Overview
Yunnan wastewater treatment plant serves Yuxi City, Yunnan Province, China, with a population equivalent of 80,000. It operates under China's national wastewater discharge standards.
The Yunnan wastewater treatment plant is located in Huaning County, Yuxi City, in the mountainous Yunnan Province of southwestern China. The facility serves a population equivalent of approximately 80,000, classifying it as a medium-sized municipal treatment plant within the region. Under China's national wastewater discharge standards (GB 18918-2002), treatment plants of this scale are typically required to achieve at least secondary treatment to meet pollutant limits for discharge into surface waters. The regulatory framework ensures compliance with environmental protection requirements. The treated effluent from the plant is likely discharged into a local river within the Pearl River basin or a tributary of the Red River system, which ultimately flows into the South China Sea. The surrounding watershed supports diverse aquatic life and is important for regional water resources and agriculture.
Environmental context
The plant is situated in the Yunnan-Guizhou Plateau, a region characterized by karst topography and numerous rivers.
