Overview
Sichuan wastewater treatment plant serves approximately 39,900 people in Dongqu, Panzhihua, Sichuan, China. The facility operates under China's national wastewater standards for urban agglomerations of this scale.
The Sichuan wastewater treatment plant is located in Dongqu, a district of Panzhihua city in Sichuan Province, China. The facility serves an estimated population of 39,900, placing it in the medium agglomeration category under Chinese wastewater regulations. The plant is situated near the Hua'nan Bridge in Dadukou Subdistrict, within the urban area of Panzhihua. China's wastewater treatment standards require secondary treatment for urban plants serving populations above 10,000, with more stringent nutrient removal in sensitive watersheds. The plant's designed capacity and current operational status are not disclosed in public records. The treated effluent from this plant likely discharges into a tributary of the Yangtze River basin, as Panzhihua lies along the Jinsha River, a major upstream branch of the Yangtze. The downstream environment includes the Jinsha River valley and eventually the Yangtze River, which supports diverse aquatic ecosystems and provides water for millions of people. Effective treatment at this plant helps protect water quality in this ecologically significant river system.
Environmental context
The plant discharges into the Jinsha River, a major tributary of the upper Yangtze River, which flows through the mountainous region of Sichuan. The downstream Yangtze River supports diverse aquatic life, including endemic fish species, and provides drinking water for large populations. The watershed is ecologically sensitive due to its role in maintaining river health and biodiversity in southwestern China.
