Overview
Sichuan wastewater treatment plant serves Shuangliu District, Chengdu, Sichuan, China, with a population of 28,200. The plant discharges into local waterways within the Yangtze River basin.
The Sichuan wastewater treatment plant is located in Shuangliu District, Chengdu, Sichuan Province, China. It serves a population of approximately 28,200, placing it in the small-to-medium agglomeration category under Chinese wastewater regulations. China's wastewater treatment standards are governed by the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which mandates secondary treatment with nutrient removal for plants of this scale. Typical facilities in this region employ activated sludge processes to meet Class 1A or 1B effluent standards. The plant discharges into local rivers that ultimately flow into the Yangtze River basin, one of China's most important water systems. The Yangtze supports diverse aquatic life and provides water for millions of people downstream. Proper treatment at this plant helps protect water quality in the densely populated Sichuan Basin.
Environmental context
The plant discharges into the local river network within the Yangtze River basin. The Yangtze River flows eastward through central China before emptying into the East China Sea near Shanghai. This watershed supports extensive agriculture, urban populations, and ecologically sensitive wetlands along its course. The Sichuan Basin, where the plant is located, is a major agricultural and industrial region, making effective wastewater treatment critical for maintaining downstream water quality and aquatic ecosystem health.
