Erandawane Wastewater Treatment Plant, Anandnagar, Pune, Maharashtra

Erandawane wastewater treatment plant is located in Anandnagar, a locality within Pune city, Maharashtra, India. The plant serves a population of approximately 334,060, placing it in the category of a large agglomeration under Indian urban wastewater management standards. It is situated in the western part of Pune, near the Mula-Mutha river system. As a large-scale facility, Erandawane is expected to comply with the Central Pollution Control Board (CPCB) norms for sewage treatment, which mandate secondary treatment as a minimum, with tertiary treatment required for discharge into sensitive water bodies. The plant's operational status confirms its role in managing municipal wastewater from the surrounding residential and commercial areas. The treated effluent from the plant likely discharges into the Mula-Mutha river, which flows through Pune and eventually joins the Bhima River, a tributary of the Krishna River. This river system supports diverse aquatic life and is used for irrigation and domestic purposes downstream. The plant's performance is critical for maintaining water quality in the Krishna basin.

The Erandawane plant discharges into the Mula-Mutha river system, which flows through Pune and merges with the Bhima River, part of the larger Krishna River basin. The Krishna River ultimately drains into the Bay of Bengal. The downstream environment supports agricultural activities and provides habitat for fish and other aquatic species. Effective treatment at this plant helps reduce nutrient and pathogen loads, protecting both human health and ecological integrity in the basin.
