Schonhausen Wastewater Treatment Plant, Schönhausen (Elbe), Saxony-Anhalt

The Schonhausen wastewater treatment plant is located in Schönhausen (Elbe), a town in the Elbe-Havel-Land district of Saxony-Anhalt, Germany. It serves a population of approximately 1,857 residents, reflecting a small agglomeration scale typical of rural communities in the region. 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. With a designed capacity of 5,300 m³/day and an actual discharge volume of 469.96 m³/day, the facility operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into the Elbe River, a major European waterway that flows through Germany into the North Sea. The plant's advanced treatment helps protect the Elbe's water quality and downstream ecosystems, including the Elbe estuary and the Wadden Sea, a critical habitat for migratory birds and marine life.

The plant discharges into the Elbe River, which flows northwest through Germany and empties into the North Sea near Cuxhaven. The Elbe basin supports diverse aquatic life and is an important migratory corridor for fish species such as Atlantic salmon and eel. Advanced treatment at this plant reduces nutrient loads, helping to prevent eutrophication in the sensitive coastal waters of the Wadden Sea.
