overflowing the four weir gates distributed along the tank length.

Activated sludge process with 15-hour retention time is employed for the biological
treatment of wastewater. By well acclimatized microorganisms in this basin, a high
percentage of the pollution load is converted mainly to water and CO2 – classical
aerobic biological degradation. Necessary oxygen is transferred to the mixed liquor by
the air supplied by the surface aerators mounted on concrete floors supported by
concrete columns. Each aeration tank is equipped with four aerators each driven by a
30hp motor. Aeration rate is controlled by continuous monitoring of dissolved oxygen
and redox potential in the basins and adjusting the effluent weir to control the depth of
submergence of the aerators which is directly related to their aeration capacity.
Mixed liquor from the aeration tanks gravity flows to the second distribution chamber
equipped with sluice gates. This structure facilitates the even distribution of mixed
liquor to the clarifiers.
Sedimentation Tank
Each train process includes two clarifiers with circular horizontal flow. The diameter of
each tank is 22m. The mixed liquor suspended solids reach the tank at its central well
among a distribution chamber provided with gates to control the flow. The diameter of
incoming sewer is 600mm. The clarified water leaves the overflowing V-notch weirs
located along the tank perimeter, while the accumulated sludge in the bottom inverted
cone moves to the RAS & Waste Activated Sludge (WAS) pump station; the flow of
drawn sludge is controlled by a manually operated telescope valve. The tank is
provided with a rotating bridge supported at the center of the tank and moved on rubber
tires along the top of the tank wall. Each tank is provided with a complete system to
remove accumulated sludge and scum
Sludge Drying Beds
The settled sludge is sent to the combined sludge pump station over the telescopic
valves of the clarifiers. From this pump station, WAS is carried by a pipe to the drying
beds while the RAS is carried by another pipe to mixing chambers upstream the
aeration tanks. The filtrates of the drying beds and washout effluents are sent back by
gravity to a small washout pump station installed adjacent to the receiving chamber.
The two submersible pumps will be responsible for lifting the collected wastewater to
the receiving chamber.
Chlorination
The effluent of Final Clarifiers reaches the Chlorine Contact Tank by gravity, at the
inlet of which gas chlorine is injected into the wastewater for disinfection. Gas chlorine
(the disinfectant chemical) is injected by an automatic chlorinator, which adjusts the
required amount of chlorine according to the current flow rate of treated water. The
disinfected plant effluent is discharged to the receiving channel by gravity.

Wastewater Discharge Outfall
The treated wastewater will be discharged into Tigris River though a 15.09-km outfall
of 800 mm diameter Figure 4-2. The outfall is in good condition, thus no rehabilitation
activities are anticipated.

2.2.4 Rehabilitation Activities
The determination of the required civil works to rehabilitate any project, aged or
exposed to damage, requires a comprehensive assessment of the project in its current
status. For this purpose, a team of engineers with a good experience in the field of
wastewater treatment (design and construction) visited the site and started the
assessment. The following Table 2-2 represents major structural, mechanical and
electrical works that are required for each of the treatment process in order to bring
back the WWTP to work. It is worth mentioning that the administration building, power
plant unit, electrical network, internal roads and walkways, lighting system and the
surrounding fence are totally or partially damaged. Accordingly, new units must be
designed and constructed in order to replace all the destroyed parts. The rehabilitation
and construction phase will extend over a period of eight months, such that 30 workers
will be onsite in order to complete the assigned work.
Figure 2-5 on the following page presents the layout of the WWTP after rehabilitation
works have been completed.

3.1 PHYSICAL ENVIRONMENT
This chapter describes the different aspects of the affected environment, commonly
referred to as Baseline Conditions. Determination of the environmental baseline
involves description of conditions existing at present from which subsequent changes
can be predicted and subsequently monitored and managed. The section is divided
into the Physical Environment, Biological Environment and Socioeconomic
Environment.
3.1.1 Climate
Due to the relatively consistent topographic and geographic features in Tikrit, climatic
conditions do not vary considerably within the city. The average annual temperature in
Tikrit is about 21.0 ºC Figure 3-1. As for the wind direction, the prevailing wind
directions in that part of the country are northwesterly and westerly, representing on
the average, 44% of the times Figure 3-2. Rainfall in Tikrit city influenced by the
extension of the Mediterranean climatic conditions, with the rainy season between
November and April. The average annual rainfall recorded at Tikrit gauge station is

3.2 BIOLOGICAL ENVIRONMENT
3.1.2 Topography
The City of Tikrit is located at the right bank of Tigris River to the north of Samarra.
Geographically, this is the northern frontier district of Iraq. The land is still somewhat
undulating; the old town was built on a group of hills, one of which beside the river,
stands the modern town. The average elevation in the area is between 53-56 meters
(above mean sea level).
3.1.3 Surface and Groundwater Resources
The main source of surface water within the project area is the Tigris River. The source
of this river is located in eastern mountains of Turkey and flows into Iraq along its
northwestern borders. Currently the water quality of the Tigris River is degraded due
to several anthropogenic sources of pollution such as the direct discharge of raw
wastewater.
According to the Environmental and Social Management Framework that was
conducted for Tikrit, Al- Dour, Al-Alam and Al Dhuluiya located in the Salah Al-Din
Governorate, there are no specific aquifer found in the area. Moreover, the nearest
water table to the surface is more than 100m away. As such, the issue of ground water
contamination is not an issue within the project site (ReFAATO,ND).
3.2.1 Ecological Regions (Climate)
An ecoregion (ecological region) is an ecologically and geographically defined area
that is smaller than an ecozone and larger than an ecosystem. Ecoregions cover
relatively large areas of land or water, and contain characteristic, geographically
distinct assemblages of natural communities and species.
The Project Area in Tikrit is located in a combination of three ecological regions. These
regions are described below.
3.2.1.1 Mesopotamian Shrub Desert
This ecoregion represents a transition zone between the vast deserts to the south and
the steppes to the north. The climate is hot and dry. The topography is relatively gentle,
with no large mountains. Elevations of more than 1,970 feet (600 m) are found at the
eastern edge of this ecoregion, but to the east into the Tigris and to the west Euphrates
valleys, the elevation falls to less than 328 feet (100 m). Shrubby rock-rose species,
and woody, dwarf shrubs grow. Both humans and wildlife tend to congregate around
the few wetland and river areas in the region. Reeds and rushes grow in the wetland
areas, while aspen and tamarisk trees grow along river channels.

