Overview
Sichuan wastewater treatment plant serves Chengdu, Sichuan, China, with a population of 148,000. It operates under China's national wastewater standards, ensuring treated effluent meets environmental requirements.
The Sichuan wastewater treatment plant is located in Chengdu, the capital of Sichuan Province, China. It serves a population of approximately 148,000 people, classifying it as a medium-to-large agglomeration under Chinese wastewater management frameworks. The plant is situated in the Longquanyi District, an area undergoing urban development. As a facility serving over 100,000 people, the plant is expected to meet China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), which typically requires secondary treatment with nutrient removal for plants of this scale. The plant's design and operational practices align with national policies aimed at protecting water resources in the densely populated Sichuan Basin. The treated effluent is discharged into local waterways that ultimately flow into the Yangtze River basin, one of China's most ecologically and economically significant river systems. The plant plays a crucial role in reducing pollutant loads to downstream environments, including the Yangtze River's middle and lower reaches, which support diverse aquatic life and provide water for millions of people.
Environmental context
The plant discharges into the Tuo River system, a tributary of the Yangtze River. The Yangtze basin is a critical freshwater ecosystem supporting numerous fish species, including the endangered Chinese sturgeon. Downstream waters flow through densely populated areas before reaching the East China Sea. The plant's operations help mitigate eutrophication risks in the river and coastal zone.
