Overview
Sichuan wastewater treatment plant serves Xinjin District, Chengdu, Sichuan, China, with a population equivalent of 52,900. It operates under China's national wastewater discharge standards.
The Sichuan wastewater treatment plant is located in Baodun Town, Xinjin District, Chengdu, Sichuan Province, China. It serves a population equivalent of approximately 52,900, classifying it as a medium-sized municipal facility within the region's growing urban infrastructure. The plant operates under China's national wastewater discharge standards (GB 18918-2002), which mandate secondary treatment with nutrient removal for facilities of this scale. The plant's design and operation align with the country's broader efforts to improve water quality in rapidly urbanizing areas. The treated effluent is discharged into local waterways that ultimately drain into the Yangtze River basin, one of the world's most ecologically significant river systems. The plant plays a crucial role in protecting downstream aquatic habitats and supporting water quality in the densely populated Sichuan Basin.
Environmental context
The plant discharges into tributaries of the Min River, a major branch of the upper Yangtze River. The receiving waters support diverse aquatic life and are important for regional agriculture and drinking water supplies. Downstream, the Yangtze River flows through ecologically sensitive areas including wetlands and fish spawning grounds, making effective wastewater treatment critical for maintaining water quality and ecosystem health.