3.2.1.2 Arabian Desert and East Sahara - Arabian Xeric Shrub Lands
This is the largest ecoregion of the Arabian Peninsula, stretching from the Yemeni
border to the Arabian Gulf and from Oman to Iraq.
Characteristic mammals include Arabian wolf (Canis lupus arabs), Cape hare (Lepus
capensis), striped hyaena (Hyaena hyaena), sand cat (Felis margarita), red fox (Vulpes
vulpes) and caracal (Caracal caracal).
The rare houbara bustard (Chlamydotis undulata) also inhabits this area, as does the
rare spiny tailed lizard (Uromastyx thomasi). Rainfall triggers fast growth of the annual
desert vegetation dormant within the dry period, as well as hatching of an “instant
crustacean” (Triops) that could be dormant for years.
This ecoregion boundary was formed using Zohary’s (1973) geobotanical map of the
Middle East. It corresponds to Zohary’s classified regions of Sahara-Arabian desert
vegetation of Anabasetea articulatae and Sahara-Arabian interior sand desert
vegetation of Haloxylo-Retametaliaraetami (including Haloxylion persiciarabicum).
3.2.1.3 Tigris-Euphrates Alluvial Salt Marsh
The aquatic vegetation of this ecoregion includes reeds, rushes, and papyrus, which
support large numbers of water-loving species. Water birds stop here while migrating,
and some even spend the winter in these marshes living off the lizards, snakes, frogs,
and fish. Water buffalo, two endemic rodent species, and several other mammals also
call these marshes home. A scientific survey of the ecoregion revealed that more than
79 species of waterfowl, including pelicans, flamingoes, and ducks, use this ecoregion
as their principal wintering area. This area may support more than two-thirds of the
wintering waterfowl in the Middle East. Unique to these wetlands are two species of
mammals; Bunn's short-tailed bandicoot rat and the Mesopotamian gerbil. Other
mammals found in this ecoregion include wolves, common otters, and a subspecies of
smooth-coated otter.
3.2.1.4 Ecosystems
An ecosystem is a biological environment consisting of all the organisms living in a
particular area, as well as all the nonliving (abiotic), physical components of the
environment with which the organisms interact, such as air, soil, water and sunlight.
The Project Area is broadly divided into the two following ecosystems.
3.2.1.5 Tharthar Lake and Tigris River Ecosystems
This ecosystem consists of Tharthar Lake and Tigris River. It also includes the artificial
Canals. This ecosystem demonstrates the elements and characteristics of a wetland
which are critical for migrating birds, both as rest stops on their migrations and as
19
Engicon
ESA for Al-Dhebaee WWTP Tirkit District, Salah Al-Din Governorate Environmental and Social Assessment Report
RevNo. 01/09/2019
winter habitat. Among the birds that depend on the fresh water of this ecosystem are
the speckled teals, lesser kestrels, and imperial eagles. Some resident desert birds,
such as the Houbara bustard, take advantage of intermittent stream areas (wadis) in
the area.
3.2.1.6 Desert Ecosystem
Because the desert steppe is not heavily populated by humans, some large vertebrates
have persisted there. These include predators such as wolves, Asiatic jackals, striped
hyenas, caracals, swamp cats, goitered gazelles, and wild boars. Other characteristic
species of this ecosystem are the Euphrates jerboa (similar to a gerbil) and the desert
monitor (a lizard).
3.2.2 Flora
Flora is the plant life occurring in a particular region or time, generally the naturally
occurring or indigenous—native plant life.
Vegetation may be described as very diffuse but fairly evenly distributed sand shrub
land, interrupted in some parts by near sterile inter-dune floors. Typical plants are
Calligonum crinitum on dune slopes, saltbush (Cornulaca arabica) and tussocks of
sedge (Cyperus conglomeratus). Other widespread associates are Dipterygium
glaucum, Limeumarabicum and Zygophyllum mandavillei. Trees are absent, except
around the outer margins, and are typically Acacia ehrenbergiana and Prosopis
cineraria in drainage lines and pans between dunes, Calligonum comosum is the
characteristic woody perennial, growing in windblown sand, with a succession of
annual herbs that grow after rain, of which Danthonia forskallii is the most common.
Great variety of herbs and shrubs grow in this region. Most belong to the sage and
daisy families: mugwort (Artemisis vulgaris), goosefoot, milkweed, thyme, and various
rhizomic plants are examples. There also are many different grasses.
Toward the riverside lowlands many other plants appear, including storks bill and
plantain (common names). Willows, tamarisks, poplars, licorice plants, and bull rushes
grow along the banks of the nearby Rivers.
There does not appear to be any evidence of sensitive flora at the project site and its
surroundings.
3.2.3 Fauna
Fauna is all of the animal life of any particular region or time. There are many resident
species, though the effect of large-scale of impacts on migrants and seasonal visitors
which were once numerous has not been fully determined. The lion, oryx, ostrich and
wild ass have become extinct in those areas. Wolves, foxes, jackals, hyenas, wild pigs,
20

3.3 SOCIOECONOMIC ENVIRONMENT
and wildcats are found, as well as many small animals, such as; martens, badgers,
otters, porcupines, and muskrats. Marcia's gazelle survives in certain remote desert
locations. Rivers, streams, and lakes are well stocked with a variety of fish, notably
carp, various species of Barbus, catfish, and loach. Moreover, in Salah Din
Governorate, different types of species that depend on large water bodies are present
within this area. This include Otters, Indian Crested Porcupines, and Peregrine Falcons
that are found along the Tigris River banks (MoE, 2014). However, there is no evidence
that the project site and its surroundings are home to any sensitive fauna.
3.2.4 Protection Status and Current Ecological Issues
Human impacts and threats are often concentrated in areas of permanent or semi-
permanent waters. These oases often endure high levels of human activity. Diversion
of water for human consumption, agriculture, and livestock (sheep, goats, and camels)
reduces the amount available for wildlife. Overgrazing, hunting, and over fishing are
also problems in portions of these eco-regions. Unfortunately, local extinctions are
witnessed of Canis Lupus, Oryx leucoryx, Hyaena hyaena, jackal (Canis aureus) and
honey badger (Mellivora capensis). Gazelle subgutturosa and G. gazella still survive,
though with very small populations and restricted ranges. The sand cat (Felis
margarita), Ruppell's fox (Vulpes rueppellii) and Lepus capensis are thought to be far
less numerous than they were.
3.3.1 Demographics
Before ISIS, Tikrit city had a total population of about 150,000 as for the year 2012.
According to the world population review, the total population decreased to 42,477 in
2018.
The main demographic indicators are:
According to the available statistics until 2014, population growth rate was 2.6%;
40% of the population is less than 15 years according to the statistics of 2012; and 56.9% are in the category between 15- 64 years;
69% of the population is in the urban areas however, 31% are in areas according to the statistics for 2014 (MOCHMPW, 2017).
3.3.2 Economy and Living Standards
According to the UNDP report on the Iraq living conditions, a high percentage of
households within Salahuddin Governarate described their financial status as “neither
poor nor rich when surveyed. Moreover, the unemployment rate of this governorate is
12-13% which falls under is the lowest rate group. As for the literacy rate, 50 to 59%
of Salahuddin Governorate population that are above 15 years are able to read and

write. Crowding was also assessed in this report, the results shows that 7-11% of
Salahuddin Governorate household has more than three persons per room (UNDP,
2005).
3.3.3 Agricultural Activities
Geographical conditions in Tikrit area are favorable for irrigation because of the
availability of water from Tigris. The construction of small dams and diversion weirs
supplemented by irrigation and drainage canals encouraged agricultural activities in
the area. However, no detailed information could be obtained on the extent or type of
agricultural activities practiced by the residents of the project area. The political and
sectarian violence dominating the area for a considerable time have affected normal
daily lives of the people as well as the agricultural activities.
3.3.4 Infrastructure
The following Table 3-1 represents the infrastructural services that are found in Tikrit.

