Chongqing Wastewater Treatment Plant, Datong Town, Qijiang District

The Chongqing wastewater treatment plant is located in Datong Town, Qijiang District, within the municipality of Chongqing, China. It serves a population of approximately 7,000 residents, classifying it as a small-scale municipal facility. The plant is part of the broader wastewater infrastructure supporting this inland region. As a small agglomeration, the plant is expected to meet China's national discharge standards for urban wastewater treatment, which typically require secondary treatment or equivalent. The facility's design and operation align with the country's regulatory framework for water pollution control, ensuring treated effluent meets environmental quality standards before discharge. The plant's treated effluent likely discharges into a local watercourse within the Yangtze River basin, as Chongqing is situated along the upper reaches of the Yangtze. This river system supports diverse aquatic life and provides water for downstream communities. The plant plays a key role in protecting local water quality and the ecological health of the region's waterways.

The plant is located in the Yangtze River basin, one of China's most important watersheds. Treated effluent likely enters a tributary of the Yangtze, which flows through Chongqing and eventually reaches the East China Sea. The Yangtze supports a rich diversity of fish species and provides drinking water for millions. Protecting this river from nutrient pollution and contaminants is critical for both ecological balance and human use.
