Overview
Nagasandra Yemalur post Chalaghatta Village STP I is an operational wastewater treatment plant in Bengaluru, Karnataka, India, serving approximately 64,000 people.
Nagasandra Yemalur post Chalaghatta Village STP I is a municipal wastewater treatment plant located in Bengaluru, Karnataka, India. The plant serves a population of approximately 64,075 and is part of the city's extensive sewerage infrastructure managed by the Bangalore Water Supply and Sewerage Board (BWSSB). As a plant serving a medium-sized agglomeration in India, it operates under the national environmental regulations, including the Water (Prevention and Control of Pollution) Act of 1974 and the Environment Protection Act of 1986. Indian wastewater treatment plants of this scale are typically expected to provide secondary treatment, with standards set by the Central Pollution Control Board (CPCB) for discharge into inland surface waters. The plant's treated effluent is discharged into the local drainage system, which ultimately flows into the Dakshina Pinakini River or the South Pennar River basin. This water body supports agricultural and domestic uses downstream and is part of the larger Cauvery basin ecosystem. The plant plays a crucial role in protecting local water quality and public health in the rapidly urbanizing Bengaluru region.
Environmental context
The plant discharges into the Dakshina Pinakini River basin, which flows through Karnataka and Tamil Nadu before reaching the Bay of Bengal. This river system supports irrigation and drinking water supplies for downstream communities. The surrounding watershed is ecologically sensitive due to rapid urbanization and industrial activity, making effective wastewater treatment essential for maintaining water quality and aquatic biodiversity.
