Keshopur Nilothi I Wastewater Treatment Plant, Delhi, India

Keshopur Nilothi I is a wastewater treatment plant located in Patel Nagar, West Delhi, Delhi, India. It serves a population of approximately 360,785, classifying it as a large agglomeration under Indian urban wastewater management standards. As a plant of this scale in India, it operates under the regulatory framework of the Central Pollution Control Board (CPCB) and the Delhi Pollution Control Committee (DPCC), which mandate treatment standards for municipal wastewater. Plants of this size typically employ secondary or tertiary treatment to meet discharge norms. The treated effluent from the plant is discharged into local water bodies that eventually drain 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 domestic use downstream. The plant plays a crucial role in reducing pollution load in this sensitive river system.

The plant discharges into the Yamuna River basin, which flows through Delhi and ultimately joins the Ganges. The Yamuna is a vital water source but faces significant pollution challenges from urban and industrial runoff. The plant's operation helps mitigate nutrient and pathogen loading, supporting aquatic biodiversity and downstream water quality for communities and agriculture.
