Vogtareuth Wastewater Treatment Plant, Bavaria, Germany

The Vogtareuth wastewater treatment plant is located in the municipality of Vogtareuth, in the Landkreis Rosenheim district of Bavaria, Germany. It serves a population of approximately 2,927 people, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). The plant is situated inland, away from coastal areas. The facility employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU UWWTD for agglomerations of this size. With a designed capacity of 4,000 m³/day and an actual discharge volume of 508.29 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into local water bodies that ultimately drain into the Inn River, a major tributary of the Danube. The Danube then flows into the Black Sea. The advanced treatment ensures high-quality effluent, protecting the sensitive aquatic ecosystems of the Inn and Danube basins.

The plant discharges into local streams that feed into the Inn River, which joins the Danube and flows into the Black Sea. The Inn-Danube system supports diverse aquatic life and is an important migratory corridor for fish. The advanced treatment level helps protect these waters from nutrient pollution and other contaminants.