3.3.5 Archeological Sites
The Forty Shrine in Tikrit is the oldest shrine in Iraq. It was destroyed in 2014 by ISIS.
However, the project site is distanced from any known site of historical and cultural
heritage. However, the chance findings are still possible.

4.2.1 OP/BP 4.01 Environmental Assessment
The objective of this OP/BP is to identify, prevent, and mitigate the potential adverse
environmental and social impacts associated with the implementation of a proposed
project. In the World Bank operations, the Environmental Assessment (EA) is
conducted in an effort to improve decision making, ensure that proposed project is
environmentally sustainable, and that affected communities have been properly
consulted. Moreover, the Bank classifies the proposed project into three main
categories. The classification is based on the location, type, sensitivity, and scale of
the project as well as the nature and significance of its environmental impacts. These
categories are as follows:
Category “A”: Significant negative environmental impacts are likely to occur as a result of implementing the proposed project. These impacts might affect an area broader than the project sites.
Category “B”: Potential environmental impacts are less adverse than those of Category “A” projects. These impacts occur within the project site and proposed mitigation measures can be designed and implemented more readily than Category "A" projects. As such, a preliminary EIA must be prepared.
Category “C”: Minimal or no negative environmental impacts are likely to occur as a result of implementing the proposed project. As such, an EIA is not required in this case.
This project falls under Category “B” as the majority of impacts are expected to be
localized and temporary.
4.2.2 Environmental, Health, and Safety Guidelines
The Environmental, Health and Safety (EHS) Guidelines are reference documents for
environment, health and safety for the establishment of a new project. These
documents contain achievable measures and performance levels for new industries
and facilities at feasible costs using existing technologies. Moreover, when host
country standards differ from the levels and measures presented in the EHS
Guidelines, the project must follow whichever is more stringent.
The following guidelines apply to the proposed project:

The following sections provide a narrative description of the anticipated impacts before mitigation measures are implemented during both the construction and operation phases of the project.
The majority of impacts resulting from the project will occur during the WWTP
rehabilitation phase. However, most of these impacts are temporary for the duration of
the works.
5.1.1 Water and Soil Quality
Contamination of surface water and soil as a result of improper solid waste disposal,
inappropriate discharge of wastewater, accidental oil and chemical spillages, and
diversion of contaminated rainwater runoff from the project site. Moreover, since the
water table at the project location is high, the impact on groundwater is insignificant.
However, proper management of the generated solid waste and wastewater along with
the proper handling and storage of chemicals must be implemented.
28
Engicon
ESA for Al-Dhebaee WWTP Tirkit District, Salah Al-Din Governorate Environmental and Social Assessment Report
RevNo. 01/09/2019
A detailed description of the sources of pollution along with the associated activities
are listed below:
Construction Wastewater
Major construction activities that lead to the generation of wastewater include:
Washing of machinery;
Concrete mixing;
Maintenance of heavy machines and vehicles that generates wastewater contaminated with oil and grease;
Excavation of the site thus generating runoffs contaminated with suspended solids, especially during rainy days;
Storm water runoff that contains high amounts of oil, grease and suspended solids
This wastewater might pollute nearby water bodies and soils if not discharged and
managed properly.
Domestic Wastewater
For a period of 8 months, 30 workers are needed during excavation and construction
of WWTP. Based on the average monthly water consumption of 1.91 m³/person/month
(dos Santos et al., 2015), it is estimated that 1222.4 m3 of water will be used for worker
hygiene during this phase. Assuming that 80% of fresh water consumption will end up
as wastewater, it is estimated that 977.92 m3 of domestic wastewater will be generated
during the entire construction and rehabilitation phase.
Accidental Spillage
Water and soil could be polluted as a result of accidental oil or chemical spills from the
equipment used for the rehabilitation of the WWTP. The spills may occur during
storage and re-fueling of diesel supplies for power generation, as well as using oil,
lubricants, anti-acids epoxy, during rehabilitation activities, and equipment
maintenance and operation. With the installation of the wastewater pipelines supply,
accidental spill of oils and chemicals could occur and contaminate soil layers. The spills
may also affect water quality of the already polluted Tigris River during the
rehabilitation of the WWTP.
Solid Waste Generation
Abundant volumes of solid waste will be generated from the rehabilitation activities of
the WWTP, including damaged concrete units, deposits, debris and sludge
accumulated on several process units, cement and their resulting empty bags,
electrical wiring, rebar, wood and piles of sand and dirt due to excavation.
Inappropriate waste handling and improper disposal practices of construction waste
29
Engicon
ESA for Al-Dhebaee WWTP Tirkit District, Salah Al-Din Governorate Environmental and Social Assessment Report
RevNo. 01/09/2019
may result in ground and surface water contamination due to leaching and runoffs,
hence, reduction in overall water quality. In addition, these materials could be directly
discharged into Tigris River as it is located 6.5 km away from the project site.
As for the accumulated sludge in the old units of the WWTP (tanks, channels and
media filter), this sludge has stabilized and all organic material and volatile suspended
solids had been removed due to the condition of drying for many years. Therefore, no
negative impact is anticipated by discharging the sludge into a sanitary landfill.
5.1.2 Air Quality
The machinery and vehicles used during the rehabilitation phase produce exhaust
emissions and gases that can temporarily affect local air quality. Moreover, exhaust
emissions will also result from the power generator that will be utilized during the
construction phase. In general, this exhaust contains particular matter, Benzene,
Toluene, Xylenes, Ozone, Nitrogen Oxides, and Sulphur Oxides, Carbon Dioxide and
Carbon Monoxide.
The removal of exploded and demolished units, movement and transportations
practiced by heavy machinery on the site, generate particulate emissions such as dust
that can also affect the local air quality. Dust emissions around the WWTP could disturb
the workers onsite. As the location of the plant is in a desert the hosted fauna will be
disturbed by the different construction activities and all the resulting emissions. Open
burning of solid waste or other material on site could release emissions accompanied
by toxins.
As for odor emissions during the rehabilitation phase, the improper handling and
disposal of solid wastes, especially the accumulated sludge and debris may lead to
odor emissions.
5.1.3 Noise
Noise will be generated during the rehabilitation activities of the WWTP. These
activities include transportation or delivery of raw materials, trucks carrying debris,
concrete mixing, drilling and excavation and plant construction. and operation of heavy
vehicle movement such as excavators. All these activities require heavy construction
machineries and equipment to be onsite. A list of major machineries and equipment
along with their noise levels decibels (dB) is shown in Table 5-2.
Table 5-2: Noise Levels Emitted from Construction Machinery and Equipment

