Overview
Gansu wastewater treatment plant serves Wuwei City in Gansu Province, China, with a population of 283,000. It operates under China's national wastewater regulations.
The Gansu wastewater treatment plant is located in Wuwei City, Gansu Province, China, serving a population of approximately 283,000. The facility is situated in the Liangzhou District, near the Xinxian Bridge, and plays a key role in managing municipal wastewater for this inland urban area. As a large agglomeration serving over 150,000 people, the plant is expected to meet China's national discharge standards, which require secondary treatment as a minimum. China's Water Pollution Prevention and Control Action Plan mandates stringent effluent limits for plants in sensitive watersheds, and facilities of this scale typically incorporate biological treatment processes to comply with these regulations. The treated effluent from the plant is discharged into local water bodies that ultimately drain into the Yellow River basin, a major river system in northern China. The plant's operations help protect downstream water quality and support the ecological health of the region, which faces challenges from agricultural runoff and industrial activities.
Environmental context
The plant discharges into the Shiyang River system, a tributary of the Yellow River basin. The Shiyang River flows through arid and semi-arid regions of Gansu, supporting irrigation and local ecosystems. Downstream, the river contributes to the Yellow River, which is ecologically significant for its role in sustaining agriculture, fisheries, and biodiversity in northern China. The plant's treatment performance is critical to preventing eutrophication and protecting aquatic life in this water-stressed region.
