Overview
Sichuan wastewater treatment plant serves Wenjiang District, Chengdu, Sichuan, China, with a population of 610,000. It operates under China's national wastewater standards.
The Sichuan wastewater treatment plant is located in Wenjiang District, Chengdu, Sichuan Province, China. It serves a population of approximately 610,000, classifying it as a large-scale municipal facility within the region's urban wastewater infrastructure. As a major treatment plant in China, it is subject to the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits for conventional pollutants and nutrients. For plants of this scale, advanced treatment with nutrient removal is typically required to protect receiving waters. The plant discharges treated effluent into local water bodies that ultimately drain into the Yangtze River basin, a critical freshwater resource for eastern China. Proper treatment helps safeguard downstream aquatic ecosystems and water quality for communities relying on the river system.
Environmental context
The plant's treated effluent flows into the Min River system, a major tributary of the Yangtze River. The Yangtze basin supports diverse aquatic life and provides drinking water for millions. Effective nutrient removal at this plant helps prevent eutrophication in downstream lakes and reservoirs, maintaining ecological balance in this densely populated region.
