SKA Schwabisch Hall Sulzdorf Wastewater Treatment Plant, Schwäbisch Hall, Baden-Württemberg

SKA Schwabisch Hall Sulzdorf is a municipal wastewater treatment plant located in the Sulzdorf district of Schwäbisch Hall, Baden-Württemberg, Germany. The plant serves a population of approximately 5,350 residents, classifying it as a small agglomeration under EU regulations. 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 set by the German Water Resources Act (WHG) and the Wastewater Ordinance (AbwV). Treated effluent from the plant is discharged into local watercourses that ultimately drain into the Kocher River, a tributary of the Neckar River, which flows into the Rhine River and then the North Sea. The plant plays a key role in protecting the water quality of the Kocher and downstream ecosystems.

The plant discharges into the Kocher River basin, which is part of the larger Rhine catchment. The Kocher flows through the Swabian-Franconian Forest and supports diverse aquatic life, including fish species such as brown trout and grayling. Downstream, the Neckar and Rhine rivers are important ecological corridors in Central Europe. The plant's treatment helps maintain water quality in these sensitive freshwater habitats.
