Stendal Wastewater Treatment Plant, Stendal, Sachsen-Anhalt, Germany

The Stendal wastewater treatment plant is located in the city of Stendal, in the state of Sachsen-Anhalt, Germany. It serves a population of approximately 92,541 people, classifying it as a medium-to-large agglomeration under EU regulations. As a German facility, the plant operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations with a population equivalent (PE) between 10,000 and 150,000. For larger agglomerations, more stringent treatment may be required if the receiving water body is designated as sensitive. The plant discharges treated wastewater into local water bodies that ultimately drain into the Elbe River basin, which flows into the North Sea. The region's aquatic ecosystems benefit from the treatment processes that reduce nutrient loads and protect downstream habitats.

The Stendal plant discharges into the Elbe River basin, which flows through northern Germany into the North Sea. The Elbe estuary supports diverse aquatic life and is an important migratory corridor for fish species. Nutrient removal from wastewater helps mitigate eutrophication risks in the downstream coastal environment.
