SKA Schonau Ellwangen Wastewater Treatment Plant, Ellwangen (Jagst), Germany

SKA Schonau Ellwangen is a municipal wastewater treatment plant located in the Schönau district of Ellwangen (Jagst), in the Ostalbkreis region of Baden-Württemberg, Germany. The plant serves a population of approximately 23,800 people, placing it in the medium agglomeration category under the EU Urban Waste Water Treatment Directive (UWWTD). As a German wastewater facility, SKA Schonau Ellwangen operates under the national implementation of the EU UWWTD (91/271/EEC), which requires secondary biological treatment for agglomerations of this size. The plant's treatment processes are designed to meet stringent German effluent standards, which often include nutrient removal to protect sensitive water bodies. The treated effluent from SKA Schonau Ellwangen is discharged into the local watershed, which ultimately drains into the Jagst River, a tributary of the Neckar River. The Neckar flows into the Rhine River, which reaches the North Sea. The plant plays a key role in maintaining water quality in the Jagst catchment, supporting aquatic ecosystems and downstream water uses.

The plant discharges into the Jagst River, a tributary of the Neckar River, which flows into the Rhine and eventually the North Sea. The Jagst catchment supports diverse aquatic life, including fish species such as brown trout and grayling. The region's agricultural land use requires careful nutrient management to prevent eutrophication in downstream waters.
