Zhejiang Wastewater Treatment Plant, Haining, Zhejiang Province, China

The Zhejiang wastewater treatment plant is located in Haining City, Zhejiang Province, China, along the 524 National Highway in Huangwan Town. It serves a population of approximately 720,000, classifying it as a large agglomeration under Chinese wastewater management standards. The plant's designed capacity is 1. As a large-scale municipal facility in China, the plant is subject to national discharge standards under the Environmental Protection Law and the Water Pollution Prevention and Control Action Plan. Chinese regulations require secondary treatment as a baseline for urban wastewater, with more stringent standards in sensitive areas. The plant's proximity to the coast suggests it may need to meet higher effluent quality requirements to protect marine environments. The treated effluent from this plant likely discharges into local waterways that eventually flow into the East China Sea. The region's dense population and industrial activity place significant pressure on water resources, making effective wastewater treatment critical for protecting downstream aquatic ecosystems and coastal water quality.

The plant is located in the Yangtze River Delta, a densely populated and economically vital region in eastern China. Its treated effluent likely enters local rivers or canals that drain into Hangzhou Bay and ultimately the East China Sea. The coastal waters support diverse marine life and are important for fisheries, so nutrient and pollutant loads from wastewater must be carefully managed to prevent eutrophication and habitat degradation.
