Zhejiang Wastewater Treatment Plant, Pujiang County, Jinhua, Zhejiang

The Zhejiang wastewater treatment plant is located in Pujiang County, Jinhua City, Zhejiang Province, China. It serves an estimated population of 140,000, placing it in the medium-to-large agglomeration category for Chinese wastewater infrastructure. As a plant of this scale in China, it is expected to meet national discharge standards under the Environmental Protection Law and the Water Pollution Prevention and Control Action Plan. Chinese regulations typically require secondary or advanced treatment for plants serving over 100,000 people, with nutrient removal in sensitive watersheds. The plant's treated effluent likely discharges into local rivers that feed into the Qiantang River basin, which flows into Hangzhou Bay and the East China Sea. This watershed supports diverse aquatic life and provides water for agricultural and industrial use downstream.

The plant discharges into the Qiantang River basin, which flows through Zhejiang Province into Hangzhou Bay and the East China Sea. This watershed supports important fisheries and provides water for irrigation and industry.
