Keshopur Nilothi II Wastewater Treatment Plant, West Delhi, India

Keshopur Nilothi II is a major wastewater treatment plant located in Patel Nagar, West Delhi, India. Serving a population of over 600,000, it is one of the key facilities in Delhi's extensive wastewater infrastructure, which is essential for managing the sewage of one of the world's most populous cities. The plant operates under India's environmental regulations, including the Water (Prevention and Control of Pollution) Act of 1974 and the National Green Tribunal directives. For a facility of this scale, secondary treatment is typically required, with many large plants in India also incorporating tertiary treatment to meet discharge standards, especially for water reuse or sensitive water bodies. The treated effluent from Keshopur Nilothi II ultimately drains into the Yamuna River, a major tributary of the Ganges. The Yamuna is heavily impacted by urban and industrial pollution, and the plant's performance is crucial for improving water quality in the river, which supports diverse aquatic life and provides water for millions downstream.

Keshopur Nilothi II discharges into the Yamuna River, which flows through Delhi and joins the Ganges in Uttar Pradesh. The Yamuna is a vital water source but suffers from high pollution loads due to urban runoff and untreated sewage. The plant's operations are critical for reducing organic and nutrient loads, helping to protect downstream ecosystems and the Ganges basin, which supports a wide range of aquatic species and provides drinking water for millions.
