Karstadt Wastewater Treatment Plant, Karstädt, Brandenburg, Germany

The Karstadt wastewater treatment plant is located in Karstädt, a town in the Prignitz district of Brandenburg, Germany. The facility serves a population of approximately 5,428 and is designed to handle up to 10,000 cubic meters of wastewater per day, with an average daily discharge of 747.79 cubic meters. As an advanced treatment plant, it goes beyond secondary treatment to remove nutrients such as nitrogen and phosphorus, which is typical for facilities in sensitive catchment areas. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), Germany requires advanced treatment for agglomerations of this size when discharging into sensitive areas, ensuring high effluent quality. The treated effluent is discharged into local watercourses that ultimately drain into the Elbe River basin. The Elbe flows through northern Germany into the North Sea, supporting diverse aquatic ecosystems and providing drinking water for millions. The plant's advanced treatment helps protect downstream water quality and ecological health.

The plant discharges into the Elbe River basin, which flows through Brandenburg and into the North Sea. The Elbe supports diverse aquatic life, including migratory fish species such as Atlantic salmon and sea trout. Advanced treatment at this plant reduces nutrient loading, helping to prevent eutrophication in downstream waters and the North Sea.
