Sichuan Wastewater Treatment Plant, Fushun County, Sichuan Province

The Sichuan wastewater treatment plant is located in Fushun County, part of Zigong City in Sichuan Province, China. It serves a population equivalent of 96,100, placing it in the medium-to-large agglomeration category. The plant is situated inland, away from coastal areas, and its operations are governed by China's national wastewater discharge standards. Under China's regulatory framework, wastewater treatment plants serving populations over 50,000 are typically required to achieve secondary treatment or higher, with nutrient removal in sensitive watersheds. The scale suggests compliance with national standards for urban wastewater management. The treated effluent is discharged into local water bodies that eventually drain into the Yangtze River basin, a critical freshwater resource for the region. The plant plays a key role in protecting downstream aquatic ecosystems and supporting water quality in the densely populated Sichuan Basin.

The plant discharges into local waterways that flow into the Yangtze River system, which ultimately reaches the East China Sea. The downstream environment includes ecologically sensitive areas that support diverse aquatic life and provide water for agriculture and urban use. Protecting water quality in this basin is essential for regional ecological health and human well-being.
