Koflach Sud Lankowitzbach Wastewater Treatment Plant, Köflach, Austria

Koflach Sud Lankowitzbach is a former wastewater treatment plant located in Köflach, a town in the Steiermark region of Austria. The plant was designed with a capacity of 8,000 cubic meters per day and provided advanced treatment for municipal wastewater. It is now closed, but its infrastructure contributed to local water quality management. The plant operated under Austria's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires advanced treatment for sensitive areas and agglomerations of this scale. Advanced treatment includes nutrient removal to protect receiving waters from eutrophication. The plant's discharge likely entered the Lankowitzbach stream, a tributary of the Kainach River, which flows into the Mur River and eventually the Drava and Danube. This watershed supports diverse aquatic life and is part of the larger Danube basin, a critical ecological corridor in Europe.

The plant's discharge would have entered the Lankowitzbach, a small stream that flows into the Kainach River, a tributary of the Mur. The Mur River drains into the Drava, which joins the Danube before reaching the Black Sea. This watershed supports diverse aquatic habitats and is part of a major European ecological corridor. Advanced treatment at this plant helped protect downstream water quality and prevent nutrient pollution in the Danube basin.
