Overview
Yunnan wastewater treatment plant serves Jinghong City in Yunnan Province, China, with a population of 146,000. The plant discharges into local waterways within the Mekong River basin.
The Yunnan wastewater treatment plant is located in Jinghong City, Yunnan Province, China, serving a population of approximately 146,000. Situated in the tropical region of Xishuangbanna Dai Autonomous Prefecture, the plant is part of the municipal infrastructure for this urban area near the Mekong River. As a facility serving a medium-to-large agglomeration, the plant is expected to meet China's national discharge standards under the Environmental Protection Law and the Water Pollution Prevention and Control Action Plan. For plants of this scale, secondary treatment with nutrient removal is typical to protect downstream water quality. The plant's treated effluent likely discharges into tributaries of the Lancang River (upper Mekong), which flows through Southeast Asia. The downstream environment supports diverse aquatic life and is ecologically sensitive, with the Mekong basin being a major global biodiversity hotspot.
Environmental context
The plant discharges into the Lancang-Mekong River system, which flows from Yunnan through Myanmar, Laos, Thailand, Cambodia, and Vietnam before reaching the South China Sea. This watershed supports critical fisheries and biodiversity, including the Mekong giant catfish and Irrawaddy dolphin. The region's tropical climate and seasonal monsoon influence river flow and pollutant dilution.
