Ulmen Wastewater Treatment Plant, Ulmen, Rheinland-Pfalz, Germany

The Ulmen wastewater treatment plant is located in the town of Ulmen, in the Landkreis Cochem-Zell region of Rheinland-Pfalz, Germany. It serves a population of approximately 3,354 residents, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU directive for agglomerations of this size. With a designed capacity of 4,200 m³/day and an average daily discharge volume of 547.95 m³/day, the facility operates well within its capacity, ensuring effective treatment of municipal wastewater. The treated effluent is discharged into local water bodies that ultimately drain into the Rhine River basin, contributing to the protection of the Rhine's ecological health. The advanced treatment level helps reduce nutrient loads and pollutants, supporting downstream aquatic life and water quality in the region.

The plant discharges into local streams that flow into the Moselle River, a major tributary of the Rhine. The Rhine basin is ecologically significant, supporting diverse fish species and serving as a migratory corridor for birds. Advanced treatment at this plant helps minimize nutrient pollution, protecting downstream habitats and water quality in the Rhine delta.
