Pfatter Wastewater Treatment Plant, Pfatter, Bayern, Germany

Pfatter wastewater treatment plant is located in the municipality of Pfatter, in the Landkreis Regensburg district of Bayern, Germany. The plant serves a population of approximately 2,698 residents, classifying it as a small agglomeration under German and EU regulations. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 6,000 m³/day and an average discharge volume of 465.77 m³/day, the facility operates well within its capacity, ensuring effective treatment of municipal wastewater. The treated effluent is discharged into local watercourses that ultimately drain into the Danube River basin. The Danube is a major European river that flows into the Black Sea, supporting diverse aquatic ecosystems along its course. The advanced treatment level helps protect downstream water quality and ecological health.

The plant discharges into the Danube River basin, which flows through multiple countries before reaching the Black Sea. The Danube supports a rich diversity of fish and bird species, including several migratory fish. Advanced treatment at this plant helps reduce nutrient loads and pollutants, contributing to the ecological health of the downstream river system and the Black Sea.
