Eppertshausen Wastewater Treatment Plant, Hessen, Germany

Eppertshausen wastewater treatment plant is located in the town of Eppertshausen, in the Landkreis Darmstadt-Dieburg district of Hessen, Germany. The facility serves a population of approximately 8,866 residents, classifying it as a small to medium agglomeration under European Union regulations. As a German plant operating under the EU Urban Waste Water Treatment Directive (91/271/EEC), Eppertshausen is required to provide at least secondary treatment for its population size. The directive mandates secondary biological treatment for agglomerations above 2,000 population equivalent, with more stringent requirements for sensitive areas. It meets the regulatory standards applicable to its scale. The treated effluent is discharged into local watercourses that drain into the Rhine River basin, ultimately reaching the North Sea. The plant plays a key role in protecting the local watershed from nutrient pollution and organic load, supporting water quality in the region's streams and rivers.

The plant discharges into the local drainage network within the Rhine River basin, which flows through Hessen and into the North Sea. The watershed supports diverse aquatic life and is an important ecological corridor. Protecting water quality in this basin is critical for downstream habitats, including floodplain forests and migratory fish populations.
