COV Lucky Mockov Wastewater Treatment Plant, Lúčky, Slovakia

COV Lucky Mockov is a municipal wastewater treatment plant located in Lúčky, a spa village in the Žilinský region of northern Slovakia. The plant serves a population of 1,697 and has a designed capacity of 3,393 cubic meters per day, indicating it is sized for a small agglomeration. The facility provides secondary treatment, which is the standard required under the EU Urban Waste Water Treatment Directive for communities of this size in non-sensitive areas. As a secondary treatment plant, COV Lucky Mockov uses biological processes to reduce organic matter and suspended solids before discharging treated effluent. The plant's discharge volume is 347.30 cubic meters per day, reflecting a capacity utilization that suggests ample reserve for future growth or seasonal variations. The facility is operated as part of the municipal infrastructure of Lúčky, which is known for its thermal springs and tourism. The treated wastewater is discharged into a local watercourse that ultimately drains into the Váh River, the longest river in Slovakia. The Váh flows southwest into the Danube River, which then reaches the Black Sea. The plant plays a key role in protecting the water quality of the Váh basin, which supports diverse aquatic life and is used for recreation and agriculture downstream.

The plant discharges into a tributary of the Váh River, which flows through the Žilinský region and eventually joins the Danube. The Váh basin supports a variety of fish species and is an important ecological corridor in the Carpathian region. Downstream waters are used for irrigation and recreation, making effective treatment essential to prevent nutrient enrichment and maintain water quality.
