Pirana Sewage Treatment Plant 60 MLTD - Maninagar Taluka, Ahmedabad, Gujarat

The Pirana Sewage Treatment Plant is a major wastewater facility located in Maninagar Taluka, Ahmedabad, Gujarat, India. With a population served of approximately 400,872, it is a large-scale municipal treatment plant that plays a critical role in managing the region's wastewater. The plant is situated on Pirana Road, Behrampura, within the compound of a 106 MLD STP, and operates under India's environmental regulations. As a large agglomeration serving over 150,000 people, the plant is expected to meet stringent treatment standards under India's Central Pollution Control Board (CPCB) guidelines. Plants of this scale typically employ secondary or tertiary treatment to comply with discharge norms. The facility's operational status confirms its active role in the local wastewater infrastructure. The treated effluent from the plant is discharged into the local water system, which ultimately drains into the Sabarmati River and then into the Gulf of Khambhat in the Arabian Sea. This downstream pathway highlights the plant's importance in protecting the riverine and coastal ecosystems from untreated sewage. The facility contributes to reducing pollution loads in the Sabarmati, supporting aquatic life and downstream water quality.

The plant's treated wastewater flows into the Sabarmati River, which passes through Ahmedabad and eventually reaches the Gulf of Khambhat in the Arabian Sea. The Sabarmati is a seasonal river that supports diverse aquatic life and is used for irrigation and domestic purposes downstream. The discharge from the plant must meet CPCB standards to prevent eutrophication and protect the estuarine and marine environments near the Gulf of Khambhat, an ecologically sensitive area known for its biodiversity and fisheries.