As the nearest residential area is 4.5 km away from the project site, noise from the
rehabilitation of the WWTP will not likely disturb the town residents. However, it will
probably affect workers that are present onsite. Moreover, animals and birds that use
the area for foraging and breading might be affected. In any cases, noise levels are
highly dependent on the extent and duration of the construction activities and are
temporary and specific to the construction phase.
5.1.4 Use of Natural Resources
5.1.4.1 Water Consumption
Water is needed for different processes of the construction activities. It is needed for
concrete mixing, cleaning of tools and the used machinery, dust suppression, ground
works activities and for potential testing of the newly constructed supplies. Aside from
construction water consumption, the construction phase will also require the
consumption of water for domestic usages which was estimated to be 1222.4 m3
(Section 5.1.1). Water consumption in the construction site may be overused causing
overexploitation of water resources.
5.1.4.2 Energy Use
It is estimated that several generators will be installed and used on site for energy supply. Fuel and oils are needed for the generators and for operation and maintenance of machinery engines on the site. If generators and engines are left running without being used in any activity, overconsumption and depletion of fuel is predicted to occur. However, this impact is temporary and short in duration as the rehabilitation phase is expected to last 8 months.
5.1.5 Land Resources
The rehabilitation phase will not change the land use of the area since the old WWTP
is already constructed on that plot area and no additional land will be needed for the
rehabilitation. Thus, the proposed rehabilitation project will not affect the land use and
land cover of the area.
5.1.6 Flora and Fauna
Since the rehabilitation project is located in the desert which has sparse vegetation
areas on an already built up land, the impact of the proposed project will not affect the
31
Engicon
ESA for Al-Dhebaee WWTP Tirkit District, Salah Al-Din Governorate Environmental and Social Assessment Report
RevNo. 01/09/2019
flora significantly. As for the fauna, deserts usually host predators such as wolves,
Asiatic jackals, striped hyenas, caracals, swamp cats, goitered gazelles, wild boars,
jerboa (similar to a gerbil) and the desert monitor (a lizard). During the rehabilitation
phase, high noise and dust levels can disturb these animals. However, this impact is
temporary and is not likely to be significant.
5.1.7 Visual Intrusion
The project site landscape will not change as the WWTP structures already exists.
Moreover, the WWTP is already surrounded by a fence and is located away from
residential areas. As such the rehabilitation of the treatment plant will not cause visual
intrusion.
5.1.8 Socioeconomic Activities
The construction of the WWTP is an economic opportunity for the selected contractor
and their subcontractors. Local businesses may benefit from rehabilitation activities
through selling raw materials, equipment, machinery and goods and the project will
create 30 jobs and could hire engineers, technicians and workers from the local
population. This impact is, however, temporary and jobs will be discontinued as soon
as rehabilitation works are complete.
5.1.9 Traffic
During the construction process, activities and movement of truck excavators and
vehicles coming in and out of the construction site including transporting debris and
construction material, will increase traffic on all roads leading to the site (local and
agricultural roads). However, those roads are not used by residents as the project
location is far from residential areas (4.5 km away).
In addition, there is a potential risk of material falling from trucks during the
transportation of raw material and equipment to the WWTP site thus causing accidents
and leading to traffic congestion.
5.1.10 Archeological Sites
The project is not expected to result in any impacts on cultural heritage and
archaeological sites.
5.1.11 Health and Safety
Before the execution of the project clearance and removal of unexploded ordnance
(UXO) must be done from the Ministries of Interior (MOI). This is an important issue
since the WWTP was destroyed during armed conflict and has been left behind. The
32
Engicon
ESA for Al-Dhebaee WWTP Tirkit District, Salah Al-Din Governorate Environmental and Social Assessment Report
RevNo. 01/09/2019
5.2 IMPACTS DURING OPERATION
project site must be identified as safe in order to protect workers’ health and life. Based
on input from Tikrit Sewage Directorate, the site has been cleared of UXO by the army;
thus the site is considered safe for the workers who will undertake the rehabilitation
activities.
In addition, during high temperature days, workers could be exposed to heat stress
and dehydration. Accident and injuries to workers and the public may be caused by
transportation accidents, falls, electric shock, mishandling of machinery and other
rehabilitation and construction related accidents. The high noise generated from the
machinery could damage the hearing of the workers and dust generation from the
different rehabilitation and construction activities, movements and transportations may
cause respiratory problems for workers on site if appropriate personal protection
equipment are not being used.
In addition, impacts from Gender Based Violence (GBV) and Violence Against Children
(VAC) may occur during the rehabilitation phase. These impacts will most likey occur
due to labor mobilization and the unfamiliar cultural and social settings. Moreover,
social interactions between workers living in camps, surrounding communities, local
vendors and sellers can cause culturally insensitive behavior and relationships leading
to GBV, VAC and sexual harassment incidents (GGITR & GTGDR, 2018).
5.2.1 Water and Soil Quality
Wastewater Treated by the Plant
At the present, some portion of the wastewater generated by the unserved area in
Tikrit is collected in the cesspits while the rest is discharged into the nearby irrigation
and drainage canals by means of the existing primitive network and other primitive
short discharge lines. The present practice of collecting and storing the raw wastewater
in cesspits in the city is inevitably affecting the groundwater quality in the underlying
aquifers.
With the rehabilitation and operation of the WWTP, wastewater will be routed by the
networks directly from its source to the plant where it will be treated. This is expected
to have an overall positive impact on soil quality, due to the fact that raw wastewater
used to be discharged directly into the environment of the study area without any prior
treatment. In addition, surface and groundwater quality of the region will improve after
the reoperation of the WWTP and controlling the haphazard discharge of raw
wastewater into the Tigris River. In general, the current conditions of Tigris River and
springs in the study area will be improved.
33
Engicon
ESA for Al-Dhebaee WWTP Tirkit District, Salah Al-Din Governorate Environmental and Social Assessment Report
RevNo. 01/09/2019
If any circumstances such as depletion of fuel or electricity shortage cause the
disruption of the treatment plant operation, wastewater in that case will be discharged
directly into the river and the same poor quality conditions of the river will return as
before. However, the wastewater treatment plant is designed to accommodate any
electricity shortages that might occur. In fact, this project and most of infrastructure
projects in Iraq, is provided with emergency power feeder 24/7. In addition, the plant
is equipped with standby generator to cover any power failure from the main national
grid and there is a storage fuel tank which cover fuel supply for 7 days.
Chemical Spills and Leakages
Raw wastewater that is flowing to several units of the treatment plan might leak if the
associated pipes not maintained and monitored regularly. This may result in adverse
impacts on groundwater and soil quality in the area. In addition, leakages from sludge
drying beds could occur and negatively affect the soil as well as water quality.
Furthermore, accidental spills from fuel and oil tanks may occur due to irregular
maintenance and inadequate monitoring. Accidental chemical spills and leakages
could negatively affect soil quality and water quality.
Improper Disposal of Sludge and Solid Waste
The sludge is the final element produced by the treatment plant and may lead to
pollution of water or soil if not properly treated and disposed. The provided sludge
drying bed area is 6,400 m2 for dewatering and drying
It is expected that the sludge holding area will increase the number of insects including
flies and mosquitoes as the sludge may be stored for a certain period before its
disposal. After this period, the dried stable sludge will be sold to farmers to be used as
soil conditioner.
Solid waste generated by the workers and office related activities must be disposed in
licensed disposal sites. If not properly managed or disposed in open areas or burned
onsite, this will lead to the degradation of soil, air and water quality.
Reuse of treated effluent
At present, farmers within the catchment area of the WWTP are using the poor water
quality of the Tigris River for irrigation. After the operation the WWTP, the treated
effluent will improve the water quality of the River and reduce the health risks of
irrigating using water contaminated with raw sewage.

