ARA GAV Drasenhofen 981 MI - Advanced Wastewater Treatment in Drasenhofen, Niederösterreich

ARA GAV Drasenhofen 981 MI is a wastewater treatment plant located in the Katastralgemeinde Drasenhofen, within the municipality of Drasenhofen in the Bezirk Mistelbach, Niederösterreich, Austria. The plant serves a population of approximately 2,444 and has a designed capacity of 7,300 m³/day, with an actual discharge volume of 534.05 m³/day. The plant employs advanced treatment processes, which go 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 receiving waters. As an Austrian plant, it operates under national regulations that implement the EU directive, ensuring high effluent quality standards. The treated effluent from the plant is discharged into local watercourses that eventually drain into the Danube River basin. The Danube flows eastward through Central and Eastern Europe before reaching the Black Sea. The plant's advanced treatment helps protect the ecological health of these downstream waters, which support diverse aquatic life and are used for recreation and drinking water supply.

The plant discharges into local streams that are part of the Danube River basin. The Danube is one of Europe's most important waterways, flowing through multiple countries and supporting rich biodiversity, including migratory fish species. The advanced treatment at this plant reduces nutrient loads, helping to prevent eutrophication in downstream lakes and the Black Sea. The region's agricultural land use also benefits from reduced pollution loads.
