SKA Bönnigheim Wastewater Treatment Plant, Bönnigheim, Baden-Württemberg

SKA Bönnigheim is a municipal wastewater treatment plant located in Bönnigheim, a town in the Ludwigsburg district of Baden-Württemberg, Germany. The plant serves a population of around 12,000 residents, classifying it as a small to medium agglomeration under European Union regulations. As a German wastewater 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. Germany implements this directive through its national water management laws, ensuring that treated effluent meets stringent quality standards before discharge. The plant's treated wastewater is discharged into local watercourses that ultimately drain into the Neckar River basin, a major tributary of the Rhine. The Rhine flows through Germany and the Netherlands into the North Sea, making the plant part of a large international watershed that supports diverse aquatic ecosystems and provides drinking water for millions.

The plant discharges into the Neckar River basin, which flows into the Rhine River and eventually the North Sea. This watershed supports diverse aquatic life, including fish species such as salmon and trout, and provides critical habitat for migratory birds. The region's water quality is closely monitored to protect downstream ecosystems and drinking water sources.
