Koyambedu B Wastewater Treatment Plant, Chennai, Tamil Nadu

Koyambedu B is a municipal wastewater treatment plant located in the Kodambakkam zone of Chennai, Tamil Nadu, India. It is currently under construction and is designed to serve a population of 801,744, making it a large-scale facility critical to Chennai's urban sanitation infrastructure. As a plant under construction, its treatment process and capacity details are not yet finalized. Once operational, it will be subject to India's environmental regulations, including the Water (Prevention and Control of Pollution) Act, 1974, and likely require compliance with standards set by the Tamil Nadu Pollution Control Board (TNPCB). For a facility of this scale, advanced treatment may be expected to meet discharge norms. The plant's treated effluent will likely be discharged into local water bodies that drain into the Bay of Bengal. Chennai's coastal location means the plant's operations will be important for protecting both inland waterways and the marine environment from pollution.

The plant is located in Chennai, a coastal city on the Bay of Bengal. Treated wastewater from the facility will likely be discharged into the Cooum River or other local waterways that flow into the Bay of Bengal. This coastal discharge zone supports diverse marine life and is important for local fisheries, making effective treatment essential to prevent eutrophication and protect aquatic ecosystems.
