Overview
Okhla Phase V is a large municipal wastewater treatment plant in Delhi, India, serving over 480,000 people. It operates under India's environmental regulations for sewage treatment.
Okhla Phase V is a major sewage treatment plant located in the Okhla area of South East Delhi, India. Serving a population of approximately 481,000, it is one of several plants managing the city's wastewater. The plant is operational and plays a key role in Delhi's sanitation infrastructure. As a large-scale treatment facility in India, Okhla Phase V is subject to the Central Pollution Control Board (CPCB) norms, which mandate secondary treatment for urban agglomerations. The plant's treatment process and capacity details are not publicly available, but facilities of this scale typically employ biological treatment methods such as activated sludge or sequencing batch reactors. The treated effluent from Okhla Phase V is likely discharged into the Yamuna River, a major tributary of the Ganges. The Yamuna is heavily polluted in the Delhi stretch, and the plant's operations are critical for reducing organic load and protecting downstream ecosystems. The river ultimately drains into the Bay of Bengal via the Ganges-Brahmaputra delta.
Environmental context
The plant's treated effluent likely enters the Yamuna River, which flows through Delhi and merges with the Ganges in Uttar Pradesh. The Yamuna is a vital water source but suffers from high pollution levels due to urban and industrial discharges. Downstream, the Ganges supports diverse aquatic life and is a critical water source for millions. The plant's performance directly impacts the river's health and the ecological balance of the Ganges basin.
