Overview
Chongqing wastewater treatment plant serves 212,000 people in Shatang Village, Changshou District, Chongqing, China. The facility operates under China's national wastewater standards, discharging treated effluent into the Yangtze River basin.
The Chongqing wastewater treatment plant is located in Shatang Village, Changshou District, Chongqing, China, serving a population of 212,000. As a medium-to-large agglomeration, the plant plays a key role in managing municipal wastewater in the rapidly urbanizing region of southwestern China. The plant operates under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which sets effluent limits based on receiving water sensitivity. For plants of this scale, secondary treatment with nutrient removal is typical, especially given the proximity to the Yangtze River system. The plant discharges into the Yangtze River basin, the third-longest river in the world, which flows eastward through central China to the East China Sea near Shanghai. The downstream environment includes ecologically sensitive areas such as the Three Gorges Reservoir region, which supports diverse aquatic life and requires strict pollution control to protect water quality and biodiversity.
Environmental context
The plant discharges into the Yangtze River basin, which flows through Chongqing and continues eastward to the East China Sea. The downstream environment includes the Three Gorges Reservoir, a critical freshwater ecosystem that supports migratory fish species and provides drinking water for millions. Nutrient and pollutant loads from upstream sources must be carefully managed to prevent eutrophication and protect aquatic habitats.
