Overview
Sichuan wastewater treatment plant serves Suining, Sichuan, China, with a population of 53,300. The plant operates under China's national wastewater standards.
The Sichuan wastewater treatment plant is located in Suining, Sichuan Province, China, serving a population of approximately 53,300. Situated in the urban area of Chuanshan District, the plant is part of the municipal infrastructure managed by local authorities. China's wastewater treatment regulations require secondary treatment for urban plants serving populations over 50,000, with discharge standards aligned to the Environmental Quality Standards for Surface Water. The plant's scale places it in the medium agglomeration category, where treatment typically includes biological processes and nutrient removal to meet Class 1A or 1B standards. The treated effluent is discharged into local waterways that eventually flow into the Fu River, a tributary of the Jialing River, which joins the Yangtze River. This downstream connection makes the plant's performance important for the water quality of the Yangtze basin, supporting aquatic ecosystems and downstream water uses.
Environmental context
The plant discharges into the Fu River system, which flows into the Jialing River and ultimately the Yangtze River. The Yangtze basin supports diverse aquatic life and provides water for millions of people. Effective treatment at this plant helps reduce nutrient and pollutant loads, protecting downstream habitats and water quality in this ecologically significant river system.
