MADURAI CORPORATION

INTRODUCTION

Madurai known as the “Temple City” is one of the oldest cities in India. This city is situated

about 500 Km South West of Chennai, spread over an area of 51.96 Sq. Km. It is the second

largest city in Tamil Nadu, having a population of 1.15 million. This city is famous for Arulmigu

Meenakshi Amman Temple. The City Municipal Corporation was formed in 1971.

JAWAHARLAL NEHRU NATIONAL URBAN RENEWAL MISSION

The Government of India launched the Jawaharlal Nehru National Urban Renewal Mission

(JnNURM) on 03.12.2005.The objectives of the Mission is to fast track the development of

cities and to ensure integrated development of urban infrastructure and services, secure effective

linkage between asset creation and management and to ensure adequate investment of funds to

address the deficiencies in the urban infrastructure.

The Madurai city is one among the 63 Mission cities under the JnNURM. According to the

population the Mission cities are categorized into Mega cities, Million plus cities and Heritage

cities. The Madurai city comes under the category of heritage city. The Ministry of Urban

Development, Government of India, has approved the “City Development Plan” prepared by the

Madurai Corporation on 26.06.2006. The Memorandum of Agreement was signed by the

Government of India, the Government of Tamil Nadu and the Madurai Corporation on

29.07.2006.

The Central Sanctioning & Monitoring Committee of the Ministry of Urban Development and

the Ministry of Housing and Poverty Alleviation, Government of India have approved five

projects under the Urban Infrastructure & Governance and three projects under the Basic

Services to the Urban Poor respectively. The details are as follows:

1. SECOND VAIGAI WATER SUPPLY SCHEME

The drinking water requirement of Madurai city is 155 MLD (as per norms 135 litres per capita

per day prescribed by the Central Public Health and Environment Engineering Organization

(CPHEEO)). The city is currently getting 83 MLD of water from the First Vaigai Water Supply

Scheme and the existing head works located in and around the Madurai City.

VAIGAI DAM

The First Vaigai Water Supply Scheme was commissioned in 1996 with the Vaigai Dam as

source and under this scheme 900 MCF of water is drawn annually. Presently 68 MLD of water is

being distributed through the existing distribution system, while the balance 600 MCF of water is

released through the river Vaigai of which 15 MLD of water is being drawn from the existing

head works (Infiltration galleries) located at Melakkal, Kochadai and Manaloor.

The above mentioned 600MCF of water has been considerably reduced over the years due to

seepage and evaporation. Therefore to meet the demand for the increasing population and

corresponding water demand, a proposal was formulated to draw this quantity through pipeline to

minimize the water loss.

Page 6: Brochures Published Madurai

 

 

The City Development Plan prepared for the Madurai Corporation highlighted the inadequacy of

the water supply and hence a comprehensive water supply scheme was proposed under the

JnNURM. Based on the proposal of the Corporation, the State Level Steering Committee

recommended the project and the Central Sanctioning and Monitoring Committee of the Ministry

of Urban Development, Government of India, sanctioned the project at a cost of Rs.59.316 crore

under the Urban Infrastructure and Governance component of the Jawaharlal Nehru National

Urban Renewal Mission in May 2006.

This project comprises of drawl of 600 MCF of water (out of total allocation of 1500 MCF

allotted for Madurai Corporation) through the intake well located at 1500m from the Vaigai Dam,

laying of 16.60 km of Raw Water Main from intake well to the water treatment plant,

construction of Aerator, Stilling basin, Raw Water - Channel and Flash Mixture, clarifier and

filter bed, clear water transmission main from the water treatment plant to the Madurai City, and

construction of five over head water tanks. The work order was issued on 12.02.2007 and the

project was completed on 31.03.2009.

Page 7: Brochures Published Madurai

 

 

SCOPE OF THE PROJECT :

• The Government has allotted 1500 MCF of water per year for Madurai Corporation of

which 900 MCF of water per year is being released through pipe line (through the First

Vaigai Water Supply Scheme) and 68 MLD of water is being supplied through the

existing system. Currently 60 lpcd of water is supplied to the public through the existing

distribution system.

• Out of 1500 MCF of water sanctioned for Madurai Corporation, the remaining

600 MCF of water per year is being released through the River Vaigai of which only 15

MLD of water is drawn from the existing three head works (Infiltration galleries) located

at Melakkal, Kochadai and Manaloor. Utilization of this quantity has considerably been

reduced over the years due to seepage and evaporation loss.

• Therefore to meet the growing water need of the increasing population a proposal was

formulated to draw 600 MCF of water per year through pipeline (to draw an additional

47 MLD of water). Consequently, with the commissioning of the project, the water

supply to the city will increase to 115 MLD and the per capita water supply is expected to

increase from 60 lpcd to 100 lpcd.

SALIENT FEATURES:

• 4.00 meter diameter intake well and 4.50 meter diameter collection wells have been constructed in the river bed.

• Laying of 16.60 km of raw water pipe

• The existing water treatment plant has been upgraded from 71.6 MLD to 118.6 MLD by introducing tube settler in clarifiers and dual media in the filter bed.

• Laying of 65.00 km length of treated water pipe

• Construction of five reservoirs having a total capacity of 31 lakhs litres.

• The project has two innovative technologies :

o A tube settler in the clarifier which will increase the capacity of the clarifier by 100 %.

o A dual media filtering system in the filter bed which will increase the capacity of filtration by 100%.

