Dannstadt Wastewater Treatment Plant - Dannstadt-Schauernheim, Rhineland-Palatinate

The Dannstadt wastewater treatment plant is located in Dannstadt-Schauernheim, a municipality in the Rhein-Pfalz-Kreis district of Rhineland-Palatinate, Germany. The plant serves a population of approximately 15,857 people, placing it in the medium agglomeration category under EU regulations. As a German facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more stringent treatment if the receiving waters are designated as sensitive areas. The plant's treatment processes are designed to meet these regulatory standards, ensuring compliance with national and European water quality requirements. The treated effluent is discharged into local water bodies that ultimately drain into the Rhine River basin, a major European watershed. The Rhine flows through Germany and the Netherlands before reaching the North Sea. The plant plays a key role in protecting the local aquatic environment and downstream ecosystems from nutrient pollution and other contaminants.

The plant discharges into the Rhine River basin, which flows through Germany and the Netherlands into the North Sea. The Rhine supports diverse aquatic life and is an important migratory corridor for fish species. Downstream ecosystems include floodplain forests and wetlands that rely on good water quality. The plant's treatment helps reduce nutrient loads that could otherwise contribute to eutrophication in the North Sea.
