Oberdachstetten Wastewater Treatment Plant: Advanced Treatment in Bayern, Germany

The Oberdachstetten wastewater treatment plant is located in the municipality of Oberdachstetten, in the Landkreis Ansbach district of Bayern, Germany. This facility serves a population of approximately 2,560 residents, making it a small-scale treatment plant within the German wastewater infrastructure. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a design capacity of 3,500 m³/day and an average discharge volume of 647.87 m³/day, the plant operates well within its capacity, ensuring effective treatment of municipal wastewater. The treated effluent is discharged into local water bodies that eventually drain into the Rhine River basin, contributing to the overall water quality management of the region. The advanced treatment level helps protect downstream ecosystems and supports the ecological health of the receiving waters.

The plant discharges treated wastewater into local streams that flow into the Main River, a major tributary of the Rhine. The Rhine basin is a critical water resource for Central Europe, supporting diverse aquatic life and providing drinking water for millions. Advanced treatment at this plant helps reduce nutrient loads and pollutants, safeguarding the ecological balance of the downstream river system.
