Overview
Yunnan wastewater treatment plant serves 108,700 people in 乐白道街道, Kaiyuan, Yunnan, China. It operates under China's national wastewater standards for medium-sized agglomerations.
Yunnan wastewater treatment plant is located in 乐白道街道 (Lebaidou Street), Kaiyuan City, within the Honghe Hani and Yi Autonomous Prefecture of Yunnan Province, China. The facility serves a population of 108,700, classifying it as a medium-to-large agglomeration under Chinese wastewater management frameworks. As a plant serving over 100,000 people, it is expected to meet secondary treatment standards under China's Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), with potential nutrient removal requirements in sensitive watersheds. Regulatory compliance is enforced by provincial environmental authorities. The 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 ecosystems and provides water for agriculture and communities downstream. The plant plays a key role in protecting water quality in this transboundary basin.
Environmental context
The plant is situated inland in Yunnan Province, within the Honghe (Red River) basin. The Red River originates in Yunnan and flows through Vietnam into the Gulf of Tonkin, South China Sea. The watershed supports important fisheries and agricultural irrigation. Effective wastewater treatment is critical to prevent nutrient pollution and protect downstream ecosystems, including wetlands and estuaries in Vietnam.
Frequently asked questions
The plant is located in 乐白道街道 (Lebaidou Street), Kaiyuan City, Honghe Hani and Yi Autonomous Prefecture, Yunnan Province, China.
The plant serves approximately 108,700 people, making it a medium-to-large agglomeration under Chinese wastewater classification.
The plant discharges into the Honghe (Red River) basin, which flows through Yunnan and into Vietnam, eventually reaching the Gulf of Tonkin. It helps protect water quality in this transboundary river system.
The plant operates under China's GB 18918-2002 discharge standard, which mandates secondary treatment for municipal plants. For agglomerations over 100,000 people, enhanced nutrient removal may be required in sensitive areas.
Plants of this scale typically employ secondary treatment processes such as activated sludge or sequencing batch reactors, often with biological nutrient removal to meet Class 1A or 1B discharge standards.
