SKA AZV UNTERES KOCHERTAL Wastewater Treatment Plant, Degmarn, Baden-Württemberg

SKA AZV UNTERES KOCHERTAL is a municipal wastewater treatment plant located in Degmarn, a district of Oedheim in the Heilbronn district of Baden-Württemberg, Germany. The plant serves a population of approximately 25,250 people, classifying it as a medium-sized agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). As a German plant, it operates under the EU UWWTD (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more stringent treatment if the receiving waters are designated as sensitive areas. It is expected to meet national standards for biological treatment. The treated effluent is discharged into the Kocher River, which flows into the Neckar River, a major tributary of the Rhine. The Rhine ultimately drains into the North Sea. The plant plays a key role in protecting the water quality of the Kocher and downstream ecosystems, supporting aquatic life and recreational uses.

The plant discharges into the Kocher River, which flows through the Swabian-Franconian forest and joins the Neckar near Bad Friedrichshall. The Neckar then flows into the Rhine, one of Europe's major rivers. The watershed supports diverse aquatic habitats and is important for migratory fish species. The region is characterized by mixed agricultural and industrial land use, making effective wastewater treatment essential for maintaining water quality.
