SKA Herbolzheim Wastewater Treatment Plant, Rheinhausen, Baden-Württemberg

SKA Herbolzheim is a municipal wastewater treatment plant located in Rheinhausen, within the Emmendingen district of Baden-Württemberg, Germany. The plant serves a population of approximately 8,650 people, classifying it as a small to medium agglomeration under EU regulations. The plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. German federal and state regulations further enforce strict effluent standards to protect water quality. The treated effluent is discharged into local water bodies that ultimately drain into the Rhine River basin. The Rhine is a major European waterway supporting diverse aquatic ecosystems and providing drinking water for millions downstream. The plant's operation helps maintain the ecological health of this important river system.

The plant discharges into local streams that flow into the Rhine River, one of Europe's most significant waterways. The Rhine basin supports a wide range of aquatic life, including migratory fish species such as salmon and eel. Downstream, the river flows through the Upper Rhine Valley and eventually into the North Sea, making nutrient and pollutant control critical for both local and marine environments.
