Chehadi 1 Wastewater Treatment Plant, Deolali, Maharashtra

Chehadi 1 is a wastewater treatment plant located in Deolali, a town in the Nashik district of Maharashtra, India. The plant serves a population of about 147,000, placing it in the category of a medium-to-large agglomeration under Indian urban wastewater management frameworks. The plant operates under India's Water (Prevention and Control of Pollution) Act, 1974, and the Environmental Protection Rules, which mandate treatment standards for municipal wastewater. Plants of this scale are typically expected to provide at least secondary treatment to meet discharge norms set by the Central Pollution Control Board (CPCB). The treated effluent from Chehadi 1 likely discharges into a local watercourse that eventually drains into the Godavari River basin, as the region is part of the Godavari catchment. The Godavari is a major river in central India, supporting diverse aquatic ecosystems and providing water for agriculture and domestic use downstream.

Chehadi 1 is situated in the Godavari River basin, one of India's largest river systems. The treated wastewater likely flows into a local tributary that joins the Godavari, which ultimately empties into the Bay of Bengal. The Godavari supports a rich diversity of fish and other aquatic life, and its delta is an ecologically sensitive area. Proper treatment of wastewater is crucial to prevent nutrient loading and contamination that could affect downstream communities and ecosystems.
