Overview
ARA Fritztal Huttau is a wastewater treatment plant in Salzburg, Austria, serving approximately 7,894 people. It operates under the EU Urban Waste Water Treatment Directive.
ARA Fritztal Huttau is a wastewater treatment plant located along the B99 road in Huttau, within the state of Salzburg, Austria. The plant serves a population of around 7,894, classifying it as a small to medium agglomeration under EU regulations. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), plants serving between 2,000 and 10,000 population equivalents are required to provide secondary treatment. It is expected to comply with this standard, ensuring adequate biological treatment before discharge. The plant's treated effluent is discharged into local watercourses that ultimately drain into the Salzach River, a major tributary of the Inn River, which flows into the Danube. This positions the plant within the Danube River Basin, a critical European watershed supporting diverse aquatic ecosystems and downstream communities.
Environmental context
The plant discharges into the Fritztal valley, part of the Salzach River catchment. The Salzach flows northward to join the Inn River, which then feeds the Danube. This basin supports sensitive aquatic habitats, including fish spawning grounds and migratory corridors. The region's alpine terrain influences seasonal flow variations, making consistent treatment important for downstream water quality.
