Overview
Au id Hallertau wastewater treatment plant serves Enzelhausen, Germany, treating wastewater for approximately 10,640 people. The plant operates under Germany's implementation of the EU Urban Waste Water Treatment Directive.
The Au id Hallertau wastewater treatment plant is located in Enzelhausen, a district of Au in der Hallertau in Bavaria, Germany. It serves a population of around 10,640 people, classifying it as a medium-sized agglomeration under EU regulations. The plant is situated in the rural Hallertau region, known for its hop-growing areas. As a German wastewater facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. Germany has implemented this directive through its national water legislation, ensuring compliance with stringent effluent standards. The regulatory framework mandates appropriate treatment to protect receiving waters. The treated effluent is discharged into local watercourses that drain into the Abens River, a tributary of the Danube. The Danube ultimately flows into the Black Sea. The plant plays a key role in maintaining water quality in the Abens catchment, supporting aquatic life and downstream ecosystems in the Danube basin.
Environmental context
The plant discharges into the Abens River, which flows into the Danube River and eventually reaches the Black Sea. The Abens catchment supports diverse aquatic habitats, including fish spawning grounds and riparian zones. The plant's operations help protect these ecosystems from nutrient pollution and organic loads, which is critical for maintaining water quality in the Danube basin.
