KADAPPAKKAM LAKE

AS part of its ongoing efforts to restore ponds and lakes across the city, the Greater Chennai Corporation has now turned to the Nature-Based Solutions (NbS) approach for in at least two places — the Kadapakkam lake and the Sadayakuppam lake.

While the work is almost complete in Kadapakkam, the same approach will now be used in Sadayankuppam.

The NbS, which prioritises eco-restoration by relying on natural methods and avoiding concrete structures while enhancing the well-being of the local community. It also ensures the local community’s rights are not disturbed, a senior corporation official said.

Sadayankuppam in Manali New Town often gets flooded, especially when the Poondi and Puzhal reservoirs are opened during the monsoons. A detailed project report is now being prepared for restoration the lake through NbS approach at an estimated cost of %33 crore.

The lake’s inlet is located in the northern part, and it’s surplus water flows out on the eastern side, about 400m away, into the Kosasthalaiyar river.

Speaking to TNIE, a corporation official said the project involves the construction of sedimentation pond at lake inlet, to protect the water quality and depth of the water body. This helps the sediment-laden soil settle in the inlet before the runoff is discharged.
