Overview
Sichuan wastewater treatment plant serves Emeishan City, Sichuan Province, China, with a population of 170,800. It operates under China's national wastewater discharge standards.
The Sichuan wastewater treatment plant is located in Emeishan City, Leshan, Sichuan Province, China. It serves a population of approximately 170,800, classifying it as a medium-to-large agglomeration under Chinese wastewater management frameworks. The plant is situated in the inland region of Sichuan, near the Li River (李河坝), and plays a key role in treating municipal wastewater from the urban area. Under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), plants serving populations of this scale are typically required to meet Class 1-A or Class 1-B standards, which mandate secondary treatment with nutrient removal. The regulatory framework ensures that facilities of this size are designed to handle significant organic and nutrient loads to protect receiving waters. The treated effluent is discharged into local water bodies that eventually flow into the Yangtze River basin via the Min River system. The downstream environment includes agricultural areas and ecologically sensitive zones that depend on good water quality. Proper treatment at this plant helps reduce pollution loads to the Yangtze River and its tributaries, supporting aquatic biodiversity and downstream water uses.
Environmental context
The plant discharges into local waterways that are part of the Min River system, a major tributary of the Yangtze River. The downstream environment includes agricultural lands and ecologically important wetlands that support diverse aquatic life. Effective wastewater treatment is critical to prevent eutrophication and protect the water quality of the Yangtze River basin, which is a vital freshwater resource for millions of people and numerous species.
