Basan STP - Sewage Treatment Plant in Gandhinagar Taluka, Gujarat, India

Basan STP (Sewage Treatment Plant) is located in Gandhinagar Taluka, Gujarat, India, near the IIT Gandhinagar campus. It serves a population of approximately 13,362 people, placing it in the small-to-medium agglomeration category under Indian urban wastewater management frameworks. The plant has completed construction and is part of the region's sanitation infrastructure. As a sewage treatment plant in India, it operates under the national regulatory framework, including the Water (Prevention and Control of Pollution) Act, 1974, and the Central Pollution Control Board (CPCB) guidelines. For agglomerations of this scale, secondary treatment is typically required, and the plant is expected to meet effluent standards for discharge into inland surface waters or for reuse. The plant's treated effluent likely drains into local water bodies within the Sabarmati River basin, which flows through Gujarat and ultimately into the Gulf of Khambhat (Arabian Sea). The downstream environment supports agricultural and urban water needs, and proper treatment is essential to protect water quality and aquatic life in the region.

The plant is situated in the Sabarmati River basin, which drains into the Gulf of Khambhat in the Arabian Sea. The downstream environment includes agricultural areas and urban settlements that rely on the river for irrigation and domestic use. Effective wastewater treatment helps prevent nutrient loading and contamination, supporting the ecological health of the river and coastal ecosystem.
