SKA UNTERREICHENBACH Wastewater Treatment Plant, Unterreichenbach, Germany

SKA UNTERREICHENBACH is a municipal wastewater treatment plant located in Unterreichenbach, a town in the Calw district of Baden-Württemberg, Germany. The plant serves a population of approximately 2,550, 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 directive ensures appropriate treatment standards are met. The plant discharges treated wastewater into the local water system, which ultimately drains into the Nagold River, a tributary of the Enz, Neckar, and Rhine rivers. This connection to the Rhine basin highlights the plant's role in protecting downstream aquatic ecosystems and the broader Rhine watershed.

The plant's treated effluent enters the local water network, flowing into the Nagold River, which joins the Enz, then the Neckar, and finally the Rhine River. The Rhine basin supports diverse aquatic life and is a critical migratory corridor for fish species. The plant's operation helps maintain water quality in this ecologically sensitive river system.
