Overview
Barave wastewater treatment plant serves Kalyan-Dombivli, Maharashtra, India, with a designed capacity of 1.00 million liters per day, serving over 100,000 people.
The Barave wastewater treatment plant is located in Khadakpada, Kalyan-Dombivli, in the Thane district of Maharashtra, India. It serves a population of approximately 100,218 people, making it a medium-to-large agglomeration under Indian urban wastewater management frameworks. The plant is operational and has a designed capacity of 1.00 million liters per day. As a facility serving over 100,000 people, Barave is subject to India's environmental regulations, including the Water (Prevention and Control of Pollution) Act, 1974, and the National Green Tribunal guidelines. Such plants are expected to provide at least secondary treatment to meet effluent standards before discharge. Typical plants of this scale in Maharashtra employ activated sludge or similar biological treatment. The treated wastewater from Barave likely discharges into local water bodies that drain into the Ulhas River or its tributaries, eventually reaching the Arabian Sea. The plant plays a critical role in protecting the region's water resources and public health by treating sewage from a densely populated urban area.
Environmental context
The Barave plant is located inland, more than 50 km from the coast, in the Ulhas River basin. The Ulhas River flows westward through Maharashtra and empties into the Arabian Sea near Vasai Creek. The river supports diverse aquatic life and is used for irrigation and domestic purposes downstream. Effective wastewater treatment at Barave helps reduce pollution loads in the Ulhas River, protecting both freshwater ecosystems and the coastal environment of the Arabian Sea.
