KA Suderburg Wastewater Treatment Plant - Suderburg, Niedersachsen

KA Suderburg (plant code 3604052080) is a municipal wastewater treatment facility located in Suderburg, a town in the Samtgemeinde Suderburg, Uelzen district, Niedersachsen, Germany. The plant serves a population of approximately 4,525 and has a designed capacity of 7,400 cubic meters per day, with an average discharge volume of 971.69 m³/day. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive water bodies. As a German facility, it operates under the national Wasserhaushaltsgesetz (WHG) and Abwasserverordnung (AbwV), which set strict effluent standards. The treated effluent is discharged into local watercourses that drain into the Ilmenau River, a tributary of the Elbe River, which ultimately flows into the North Sea. The plant plays a key role in maintaining water quality in the region, supporting aquatic ecosystems and downstream uses such as drinking water abstraction and recreation.

The plant discharges into the Ilmenau River basin, which flows into the Elbe River and then the North Sea. The Elbe estuary is an ecologically sensitive area supporting diverse aquatic life, including migratory fish species. Advanced treatment at this plant helps reduce nutrient loads that could contribute to eutrophication in the North Sea.
