New Pirana Sewage Treatment Plant 180MLD - Piplaj, Gujarat Wastewater Facility

The New Pirana Sewage Treatment Plant, located in Piplaj near Ahmedabad in Gujarat, India, is a major wastewater treatment facility serving a population of over 1.2 million. It is part of the municipal infrastructure for the Ahmedabad metropolitan area, one of the largest urban agglomerations in western India. As a large-scale plant serving more than 100,000 people, it falls under India's environmental regulations, including the Water (Prevention and Control of Pollution) Act of 1974 and the National Green Tribunal guidelines. Such facilities are expected to meet effluent standards set by the Central Pollution Control Board (CPCB), which mandate secondary treatment as a minimum, with tertiary treatment increasingly required for water reuse or discharge into sensitive water bodies. The plant's treated effluent likely discharges into the Sabarmati River or its tributaries, which flow through Ahmedabad and eventually into the Gulf of Khambhat in the Arabian Sea. The Sabarmati River basin supports diverse aquatic life and is ecologically sensitive due to industrial and urban runoff. Proper treatment at this plant is critical for protecting downstream water quality and the marine environment.

The plant's treated wastewater likely enters the Sabarmati River, which flows through Ahmedabad and drains into the Gulf of Khambhat in the Arabian Sea. This coastal ecosystem supports mangroves, fisheries, and migratory birds, making effective treatment essential to prevent nutrient pollution and protect marine biodiversity.
