Overview
Nauders wastewater treatment plant serves the municipality of Nauders in Tirol, Austria. The facility treats wastewater for approximately 4,124 residents in the Alpine region.
The Nauders wastewater treatment plant is located in the municipality of Nauders, Bezirk Landeck, in the Austrian state of Tirol. Situated in the Alpine region near the border with Italy, the plant serves a population of about 4,124 people, reflecting a small to medium agglomeration typical of mountain communities. As an Austrian facility, the plant 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, which is common in Alpine regions due to the ecological sensitivity of mountain streams and lakes. The treated effluent is discharged into local watercourses that drain into the Inn River, a major tributary of the Danube. The Danube ultimately flows into the Black Sea, making the plant part of a vast transboundary river basin. The Alpine watershed supports diverse aquatic life and is important for downstream water quality in the Danube ecosystem.
Environmental context
The plant discharges into local streams that feed the Inn River, which flows through Tirol and into the Danube basin. The Danube carries water through multiple countries to the Black Sea. The Alpine environment is ecologically sensitive, with cold, oxygen-rich waters that support species such as brown trout and the endangered Danube salmon. Protecting water quality in this headwater region is critical for the health of downstream ecosystems.

The plant serves approximately 4,124 residents, representing a small to medium agglomeration in the Alpine region.
The treated effluent is discharged into local streams that flow into the Inn River, a tributary of the Danube, which ultimately reaches the Black Sea.
As an Austrian facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which sets treatment standards based on population size and receiving water sensitivity.
Under the EU directive, agglomerations of this size typically require secondary treatment. In sensitive Alpine areas, additional nutrient removal may be required to protect water quality.
