CHENNAI METROPOLITAN WATER SUPPLY AND SEWERAGE BOARD

 DRAFT POLICY NOTE 2007-08

        To provide safe drinking water to citizens and collection, treatment and safe disposal of the waste water is the primary responsibility of any Government.  In this direction, the Government of Tamil Nadu is taking all measures to improve the drinking water availability as well as to collect, treat and safely dispose the waste water in Chennai city and its adjacent Urban Areas.

        The Government of Tamil Nadu will continue to take all efforts to get 12 TMC of water from Krishna Water Supply Scheme and speed up the installation of Sea Water Desalination Plants to ensure water security to the people of Chennai.

WATER & WASTE WATER MANAGEMENT:

        The Chennai Metropolitan Water Supply and Sewerage Board (CMWSS Board) was constituted as a statutory body in August 1978 for exclusively attending to the growing need of, and for planned development and appropriate regulation of water supply and sewerage services in the Chennai Metropolitan Area with particular reference to the protection of Public Health and for all matters connected thereto. 

         The CMWSS Board is vested with the responsibility of planning, construction, operation and maintenance of water supply and sewerage system in Chennai Metropolitan Area (CMA).  Though its operation is limited to Chennai Municipal Corporation Area in general, the Board is also extending its services to the surrounding urban local bodies (with about 7.88 sq.km. in extension areas and Manali New Town) and has already initiated measures to provide services for the entire Metropolitan Area. 

         The A Master Plan for the management of water supply and sewerage for the City, which was prepared in the year 1978, was revised in the year 1991 and updated in 1997.  Improvement and expansion works are being carried out as per the Master Plan proposals.   The implementation of Master Plan proposals has been taken up in stages.  The following is the growth profile of the Board since its formation.

STATUS OF WATER SUPPLY:

            Surface water sources such as reservoirs at Poondi, Cholavaram, Redhills, Chembarambakkam, Veeranam Lake, Rettai Eri, Porur Lake and Kandaleru Reservoir in Andhra Pradesh under Krishna Water Supply Scheme are the main sources of water supply for Chennai City and the Adjacent Urban Areas.

            Ground water from the Wellfields developed in the Araniyar - Kortaliar River Basin and Southern Coastal Acquifer and Brakish Water based Reverse Osmoasis Plants are other sources of water supply.

            During 2006-2007, water was received from Kandaleru reservoir in Andhra Pradesh under Krishna Water Supply Scheme  in two spells i.e. 2.869 TMC from 19.08.2006 to 06.11.2006 and 2.315 TMC from 14.12.2006 to 08.02.2007 and the total quantity received is 5.184 TMC.  This helped in maintaining the City Water Supply continuously at the rate of about 645 MLD even though the inflow in the rReservoirs due to the North-Eeast monsoon was not appreciable.   Further, for the first time, water received under Krishna Water Supply Scheme was conveyed to Chembarambakkam lake during January 2007. 

Daily water supply is maintained in the Chennai city and will be continued. Everyday 575 million litres of water is supplied    to the domestic consumers and another 65 to 70 million litres   to the industries and bulk consumers.  Out of 15,460 streets in the operational area of the CMWSS Board, water is supplied through pipeline in 15,155 streets.  There are nearly 130 streets where water does not reach through pipeline due to inadequate pressure inspite of availability of pipeline infrastructure.  To ensure piped water supply to these streets, distribution system improvement works will be taken up during current year and completed in next two years. This will help in equitable distribution of water.

In July 2006, there were 336 streets without water distribution mains, out of which  water mains have been  laid in 161 streets.   In the remaining 175 streets, the work is under progress and will be completed by June 2007.

Streets where water could not be supplied through pipe line network, including the streets without water supply mains, are served through tankers.  For this purpose, on an average 1300 tanker trips are made daily.  Further, for needy consumers, about 700 tanker trips are made daily on payment basis.

India Mark-II Pumps, numbering 6924, are maintained in the city to meet the water needs of residents, other than for drinking and cooking purposes.

With the available storage in the reservoirs and expected receipt of water from Krishna Water Supply Scheme,  the city water supply will be maintained daily at the current rate of supply till the onset of North East monsoon.

