Solapur Wastewater Treatment Plant, Hotagi, Maharashtra, India

The Solapur wastewater treatment plant is located in Hotagi, a locality in the Solapur district of Maharashtra, India. It was designed to serve a population of approximately 367,466, placing it in the category of a large agglomeration under Indian urban wastewater management norms. The plant is situated near the Shri Siddheshwar Sugar Factory on Hotgi Road. As the plant is currently non-operational, no treatment process or capacity details are available. Under India's regulatory framework, large urban agglomerations are typically required to have secondary or tertiary treatment before discharge, in line with the National Green Tribunal's directives and the Central Pollution Control Board's standards. The plant's non-operational status suggests that wastewater from this population may be untreated or partially treated, posing potential environmental risks. The plant's location in the semi-arid Deccan Plateau region means that local water bodies are seasonal and sensitive to pollution. The nearest major river is the Bhima, a tributary of the Krishna River, which ultimately drains into the Bay of Bengal. The plant's discharge, if untreated, could impact downstream water quality and aquatic ecosystems.

However, the area drains into the Bhima River, a tributary of the Krishna River, which flows into the Bay of Bengal. The Krishna basin supports diverse aquatic life and is a critical water source for agriculture and drinking water in the region. The non-operational status of the plant raises concerns about untreated wastewater entering local streams and groundwater, potentially affecting downstream communities and ecosystems.
