SKA STETTEN STORZINGEN Wastewater Treatment Plant, Storzingen, Germany

SKA STETTEN STORZINGEN is an advanced wastewater treatment plant located in Storzingen, a district of Stetten am kalten Markt in the Sigmaringen district of Baden-Württemberg, Germany. The plant serves a population of 2,676 and has a designed capacity of 4,600 m³/day, with an actual discharge volume of 768.49 m³/day. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. As a German facility, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires advanced treatment for sensitive areas. The plant's scale places it in the small agglomeration category, but its advanced treatment level reflects the environmental sensitivity of the region. The treated effluent is discharged into local watercourses that eventually drain into the Danube River basin. The Danube flows eastward through several countries before reaching the Black Sea. The plant's advanced treatment helps protect the water quality of the Danube and its tributaries, supporting aquatic ecosystems and downstream water uses.

The plant discharges into the Danube River basin, which flows through Central and Eastern Europe to the Black Sea. The region's karst geology and sensitive freshwater ecosystems require advanced nutrient removal to prevent eutrophication. The plant's location in the upper Danube catchment means its effluent quality directly affects downstream habitats, including floodplain forests and wetlands that support diverse aquatic life.
