Overview
Sichuan wastewater treatment plant serves Qianwei County, Leshan, Sichuan, China, with a population of 51,300. The plant is located inland, over 50 km from the coast.
The Sichuan wastewater treatment plant is located in Qianwei County, Leshan City, Sichuan Province, China. It serves a population of approximately 51,300, classifying it as a medium-sized agglomeration under typical Chinese municipal wastewater management frameworks. The plant operates under China's national wastewater discharge standards, which require secondary treatment for urban wastewater treatment plants. For plants serving populations between 10,000 and 100,000, secondary treatment with nutrient removal is commonly expected to protect receiving water bodies. The plant discharges into the local watershed, which ultimately drains into the Yangtze River basin via the Min River system. This region is ecologically significant, supporting diverse aquatic life and providing water for agricultural and urban use downstream.
Environmental context
The plant's treated effluent flows into the Min River, a tributary of the Yangtze River, which is one of the most important river systems in China. The downstream environment includes agricultural areas and urban centers that rely on the river for water supply. The watershed supports diverse fish species and is an important ecological corridor in Sichuan Province.
