New Pirana Sewage Treatment Plant, Vatva Taluka, Ahmedabad, Gujarat

The New Pirana Sewage Treatment Plant is located in Vatva Taluka, Ahmedabad, Gujarat, India. It was designed to serve a large population of approximately 1,215,978 people, classifying it as a major agglomeration under Indian wastewater management standards. In India, large sewage treatment plants typically employ secondary or tertiary treatment technologies such as activated sludge or sequential batch reactors, and are regulated under the Water (Prevention and Control of Pollution) Act, 1974, with oversight by the Gujarat Pollution Control Board. The plant's treated effluent would have discharged into the Sabarmati River, which flows through Ahmedabad and ultimately drains into the Gulf of Khambhat in the Arabian Sea. The river supports diverse aquatic life and is an important water source for the region, making proper wastewater treatment critical for environmental health.

The plant is situated in the Sabarmati River basin, which flows through Ahmedabad and empties into the Gulf of Khambhat, a large tidal estuary on the Arabian Sea. The downstream environment includes agricultural areas and coastal ecosystems that depend on water quality. The river supports diverse aquatic life and is a vital resource for local communities, so effective wastewater treatment is essential to prevent nutrient loading and contamination.
