Narela II Wastewater Treatment Plant, Delhi, India

Narela II is a wastewater treatment plant located in Metro Vihar, Narela Tehsil, North Delhi, Delhi, India. It serves a population of 3,608 and is part of Delhi's municipal wastewater network, which manages sewage from the rapidly urbanizing capital region. The plant is operational and plays a role in treating local domestic wastewater. As a small-scale facility in India, Narela II operates under the country's environmental regulations, including the Water (Prevention and Control of Pollution) Act of 1974 and the National Green Tribunal guidelines. Indian treatment plants of this size typically employ secondary treatment processes such as activated sludge or oxidation ponds to meet effluent standards set by the Central Pollution Control Board. The treated effluent from Narela II likely discharges into local drains that eventually flow into the Yamuna River, a major tributary of the Ganges. The Yamuna is heavily impacted by urban and industrial pollution, making effective treatment crucial for downstream water quality and the ecological health of the Ganges basin.

Narela II discharges treated wastewater into the Yamuna River basin, which flows through Delhi and eventually joins the Ganges River. The Yamuna is a vital water source but suffers from high pollution loads due to urban runoff and untreated sewage. Effective treatment at plants like Narela II helps reduce organic and nutrient pollution, supporting aquatic life and downstream water quality in the Ganges delta.
