Overview
Yunnan wastewater treatment plant serves Xishan District, Kunming, Yunnan, China, with a population of 589,000. It operates under China's national wastewater standards.
The Yunnan wastewater treatment plant is located in Xishan District, Kunming, Yunnan Province, China. It serves a population of 589,000, classifying it as a large-scale municipal facility. The plant is situated in the urban area of Kunming, near the Dianchi Lake basin, a region with significant environmental sensitivity. As a large agglomeration in China, the plant is expected to meet the discharge standards set by the national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). This standard requires advanced treatment (Class 1A or 1B) for plants in sensitive areas like Dianchi Lake, which is a key water body in Yunnan. Regulatory compliance is critical for protecting downstream waters. The plant's treated effluent likely discharges into the Dianchi Lake watershed, which eventually drains into the Yangtze River system via the Pudu River. Dianchi Lake is a large freshwater lake that supports diverse aquatic life and is a vital resource for irrigation, industry, and recreation in the region. Protecting this watershed from nutrient pollution is a priority for local environmental authorities.
Environmental context
The plant is located in the Dianchi Lake basin, a major watershed in Yunnan Province. Dianchi Lake is the largest lake in Yunnan and drains via the Pudu River into the Yangtze River system, ultimately reaching the East China Sea. The lake is ecologically sensitive due to historical eutrophication issues, and the plant's discharge must meet strict nutrient removal standards to prevent algal blooms and protect aquatic biodiversity.
