Overview
Unterweitersdorf wastewater treatment plant in Unterwögern, Oberösterreich, Austria, serves a population of 2,593 with advanced treatment. It discharges 610.48 m³/day and has a designed capacity of 2,800 m³/day.
The Unterweitersdorf wastewater treatment plant is located in Unterwögern, a locality within the municipality of Unterweitersdorf in the Bezirk Freistadt district of Oberösterreich, Austria. The plant serves a population equivalent of 2,593 and operates with advanced treatment technology, reflecting Austria's commitment to high water quality standards under the EU Urban Waste Water Treatment Directive (91/271/EEC). As an advanced treatment facility, Unterweitersdorf goes beyond secondary treatment to remove nutrients such as nitrogen and phosphorus, which is typical for plants discharging into sensitive water bodies. The plant has a designed capacity of 2,800 m³/day and currently treats an average daily flow of 610.48 m³/day, indicating ample reserve capacity for future growth. The treated effluent is discharged into a local watercourse that ultimately drains into the Danube River basin. The Danube is one of Europe's most important rivers, flowing through multiple countries into the Black Sea. The advanced treatment at Unterweitersdorf helps protect downstream aquatic ecosystems and supports the ecological health of the Danube watershed.
Environmental context
The plant discharges into a small tributary of the Danube River basin, which flows through the Mühlviertel region of Upper Austria. The Danube River supports diverse aquatic life and is a critical migratory corridor for fish species. Advanced nutrient removal at the plant helps prevent eutrophication in downstream waters, including the Black Sea, which is sensitive to nutrient pollution from upstream sources.