5.2.2 Air Quality
Currently, odor is released in various locations throughout the project area from open
channels (irrigation and drainage canals) discharging directly into the Tigris River. The
project will eliminate these sources of odor. However, foul odor could be emitted from
different processes of the WWTP such as its inlet pump station, screening unit, grit
and oil removal tank, and the mechanical sludge thickening units. These gases include
hydrogen sulfide (H2S) and ammonia (NH3). Knowing that the WWTP is not located
near vulnerable areas (hospitals, schools, residential areas), an odor control system
was not considered in the design. However, the treatment processes release toxic and
flammable gases that can combust if not properly handled. Moreover, these types of
emissions might affect the workers onsite.
In addition, the WWTP could be a source of releasing into the environment greenhouse
gases (GHG) such carbon dioxide (CO2), nitrous oxide (N2O), chlorine gas (Cl2) and
methane (CH4) emanating from combustion emissions from the power plant that will
be constructed on the site. This will add to Iraq’s contribution to global GHG. Moreover,
these gases are flammable, and if fires occur, it could spread to the nearby areas and
negatively affect air quality.
5.2.3 Noise
During the operation, noise is expected to arise mainly from the operation of the
WWTP, pumping stations and from other heavy machinery used during maintenance
activities. The noise generated from these machineries might disturb desert animals.
Moreover, an increase in noise levels is expected to occur from the entering and exiting
of sludge tankers to and from the WWTP. However, this impact is not considered to be
significant as the WWTP is located away from residential areas.
5.2.4 Use of Natural Resources
5.2.4.1 Water Consumption
The WWTP does not require any use of fresh water resources in order to operate.
However, during operation, the workers present on site will use small amount of water
on a daily basis for personal uses. It is worth mentioning that the consumption and
over-exploitation of fresh water for irrigation will decrease as the treated wastewater
may be indirectly used for this purpose
5.2.4.2 Energy Use
As for energy consumption, the proposed project will consume energy from an onsite
power plant for the operation of the WWTP and its different components. As such, the
WWTP will slightly contribute in the depletion of natural resources.
35
Engicon
ESA for Al-Dhebaee WWTP Tirkit District, Salah Al-Din Governorate Environmental and Social Assessment Report
RevNo. 01/09/2019
5.2.5 Land Resources
The project site is located within an area that is already occupied. Thus the proposed
rehabilitation project will not involve a change in the land use of the project area.
5.2.6 Biological Environment
The life of the overall terrestrial and freshwater biodiversity will be improved due to the
reduction of uncontrolled wastewater discharges and the amelioration of their quality
in the area and especially in Tigris River.
The flammable gases generated by the treatment plant such as hydrogen sulfide and
methane may cause fires and negatively affect flora and fauna if not properly managed.
As for the sludge, if it is not properly treated and disposed, biodiversity could also be
negatively affected.
5.2.7 Visual intrusion
The WWTP to be rehabilitated is constructed within a fenced plot and far away from
residential areas. As such, visual intrusion is not expected.
5.2.8 Socioeconomic Environment
5.2.8.1 Economic Activities
Once constructed, permanent job opportunities will be created for the local population
at the facility. The operation of the WWTP requires the employment of skilled
technicians, professionals and guards.
5.2.8.2 Traffic
Once the WWTP starts to operate, a slight increase in the number of cars passing on
the roads (local and agricultural) that leads to the treatment plant will be expected
mostly those transporting the facility workers and engineers. Moreover, the trucks that
are responsible to transfer the generated dried sludge to farmers will frequently use
these roads.
5.2.9 Public Health and Safety
The proper treatment of the sewage discharges and its safe disposal into the
environment will reduce surface water pollution. As a consequence, the risk of
proliferation of disease vectors and incidence of infections directly or indirectly will be
reduced. As a result, elimination of raw sewage discharge will improve the overall
36
Engicon
ESA for Al-Dhebaee WWTP Tirkit District, Salah Al-Din Governorate Environmental and Social Assessment Report
RevNo. 01/09/2019
health of the population that is using the Tigris River for several purposes, as well as
their quality of life.
However, workers at the treatment plant will be exposed to occupational risks from
mishandling of machinery, falling, slipping and electrocution. A collection of gases
commonly released by the WWTPs can cause health related problems for workers
inside the facility. The gases include hydrogen sulfide, carbon dioxide, methane and
ammonia. Exposure to high concentrations of carbon dioxide and ammonia could
cause respiratory diseases to the workers. Many health problems such as eye irritation,
headaches, cough, sore throat, nausea and shortness of breath could be caused by
exposures to hydrogen sulfide. In addition, ammonia could lead to lung damage if the
individual has been exposed for a long period of time.
The exposure of the workers to untreated wastewater and sludge could also be a
cause of health problems. Workers could be exposed to pathogens, gases, heavy
metals, microorganisms and chemicals through ingestion, inhalation, or contact with
skin. If it accumulates on site, sludge will lead to odors, vector breeding and infections.
As part of the sewage treatment process, chemicals and chlorine gas will be stored
onsite. Chlorine is a highly toxic and, if used in high concentrations, can cause skin
burns, severe irritation, tissue destruction and eye damage. It is 2.5 times heavier than
air, thus any leak will stay close to the ground where it can be inhaled by an operator
(Pa. DEP, 2016). As such, if not stored properly, exposure to these chemicals may be
a health risk to the operators of the treatment plant.
GBV and VAC may occur during the operation of the wastewater treatment plant.
Incidents related to GBV and VAC include criminal behavior, sexual harassment of
women and girls, exploitative sexual relations, and illicit sexual relations with minors
and child labor from the local community.
5.2.10 Cultural Heritage
There is no evidence of any historical sites in the proposed location of the wastewater
treatment plant. Thus the proposed project will not impact the cultural heritage of the
region.
The following Tables (Table 5-3 and Table 5-4) present a summary of the anticipated
impacts that might arise during the construction and operation phase along with an
impact evaluation based on the criteria discussed at the beginning of the section.

