COV Tatranska Kotlina Wastewater Treatment Plant, Lendak, Slovakia

COV Tatranska Kotlina is a municipal wastewater treatment plant located in Lendak, within the Prešovský kraj region of Slovakia. The facility serves a population of 672 and operates with secondary treatment, a standard level for small agglomerations under the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant's designed capacity is 421 m³/day, with an average daily discharge of 137.53 m³/day. As a secondary treatment plant, COV Tatranska Kotlina provides biological treatment to reduce organic matter and suspended solids. For small agglomerations like this, the EU directive requires secondary treatment as a minimum, ensuring compliance with effluent quality standards. The plant's capacity utilization suggests it operates well within its design limits. The treated effluent is discharged into local watercourses that eventually drain into the Poprad River basin, part of the larger Vistula River system flowing to the Baltic Sea. The surrounding area is ecologically sensitive, supporting diverse aquatic life in the Tatra Mountains foothills. Proper treatment helps protect downstream water quality and biodiversity.

The plant discharges into the Poprad River basin, which flows northward into Poland and joins the Dunajec River, a tributary of the Vistula River that ultimately reaches the Baltic Sea. The region is part of the Tatra Mountains ecosystem, known for its unique flora and fauna. Effective secondary treatment is crucial to prevent nutrient enrichment and protect sensitive aquatic habitats in this mountainous watershed.
