Titwala East Wastewater Treatment Plant, Kalyan-Dombivli, Maharashtra

Titwala east is a wastewater treatment plant located in Titwala, Kalyan-Dombivli, in the Thane district of Maharashtra, India. It serves a population of approximately 13,362 people within the Kalyan Taluka region. The plant is currently non-operational, and its designed capacity is 1.00 million liters per day. As a plant in India, it falls under the regulatory framework of the Central Pollution Control Board (CPCB) and the Maharashtra Pollution Control Board (MPCB). For agglomerations of this size, secondary treatment is typically required under the Environment Protection Act, 1986, and the Water (Prevention and Control of Pollution) Act, 1974. The plant's treated wastewater would have discharged into local water bodies that ultimately drain into the Ulhas River, which flows into the Arabian Sea near Mumbai. The region's aquatic ecosystems depend on proper wastewater management to prevent pollution and maintain water quality.

The plant is located in the Ulhas River basin, which drains into the Arabian Sea via the Ulhas River estuary. The downstream environment includes mangroves and coastal ecosystems that are sensitive to nutrient loading and industrial pollutants. Proper treatment is essential to protect these habitats and the biodiversity they support.
