Hollfeld Wastewater Treatment Plant: Serving Hollfeld, Bavaria, Germany

The Hollfeld wastewater treatment plant is located in the town of Hollfeld, in the Bavarian district of Landkreis Bayreuth, Germany. Serving a population of around 4,500, the plant is part of the municipal infrastructure that manages wastewater from the local community and surrounding areas. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations with a population equivalent between 2,000 and 10,000 are required to provide secondary treatment. As a plant serving approximately 4,500 people, Hollfeld is expected to meet this standard, ensuring that effluent is treated to reduce organic matter and suspended solids before discharge. The treated wastewater from the plant is discharged into local watercourses that flow into the Wiesent River, a tributary of the Regnitz and ultimately the Main River, which drains into the Rhine basin. The plant plays a key role in protecting the water quality of these rivers and the broader Rhine ecosystem, supporting aquatic life and downstream uses.

The Hollfeld plant discharges into the local watershed that feeds the Wiesent River, a tributary of the Regnitz River, which flows into the Main and eventually the Rhine River. The Rhine basin is a major European waterway supporting diverse aquatic ecosystems and providing drinking water for millions. The plant's treatment helps maintain water quality in this ecologically sensitive region, which is home to species such as the European eel and various freshwater fish.
