Altheim und Umgebung is a wastewater treatment plant located in Altheim, Oberösterreich, Austria, serving a population of around 13,372. The plant is situated in the Innviertel region, near the border with Germany, and is part of the municipal infrastructure for the town of Altheim and surrounding communities. As a medium-sized agglomeration, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for populations between 10,000 and 150,000. The directive also mandates more advanced treatment if the receiving waters are sensitive to eutrophication. The plant is expected to meet these standards. The treated effluent is discharged into local waterways that ultimately drain into the Inn River, a major tributary of the Danube. The Danube basin supports diverse aquatic ecosystems and is an important migratory corridor for fish species. The plant plays a key role in protecting water quality in this region.
Environmental context
The plant discharges into the local drainage network that flows into the Inn River, which joins the Danube near Passau. The Danube is one of Europe's most significant rivers, supporting a wide range of aquatic life and serving as a critical migratory route for species such as sturgeon. The region's watershed is part of the larger Danube basin, which empties into the Black Sea. Protecting water quality in this system is essential for maintaining ecological balance and biodiversity.
