Overview
STP Nazafgarh is a municipal wastewater treatment plant in Delhi, India, serving over 150,000 people. It is operational and plays a key role in managing sewage from the Najafgarh area.
STP Nazafgarh is a wastewater treatment plant located in the Najafgarh area of South West Delhi, India. Serving a population of approximately 150,327, it is a significant facility within Delhi's urban wastewater infrastructure, handling sewage from a densely populated part of the city. As a plant serving a large agglomeration, it operates under India's environmental regulations, which mandate treatment standards for such facilities. The treated effluent from STP Nazafgarh ultimately drains into the Yamuna River, a major tributary of the Ganges. The Yamuna is heavily impacted by urban and industrial discharges, making the plant's role critical for improving water quality in the river and downstream ecosystems.
Environmental context
STP Nazafgarh discharges into the Yamuna River, which flows through Delhi and joins the Ganges in Uttar Pradesh. The Yamuna is a vital water source but faces severe pollution from untreated sewage and industrial effluents. The plant helps mitigate this by treating wastewater from a large population, supporting aquatic life and reducing health risks downstream.
