Overview
Zhejiang wastewater treatment plant serves 210,000 people in Zhenhai District, Ningbo, Zhejiang Province, China. The facility discharges into the local water system within 50 km of the coast.
The Zhejiang wastewater treatment plant is located in Zhenhai District, Ningbo, Zhejiang Province, China, serving a population of 210,000. The facility is situated in a densely populated urban area near the coast of the East China Sea. As a municipal treatment plant, it plays a key role in managing wastewater from residential and industrial sources in the region. Plants of this scale in China typically employ secondary or advanced treatment to meet national discharge standards. The designed capacity is 1.00 (likely in million cubic meters per year or similar unit), indicating a substantial infrastructure investment. Chinese regulations require compliance with the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), which sets limits on key pollutants. The plant's treated effluent ultimately reaches the East China Sea via local rivers and coastal waters. The receiving environment supports diverse marine life and is important for local fisheries. Proper treatment helps protect coastal water quality and reduce eutrophication risks in the sensitive marine ecosystem.
Environmental context
The plant discharges into the local river network that flows into the East China Sea near Ningbo. This coastal region supports important marine habitats and fisheries.
