Eussenheim Wastewater Treatment Plant, Aschfeld, Bavaria

The Eussenheim wastewater treatment plant is located in Aschfeld, within the municipality of Eußenheim in the Main-Spessart district of Bavaria, Germany. Serving a population of approximately 6,859, the plant is part of the region's municipal wastewater infrastructure, handling domestic sewage from the local community. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), Germany classifies agglomerations with a population equivalent (PE) between 2,000 and 10,000 as requiring secondary treatment. As a plant serving around 6,859 people, Eussenheim is expected to meet secondary treatment standards, which involve biological treatment to reduce organic matter and suspended solids. The plant's discharge is regulated by German water law, which implements the directive's requirements for monitoring and compliance. The treated effluent from the Eussenheim plant is discharged into local watercourses that ultimately drain into the Main River, a major tributary of the Rhine. The Rhine basin is one of Europe's most important river systems, supporting diverse aquatic life and providing water for millions of people. The plant's operations contribute to protecting the water quality of these downstream environments.

The Eussenheim plant discharges into local streams that flow into the Main River, which joins the Rhine near Mainz. The Rhine is a vital European waterway, supporting extensive biodiversity and serving as a drinking water source for many communities. The plant's treatment helps reduce nutrient and organic pollution, safeguarding the ecological health of the Main-Rhine system and its downstream delta in the Netherlands.