• The treated water from the water treatment plant at Pannaipatty reaches the city by gravity resulting in considerable savings in the operation and maintenance.

3. SOLID WASTE MANAGEMENT

Presently 400 tonnes of solid waste is generated per day in the Madurai Corporation area. All

these wastes are collected by sanitary workers through pushcarts, tri cycles, autos and bins of

various sizes. The collected wastes are transported to the dump yard through the tipper lorries

and tractors. The dumping of waste in open causes pollution around the existing dump yard. The

capacity of the vehicle used for the secondary collection was not sufficient. Hence this project

was proposed to create sufficient infrastructure for primary & secondary collection and facilities

for processing of waste in compliance with the Municipal Solid Waste (Handling and

Management) Rules, 2000.

Under this project, it is proposed to ensure the segregation of waste at source by providing house

hold bins and daily clearance of waste by procuring sufficient bins and vehicles. The

establishment of 350 TPD waste processing unit is underway. The construction of sanitary

landfills for the accumulated waste and the present and the future non- recyclable waste has been

completed. The organic waste will be converted into bio manure and the recycled waste will be

sent for reuse.

The Ministry of Urban Development, Government of India has sanctioned the Solid Waste

Management Project on 02.02.2007 at a cost of Rs. 74.29 crore. The Government of Tamil Nadu

has accorded the Administrative Sanction for this project on 17.04.2007. This project has been

divided into VII packages.

SCOPE OF THE PROJECT: In this project, it has been proposed to procure materials and

machineries to implement the segregation at source, door to door collection and treatment &

disposal of the waste in compliance with the rules. Sanitary landfills for the accumulated waste

and the residual waste and the construction of the waste processing unit have been proposed

under the Public Private Partnership (PPP) Mode. The Waste processing unit has been designed

for 350 tonnes per day capacity.

SALIENT FEATURES

4. STORM WATER DRAINAGE

The Storm Water drainage system in Madurai Corporation area is inadequate and does not

effectively drain the flood water during heavy rains resulting in the stagnation of rain water in

many low laying areas of the city. The flooding of rain water causes unhygienic condition. The

stagnation of water during rains also causes damage to the bitumen roads, besides causing

hindrance to the transportation which affects the normal life. To eliminate these problems it is

proposed to provide an integrated drainage system covering all the areas in the 72 wards of the

Madurai Corporation.

The Ministry of Urban Development, Government of India has sanctioned the Storm Water

Drainage Project on 20.04.2007 at a cost of Rs. 256.87 crore. The Government of Tamil Nadu

has given the Administrative Sanction for this project on 02.05.2007.

SCOPE OF THE PROJECT: The road side drains are proposed to be constructed covering

every street ultimately linking all the drains to the major channels. All the major channels are

also proposed to be linked to receive the flood water from primary, secondary and tertiary drains

constructed along the roadside. Thus the entire rain water collected will be disposed efficiently

through the integrated system of roadside drains and the major drains.

SALIENT FEATURES

• The narrow streets will be constructed with one side drain.

• The wider roads will be provided with the side drains

• The cover slabs will be provided over the drains

• The major channels will be constructed with retaining walls on both the sides.

• The floor of the channels will also be lined with cement concrete and the rain water harvesting arrangements will be provided at 50m intervals.

• The culverts and the bridges will be constructed or re-constructed wherever necessary.

OUTCOME OF THE PROJECT

• The existing defunct irrigation channels are proposed to be used as major drains during

flood.

• The rain water collected from the roadside drains will ultimately drain thorough these

major channels.

• The flooding of rain water in the city area and the stagnation of rain water and sullage in

the channel will be prevented, there by reducing the mosquito menace.

• Most of the city roads are not having roadside drains, and the stagnation of rain water

over the bituminous surface causes heavy damage to the urban roads. These will be

minimized after the construction of roadside drains.

5. UNDER GROUND SEWERAGE SCHEME

The sewerage system was first established by the British in Madurai to cover the core city area

(30% of the present city area) of the town between 1924 and 1959. It was further expanded in

1983. Subsequently, the National River Conservation Project (NRCP) was implemented in

Madurai to give 100% underground sewage. The extension and the newly developed areas are

not covered by the underground sewage system. The old underground sewers are insufficient.

Due to the inadequacy of pumping stations, the raw sewage is being pumped into the channels

which ultimately reaches the River Vaigai. Un-covered areas within the Corporation limits suffer

the potential risk of open discharge of sewage.

The Ministry of Urban Development, Government of India has sanctioned the Under Ground

Sewerage Scheme to Madurai Corporation on 20.07.2007 for implementation at a cost of Rs.

229.34 crore. The Government of Tamil Nadu has issued Administrative Sanction for this

project on 24.10.2007.

SCOPE OF THE PROJECT

In this project, it is envisaged to cover the uncovered areas of 72 km, renovation of the existing

pumping stations and the pressure pipes, construction of two sewage treatment plants at

Avaniapuram (125 MLD) and Sakkimangalam (45.7 MLD) on DBOT basis to bring down the

Biological Oxygen Demand (BOD) level to 10 mg per litre.

SALIENT FEATURES

• Development of sewage system in uncovered areas.

• Renovation of existing sewage system.

• Renovation of old main pumping station and sub pumping station.

• Construction of two new sewage treatment plants.

PROJECT IMPLEMENTATION: This project was taken up for implementation in 3
