Chehadi 2 Wastewater Treatment Plant, Deolali, Maharashtra, India

Chehadi 2 is a wastewater treatment plant located in Deolali, a town in the Nashik district of Maharashtra, India. The plant serves a population of around 133,624, classifying it as a medium-to-large agglomeration under Indian urban wastewater management standards. It is part of the municipal infrastructure for the Nashik region, which includes both urban and peri-urban areas. As an operational facility, Chehadi 2 is expected to comply with India's Central Pollution Control Board (CPCB) norms for sewage treatment. For agglomerations of this scale, secondary treatment is typically required, with possible nutrient removal if discharging into sensitive water bodies. It operates under the regulatory framework of the Maharashtra Pollution Control Board (MPCB), which issues consent-to-operate permits and monitors effluent quality. The treated wastewater from Chehadi 2 likely discharges into a local watercourse that eventually drains into the Godavari River basin, as the Nashik region lies within the upper Godavari catchment. The Godavari is a major river in central India, supporting agriculture, drinking water, and diverse aquatic ecosystems downstream. Proper treatment at Chehadi 2 helps protect water quality in the river system and downstream communities.

Chehadi 2 discharges into a local tributary that flows into the Godavari River, one of India's largest rivers, which ultimately empties into the Bay of Bengal. The Godavari basin supports extensive agriculture, fisheries, and biodiversity, including several fish species and migratory birds. The plant's location in the upper catchment means its effluent quality directly affects downstream water availability and ecological health, particularly during dry seasons when dilution is limited.
