Overview
Zhejiang wastewater treatment plant serves 42,000 people in Chun'an County, Hangzhou, Zhejiang, China. It discharges into the local watershed near Qiandao Lake.
The Zhejiang wastewater treatment plant is located in Chun'an County, within the city of Hangzhou, Zhejiang Province, China. It serves a population of 42,000, placing it in the medium-agglomeration category under Chinese wastewater regulations. China's wastewater treatment standards require secondary treatment for urban plants, with more stringent nutrient removal in sensitive lake basins. The plant's location near Qiandao Lake, a major reservoir and drinking water source, likely necessitates advanced treatment to protect water quality. The plant discharges into the Qiandao Lake watershed, which drains into the Xin'an River and eventually the Fuchun River before reaching Hangzhou Bay and the East China Sea. The lake supports diverse aquatic life and is an important ecological and recreational resource.
Environmental context
The plant discharges into the Qiandao Lake watershed, a large reservoir in Zhejiang Province that flows into the Xin'an River, then the Fuchun River, and ultimately Hangzhou Bay and the East China Sea. The lake is ecologically sensitive, supporting diverse aquatic species and serving as a critical drinking water source for downstream communities.
