Reinsfeld Wastewater Treatment Plant, Rheinland-Pfalz, Germany

The Reinsfeld wastewater treatment plant is located in the municipality of Reinsfeld, within the Hermeskeil region of Rheinland-Pfalz, Germany. It serves a population of approximately 3,053 people, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). The plant provides secondary treatment, which is the minimum standard required by the UWWTD for freshwater discharges from agglomerations of this size. As a German facility, the plant operates under the national implementation of the EU UWWTD, which mandates secondary treatment for all discharges to freshwater from agglomerations above 2,000 population equivalent. The plant's designed capacity of 4,600 cubic meters per day indicates it is sized to handle peak flows and future growth. The current discharge volume of 772.64 cubic meters per day suggests the plant is operating well below its capacity. The treated effluent is discharged into local watercourses that eventually drain into the Moselle River basin, a tributary of the Rhine. The Rhine basin is one of Europe's most important river systems, supporting diverse aquatic life and providing drinking water for millions. The plant's secondary treatment helps protect downstream water quality in this ecologically significant watershed.

The plant discharges into local streams that flow into the Moselle River, a major tributary of the Rhine. The Rhine basin supports a wide range of aquatic species, including migratory fish like salmon and eel. Secondary treatment reduces organic pollutants and suspended solids, helping to maintain water quality in this densely populated and agriculturally active region. The Moselle eventually joins the Rhine, which flows into the North Sea, making the plant's performance relevant to both local and international water quality goals.
