Old Pirana Sewage Treatment Plant, Maninagar Taluka, Ahmedabad, Gujarat

The Old Pirana Sewage Treatment Plant, located on Pirana Road in Behrampura, serves the Maninagar Taluka area of Ahmedabad, Gujarat, India. With a population served of over 708,000, it is a major wastewater treatment facility for this densely populated urban region. The plant is operational and plays a critical role in managing the city's sewage. As a large-scale treatment plant in India, it operates under the national regulatory framework of the Central Pollution Control Board (CPCB) and the Gujarat Pollution Control Board (GPCB). For agglomerations of this size, secondary treatment is typically required, and the plant's design and operation align with the standards set by the Water (Prevention and Control of Pollution) Act, 1974. The plant's capacity and treatment processes are designed to handle the high volume of wastewater generated by the population. The treated effluent from the plant is discharged into local water bodies that eventually drain into the Sabarmati River, which flows through Ahmedabad and into the Gulf of Khambhat in the Arabian Sea. The plant's operation is essential for protecting the Sabarmati River and downstream ecosystems from untreated sewage, supporting water quality and public health in the region.

The plant's treated effluent likely discharges into the Sabarmati River, which flows through Ahmedabad and into the Gulf of Khambhat, a coastal inlet of the Arabian Sea. The Sabarmati River supports diverse aquatic life and is an important water source for the region. The plant's operation helps mitigate pollution in this river, protecting downstream ecosystems and the coastal environment.
