SKA SASBACH Wastewater Treatment Plant, Sasbach am Kaiserstuhl, Germany

SKA SASBACH is a municipal wastewater treatment plant located in Sasbach am Kaiserstuhl, Baden-Württemberg, Germany. The plant serves a population of approximately 4,700 people and is situated near the Rhine River, which forms the border with France. As a facility in the Upper Rhine region, it plays a key role in protecting local water quality. The plant operates with advanced treatment technology, which goes beyond the standard secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 8,000 m³/day and a current discharge volume of 661.4 m³/day, the plant has ample capacity to handle current loads. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to reduce eutrophication risks in sensitive receiving waters. The treated effluent is discharged into the Rhine River, which flows northward through Germany and the Netherlands before reaching the North Sea. The Rhine is a major European waterway and ecologically significant corridor. By employing advanced treatment, SKA SASBACH helps maintain the water quality of the Rhine, supporting aquatic life and downstream uses such as drinking water production and recreation.

The plant discharges into the Rhine River, a major transboundary watercourse that flows through Germany and the Netherlands to the North Sea. The Upper Rhine region is ecologically sensitive, supporting diverse aquatic habitats and migratory fish species. Advanced treatment at this plant helps reduce nutrient loads, mitigating eutrophication risks in the Rhine and its downstream delta.
