Sarai Jawalapur Wastewater Treatment Plant, Haridwar, Uttarakhand

Sarai Jawalapur is a wastewater treatment plant located in the Integrated Industrial Estate of Haridwar, Uttarakhand, India. The plant serves a population equivalent of approximately 120,262, making it a medium-to-large agglomeration under Indian urban wastewater management frameworks. It is situated in the holy city of Haridwar, a major pilgrimage center on the banks of the Ganges River. As an operational facility, Sarai Jawalapur is subject to India's environmental regulations, including the Water (Prevention and Control of Pollution) Act of 1974 and the National Green Tribunal guidelines. For a plant of this scale, secondary treatment is typically required, and compliance with effluent standards for discharge into the Ganges is enforced by the Uttarakhand Pollution Control Board. The treated effluent from Sarai Jawalapur ultimately enters the Ganges River, which flows through the Indo-Gangetic Plain and drains into the Bay of Bengal. The Ganges is a vital water resource for millions, supporting agriculture, drinking water, and religious practices. The plant plays a crucial role in reducing pollution loads in this ecologically and culturally significant river system.

Sarai Jawalapur discharges into the Ganges River basin, which flows through the densely populated Indo-Gangetic Plain before reaching the Bay of Bengal. The Ganges supports diverse aquatic life, including the endangered Ganges river dolphin and numerous fish species. The plant's location upstream of major cities like Kanpur and Patna means its effluent quality directly impacts downstream water quality and public health. Effective treatment is critical to mitigate eutrophication and pathogen contamination in this heavily used river.
