Overview
Mothorowala wastewater treatment plant under construction in Dehradun, Uttarakhand, India, designed to serve over 133,000 people in the Doon Valley region.
Mothorowala wastewater treatment plant is located on Doon University Road in Dehradun, Uttarakhand, India. Currently under construction, the facility is designed to serve a population of approximately 133,624, making it a large-scale municipal treatment project for the Dehradun urban area. As a plant of this scale in India, it is expected to comply with the Central Pollution Control Board (CPCB) norms for sewage treatment, which mandate secondary or tertiary treatment depending on the receiving water body. The plant will likely incorporate biological treatment processes to meet effluent standards before discharge. The treated wastewater from Mothorowala will ultimately drain into the Ganges River basin via local streams, contributing to the protection of this major river system. The Doon Valley's unique ecology and downstream aquatic life will benefit from reduced pollution loads once the plant becomes operational.
Environmental context
The plant serves Dehradun in the Doon Valley, which drains into the Ganges River basin via the Song and Suswa rivers. These rivers support diverse aquatic life and are part of a larger watershed that provides water for millions downstream. Effective treatment here helps reduce nutrient and pathogen loads entering the Ganges, protecting both human health and freshwater biodiversity.
Frequently asked questions
The Mothorowala wastewater treatment plant is located on Doon University Road in Dehradun, Uttarakhand, India, with coordinates 30.262 N, 78.042 E.
The plant is designed to serve a population of 133,624, covering a significant portion of Dehradun's urban area.
The treated wastewater from Mothorowala is expected to be discharged into local streams that flow into the Song and Suswa rivers, which are part of the Ganges River basin.
In India, sewage treatment plants of this scale are regulated by the Central Pollution Control Board (CPCB) under the Water (Prevention and Control of Pollution) Act, 1974, which sets effluent standards for discharge into water bodies.
For a plant of this size in India, secondary treatment (biological process) is standard, and tertiary treatment may be required if discharging into sensitive water bodies like the Ganges.
