COV Sol Wastewater Treatment Plant, Komárany, Prešovský kraj

COV Sol is a wastewater treatment plant located in Komárany, a village in the Vranov nad Topľou district of Prešovský kraj, eastern Slovakia. The plant serves a population of approximately 2,523 people, classifying it as a small agglomeration under EU standards. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 3,700 m³/day and a current discharge volume of 516.34 m³/day, the plant operates well below its capacity, indicating potential for future growth or seasonal variations. The treated effluent is discharged into a local water body, likely a tributary of the Topľa River, which flows into the Ondava River and eventually the Bodrog River, part of the Tisza River basin. This basin drains into the Black Sea, making the plant's advanced treatment important for protecting downstream aquatic ecosystems and water quality.

The plant discharges into a local stream that feeds into the Topľa River, a tributary of the Ondava River. The Ondava joins the Latorica to form the Bodrog River, which flows into the Tisza River and ultimately the Black Sea. This watershed supports diverse aquatic life and is important for regional biodiversity. Advanced treatment helps reduce nutrient loading, protecting downstream water bodies from eutrophication.
