COV Kecerovce Wastewater Treatment Plant, Kecerovce, Slovakia

COV Kecerovce is a municipal wastewater treatment plant located in Kecerovce, a village in the Košice - okolie district of eastern Slovakia. The plant serves a population of 1,548, classifying it as a small agglomeration under Slovak and EU regulations. It is situated inland, away from coastal areas, and its operations are part of the region's water management infrastructure. The plant provides secondary treatment, which is the minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. The designed capacity is 2,600 m³/day, and the current discharge volume is 316.80 m³/day, indicating operational headroom. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into local watercourses that ultimately drain into the Hornád River basin, a tributary of the Tisza River, which flows into the Danube and then the Black Sea. The plant plays a key role in protecting the water quality of these downstream ecosystems, supporting aquatic life and preventing eutrophication in sensitive areas.

The plant discharges into the Hornád River basin, which flows through eastern Slovakia into Hungary, joining the Tisza River. The Tisza is a major tributary of the Danube, ultimately reaching the Black Sea. This watershed supports diverse aquatic habitats and is important for migratory fish species. The region's inland location means the effluent undergoes natural dilution in rivers, but secondary treatment is essential to prevent nutrient loading and maintain ecological balance.
