It serves a population of around 77,413, classifying it as a large agglomeration under EU regulations. The plant is situated in the Main River basin, an important tributary of the Rhine. As a German facility serving over 70,000 people, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum and tertiary treatment in sensitive areas. The regulatory framework ensures compliance with stringent discharge standards to protect water quality. The treated wastewater is discharged into the Main River, which flows into the Rhine, one of Europe's major waterways. The Rhine supports diverse aquatic life and is a crucial corridor for migratory fish. The plant plays a key role in maintaining the ecological health of this river system by reducing nutrient and pollutant loads.

The plant discharges into the Main River, a major tributary of the Rhine. The Rhine basin is ecologically significant, supporting diverse aquatic species and serving as a migratory route for fish such as salmon and eel. Downstream, the Rhine flows through the Rhine Delta into the North Sea, a sensitive marine environment. The plant's operations help protect these waters from eutrophication and pollution.
