Chennai: Chennai corporation is to implement an integrated stormwater drains (SWD) in Adyar and Cooum basins for expanded areas of the city at an estimated cost of Rs1,117 crore. While the local body has approached the World Bank to fund the project to execute it under the Tamil Nadu Sustainable Urban Development Project (TNS UDP), the fund will also be utilised for restoring Narayanapuram Lake at Pallikaranai at an estimated cost of Rs15.67 crore, officials say.
“The project has been framed in an effort to create storm water drains in the extended areas of the city, as that of the already existing ones in the old areas of Chennai.” In line with this, the corporation has planned to extend it to the Adyar and Cooum basins of the newly added areas, they add.
Though officials admit that the main city still suffers water stagnation even after a slight drizzle because the drain gets ruptured due to illegal sewage lines and diggings by several government agencies. But, the lines in the extended areas were planned better with precast structures, which will not rupture easily and due to pressure, they said.
Several packages have been planned from Adyar and Cooum basins separately. Once, the fund is allocated, the project will be taken up in Ambattur, Valasaravakkam and Alandur, covering other extended areas in phases.The proposed SWD project will be completed in three years from the date of commencement of work.
