UWWTP_CRNA NA KOROSKEM is a wastewater treatment plant located in Črna na Koroškem, a town in northern Slovenia near the Austrian border. The plant serves a population of 554, classifying it as a small agglomeration under EU regulations. Its location in the Meža Valley places it within a mountainous, forested region with dispersed settlements. As a small Slovenian plant, it is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for discharges into freshwater. For agglomerations under 2,000 population equivalent, the directive mandates secondary treatment or equivalent, though member states may apply less stringent requirements for certain areas. The plant discharges into the Meža River, a tributary of the Drava River, which flows into the Danube and ultimately the Black Sea. The Meža River supports diverse aquatic life and is important for local biodiversity. The plant's operation helps protect water quality in this sensitive alpine watershed.
