Sanpada Wastewater Treatment Plant, Navi Mumbai, Maharashtra

Sanpada wastewater treatment plant is located in Navi Mumbai, Maharashtra, India, along Palm Beach Marg in the Juinagar area. It serves a population of approximately 250,545, classifying it as a large agglomeration under Indian urban wastewater management standards. The plant is operational and plays a key role in managing municipal wastewater for this rapidly growing satellite city of Mumbai. As a large-scale facility, Sanpada is expected to meet treatment standards set by India's Central Pollution Control Board (CPCB) under the Water (Prevention and Control of Pollution) Act, 1974. Plants of this scale typically employ secondary or tertiary treatment to comply with discharge norms. The designed capacity is reported as 1.00 (likely in million liters per day), indicating substantial infrastructure. The plant's treated effluent likely discharges into local water bodies that drain into the Arabian Sea, given its proximity to the coast (within 50 km). This coastal location necessitates stringent treatment to protect marine ecosystems. The surrounding region includes the Thane Creek and Mumbai Harbor, which support diverse aquatic life and are important for local fisheries.

Sanpada plant is situated in the coastal zone of Maharashtra, with treated wastewater potentially flowing into the Thane Creek and ultimately the Arabian Sea. This area supports mangrove ecosystems and estuarine habitats that are critical for fish breeding and migratory birds. Effective treatment is essential to prevent nutrient loading and contamination of these sensitive coastal waters.
