Aufsess Wastewater Treatment Plant, Heckenhof, Bavaria

The Aufsess wastewater treatment plant is located in Heckenhof, a locality within the municipality of Aufseß in the Bavarian district of Bayreuth, Germany. The plant serves a population of approximately 2,243 people and operates under Germany's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC). As a secondary treatment facility, the plant provides biological treatment to reduce organic matter and suspended solids. Its designed capacity is 3,000 m³ per day, with an average daily discharge of 567.65 m³, indicating a utilization rate well below capacity. The plant is classified as a small agglomeration under EU regulations, which require secondary treatment as a minimum standard. The treated effluent is discharged into local watercourses within the Upper Main basin, part of the Rhine-Main-Danube watershed. The region is characterized by rural agricultural landscapes and small streams that flow into the Main River, ultimately reaching the North Sea via the Rhine. The plant plays a key role in protecting local water quality and supporting the ecological health of these waterways.

The plant discharges into small streams in the Upper Main basin, which flow into the Main River, a major tributary of the Rhine. The Rhine eventually drains into the North Sea. The surrounding watershed supports diverse aquatic life and is important for regional biodiversity, with the plant's secondary treatment helping to reduce nutrient loads and organic pollution in these sensitive freshwater systems.
