SKA Schrozberg Riedbach Wastewater Treatment Plant, Schrozberg, Germany

SKA Schrozberg Riedbach is a municipal wastewater treatment plant located in the Riedbach district of Schrozberg, in the Landkreis Schwäbisch Hall, Baden-Württemberg, Germany. The plant serves a population of approximately 2,450 people, classifying it as a small agglomeration under German and EU regulations. The plant provides secondary treatment, which is the standard biological treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. The designed capacity is 1,050 m³/day, with an actual discharge volume of 344.19 m³/day, indicating operational headroom. The treated effluent is discharged into local watercourses that ultimately drain into the Jagst River, a tributary of the Neckar, which flows into the Rhine and then the North Sea. The plant plays a key role in protecting the local watershed and downstream aquatic ecosystems from nutrient pollution.

The plant discharges into small streams in the Riedbach area, which feed into the Jagst River system. The Jagst flows through the Hohenlohe region before joining the Neckar, a major Rhine tributary. The watershed supports diverse aquatic life, including fish species such as brown trout and grayling. The plant's secondary treatment helps reduce organic load and nutrient inputs, protecting downstream water quality in this ecologically sensitive region.
