Overview
Yunnan wastewater treatment plant serves Eshan Yi Autonomous County in Yunnan, China, with a population equivalent of 100,000. The facility is located inland, discharging into local waterways within the broader Yangtze River basin.
The Yunnan wastewater treatment plant is located in Shuangjiang Community, Shuangjiang Street, Eshan Yi Autonomous County, Yuxi City, Yunnan Province, China. It serves a population equivalent of 100,000, classifying it as a medium-to-large agglomeration under typical Chinese municipal wastewater standards. As a plant in China, it operates under national regulations including the Environmental Protection Law and the Water Pollution Prevention and Control Law. For facilities serving around 100,000 people, secondary treatment with nutrient removal is generally required to meet discharge standards, especially in sensitive watersheds. Regulatory frameworks mandate appropriate treatment levels for this scale. The plant's treated effluent likely discharges into local rivers or streams that eventually flow into the Yangtze River basin, a major water system supporting diverse aquatic life and providing water for agriculture, industry, and domestic use downstream. Proper treatment is critical to protect water quality in this ecologically and economically vital region.
Environmental context
The plant is situated inland in Yunnan Province, a region characterized by mountainous terrain and numerous rivers. Its discharge likely enters the local water network, eventually reaching the Yangtze River basin. The Yangtze River supports a wide range of aquatic species, including endangered fish, and provides water for millions of people. Effective wastewater treatment helps prevent eutrophication and contamination in this sensitive watershed.
