Dinapur Wastewater Treatment Plant, Varanasi, Uttar Pradesh, India

The Dinapur wastewater treatment plant is a major municipal facility located in Varanasi, Uttar Pradesh, India. Serving a population equivalent of 534,496, it is one of the key treatment plants in the region, supporting the sanitation needs of this historic city on the banks of the Ganges River. As a large agglomeration under India's regulatory framework, the plant is expected to meet secondary treatment standards as per the National Green Tribunal and Central Pollution Control Board guidelines. The treated effluent from Dinapur ultimately discharges into the Ganges River, a critical waterway that flows through the Indo-Gangetic Plain to the Bay of Bengal. The plant plays a vital role in reducing pollution load in the Ganges, supporting aquatic life and downstream communities that depend on the river for water supply and religious practices.

The Dinapur plant discharges into the Ganges River, which flows through Uttar Pradesh and Bihar before emptying into the Bay of Bengal. The Ganges basin supports a dense population and diverse aquatic ecosystems, including species such as the Ganges river dolphin. The plant's effluent management is crucial for maintaining water quality in this ecologically sensitive river, especially given the religious and domestic use of its waters downstream.
