Mauthausen Ost Wastewater Treatment Plant, Albern, Oberösterreich

Mauthausen Ost is a wastewater treatment plant serving the community of Albern, near Mauthausen in the state of Oberösterreich, Austria. The plant handles wastewater from a population of around 22,978, placing it in the medium agglomeration category under EU classification. As an Austrian facility, Mauthausen Ost operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. The plant's design and operation align with these regulatory standards to ensure effective treatment. The treated effluent from Mauthausen Ost is discharged into the Danube River basin, which flows through Austria and several other countries before reaching the Black Sea. This river system supports diverse aquatic life and is an important ecological corridor in Central Europe. The plant's operations contribute to protecting water quality in the Danube watershed.

The plant discharges into the Danube River basin, which ultimately drains into the Black Sea. The Danube is a major European waterway supporting diverse aquatic ecosystems and providing habitat for numerous fish species. Downstream areas include the Danube Delta, an ecologically sensitive region that relies on good water quality from upstream sources.
