The Hubei wastewater treatment plant serves 155,000 people in San'guandian Subdistrict, Danjiangkou, Shiyan, Hubei, China. It discharges into the Han River, a tributary of the Yangtze River.
The Hubei wastewater treatment plant is located in San'guandian Subdistrict, Danjiangkou City, Shiyan, Hubei Province, China. It serves a population of 155,000, classifying it as a large agglomeration under Chinese wastewater regulations. The plant is situated along Hanjiang Avenue, near the Han River. As a large-scale municipal facility, the plant is expected to provide at least secondary treatment in accordance with China's national discharge standards (GB 18918-2002). Facilities of this size typically employ biological treatment methods such as activated sludge or oxidation ditch to meet effluent quality requirements. The treated wastewater is discharged into the Han River, a major tributary of the Yangtze River. The Han River flows through Hubei and into the Yangtze at Wuhan, supporting diverse aquatic life and providing water for agriculture and industry. The plant plays a key role in protecting the Han River's water quality and the downstream Yangtze ecosystem.
Environmental context
The plant discharges into the Han River, which flows southeast through Hubei Province before joining the Yangtze River at Wuhan. The Han River basin supports important fisheries and provides drinking water for millions. Downstream, the Yangtze River is one of the world's most biodiverse waterways, home to species such as the Yangtze finless porpoise and Chinese sturgeon. Protecting water quality in the Han River is critical for maintaining the ecological health of the Yangtze River system.
