GCC to Build Rs 41-Crore Stormwater Drain to Prevent Floods in Anna Nagar West

The Greater Chennai Corporation is set to begin construction of a stormwater drain network connecting Otteri Nullah Zero Point to the Cooum river along Jawaharlal Nehru Salai to mitigate flooding in Anna Nagar West and surrounding western parts of the city.

The project was announced on Monday during the Tamil Nadu Budget session for the Municipal Administration and Water Supply Department. The drain will be built at an estimated cost of ₹41 crore with financial assistance from a German bank.

According to municipal plans, the drain construction is designed to prevent flood-related issues during the monsoon season across several contiguous western localities, including Villivakkam, Ambattur, Korattur, Padi, and Anna Nagar West.

The initiative was presented as part of a wider package of urban infrastructure and sanitation projects undertaken for Chennai and its adjoining urban local bodies under the Chief Minister’s Integrated Urban Development Mission (CMIUDM) and other municipal programmes.

Connecting Otteri Nullah Zero Point directly to the Cooum river along the Jawaharlal Nehru Salai corridor is intended to facilitate the smooth discharge of surplus rainwater and provide long-term flood relief to residential and commercial neighbourhoods across the western belt.
