Overview
Yunnan wastewater treatment plant serves Simao District, Pu'er City, Yunnan Province, China, with a population of 60,700. The facility operates under China's national wastewater standards.
The Yunnan wastewater treatment plant is located in Simao District, Pu'er City, Yunnan Province, China. It serves a population of approximately 60,700 people, placing it in the medium agglomeration category for Chinese municipal wastewater infrastructure. The plant is situated in a mountainous region of southwestern China, characterized by a subtropical climate and significant seasonal rainfall. As a municipal facility in China, the plant is subject to the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets effluent limits based on the receiving water's sensitivity. For plants serving populations over 50,000, secondary treatment with nutrient removal is typically required, especially when discharging into sensitive water bodies. The plant's operational details are managed by local authorities in Pu'er City. The treated effluent from the plant is discharged into local waterways that eventually flow into the Mekong River basin, one of Southeast Asia's major river systems. This downstream connection underscores the plant's role in protecting water quality for both local ecosystems and transboundary water resources. The surrounding area supports diverse aquatic life and agricultural activities dependent on clean water.
Environmental context
The plant discharges into tributaries of the Mekong River, which flows through China, Myanmar, Laos, Thailand, Cambodia, and Vietnam before reaching the South China Sea. The local watershed in Yunnan is ecologically sensitive, supporting diverse freshwater species and providing water for agriculture. Downstream ecosystems rely on adequate treatment to prevent nutrient pollution and maintain biodiversity in this internationally important river system.
