MARKT BEROLZHEIM Wastewater Treatment Plant, Markt Berolzheim, Bayern

The MARKT BEROLZHEIM wastewater treatment plant is located in Markt Berolzheim, a municipality in the Bavarian district of Weißenburg-Gunzenhausen, Germany. The plant served a population of 1,361 and was designed with a capacity of 2,500 m³/day, though it discharged an average of 344.44 m³/day. The facility is now closed. The plant provided advanced treatment, which goes beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive water bodies. As a German plant, it operated under the national Wasserhaushaltsgesetz (Water Resources Act) and relevant state regulations. The plant's discharge likely entered local streams within the Altmühl river basin, which flows into the Danube River and ultimately the Black Sea. The Altmühl region is known for its karst landscape and ecologically sensitive wetlands, making advanced treatment important for protecting downstream aquatic habitats and biodiversity.

The plant is situated in the Altmühl river basin, a tributary of the Danube. The Altmühl flows through the Altmühltal Nature Park, a region characterized by limestone karst and diverse aquatic ecosystems. Downstream, the Danube supports migratory fish species and extensive floodplain habitats before reaching the Black Sea. Advanced treatment at this plant helped reduce nutrient loading, protecting these downstream environments from eutrophication.
