Crivitz Wastewater Treatment Plant | Mecklenburg-Vorpommern, Germany

The Crivitz wastewater treatment plant is located in the town of Crivitz, in the state of Mecklenburg-Vorpommern, Germany. It serves a population of approximately 5,158 people, classifying it as a small to medium agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). The plant is situated inland, more than 10 km from the coast, and its operations are part of the regional water management infrastructure. The plant employs advanced treatment processes, which go beyond the secondary treatment standard 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 6,000 cubic meters per day and reports an annual discharge volume of 506.85 thousand cubic meters, indicating it operates below its maximum capacity. The treated effluent is discharged into local watercourses that eventually drain into the Baltic Sea via the Warnow or Elde river systems. The region's watershed supports diverse aquatic life and is part of the larger Baltic Sea catchment, which is ecologically sensitive to nutrient pollution. Advanced treatment at Crivitz helps reduce the nutrient load entering the Baltic, contributing to the goals of the Helsinki Convention and the EU's Marine Strategy Framework Directive.

The Crivitz plant discharges into local streams that flow into the Warnow or Elde rivers, both of which drain into the Baltic Sea. The Baltic Sea is a semi-enclosed brackish sea with limited water exchange, making it highly sensitive to eutrophication from nutrient inputs. Advanced treatment at Crivitz helps mitigate this risk by removing nitrogen and phosphorus, supporting the ecological health of downstream waters and the Baltic Sea ecosystem.
