COV Tatranska Kotlina BTH1 - Secondary Wastewater Treatment Plant in Lendak, Slovakia

COV Tatranska Kotlina BTH1 is a wastewater treatment plant located in Lendak, within the Prešovský kraj region of Slovakia. The facility serves a small population of 14 people, reflecting its role in a rural or remote area near Tatranská Lomnica. As a secondary treatment plant, it provides biological treatment to reduce organic pollutants before discharge. The plant has a designed capacity of 35.00 m³/day and currently discharges 2.87 m³/day of treated effluent. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), small agglomerations like this are typically required to provide appropriate treatment, and secondary treatment meets the standard for sensitive areas. The plant operates within Slovakia's national regulatory framework, which aligns with EU directives. The treated effluent is discharged into local watercourses that drain into the Poprad River basin, eventually reaching the Baltic Sea via the Dunajec and Vistula rivers. The surrounding area is part of the Tatra Mountains region, known for its sensitive alpine ecosystems and biodiversity. The plant's secondary treatment helps protect these downstream environments from nutrient pollution.

The plant discharges into the Poprad River basin, which flows through the Tatra Mountains into the Dunajec River, then the Vistula River, and ultimately the Baltic Sea. This alpine watershed supports sensitive ecosystems, including protected fish species and riparian habitats. The secondary treatment process reduces organic load and helps maintain water quality in this ecologically important region.
