The Sichuan wastewater treatment plant is located in Zhoukou, a town in Peng'an County, Nanchong City, Sichuan Province, China. It serves an estimated population of 75,000, classifying it as a medium-sized municipal facility within the region's wastewater infrastructure. China's wastewater treatment regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), mandate secondary treatment with nutrient removal for plants serving populations over 50,000. Facilities of this scale are typically required to meet Class 1-A or 1-B effluent standards, depending on the receiving water body's sensitivity. The plant discharges into the local watershed, which ultimately drains into the Jialing River, a major tributary of the Yangtze River. The Yangtze River basin supports diverse aquatic ecosystems and provides water for millions downstream. Effective treatment at this plant helps protect water quality in the Jialing River and contributes to the ecological health of the broader Yangtze system.