6.1 SITE ALTERNATIVE
6.2 PROCESS ALTERNATIVE
6.3 REUSE OF THE TREATED WASTEWATER
The current project aims to rehabilitate an already existing WWTP in order to bring it
back to work. Moreover, the WWTP is located at the southwest of the Tikrit city in a
rural area far away from any residential or sensitive area. Therefore, building a new
treatment plant in another location is not considered a sustainable and feasible option
compared to the rehabilitation and operation of the existing one.
In wastewater treatment plants, the installation of odor control systems helps in
reducing the foul odor that is emitted from several units during the process of
wastewater treatment. This odor a collection of gases such as hydrogen sulfide, carbon
dioxide, methane and ammonia that affect nearby residents and the workers onsite.
Physicochemical methods can be implemented in order to treatment the odor within
the facility. The treatment is done by the passage of odorous air upwards through a
vertical cylindrical tank and subjecting it to a sprinkling jet of oxidizing chemicals such
as acids or chlorine solutions. As such, the odour forming impurities will consequently
be oxidized and washed down to the bottom of the tank.
As for the odorous air that is collected from the emanating structures such as
wastewater pump stations and inlet structures, grit and oil removal chambers and the
mechanical thickening units can be forced by special fans through a plastic media
housed in vertical vessels where the above explained reactions also take place to
remove odor generating substances in the fed air. To facilitate these reactions, the
oxidizing chemicals must be periodically sprinkled on the plastic media (to provide a
large surface area) in the cylindrical tank and the dirty air passing through this media
will have an increased contact surface with the chemicals. The system includes
necessary pumps, instrumentation and process control panel.
However, this option is not considered to be feasible since the WWTP is located away
from residential areas and sensitive receptors. Installing an odor control system to
reduce an insignificant impact (based on site location analysis) will only increase the
rehabilitation cost as well as operation and maintenance cost with little value added.
With growing demand on water due to population increase and the improvement of
their standard of living, the gap between demand and supply increases. The increase
in water demand far exceed the rate of finding additional supplies. Reuse of treated
wastewater reduces the demand and reliability on fresh water resources and

RevNo. 01/09/2019
6.4 NO ACTION ALTERNATIVE
represents a constant ever-increasing source for irrigation. Since Iraq is classified
among the countries of limited water resources and in the water shortage zone, the
importance of reusing the treated effluent from WWTP becomes more significant.
However, this option was not considered because of its relatively high cost for frequent
monitoring of water, soil, and public health, awareness and training to ensure proper
use of the treated effluent.
In the No-Action Alternative, the project is not implemented and the status of quo
persists. As the wastewater treatment system is not functioning currently in Tikrit, direct
discharges of uncontrolled wastewater to the Tigris River and open lands will remain
and increase over time. As a consequence, pollution of surface water will continue to
worsen. Moreover, if nothing is done about the situation, the currently used cesspits
will most likely clog with time and house owners will have to empty those more
frequently thus imposing a financial burden on the population. New houses which will
be built in Tikrit and need to provide cesspits for their wastewater collection thus adding
to the cost of construction.
Knowing that, there is an urgent need for the rehabilitation and reoperation of Al-
Dhebaee WWTP in order to reduce the pollution load that is negatively affecting
residents’ health and causing environmental stresses including deterioration of fresh
water quality, increase in river contamination, and disturbance of fauna and flora
species. Therefore, this alternative is not considered economically, socially and
environmentally feasible.

