Kochilaput Wastewater Treatment Plant, Bhubaneswar, Odisha

Kochilaput is a wastewater treatment plant currently under construction in the South West Zone of Bhubaneswar Municipal Corporation, Odisha, India. Serving a population of 290,632, the plant is designed with a capacity of 1.00 million liters per day, addressing the growing wastewater management needs of this urban area. As a plant under construction, its treatment process is not yet operational. In India, wastewater treatment plants of this scale are typically required to meet standards set by the Central Pollution Control Board (CPCB) under the Water (Prevention and Control of Pollution) Act, 1974. For large agglomerations, secondary treatment is standard, with tertiary treatment increasingly adopted for water reuse. The plant will discharge treated wastewater into local water bodies that ultimately drain into the Bay of Bengal via the Mahanadi River delta. This coastal region supports diverse aquatic ecosystems and is important for fisheries and agriculture. Proper treatment is essential to protect downstream water quality and ecological health.

The plant lies within the Mahanadi River basin, which drains into the Bay of Bengal. The downstream environment includes the Mahanadi delta, a region of mangroves and wetlands that supports diverse aquatic life and migratory birds. Treated effluent from the plant will contribute to maintaining water quality in this ecologically sensitive coastal zone.
