Overview
Yunnan wastewater treatment plant serves Gejiu City in Yunnan Province, China, with a population equivalent of 200,000. The facility operates under China's national wastewater discharge standards.
The Yunnan wastewater treatment plant is located in Gejiu City, within the Honghe Hani and Yi Autonomous Prefecture of Yunnan Province, China. Serving a population equivalent of 200,000, it is a medium-to-large municipal facility in the urban area of Gejiu. Under China's national wastewater discharge standards (GB 18918-2002), plants of this scale are typically required to achieve at least secondary treatment, with stricter limits for sensitive water bodies. The facility's treatment process and capacity details are not publicly available, but it operates within the regulatory framework of China's Water Pollution Prevention and Control Law. The plant discharges treated effluent into local waterways that ultimately drain into the Red River system, which flows through Yunnan and into Vietnam before reaching the South China Sea. The receiving water bodies support aquatic ecosystems and are used for agricultural irrigation downstream.
Environmental context
The plant's treated effluent enters the local drainage network within the Red River basin, which flows southeast through Yunnan and into northern Vietnam. The Red River delta is an ecologically important region supporting diverse aquatic life and agricultural activity. Downstream water quality is influenced by upstream industrial and municipal discharges, making treatment standards critical for ecosystem health.