7.1 MITIGATION MEASURES DURING CONSTRUCTION
This section outlines the measures required in order to mitigate all impacts identified
in Section 5 as well as ensure proper monitoring. These measures have been included
in an Environmental Management Plan (EMP)
7.1.1 Soils and Water Quality
The contractor should present and abide by a spill prevention and management plan
that includes the following:
Proper handling of chemical and oil on a paved or sealed floor;
Used oil or chemical must be stored in an appropriate area until it is collected and disposed in licensed sites;
A spill response plan including a spill clean-up procedure should be present at the construction site and all workers should be trained in order to implement it in case of accidental spillage;
The reduction in use of chemicals and the regular maintenance of the used vehicles and machines;
A spill collection tank must be installed under generators and specific equipment.
The contractor should ensure during the construction and rehabilitation activities that
the volume of accumulated sludge and debris, destroyed units, exploded concrete
objects will be disposed properly. The contractor must ensure that this type of waste
should not be disposed in the Tigris River or in open areas under any circumstances.
7.1.2 Air Quality
In order to reduce the project’s impact on air quality, the following mitigation measures
must be implemented:
Vehicles, equipment and machinery used during construction and rehabilitation should be regularly maintained;
Catalytic converters should be installed into vehicles and generators. A catalytic converter converts around 90% of hydrocarbons, carbon monoxide and nitrogen oxides from the engine into less harmful carbon dioxide, nitrogen and water vapor (Taylor, 1984);
Open burning of solid waste must be prohibited;
Loading of raw material including debris should be done in closed areas;
Raw material storage areas should be covered;
As part of a Dust Management Plan, water should be sprinkled in order to suppress dust. During windy weathers, dust generating activities should be stopped;
Onsite surfaces should be paved (the destroyed road parts) in an effort to reduce dust emissions;
7. ENVIRONMENTAL MANAGEMENT PLAN
42
Engicon
ESA for Al-Dhebaee WWTP Tirkit District, Salah Al-Din Governorate Environmental and Social Assessment Report
RevNo. 01/09/2019
Vehicle speed must be limited on unpaved areas especially within the city perimeter;
Transported material should be covered.
As for odors, frequent inspection and monitoring of wastewater pipes and chemical storage tanks must be done to detect any leakages. In addition, proper ventilation system must be installed in chemical storage areas and in all confined areas.
7.1.3 Noise
In order to reduce and control the noise generated during the construction and
rehabilitation phase, the following mitigation measures must be implemented:
Use muffled and small equipment and machinery whenever possible;
Place noisy equipment and generators as far as possible from working areas;
Equip the generators with noise insulator;
Use temporary noise insulators and barriers (plywood barriers) around excavation areas;
Regular maintenance of all noisy equipment and machinery. This includes changing lubricants, replacing damaged parts, and installing mufflers;
Drilling and excavation activities should be executed only during working hours;
Use hearing protective equipment such as earmuffs during noisy activities such as drilling (OSHA, 2011)
7.1.4 Use of Natural Resources
Several mitigation measures can be implemented in an effort to reduce natural
resource depletion and consumption. These measures include:
Reduce water wastage whenever possible;
Harvest rain water and use it as an alternative to fresh water;
Whenever possible, use dry-cleaning instead wet cleaning;
Machinery should be turned off and not left idle for long periods;
Training and awareness should be raised to workers concerning water usage best practices and water conservation;
The light in the site offices must be shut down during the night;
Site offices and the construction must be equipped with awareness sheets on how to use energy in an efficient way;
Machinery and equipment must be turned off when not in use.
7.1.5 Land Resources
The rehabilitation phase will not change the land use of the area since the WWTP is
already constructed. Thus no mitigation measures will be proposed. However, it is
43
Engicon
ESA for Al-Dhebaee WWTP Tirkit District, Salah Al-Din Governorate Environmental and Social Assessment Report
RevNo. 01/09/2019
recommended to preserve natural habitats whenever possible within the WWTP
location.
7.1.6 Biological Environment
In order to reduce the impact on the biological environment including natural habitats,
flora and fauna, the contractor should abide by the measures mentioned above for
noise, air, water and soil pollution prevention measures.
7.1.7 Visual Intrusion
The impact on visual intrusion is considered to be insignificant since the WWTP is
already fenced with a concrete wall. Hence no mitigation measures are required.
7.1.8 Socioeconomic
7.1.8.1 Economic Activities
The construction and rehabilitation of the proposed project is considered to have a
positive impact on the economical profile of the local community. In order to enhance
this impact, priority of hiring should be giving to qualified local residents. However, it is
important to abide by the Labor Law and ensure that workers below 18 years are
prohibited to undertake hazardous work during rehabilitation works such as:
Working with dangerous machines, equipment, or tools requiring a manual intervention or lifting of heavy loads;
exposure to unusual temperatures, noise or to movements harmful to their health;
Working in difficult conditions for long hours or in some conditions during night.
7.1.8.2 Traffic
The contractor should ensure that all the construction activities of the WWTP are not
blocking traffic on the roads of the towns. In addition to proper warning signs, a worker
should be positioned on the road near an active construction area to warn the passing
cars and ensure the traffic is not blocked. The contractor should also ensure that the
transported material and debris by the trucks are well covered.
7.1.9 Public Health and Safety
The contractor should develop and abide by a health and safety plan that covers the
following issues.
44
Engicon
ESA for Al-Dhebaee WWTP Tirkit District, Salah Al-Din Governorate Environmental and Social Assessment Report
RevNo. 01/09/2019
7.1.9.1 Personal Protective Equipment
The contractor should safeguard worker safety from any possible accident or injury.
Workers should wear personal protective equipment (PPE) and the contractor should
supplement the working site by a first aid kit. The contractor should therefore ensure
the following:
Workers should wear hard hats to avoid any potential objects fall or accidental head contact with electrical hazards;
Safety glasses should be worn during the construction phase in order to avoid the exposure to flying particles or harmful chemicals whenever needed;
Workers should wear the right gloves to protect their hands. Different type of gloves could be used according to the undertaken construction activity;
Boots with slip-resistant and puncture-resistant soles should be worn by the workers on construction site. This is essential to protect their feet.
7.1.9.2 Electrical Safety
The electrical activities and working on new and existing hot electrical circuits should be prohibited if power is still turned on;
All frayed, damaged or worn electrical cords or cables should be replaced and flexible cords and cables should be protected from damage;
All electrical tools and equipment should be maintained and checked regularly for any defect;
7.1.9.3 Public and Worker Safety
Local residents’ safety and passers-by should be ensured especially within the city.
Warning signs of construction and rehabilitation should be placed at the external part
of the site and at a distance of 100 meters.
Moreover, before the initiation of the construction activities, the contractor should
prepare an Occupation Health and Safety (OHS) plan in compliance with the World
Bank EHS guidelines with focus on Section 4 (Construction and Decommissioning).
The contractor should also provide qualified personnel in an effort to supervise and
ensure that the workers are abiding by the plan.
Furthermore, in order to reduce the risk of GBV and VAC as much as possible, the
contractor should implement the following prior to project rehabilitation:
Draft Codes of Conduct and the guidelines for a GBV and VAC Action Plan;
All workers including contractor, foreign workers and international consultants should sign codes of conduct;
All workers are committed to prevent and report GBV and VAC within the work site and in its immediate surrounding communities;
Respond to GBV and VAC events as a matter of priority.

7.2 MITIGATION MEASURES DURING OPERATION
7.1.9.4 Cultural Heritage
The proposed project is located within an area that does not include cultural heritage
and archaeological site. Hence, no mitigation measures are required.
7.2.1 Water and Soil Quality
Wastewater Treated by the Plant
Although the treatment plant will enhance the overall water and soil quality in the
region, frequent monitoring of the generated treated wastewater effluent must be done
to ensure the proper functioning of the treatment process. This include regular
microbiological and physiochemical testing. Moreover, a power shortage or operational
failure emergency plan must be set and regularly maintained in order to avoid the
discharge of untreated wastewater directly into the river.
Wastewater Leakages and Chemical Spills
The following mitigation measures must be implemented in order to prevent the
adverse effects of the proposed WWTP on the soil and water quality:
Ensure regular maintenance of WWTP units to detect any leakages;
Install impermeable lining at the base of the drying beds in order to avoid any seepage to the soil layers underneath;
Regular maintenance of the drainage collection system under the sludge drying beds regularly;
Chemical and fuel storage tanks (chlorine, diesel oil, etc.) must be monitored frequently in order to avoid leakages and spills
Chemical and fuel storage tanks must be placed on a paved ground and a collection tank must be installed underneath it. These tanks should be regularly maintained.
Improper Disposal of Sludge and Solid waste
The following mitigation measures must be implemented in order to avoid the
degradation of soil and water quality in the region of the WWTP:
Prohibit the transportation of sludge before the drying process ends;
Prohibit the disposal of dried sludge in open areas;

