Seukendorf Wastewater Treatment Plant, Hiltmannsdorf, Bavaria

The Seukendorf wastewater treatment plant is located in Hiltmannsdorf, a district of Seukendorf in the Bavarian district of Fürth, Germany. It serves a population of 3,651 people, classifying it as a small 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 Regnitz river basin. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU UWWTD for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive water bodies. The plant has a designed capacity of 4,900 cubic meters per day and currently discharges an average of 503.94 cubic meters per day, indicating significant spare capacity for future growth. The treated effluent is discharged into local watercourses that eventually drain into the Regnitz River, a tributary of the Main River, which flows into the Rhine and ultimately the North Sea. The advanced treatment level helps protect the ecological health of these downstream waters, supporting aquatic life and water quality in the densely populated and agriculturally active region of Bavaria.

The plant's discharge enters the local drainage network that feeds into the Regnitz River, a major tributary of the Main River within the Rhine basin. The Regnitz and Main rivers support diverse aquatic ecosystems and are important for regional biodiversity, including fish species such as barbel and chub. The advanced treatment ensures that nutrient loads are minimized, reducing the risk of eutrophication in downstream lakes and the North Sea. The plant's inland location and small population served contribute to a lower environmental footprint compared to larger coastal facilities.
