ARA GV Abwasserbeseitigung Raum Bad Voslau 2900 BN - Wastewater Treatment in Bad Vöslau, Austria

ARA GV Abwasserbeseitigung Raum Bad Voslau 2900 BN is a municipal wastewater treatment plant located in Bad Vöslau, Niederösterreich, Austria. It serves a population of 77,646, classifying it as a medium-to-large agglomeration under EU standards. As an Austrian plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. For plants serving over 10,000 population equivalent in sensitive areas, tertiary treatment may be mandated to reduce nutrient loads. The plant discharges treated effluent into local watercourses that ultimately drain into the Danube River basin. The Danube flows eastward through Central Europe into the Black Sea, supporting diverse aquatic ecosystems and providing water for agriculture and industry along its course.

The plant's treated effluent enters the local drainage network, which feeds into the Danube River basin. The Danube is a major European waterway that supports rich biodiversity, including migratory fish species and wetland habitats. Downstream, the river flows through the Danube Delta before reaching the Black Sea, an ecologically sensitive area that relies on nutrient management to prevent eutrophication.
