Klostermansfeld Wastewater Treatment Plant | Sachsen-Anhalt, Germany

The Klostermansfeld wastewater treatment plant is located in the town of Klostermansfeld, in the Mansfeld-Südharz district of Sachsen-Anhalt, Germany. It serves a population of approximately 3,073, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). The plant is situated inland, far from coastal waters. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU UWWTD for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive water bodies. The plant has a designed capacity of 4,250 m³/day and currently discharges 203.86 thousand m³ of treated wastewater annually, indicating significant spare capacity. The treated effluent is discharged into local watercourses that eventually drain into the Saale River, a major tributary of the Elbe River, which flows into the North Sea. The plant's advanced treatment helps protect the aquatic ecosystems of the Saale and Elbe basins from eutrophication and other pollution impacts.

The plant discharges into local streams that feed into the Saale River, part of the Elbe River basin. The Elbe flows through Germany and the Czech Republic before reaching the North Sea. The region's water bodies support diverse aquatic life and are important for migratory fish species. Advanced treatment at this plant helps reduce nutrient loads, protecting downstream ecosystems from algal blooms and oxygen depletion.
