Villivakkam Sewage Treatment Plant - Chennai, Tamil Nadu Wastewater Facility

Villivakkam Sewage Treatment Plant is located in the Villivakkam neighborhood of Chennai, Tamil Nadu, India. It is part of the city's extensive wastewater infrastructure, serving a densely populated urban area. The plant is operational and contributes to the management of domestic sewage from the surrounding region. As a municipal treatment facility in India, the plant operates under the national environmental regulations, including the Water (Prevention and Control of Pollution) Act, 1974, and the Environment Protection Act, 1986. These frameworks mandate treatment standards for wastewater discharge to protect water resources. For urban agglomerations like Chennai, secondary treatment is typically required, and the plant likely employs conventional biological processes. The treated effluent from the plant is discharged into local water bodies that drain into the Bay of Bengal via the Cooum River or other nearby waterways. This discharge impacts the coastal ecosystem, including the sensitive marine environment of the Bay of Bengal, which supports diverse aquatic life and fisheries.

The plant's treated effluent flows into the Cooum River, which traverses Chennai and empties into the Bay of Bengal. The Bay of Bengal is a major marine ecosystem supporting rich biodiversity, including coral reefs, mangroves, and important fisheries. Discharge from urban treatment plants can affect water quality and aquatic health in the river and coastal zone.
