SKA Backnang Sachsenweiler - Advanced Wastewater Treatment in Backnang, Baden-Württemberg

SKA Backnang Sachsenweiler is an advanced wastewater treatment plant located in the Sachsenweiler district of Backnang, in the Rems-Murr-Kreis district of Baden-Württemberg, Germany. The plant serves a population of approximately 2,450 residents and is part of the municipal wastewater infrastructure for the city of Backnang. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 1,840 m³/day and an actual discharge volume of 620.04 m³/day, the plant operates well within its capacity. As a German facility, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates advanced treatment for sensitive areas and agglomerations of this scale. The treated effluent is discharged into local water bodies that ultimately drain into the Neckar River basin, a major tributary of the Rhine. The plant plays a key role in protecting the water quality of the Neckar and Rhine systems, supporting aquatic life and downstream ecosystems.

The plant discharges into the local watershed of the Murr River, a tributary of the Neckar River, which flows into the Rhine River and eventually the North Sea. The Neckar basin is ecologically sensitive, supporting diverse aquatic species and serving as an important migratory corridor for fish. Advanced treatment at this plant helps reduce nutrient loading, protecting downstream water quality and preventing eutrophication in the Rhine delta.
