Oberes Ellerbachtal Weinsheim Wastewater Treatment Plant, Weinsheim, Rheinland-Pfalz

Oberes Ellerbachtal Weinsheim is a wastewater treatment facility located in Weinsheim, a municipality in the Bad Kreuznach district of Rheinland-Pfalz, Germany. The plant serves a population of approximately 5,013, classifying it as a small to medium agglomeration under European Union standards. It is situated inland, away from coastal areas, and its operations are integral to the local water management infrastructure. The plant employs advanced treatment processes, which go beyond the secondary treatment mandated by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 8,000 cubic meters per day and a current discharge volume of about 891 cubic meters per day, the facility operates well within its capacity, ensuring effective treatment of wastewater from the community. The treated effluent is discharged into the local watershed, which ultimately drains into the Rhine River basin. This contributes to the protection of downstream ecosystems, including the Rhine's diverse aquatic habitats. The plant's advanced treatment helps reduce nutrient loads and pollutants, supporting water quality in the region's rivers and streams.

The plant discharges into the Ellerbach stream, a tributary of the Nahe River, which flows into the Rhine River near Bingen. The Rhine is a major European waterway supporting diverse aquatic life and serving as a critical migratory corridor for fish species. The advanced treatment at Oberes Ellerbachtal Weinsheim helps minimize nutrient and pollutant inputs, protecting the ecological integrity of the Nahe and Rhine rivers.