Staff should take into consideration the following recommendations in order to properly
manage sludge drying beds:
The staff must ensure that the sludge is transported to an adequate depth of the drying bed and it should not be filled to the brim.
The flow of the media should be continuously inspected. The staff should check if it is filtering clear liquid that could be observed from the underdrainage system. If liquid is not clear or if no drainage is observed the staff should inform the water establishment.
Once dried, sludge should be removed carefully in order not to disturb the top sand layer on the drying bed.
Proper handling and transportation must be ensured. This includes:
- Safety training program for workers, safe handling and personal hygiene practices to reduce exposure to pathogens and vectors
- Regular sludge management training sessions must be conducted; - Use vacuum trucks or tugs for removal of sludge instead of manual
methods; - Vehicles transporting the sludge must be covered; - Provide and require use of suitable personal protective clothing and
equipment such as rubber gloves, aprons, and boots to prevent contact with sludge
- Provide shower and change clothes areas for workers before leaving work and provide laundry service for work clothes.
- Long onsite storage periods must be prohibited;
- Workers must take the adequate vaccines on a regular basis.
Dried sludge must be monitored for its infectious and hazardous parameters before disposal.
Disposal of dried sludge in open dumps must be prohibited under any condition
The site of sludge disposal must be selected based on scientific and social agreement between municipalities and MOE
59
Engicon

Sludge disposal site must be equipped with geo-membrane lining if groundwater is present and a leachate collection system.
Finally, sludge could be disposed safely.
7.4.6 Emergency Response Plan
The WWTP operator should develop and implement an Emergency Response Plan to
ensure that the treatment plant management meets the requirement in developing,
maintaining, and reporting emergency preparedness and resource activities to provide
protection to human health, public welfare and the environment. The plan should be
available in case of emergency as part of the monitoring plan. The purpose of the plan
is to:
Ensure the effective management of emergency efforts involved in preparing for and responding to situations associated with emergencies;
Prevent or minimize toxic air emissions released to the environment;
Reduce the probability of human injury;
Prevent or minimize exposure to the operator or other support or maintenance personnel;
Assist response personnel in determining and performing proper remedial actions quickly and limit potential loss or damage;
Reduce the magnitude of environmental and other impacts.
This plan would mainly be focused on setting various emergency scenarios along with
a specific response plan for each situation. It should be comprehensive, clear and
concise. The roles and responsibilities of the staff should be clearly defined, areas of
risk and hazard should be predetermined, and procedures for dealing with a release
should be clearly outlined. An emergency plan for the wastewater treatment will include
the following elements:
A description of the overall strategy of the plan (before, during, and after an emergency) and provide background information to the employees.
How to report fires and other emergencies, emergency evacuation procedures and route assignments, procedures to be followed by the staff who remain to conduct some critical functions before they evacuate, and procedures to account for personal after emergency evacuation;
A comprehensive list of site activities and associated risks to assist in assessing the expected type, frequency, and size of product releases that could occur;
A response organization chart that identifies the on-site coordinator and emergency response personnel and clearly indicates their roles and responsibilities;
Names and phone numbers of persons who can be contacted for further information on the emergency plan;

and acceptance by staff and will be reviewed periodically and updated when
necessary. The implementation of the training programs will raise awareness to Tikrit
WWTP operators in the following topics:
Environmental laws, regulations, and standards;
Wastewater management Plan;
Occupational hazard and personal protective equipment;
Emergency response and chemical spills;
Sampling techniques and environmental monitoring guidelines;
Risks associated with handling of untreated sludge;
Risks associated with floods in case of river flood;
Pollution health impacts and prevention measures;
Instructions on the use of protective clothing while handling sludge;
Operating procedures at the facility (Incident Reporting and Investigation);
Fire safety.

The purpose of a grievance mechanism is to ensure that all feedback and complaints
received from stakeholders, customers, employees, contractor staff and the public in
general are documented, considered and addressed in an acceptable and timely
manner.
A formal grievance mechanism allows for complaints to be made in person, in writing,
by telephone or online (Annex 2). This mechanism should be adopted during both the
rehabilitation and operation phases. The person responsible for receiving and following
up on grievances is the Health, Environment and Safety Officer. Complaints received
should be summarized and listed in a log book, containing the name/group of
commenter/complainant, date the comment was received, brief description of issues,
information on proposed corrective actions to be implemented (if appropriate) and the
date of response sent to the commenter/complainant. A summary of the grievance log
should be presented to the General Authority for Sewerage and Water annually.
In case of a complaint, the HSE officer will confirm receipt of the grievance within 5
days, decide whether it is a valid complaint is considered relevant. The
contractor/operator should commit to respond within 15 days of receipt of grievance.
The grievance procedure should be posted on the WWTP premises, visible to the
public at all time. Confidentiality is guaranteed to all individuals upon their request. The
contact information for making grievances should be that of the Health, Environment
and Safety Officer.
Figure 7-1 presents a detailed flowchart describing the process of grievance starting
form reception of grievance to implementation of corrective measures.

A public consultation session was held at the Salah El-Denn Sewerage Directorate on
June 17, 2019. The session was attended by 30 participants who included engineers,
teachers and local residents The purpose of the hearing was to inform the residents
and stakeholders about the proposed rehabilitation of the WWTP and its different
components and to document their concerns and feedback.
During the public consultation, a brief description of the WWTP and its components
was presented to the attendees along with the potential environmental issues related
to the proposed project. Moreover, an environmental impact matrix was distributed to
the participants to be filled out. It included environmental, social, health and safety
issues that may be relevant to the proposed project during construction and operation.
The results of the questionnaire showed positive feedback from the local community
regarding the rehabilitation and reoperation of the WWTP. The response on most of
the questions was that the project will positively impact water quality in the region and
that the overall health of the community will be enhanced as a result of treating the
wastewater before discharge. The attendees also agreed that the proposed
rehabilitation project will encourage more development projects in the area and will
offer job opportunities to the local community during both the construction and
operation phases. Some pictures that were taken during the public participation are
presented below (Error! Reference source not found.). As for the list of attendees a
nd the filled questionnaires, they are attached in the Annex of the report.

The study shows that most of the impacts of the project during rehabilitation and
construction are temporary and can be minimized with proper mitigation. However,
during the rehabilitation phase, the impacts that are of major concerns are those
related to the health and safety of the works. Moreover, another major issue that is
associated with such rehabilitation projects is the removal and disposal of debris and
destroyed units. However, adequate mitigation measures were stated in order to safely
dispose these material.
Another major issue of concern is that of proper operation and maintenance of the
treatment plant to ensure an adequate level of treatment of the wastewater before
discharge into the river, as well as sludge before applying them onto agricultural areas.
This will require a commitment to regular monitoring and inspection of different
wastewater process. Moreover, continuous training programs must be conducted
during the operation of the plant and all WWTP units must be regularly maintained.
If all these conditions are met, it is likely that the overall environmental and social
impact of this treatment plant will be positive.
It is worth mentioning that this project will end the uncontrolled discharge of wastewater
into Tigris River without any prior treatment. Hence the operation of the WWTP will
contribute in reducing sources of pollution that are degrading surface water quality,
thus limiting its final usage (irrigation, industrial …).
