Stadtgemeinde Villach is a wastewater treatment plant located in Villach, Kärnten, Austria, serving a population of about 140,149. The plant is situated in the southern part of Austria, near the Drava River, which flows through the city and eventually into the Danube basin.

The plant's capacity and treatment processes are designed to meet stringent Austrian and EU standards for nutrient removal and effluent quality. The treated wastewater is discharged into the Drava River, a major tributary of the Danube. This river system supports diverse aquatic life and is an important ecological corridor in the Alps-Adriatic region. The plant's operations help maintain water quality in the Drava and downstream ecosystems, including the Danube Delta.
