Chongqing Wastewater Treatment Plant - Shizhu, Chongqing, China

The Chongqing wastewater treatment plant is located in Wan'an Street, Shizhu Tujia Autonomous County, Chongqing, China. It serves a population of approximately 90,000, placing it in the medium agglomeration category. The plant is an inland facility, situated away from the coast, and its operations are part of the municipal wastewater infrastructure for the region. The plant operates under China's national wastewater discharge standards, which require secondary treatment for urban wastewater treatment plants serving populations over 50,000. The designed capacity is reported as 1.00, indicating the plant's intended treatment volume. Compliance with these standards ensures that the treated effluent meets environmental protection requirements. The plant discharges into local water bodies that eventually drain into the Yangtze River basin, a major river system in China. The downstream environment supports diverse aquatic life and provides water for agricultural and industrial use. Effective treatment at this plant helps protect water quality in the region and contributes to the ecological health of the Yangtze River watershed.

The plant's treated effluent flows into local streams and rivers that are part of the Yangtze River basin, one of the largest and most ecologically significant river systems in Asia. The Yangtze River supports a wide variety of aquatic species, including the critically endangered Yangtze finless porpoise, and provides water for millions of people. Proper wastewater treatment is essential to reduce nutrient and pollutant loads that could harm downstream ecosystems and water quality.
