Mogendorf Wastewater Treatment Plant | Rheinland-Pfalz, Germany

The Mogendorf wastewater treatment plant is located in the town of Mogendorf, within the Westerwaldkreis district of Rheinland-Pfalz, Germany. It serves a population of approximately 3,000 residents, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). The plant is situated inland, away from coastal areas, and its operations are integral to local water management. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU UWWTD for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive water bodies. The plant has a designed capacity of 3,000 cubic meters per day and currently treats an average daily volume of 551.14 cubic meters, indicating ample reserve capacity. The treated effluent is discharged into local watercourses that ultimately drain into the Rhine River basin. The Rhine is a major European waterway, and its ecological health is protected under the EU Water Framework Directive. The advanced treatment at Mogendorf helps reduce nutrient loading, supporting downstream aquatic ecosystems and biodiversity in the Rhine catchment.

The plant discharges into small streams within the Westerwald region, which flow into the Wied River, a tributary of the Rhine. The Rhine basin supports diverse aquatic life, including migratory fish species such as salmon and eel. Advanced treatment at Mogendorf reduces phosphorus and nitrogen loads, mitigating eutrophication risks in downstream lakes and the North Sea.
