Guizhou Wastewater Treatment Plant, Liupanshui, Guizhou Province, China

The Guizhou wastewater treatment plant is located in Liupanshui City, Guizhou Province, China, along Zangke Avenue in Liuzhi Special District. It serves a population of approximately 36,500 people, making it a medium-sized agglomeration under Chinese wastewater management standards. The plant is part of the municipal infrastructure for Liupanshui, a city in the mountainous region of southwestern China. As a facility serving over 10,000 people, the plant is expected to comply with China's national discharge standards, which require secondary treatment as a minimum. Chinese regulations for urban wastewater treatment plants mandate effective biological treatment to protect water quality. The plant operates under the framework of China's Water Pollution Prevention and Control Law, which sets effluent limits for pollutants such as COD, BOD, and ammonia nitrogen. The plant discharges treated wastewater into local rivers that flow into the broader Yangtze River basin, eventually reaching the East China Sea. The surrounding region features karst landscapes and diverse aquatic ecosystems. Proper treatment helps protect downstream water bodies used for drinking water, agriculture, and fisheries, supporting both human communities and biodiversity in Guizhou's ecologically sensitive areas.

The plant discharges into local tributaries of the Yangtze River basin, which ultimately drains into the East China Sea. The region's karst topography creates interconnected groundwater systems, making water quality management critical for protecting both surface and subsurface aquatic habitats. The downstream environment supports diverse freshwater species and provides water resources for communities in Guizhou Province.
