Overview
Hunan wastewater treatment plant serves 168,700 people in Xinhua County, Loudi City, Hunan Province, China. The facility discharges treated effluent into local waterways within the Yangtze River basin.
The Hunan wastewater treatment plant is located in Shangmei Subdistrict, Xinhua County, Loudi City, Hunan Province, China. It serves a population of 168,700, classifying it as a medium-to-large agglomeration under Chinese wastewater management standards. The plant is situated inland, approximately 50 km from the coast, and its operations are part of the municipal infrastructure for the region. China's wastewater treatment regulations, governed by the Water Pollution Prevention and Control Law, require secondary treatment for urban plants of this scale. The population served suggests a capacity in the range of 30,000 to 50,000 cubic meters per day. The treated effluent is discharged into local rivers that flow into the Zi River, a tributary of the Xiang River, which ultimately drains into Dongting Lake and then the Yangtze River. This watershed supports diverse aquatic life and provides water for agriculture and industry downstream. The plant plays a critical role in protecting water quality in the densely populated Hunan region.
Environmental context
The plant discharges into local waterways within the Zi River basin, which flows into the Xiang River and then Dongting Lake, a major freshwater lake in the Yangtze River floodplain. Dongting Lake is ecologically significant as a habitat for migratory birds and fish species, and it helps regulate floodwaters. Downstream, the Yangtze River supports extensive biodiversity and provides water for millions of people. The plant's effluent quality directly impacts these downstream ecosystems, making proper treatment essential.
