SKA HESSIGHEIM HESSIGHEIM Wastewater Treatment Plant, Hessigheim, Germany

SKA HESSIGHEIM HESSIGHEIM is a municipal wastewater treatment facility located in Hessigheim, a municipality in the Ludwigsburg district of Baden-Württemberg, Germany. The plant serves a population of around 5,100 and has a designed capacity of 6,500 cubic meters per day, with an average discharge volume of 690.57 m³/day. As an advanced treatment plant, it goes beyond secondary treatment to remove nutrients such as nitrogen and phosphorus, which is typical for plants in sensitive catchment areas under the EU Urban Waste Water Treatment Directive (91/271/EEC). Germany's implementation of this directive requires advanced treatment for agglomerations above 10,000 population equivalent in sensitive areas, but smaller plants like this one may also adopt advanced processes to protect local water quality. The treated effluent 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. The plant's advanced treatment helps reduce nutrient loading in the Neckar and Rhine, supporting aquatic ecosystems and downstream water quality in the North Sea.

The plant discharges into the Neckar River basin, which flows into the Rhine River and eventually the North Sea. The Neckar and Rhine support diverse aquatic life, including fish species such as salmon and eel, and are important migratory corridors. Advanced treatment at this plant helps minimize eutrophication risks in the downstream river system and the North Sea coastal zone.
