Zhejiang Wastewater Treatment Plant, Kaihua County, Zhejiang Province, China

The Zhejiang wastewater treatment plant is situated in Kaihua County, part of Zhejiang Province in eastern China. It serves a population of approximately 51,000 people, classifying it as a medium-sized agglomeration under Chinese wastewater management standards. The plant is located in the inland region of Zhejiang, away from coastal areas, and plays a key role in treating municipal wastewater from the local community. As a facility in China, the plant operates under the national wastewater discharge standards, which are governed by the Ministry of Ecology and Environment. For a plant serving around 51,000 people, secondary treatment is typically required to meet the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918-2002). It is expected to comply with these regulations to protect local water bodies. The treated effluent from the plant is discharged into local rivers that eventually flow into the Qiantang River basin, which drains into the East China Sea. The plant's operation is crucial for maintaining water quality in the region, supporting aquatic life, and preventing pollution in downstream ecosystems. Its inland location reduces direct marine impact but still influences the broader watershed.

The plant discharges into local waterways that are part of the Qiantang River basin, which ultimately flows into the East China Sea. This watershed supports diverse aquatic habitats and is important for regional biodiversity. The plant's effluent management helps protect downstream water quality, particularly in ecologically sensitive areas that rely on clean water for fisheries and agriculture.