SEWERAGE SYSTEM:

            Collection, treatment and safe disposal of the waste water in Chennai city is one of the primary duties of CMWSS Board.  99% of the city is covered by the Under Ground Sewerage Network.  Apart from the five Zonal systems other small systems developed by the Tamil Nadu Housing Board in their neighbourhood scheme areas are also functioning and are connected to the nearest sewer mains. 

            CMWSS Board   maintains about 2663 km. length of sewer mains, 180 Pumping   Stations and Sewage Treatment Plants at 5 locations with a combined capacity of 486 MLD. In July 2006, there were 177 streets without sewer mains, out of which sewers have been laid in 70 streets.  In the remaining 107 streets, sewer laying  will be completed in the current year.

   CHEMBARAMBAKKAM WATER TREATMENT PLANT :

                      In order to treat the expected receipt of water under Krishna Water Supply Scheme, during August 1996 the Government accorded administrative sanction for the construction of a Water Treatment Plant with 530 MLD capacity at Chembarambakkam with an estimated cost of Rs.296.00 crore. The construction work is nearing completion and the laying of transmission main for conveying the treated water from the Treatment Plant to Chennai city is also in progress. It was programmed to commission the plant to supply 200 mld of water in the first Phase during September 2006.  Due to court cases on land acquisition on the alignment of the pipe line, the work was delayed. Further, due to water stagnation on the work site,  due to rains, work could not be speeded up.  The work is now completed and pre-commissioning activities of the water treatment plant have commenced.  The entire work will be completed by June 2007.

SEA WATER DESALINATION PLANT - I ( Kattupalli / Minjur)

As the present water supply sources of Chennai City are dependent on the monsoon rainfall and any failure of the monsoon adversely affects the city water supply, the CMWSS Board had proposed to set up a desalination plant on DBOOT (Design, Build, Own, Operate and Transfer) basis as a drought proofing measure.  Accordingly, a Bulk Water Purchase Agreement was executed with the company M/s. CWDL(Chennai Water  Desalination Ltd.)

 The Government in the cabinet meeting held on 16.10.2006 decided to implement the 100 mld Desalination Plant on DBOOT basis at Kattupalli near Minjur. The company obtained all clearances and achieved the Financial Close on 25.01.07. The foundation stone was laid on 25.02.2007 and preparatory  works have been commenced by the company.  The first phase of the Plant with 15 mld supply will be commissioned in June 2008.  The full capacity of the plant for 100 mld supply will be commissioned in 3 months thereafter.

 SEA WATER DESALINATION PLANT - II (at Nemmeli)

To reduce the gap between the demand and supply of water in the Chennai Metropolitan Area and to augment the water supply, the Government has proposed to construct another 100 mld Sea Water Reverse Osmosis Plant at South of Chennai with the financial assistance of the Government of India. An extent of 40.05 acres of land at Nemmeli Village on East Coast Road has been identified for this project.  Tenders for consultancy for preparation of detailed project report have been received and are under evaluation.  On selection of the consultant and finalization of the detailed project report, the work will be taken up with the financial assistance from Government of India.

24 X 7 UNINTERRUPTED  WATER SUPPLY

Though the CMWSS Board is presently supplying water on daily basis, the water is received by the public either through hand pumps or in the sumps within their premises.  Further, the water is supplied for four to six hours during normal time.  In order to ensure water at reasonable pressure at all times, CMWSS Board has initiated proposals for providing 24x7 uninterrupted water supply to Valluvarkottam Water Distribution Zone in Chennai city on an experimental basis.  The completion of this project will take 3 years duration and on completion, nearly 3,50,000 people under Valluvarkottam Water Distribution Zone will get 24x7 uninterrupted water supply.

    WATER SUPPLY TO ADJACENT LOCAL BODIES WITHIN CHENNAI METROPOLITAN AREA:

             CMWSS Board is supplying drinking water in bulk to the Urban Local Bodies adjacent to Chennai city.   For all these Local Bodies a quantity of about 27 MLD of water is supplied.   The water received from the CMWSS Board is distributed to the consumers by the respective Local Bodies.
