ARA AV Raum Korneuburg 1448 KO Wastewater Treatment Plant, Klosterneuburg, Austria

ARA AV Raum Korneuburg 1448 KO is a municipal wastewater treatment plant located in Klosterneuburg, Niederösterreich, Austria. The plant serves a population of approximately 54,053 people, classifying it as a medium-sized agglomeration under EU regulations. It is situated near the Danube River, which is the primary receiving water body for treated effluent. As a plant serving over 50,000 people, it falls under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum. For plants in sensitive areas, tertiary treatment may be mandated. The regulatory framework ensures compliance with EU standards for nutrient removal and effluent quality. The treated wastewater is discharged into the Danube River, which flows through Austria and eventually into the Black Sea. The Danube is a major European waterway supporting diverse aquatic life and providing drinking water for millions. The plant plays a key role in protecting the river's water quality and the downstream ecosystems, including the Danube Delta, a critical wetland area.

The plant discharges into the Danube River, which flows through Austria, Slovakia, Hungary, and several other countries before reaching the Black Sea. The Danube supports a rich biodiversity, including fish species like sturgeon and migratory birds. The plant's operations help maintain water quality in this transboundary river, reducing nutrient loads that could cause eutrophication in the Black Sea.
