Yamunavihar Phase II Wastewater Treatment Plant, Delhi, India

Yamunavihar Phase II is a wastewater treatment plant located in the Yamuna Vihar area of North East Delhi, India. Serving a population of over 300,000, it is a significant facility within Delhi's urban wastewater infrastructure, addressing the needs of a densely populated region. As a large-scale plant in India, it operates under the national regulatory framework, including the Water (Prevention and Control of Pollution) Act, 1974, and the Environment Protection Act, 1986. For agglomerations of this size, secondary treatment is typically required, with possible nutrient removal to protect sensitive water bodies. The plant's treated effluent likely discharges into the Yamuna River, a major tributary of the Ganges, which flows through Delhi and ultimately drains into the Bay of Bengal. The Yamuna is ecologically stressed due to high pollution loads, and this plant contributes to reducing organic and nutrient pollution in the river.

The plant is situated in the Yamuna River basin, with its treated effluent likely entering the Yamuna River, which flows through Delhi and joins the Ganges before reaching the Bay of Bengal. The Yamuna is a critical water source for the region but suffers from significant pollution, making treatment plants like this essential for protecting downstream ecosystems and water quality.
