Bad Kosen Wastewater Treatment Plant | Bad Kösen, Sachsen-Anhalt, Germany

The Bad Kosen wastewater treatment plant is located in the town of Bad Kösen, within the Burgenlandkreis district of Sachsen-Anhalt, Germany. It serves a population of approximately 5,918 residents, classifying it as a small to medium agglomeration under German and EU regulations. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 6,000 cubic meters per day and an average discharge volume of 873.74 cubic meters per day, the facility operates well within its capacity, ensuring effective treatment of municipal wastewater. The treated effluent is discharged into the local watershed, which ultimately drains into the Saale River, a major tributary of the Elbe River. The Elbe flows into the North Sea, making the plant's advanced treatment important for protecting downstream water quality and aquatic ecosystems in the Saale and Elbe basins.

The plant discharges into the Saale River, which flows northward through Saxony-Anhalt and joins the Elbe River near Barby. The Elbe then continues to the North Sea, passing through ecologically sensitive areas such as the Elbe Estuary, which supports diverse aquatic life and migratory fish species. Advanced treatment at Bad Kosen helps reduce nutrient loads and pollutants, contributing to the ecological health of these downstream waters.
