Yunnan Wastewater Treatment Plant, Jinzhong Street, Yunnan Province

Yunnan wastewater treatment plant is located in Jinzhong Street, Huize County, Qujing City, Yunnan Province, China. The facility serves a population of approximately 40,300, placing it in the medium agglomeration category under Chinese wastewater regulations. As an inland plant, it plays a key role in managing municipal wastewater in this region of Yunnan. Under China's national wastewater standards, plants of this scale are typically required to meet Class 1A or 1B discharge limits, which mandate secondary treatment with nutrient removal. Regulatory expectations for similar facilities include biological treatment and disinfection to protect receiving waters. The treated effluent likely discharges into a local watercourse that flows into the larger Yangtze River basin, as Yunnan is part of the upper Yangtze watershed. The plant's operation helps safeguard downstream aquatic ecosystems and supports water quality in the region's rivers, which are important for agriculture and biodiversity.

The plant discharges into a local tributary of the Yangtze River system, which flows through Yunnan and eventually reaches the East China Sea. The watershed supports diverse aquatic life and is ecologically sensitive due to its role in regional water supply and habitat connectivity. Protecting this river network is vital for maintaining water quality and ecosystem health in the upper Yangtze basin.
