Freihung Wastewater Treatment Plant, Elbart, Bavaria, Germany

The Freihung wastewater treatment plant is located in Elbart, a district of Freihung in the Bavarian region of Germany. It serves a population of approximately 3,454 people, classifying it as a small to medium agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). The plant is situated inland, away from coastal areas, and its operations are part of the regional water management infrastructure in the Amberg-Sulzbach district. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU UWWTD for agglomerations of this size. With a designed capacity of 3,000 m³/day and an actual discharge volume of 847.15 m³/day, the facility operates well within its capacity, indicating effective treatment and management. The advanced treatment level ensures high-quality effluent, reducing nutrient loads and protecting the receiving environment. The treated effluent from the Freihung plant is discharged into local water bodies that eventually drain into the Danube River basin, contributing to the Black Sea watershed. The advanced treatment helps safeguard the ecological health of downstream rivers and streams, supporting aquatic biodiversity and water quality in the region.

The Freihung plant discharges into local streams that flow into the Vils River, a tributary of the Naab River, which joins the Danube near Regensburg. The Danube ultimately drains into the Black Sea. The watershed supports diverse aquatic life, including fish species such as barbel and chub, and the advanced treatment helps prevent eutrophication in downstream waters.
