ARA Prottes 1241 GF Wastewater Treatment Plant, Gänserndorf, Niederösterreich

ARA Prottes 1241 GF is a wastewater treatment plant located in Gänserndorf, in the state of Niederösterreich, Austria. The plant serves a population of approximately 2,293 people and has a designed capacity of 3,200 cubic meters per day, with an average discharge volume of 377.49 cubic meters per day. The plant employs advanced treatment processes, which go beyond the secondary treatment requirements mandated by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. This level of treatment is typically required in sensitive areas to reduce nutrient loads and protect receiving water bodies. The treated effluent is discharged into local waterways that ultimately drain into the Danube River basin, which flows into the Black Sea. The plant plays a key role in protecting the region's water quality and supporting downstream aquatic ecosystems.

The plant discharges into local streams that are part of the Danube River basin. The Danube is one of Europe's most important rivers, supporting diverse aquatic life and providing water for millions of people. The advanced treatment at this plant helps reduce nutrient pollution, which is critical for preventing eutrophication in downstream waters, including the Black Sea.
