SKA Buhlerzell Buhlerzell Wastewater Treatment Plant, Bühlerzell, Germany

SKA Buhlerzell Buhlerzell is a wastewater treatment plant located in Bühlerzell, a municipality in the Schwäbisch Hall district of Baden-Württemberg, Germany. The plant served a small agglomeration of approximately 1,750 people and was designed to handle up to 3,000 cubic meters of wastewater per day. The plant provided secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The directive mandates secondary treatment for all discharges from agglomerations with a population equivalent (PE) between 2,000 and 10,000, ensuring organic matter and suspended solids are reduced before discharge. The treated effluent from the plant was discharged into the local water system, which ultimately drains into the Bühler River, a tributary of the Kocher, and then into the Neckar River, which flows into the Rhine. The Rhine basin is a major European watershed supporting diverse aquatic life and providing drinking water for millions. The plant's closure means that wastewater from Bühlerzell is now likely treated at a neighboring facility.

The plant discharged into the Bühler River, a tributary of the Kocher, which flows into the Neckar and then the Rhine. The Rhine basin is ecologically significant, supporting migratory fish species and providing habitat for diverse aquatic organisms. The region's water quality is managed under the EU Water Framework Directive, which aims to achieve good ecological status for all water bodies.
