Overview
Sector 91 wastewater treatment plant serves Noida, Uttar Pradesh, India, with a population equivalent of 33,406. The plant is operational and discharges into the Yamuna River basin, contributing to the Ganges watershed.
Sector 91 is an operational wastewater treatment plant located in Noida, Uttar Pradesh, India, serving a population of approximately 33,406. The plant is situated in the Gautam Buddha Nagar district and plays a key role in managing municipal wastewater for this rapidly urbanizing area within the National Capital Region. As a medium-sized agglomeration, the plant is expected to comply with India's Central Pollution Control Board (CPCB) standards for sewage treatment, which mandate secondary treatment as a minimum. Typical plants of this scale in India employ activated sludge or sequencing batch reactor technologies to meet effluent quality standards. The treated wastewater from Sector 91 ultimately drains into the Yamuna River, a major tributary of the Ganges. The Yamuna is ecologically significant, supporting diverse aquatic life and providing water for irrigation and drinking downstream. The plant's operation is critical for reducing pollution loads in this heavily stressed river system, which flows through densely populated regions before joining the Ganges.
Environmental context
The plant discharges into the Yamuna River basin, which flows through Uttar Pradesh and joins the Ganges River at Triveni Sangam in Prayagraj. The Yamuna is a vital water source but faces significant pollution challenges from urban and industrial runoff. The plant helps mitigate nutrient and pathogen loads, protecting downstream ecosystems and communities that rely on the river for drinking water and agriculture.
