Metro Water Corporation Sewage Treatment Plant, Chennai, India - Municipal Wastewater Facility

The Metro Water Corporation Sewage Treatment Plant is a key wastewater facility serving the Chennai metropolitan area in Tamil Nadu, India. As a municipal plant, it handles sewage from a densely populated urban region, contributing to public health and environmental protection. India's wastewater treatment plants operate under the Water (Prevention and Control of Pollution) Act, 1974, and the Environment Protection Act, 1986. For large urban agglomerations like Chennai, secondary treatment is typically required, with tertiary treatment increasingly adopted for water reuse. The plant's treated effluent likely discharges into the Bay of Bengal via the Cooum River or Adyar River, which flow through Chennai. These rivers are ecologically sensitive, supporting diverse aquatic life and serving as important water sources. The discharge impacts coastal water quality and marine ecosystems in the Bay of Bengal.

The plant is located in Chennai, a coastal city on the Bay of Bengal. Treated wastewater likely enters the Cooum River or Adyar River, which drain into the Bay of Bengal. This coastal environment supports diverse marine life and is a critical habitat for species such as sea turtles and migratory birds. The discharge of treated effluent must comply with Indian standards to protect these ecosystems.
