Overview
Chongqing wastewater treatment plant serves 820,000 people in Nan'an 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 Jiguan Stone Town, Nan'an District, Chongqing, China, serving a population of 820,000. As a major municipal facility in one of China's largest municipalities, it plays a critical role in managing wastewater from a densely populated urban area. The plant operates under China's national wastewater discharge standards (GB 18918-2002), which mandate secondary treatment for urban wastewater plants. For a facility serving over 500,000 people, advanced treatment is typically required to meet stringent effluent quality standards, especially given the environmental sensitivity of the receiving waters. The plant discharges treated wastewater into the Yangtze River basin, which ultimately flows into the East China Sea. The Yangtze River is a vital ecological corridor supporting diverse aquatic life and providing water resources for millions downstream. Proper treatment at this facility helps protect water quality in the Three Gorges Reservoir area and downstream ecosystems.
Environmental context
The plant discharges into the Yangtze River basin, which flows through Chongqing and eventually reaches the East China Sea. The Yangtze is one of the world's most biodiverse rivers, supporting numerous fish species and migratory birds. Downstream, the Three Gorges Dam has altered flow regimes, making effective wastewater treatment crucial for maintaining water quality in the reservoir and preventing eutrophication in downstream lakes and coastal zones.
