Overview
Yunnan wastewater treatment plant serves 77,000 people in Chengjiang, Yuxi, Yunnan, China. It operates under China's national wastewater standards for urban agglomerations.
Yunnan wastewater treatment plant is located in Chengjiang, a county-level city under Yuxi in Yunnan Province, China. The facility serves a population of approximately 77,000, placing it in the medium-sized agglomeration category for Chinese municipal wastewater infrastructure. China's wastewater treatment regulations, including the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002), require secondary treatment as a baseline for urban plants. For agglomerations serving over 50,000 people, advanced treatment may be mandated in sensitive watersheds to meet stricter effluent limits. The plant's treated effluent likely discharges into local water bodies that drain into the broader Yangtze River basin or the Pearl River system, depending on the exact watershed. Yunnan's karst topography and rich biodiversity make proper wastewater management critical for protecting downstream aquatic ecosystems and groundwater resources.
Environmental context
The plant is situated in Yunnan Province, a region known for its karst landscapes and numerous lakes, including Fuxian Lake near Chengjiang. Treated wastewater from the plant likely flows into local streams that eventually reach the Nanpan River, a tributary of the Pearl River, which drains into the South China Sea. The area supports diverse aquatic life and is ecologically sensitive due to its unique geology and high endemism.
