COV Krasnohorske Podhradie - Advanced Wastewater Treatment in Krásnohorské Podhradie, Slovakia

COV Krasnohorske Podhradie is a municipal wastewater treatment plant located in Krásnohorské Podhradie, a village in the Rožňava District of Košický kraj, eastern Slovakia. The plant serves a population of 2,278, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU UWWTD for agglomerations of this size. With a designed capacity of 2,500 m³/day and an average daily discharge of 466.20 m³/day, the facility operates well below its capacity, indicating room for future growth or seasonal variability. The treated effluent is discharged into a local watercourse that drains into the Slaná River, a tributary of the Tisza River, which ultimately flows into the Danube River and the Black Sea. The plant plays a key role in protecting the water quality of the Slaná River basin, which supports diverse aquatic life and is used for recreation and agriculture.

The plant discharges into a small stream that feeds the Slaná River, a major river in southern Slovakia. The Slaná River flows into the Tisza River, which crosses into Hungary and eventually reaches the Danube River and the Black Sea. The watershed supports a variety of fish species and is an important ecological corridor in the Carpathian region. Advanced treatment helps minimize nutrient loading and protects downstream water quality in this sensitive river system.
