Overview
Anras wastewater treatment plant serves the municipality of Anras in Tirol, Austria, with a population equivalent of approximately 14,000. The plant discharges into the Drau River, a tributary of the Danube, within the Black Sea basin.
The Anras wastewater treatment plant is located in the municipality of Anras, in the Bezirk Lienz district of Tirol, Austria. Situated along the Drauradweg cycling path, the facility serves a population equivalent of about 13,969 people, placing it in the medium agglomeration category under Austrian and EU regulations. As a plant of this scale in Austria, it is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for discharges into freshwater bodies. It operates within the framework of Austrian water law, which mandates compliance with national emission standards. The treated effluent is discharged into the Drau River (Drava), which flows eastward through Austria, Slovenia, Croatia, and Hungary before joining the Danube. The Drau is an ecologically significant river supporting diverse aquatic life and is part of the Danube basin, ultimately draining into the Black Sea. The plant's location in the Alpine region means it must manage seasonal flow variations and protect sensitive mountain stream ecosystems.
Environmental context
The plant discharges into the Drau River, a major tributary of the Danube. The Drau flows through the Eastern Alps and supports a range of fish species including grayling and brown trout. Downstream, the river passes through several countries before reaching the Danube delta, a vast wetland ecosystem. The plant's operations help protect water quality in this transboundary river system, which is important for both biodiversity and human use.
