Overview
564 MLD WWTP Okhla is an operational wastewater treatment plant serving the Okhla area of Delhi, India. It treats sewage from a large urban population before discharging into the Yamuna River.
564 MLD WWTP Okhla is a major wastewater treatment facility located in the Okhla area of Delhi, India. It serves a large urban agglomeration, treating sewage from residential and commercial sources. The plant is one of several large-scale treatment facilities in the Delhi region, reflecting the city's extensive wastewater management infrastructure. As a large treatment plant with a capacity of 564 million liters per day, it operates under India's environmental regulations, which mandate secondary treatment for urban wastewater. Its operational status indicates it is actively contributing to pollution control in the Yamuna River basin. The treated effluent from the plant is discharged into the Yamuna River, a major tributary of the Ganges. The Yamuna flows through Delhi and downstream to the Ganges, ultimately reaching the Bay of Bengal. The plant plays a critical role in reducing organic and nutrient pollution in the river, which supports diverse aquatic life and is used for irrigation and drinking water downstream.
Environmental context
The plant discharges into the Yamuna River, which flows through Delhi and joins the Ganges in Uttar Pradesh. The Yamuna is heavily polluted due to urban and industrial discharges, and this plant helps mitigate some of that load. Downstream, the Ganges supports a vast ecosystem and provides water for millions of people. The plant's operation is crucial for improving water quality in this densely populated and ecologically sensitive river basin.
