SKA Althengstett Wastewater Treatment Plant, Althengstett, Baden-Württemberg

SKA Althengstett is a municipal wastewater treatment plant located in Althengstett, a town in the Landkreis Calw district of Baden-Württemberg, Germany. The plant serves a population of approximately 12,200 residents, classifying it as a medium-sized agglomeration under EU regulations. As a German wastewater treatment facility, SKA Althengstett 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 (Wasserhaushaltsgesetz) and the Wastewater Ordinance (Abwasserverordnung). Treated effluent from the plant is discharged into local water bodies that ultimately drain into the Rhine River basin. The plant plays a crucial role in protecting the water quality of the region's streams and rivers, which support diverse aquatic ecosystems and are used for recreation and agriculture downstream.

The plant discharges into local streams that flow into the Nagold River, a tributary of the Enz River, which joins the Neckar River and eventually reaches the Rhine River. The Rhine basin is ecologically significant, supporting diverse fish populations and serving as a major migratory corridor for aquatic species. The plant's operations help maintain water quality in this sensitive watershed.
