Chennai City River Conservation Project

Government of Tamil Nadu jointly with Ministry of Environment and Forest (National River Conservation Directorate), Government of India undertook a comprehensive study examining the cause of pollution of the water ways and its impact on the environment and formulated "Chennai City River Conservation Project".

Chennai City has six waterways viz. Adyar, Cooum, Buckingham canal, Otteri Nullah, Captain Cotton Canal and Mambalam Drain.

Essentially these river functions as a flood carriers and have flows for about 2 months during monsoon. During the remaining part of the year the flow is mainly due to discharge of treated, partially treated and untreated sewage through about 311 out falls meant for storm water discharge, resulting in accumulation of large volume of sludge and formation of sand bar in the mouth of rivers. These overflows have created significant problems for flood protection system, storm water drain net works and public health leading to over all environmental degradation. Hence, long term objective of the project is to holistically improve the waste water or sewage disposal network so as to prevent noxious substances from reaching the water ways.

The project aims to provide the following.

  • Interceptor sewers along River banks.
  • Increasing Pumping Potential of Sewage Pumping Stations.
  • To achieve 100% effluent Standards of Sewage Treatment Plants as per the Tamil Nadu Pollution Control Board's norms.
  • To increase the coverage of Agro-Forestry with treated sewage.
  • To set up nursery of saplings of Agro-Forestry at Sewage Treatment Plants.

Moreover, the capacity of the existing sewer system has become grossly inadequate and is in need of major improvements, if the discharge of untreated and partially treated sewage into the City Water Ways is to be prevented.

The components pertaining to interception, diversion and treatment of sewage costing Rs.720.15 crores (prevention of raw and untreated sewage flow to water courses) would be implemented by CMWSSB and supported by the Govt. of India, Ministry of Environment and Forests, National River Conservation Directorate (NRCD) on the following funding pattern:

1. Grant from NRCD - Rs.491.52 Crores

2. Internal generation by CMWSSB - Rs.228.63 Crores

This comprises of "Interception, Diversion and Treatment of Sewage" in all the five zones and providing additional 264 mld capacity of sewage treatment plants in four locations. The works are planned to be executed in 16 Packages.

Out of the total CCEA approved cost of Rs.491.52 crores, the works were taken up under 16 Packages at an estimated cost of Rs.382.24 crores with a savings of Rs.109.28 crores.

Subsequently, NRCD has approved the Additional Works amountings to Rs2215.78 lakhs for expansion capacity and strengthening of sewerage system covering the necessary stretches utilizing the savings of Rs.109.28 crores under CCRCP. The project cost of these additional works has to be shared by the Government of India and Government of Tamilnadu in 70:30 ratios repectively.
