COV Liptovska Osada Wastewater Treatment Plant, Liptovská Osada, Slovakia

COV Liptovska Osada is a municipal wastewater treatment plant located in Liptovská Osada, a village in the Ružomberok district of Žilinský kraj, central Slovakia. The plant serves a population of 1,562 and operates with secondary treatment, which is appropriate for small agglomerations under Slovak and EU regulations. As a secondary treatment facility, the plant removes organic matter and suspended solids through biological processes. Its designed capacity is 3,686 m³/day, with an actual discharge volume of 319.67 m³/day, indicating ample reserve capacity. The plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The treated effluent is discharged into local waterways that drain into the Váh River basin, ultimately flowing into the Danube River and the Black Sea. The plant plays a key role in protecting the water quality of the Váh River and its tributaries, supporting aquatic life and downstream ecosystems.

The plant discharges into the Váh River basin, part of the Danube River system that flows into the Black Sea. The Váh is the longest river in Slovakia and supports diverse aquatic habitats. The region is characterized by mountainous terrain and forests, and the plant helps maintain water quality in this ecologically sensitive area, preventing nutrient pollution that could affect downstream reservoirs and the Danube Delta.
