SKA Wallhausen Wallhausen Wastewater Treatment Plant, Wallhausen, Baden-Württemberg

SKA Wallhausen Wallhausen is a municipal wastewater treatment plant located in Wallhausen, a town in the Schwäbisch Hall district of Baden-Württemberg, Germany. The plant serves a population of approximately 3,400 residents, placing it in the small agglomeration category under the EU Urban Waste Water Treatment Directive (UWWTD). The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU UWWTD for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive water bodies. The plant has a designed capacity of 2,500 cubic meters per day and currently discharges an average of 745.59 cubic meters per day, indicating operational headroom. The treated effluent is discharged into local waterways that ultimately drain into the Jagst River, a tributary of the Neckar, which flows into the Rhine River and then the North Sea. The plant's advanced treatment helps maintain water quality in the sensitive Rhine basin, supporting aquatic life and downstream ecosystems.

The plant discharges into the local watershed that feeds the Jagst River, a tributary of the Neckar River, which is part of the larger Rhine basin. The Rhine basin is a major European waterway that supports diverse aquatic ecosystems and provides drinking water for millions. Advanced treatment at this plant helps reduce nutrient loads, protecting downstream water bodies from eutrophication and maintaining ecological balance in the region.
