Sangvi Phase I Wastewater Treatment Plant, Pimpri-Chinchwad, Maharashtra

Sangvi Phase I is a municipal wastewater treatment plant located in the Sangvi area of Pimpri-Chinchwad, a twin city in the Pune district of Maharashtra, India. The plant serves a population of approximately 100,218, placing it in the category of a large agglomeration under Indian urban wastewater management standards. It is situated in the rapidly urbanizing Pune metropolitan region, which has seen significant industrial and residential growth. As a plant serving over 100,000 people, Sangvi Phase I is expected to meet the treatment 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 typically required, and in sensitive areas, tertiary treatment may be mandated. The plant's operational status indicates it is actively managing wastewater from the surrounding community. The treated effluent from Sangvi Phase I likely discharges into local streams that feed into the Mula-Mutha River system, which flows through Pune and eventually joins the Bhima River, a tributary of the Krishna River. The Krishna River drains into the Bay of Bengal. The plant plays a crucial role in protecting the water quality of these rivers, which support diverse aquatic life and are used for irrigation and domestic purposes downstream.

Sangvi Phase I discharges into the Mula-Mutha River system, which flows through Pune and joins the Bhima River, a major tributary of the Krishna River. The Krishna River ultimately drains into the Bay of Bengal. The plant helps protect the ecological health of these rivers, which support aquatic biodiversity and provide water for agriculture and drinking. The region experiences a tropical monsoon climate, with heavy rainfall during the monsoon season, making effective wastewater treatment essential to prevent pollution during high-flow events.
