Steinenbronn Wastewater Treatment Plant, Baden-Württemberg, Germany

The Steinenbronn wastewater treatment plant is located in the town of Steinenbronn, Baden-Württemberg, Germany. It serves a population of approximately 7,250 people, classifying it as a small to medium agglomeration under EU regulations. As a German plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The plant's treatment processes and capacity are designed to meet these standards, ensuring compliance with national and EU water quality goals. The treated effluent is discharged into local water bodies that ultimately drain into the Rhine River basin, supporting the ecological health of the region. The plant plays a key role in protecting downstream aquatic ecosystems and maintaining water quality in the densely populated state of Baden-Württemberg.

The plant discharges into local streams that flow into the Neckar River, a major tributary of the Rhine. The Rhine basin supports diverse aquatic life and is an important migratory corridor for fish. The region's karst geology and agricultural land use make nutrient management critical to prevent eutrophication in downstream waters.
