UWWTP_VOJNA VAS CRNOMELJ is a municipal wastewater treatment plant located near Črnomelj, Slovenia, in the region of White Carniola. The plant serves a population of approximately 5,200, classifying it as a small to medium agglomeration under Slovenian and EU regulations. The plant provides secondary treatment, which is the minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. Its designed capacity is 9,600 m³/day, with an average discharge volume of about 837 m³/day, indicating ample reserve capacity. The treated effluent is discharged into the local water system, which flows into the Lahinja River and eventually the Kolpa River, a tributary of the Sava River.
