Overview
Shanghai wastewater treatment plant serves 77,000 people in Fengxian District, China. The facility operates under national wastewater standards for medium-sized agglomerations.
The Shanghai wastewater treatment plant is located in Fengxian District, a suburban area of Shanghai, China. It serves a population of approximately 77,000 people, classifying it as a medium-sized agglomeration under Chinese wastewater management frameworks. The plant's designed capacity is 1. In China, wastewater treatment plants of this scale are typically regulated under national standards such as the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). These standards mandate secondary treatment as a baseline, with more stringent requirements for plants discharging into sensitive water bodies. It is expected to meet at least secondary treatment standards to comply with national regulations. The plant discharges treated effluent into local waterways that ultimately drain into the East China Sea. The receiving water body is part of the Yangtze River Delta watershed, a densely populated and economically vital region. Proper treatment is essential to protect downstream aquatic ecosystems and coastal water quality, supporting fisheries and biodiversity in the East China Sea.
Environmental context
The plant's treated effluent flows into local rivers within the Yangtze River Delta, eventually reaching the East China Sea. This coastal region supports diverse marine life and is an important fishing ground. The watershed is heavily influenced by urban and industrial runoff, making effective wastewater treatment critical to prevent eutrophication and protect downstream habitats.
