Alfeld Wastewater Treatment Plant - Bayern, Germany

Alfeld wastewater treatment plant is located in the municipality of Alfeld, within the Happurg administrative district in Landkreis Nürnberger Land, Bayern, Germany. The plant serves a population of approximately 1,920 people and is currently closed. It was designed with a capacity of 2,400 cubic meters per day and treats an average discharge volume of 485.91 cubic meters per day. The plant provides secondary treatment, which is the standard biological treatment stage required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. In Germany, secondary treatment is typically sufficient for inland plants discharging into freshwater bodies, unless the receiving water is in a sensitive area requiring more advanced treatment. The treated effluent from the plant is discharged into local watercourses that eventually drain into the Rhine River basin, which flows through Germany and the Netherlands into the North Sea. The plant's operation helps protect the water quality of the regional streams and the downstream Rhine ecosystem.

The plant discharges into local streams that are part of the Rhine River basin, one of Europe's major river systems. The Rhine supports diverse aquatic life and is an important migratory corridor for fish. The plant's secondary treatment helps reduce organic pollution and nutrient loads, protecting the ecological health of the downstream water bodies and the North Sea.
