Overview
Yunnan wastewater treatment plant serves Shiping County in Yunnan, China, with a population equivalent of 58,100. It operates under China's national wastewater standards for medium-sized agglomerations.
The Yunnan wastewater treatment plant is located in Shiping County, part of the Honghe Hani and Yi Autonomous Prefecture in Yunnan Province, China. It serves a population of approximately 58,100, classifying it as a medium-sized municipal facility within the region's wastewater infrastructure. The plant operates under China's national discharge standards, which require secondary treatment for urban wastewater. For agglomerations of this scale, compliance with the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002) is typical, ensuring treated effluent meets environmental protection requirements. The plant's treated effluent likely discharges into a local watercourse within the Honghe River basin, which flows southward into Vietnam as the Red River. This river system supports diverse aquatic life and provides water for agriculture and communities downstream. Proper treatment is essential to protect water quality in this transboundary watershed.
Environmental context
The plant is situated in the Honghe River basin, a major tributary of the Red River that flows through Yunnan into Vietnam and ultimately into the South China Sea. The region's subtropical climate and mountainous terrain make the watershed ecologically sensitive, supporting diverse freshwater species and providing irrigation for rice and other crops. Effective wastewater treatment helps prevent nutrient pollution and maintain the ecological balance of this important transboundary river system.
