Overview
Sichuan wastewater treatment plant serves Rong County, Zigong, Sichuan, China, with a population of 82,600. It operates under China's national wastewater standards for inland facilities.
The Sichuan wastewater treatment plant is located in Xuyang Town, Rong County, Zigong City, Sichuan Province, China. It serves a population of approximately 82,600, placing it in the medium agglomeration category for Chinese municipal wastewater infrastructure. The plant is situated inland, far from coastal areas, and discharges into local water bodies within the Yangtze River basin. The plant is expected to comply with China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). For medium-sized agglomerations, secondary biological treatment with nutrient removal is typical, especially to protect downstream water quality. Its population served suggests a capacity in the range of 20,000 to 30,000 cubic meters per day. The plant's receiving water body is not explicitly named, but it likely drains into the Tuo River or a tributary of the Yangtze River, which flows through Sichuan. The Yangtze River basin is ecologically significant, supporting diverse aquatic life and providing water for millions. The plant plays a key role in reducing pollution loads to this major river system.
Environmental context
The plant discharges into a tributary of the Yangtze River, likely the Tuo River or Fuxi River, which flows through Zigong and eventually joins the Yangtze. The Yangtze River basin is a critical freshwater ecosystem supporting numerous fish species, including the endangered Chinese sturgeon, and provides drinking water for major cities downstream. The plant's effluent quality directly affects local water quality and the ecological health of the basin.
