COV Hranovnica Wastewater Treatment Plant, Hranovnica, Slovakia

COV Hranovnica is a municipal wastewater treatment plant located in Hranovnica, a village in the Poprad District of Prešovský kraj, Slovakia. The plant serves a population of approximately 963 residents, making it a small-scale facility within the region's wastewater infrastructure. It operates under Slovak national regulations, which transpose the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant provides secondary treatment, which is the standard level required by the EU directive for agglomerations of this size. Its designed capacity is 1,000 m³/day, and the reported discharge volume is 197.08 m³/day, indicating that the plant operates well below its capacity. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into a local watercourse, which ultimately flows into the Poprad River basin. The Poprad River is a major tributary of the Dunajec River, which forms part of the Vistula River system and drains into the Baltic Sea. The plant plays a key role in protecting the water quality of this river network and the downstream environment.

The plant discharges into a local stream that feeds into the Poprad River, a significant watercourse in northern Slovakia. The Poprad River flows through the Poprad Basin and eventually joins the Dunajec River on the Polish border, which is part of the Vistula River basin draining to the Baltic Sea. The surrounding area is ecologically sensitive, supporting diverse aquatic life and serving as a habitat for fish species such as brown trout and grayling. The plant's secondary treatment helps reduce nutrient and organic pollution, safeguarding the river's ecological health.
