CHENNAI: Thiruvottiyur, Manali, Sholinganallur and five other areas added to the city corporation in 2011 can hope for some respite from waterlogging around five years from now, with the civic body preparing to execute a massive Rs 4,034-crore project for a storm water drain network in these neighbourhoods.
The integrated network, covering more than 250 sqkm, will drain rainwater into the city rivers that will carry it to the sea. The corporation, however, has not revealed if the drains will be connected to rainwater harvesting systems to replenish aquifers in the city where the groundwater levels have plummeted.
These areas will also get an underground sewerage network at an estimated Rs 400 crore, the government announced in the assembly on Friday.
"We will start work on the integrated storm water drain system by the end of this calendar year or at the end of this fiscal. It will take five years to complete," a senior corporation official said. Over the period of construction, the cost is likely to escalate to 5,313 crore, according to estimates in a detailed project report, making it one of the corporation's biggest projects.
Residents of the areas expected to benefit from the drain network welcomed the announcement. "This promises great relief to several areas where life comes to a standstill whenever it rains," said Ravindran Narayanan, of Ambattur. "Since this is not a low-lying area, water always flows from here and collects in Mogappair East."
The public works department in 2009 started work on a storm water drain project to prevent flooding with funding of 1,448 crore from the Jawaharlal Nehru National Urban Renewal Mission ( JNNURM). The work is still in progress.
"The project will augment the existing storm water drain network by 1,069.4km," the official said. The project area is divided into four drainage basins, Kosasthalaiyar (originating in Vellore), Cooum, Adyar and Kovalam.
