SKA Rheinau Freistett Wastewater Treatment Plant, Freistett, Germany

SKA Rheinau Freistett is a municipal wastewater treatment plant located in Freistett, a district of Rheinau in the Ortenaukreis district of Baden-Württemberg, Germany. The plant serves a population of around 10,400, placing it in the category of a small to medium agglomeration under EU classification. As a German facility, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant's treatment processes are designed to meet national standards under the German Water Resources Act (Wasserhaushaltsgesetz), ensuring compliance with effluent quality requirements. The treated wastewater 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. The plant plays a key role in protecting the Rhine's water quality by reducing nutrient and pollutant loads.

The plant discharges into the Rhine River basin, which flows through Germany and the Netherlands into the North Sea. The Rhine supports a rich diversity of fish species, including salmon and eel, and is an important migratory corridor. The plant's nutrient removal helps prevent eutrophication in downstream waters, including the North Sea.
