Sewage treatment capacity of 478 million litres per day (MLD) has been created in Tamil Nadu under the National River Conservation Plan (NRCP).
Providing this information, a communication from the Centre said that the Union Ministry of Environment and Forests had sanctioned projects to the tune of Rs. 915.93 crore since 2001.
As part of the NRCP, projects for pollution abatement of the rivers of Adyar, Cooum, Cauvery, Tamiraparani, Vaigai and Vennar were implemented in a host of cities and towns including Chennai, Madurai, Tiruchi, Erode, Karur and Mayiladuthurai.
The communication from the National River Conservation Directorate in the Union Ministry last month was in response to a representation sent by N. Ramakrishnan, who is a coordinator of a group of welfare organisations in Tiruchi, to President Pranab Mukherjee, demanding a law for cleaning up the Cauvery.
