Rehweiler Wastewater Treatment Plant, Rehweiler, Rheinland-Pfalz

The Rehweiler wastewater treatment plant is located in the municipality of Rehweiler, within the Oberes Glantal region of Landkreis Kusel, Rheinland-Pfalz, Germany. This facility serves a population of approximately 2,330 residents, reflecting its role as a small-scale municipal treatment plant in a rural setting. 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 designed capacity of 2,900 m³/day and an average discharge volume of 991.85 m³/day, the plant operates well within its capacity, ensuring effective treatment of wastewater from the local community. The treated effluent is discharged into local watercourses that eventually drain into the Glan River, a tributary of the Nahe River, which flows into the Rhine. The plant's advanced treatment helps protect the ecological health of these water bodies, supporting aquatic life and maintaining water quality in the Rhine basin.

The plant discharges into small streams that feed the Glan River, part of the Rhine basin. The Rhine is a major European waterway supporting diverse aquatic ecosystems and providing drinking water for millions. Advanced treatment at this plant reduces nutrient loads, helping to prevent eutrophication in downstream waters and protecting sensitive habitats along the river corridor.
