Nagasandra Yemalur post Chalaghatta Village STP II - Bengaluru, Karnataka Wastewater Treatment Plant

Nagasandra Yemalur post Chalaghatta Village STP II is a municipal wastewater treatment facility located in Bengaluru, Karnataka, India. The plant serves an estimated population of 64,075 and is situated in the Yamalur area of Bengaluru East City Corporation. It is part of the broader K&C Valley Sewage Treatment Plant complex, which handles wastewater from the surrounding urban catchment. India's wastewater treatment plants are regulated under the Water (Prevention and Control of Pollution) Act, 1974, and the Environment Protection Act, 1986. For a plant serving a medium-sized agglomeration like this, secondary treatment is typically required to meet discharge standards set by the Karnataka State Pollution Control Board (KSPCB). The plant is operational and contributes to the city's wastewater management infrastructure. The treated effluent from the plant is likely discharged into local water bodies that drain into the Dakshina Pinakini River or the Arkavathi River, both of which are part of the Cauvery River basin. The Cauvery River ultimately flows into the Bay of Bengal. The plant plays a key role in protecting downstream water quality and supporting the ecological health of the region's rivers and reservoirs.

The plant's treated effluent enters the local drainage network, which feeds into the Dakshina Pinakini River or Arkavathi River, both tributaries of the Cauvery River. The Cauvery basin supports diverse aquatic life and is a critical water source for agriculture and drinking water in Karnataka and Tamil Nadu. The river ultimately discharges into the Bay of Bengal, making the plant's treatment performance important for coastal water quality.
