Friedenfels Wastewater Treatment Plant: Serving Friedenfels, Bavaria

The Friedenfels wastewater treatment plant is located in the town of Friedenfels, in the Bavarian district of Tirschenreuth, Germany. It serves a population of around 3,017 residents, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). The plant is situated in a rural, inland area of northeastern Bavaria. The plant provides secondary treatment, which is the minimum standard required by the EU UWWTD for freshwater discharges from agglomerations of this size. With a designed capacity of 7,000 m³/day and a reported discharge volume of 750.63 m³/day, the plant operates well below its capacity, indicating potential for future growth or seasonal variations. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into a local watercourse, likely a tributary of the Waldnaab River, which flows into the Naab and eventually the Danube River system. This discharge contributes to the water quality of the Danube basin, supporting aquatic life and downstream ecosystems. The plant's operation is subject to German water management regulations, which implement the EU Water Framework Directive.

The plant discharges into a small stream that feeds into the Waldnaab River, a tributary of the Naab, which joins the Danube near Regensburg. The Danube basin is a major European watershed supporting diverse aquatic species and providing water for agriculture and industry. The region's aquatic ecosystems are sensitive to nutrient pollution, making secondary treatment important for protecting downstream water quality.
