COV Vazec Wastewater Treatment Plant, Važec, Slovakia

COV Vazec is a wastewater treatment plant located in the village of Važec, within the Liptovský Mikuláš district of Žilinský kraj, Slovakia. The plant serves a population of approximately 1,115 residents, reflecting its role in managing domestic wastewater for this small mountain community in the High Tatras region. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 2,411 m³/day and a current discharge volume of 228.19 m³/day, the facility operates well within its capacity, ensuring effective treatment of local wastewater. The treated effluent from COV Vazec is discharged into the local watershed, which ultimately drains into the Váh River basin, the longest river in Slovakia. The Váh flows westward into the Danube River, which then reaches the Black Sea. The advanced treatment level helps protect the sensitive alpine streams and downstream aquatic ecosystems in this ecologically valuable region.

COV Vazec is situated in the High Tatras region, a mountainous area with sensitive alpine streams. The treated wastewater likely discharges into a tributary of the Váh River, which flows through northern Slovakia before joining the Danube. The advanced treatment helps protect the cold-water habitats that support native fish species and other aquatic life in this ecologically important watershed.
