COV Pata Wastewater Treatment Plant, Pata, Trnavský kraj, Slovakia

COV Pata is a municipal wastewater treatment plant located in Pata, a village in the Trnavský kraj region of western Slovakia. The plant serves a small population of 727 residents, reflecting the rural character of the area. It operates under Slovakia's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which sets treatment standards based on agglomeration size. The plant provides secondary treatment, which is the minimum required under the EU directive for discharges into freshwater bodies. With a designed capacity of 900 m³/day and an average discharge volume of 148.78 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into local watercourses that eventually drain into the Váh River basin, a major tributary of the Danube River. The Váh River flows into the Danube, which ultimately reaches the Black Sea. The plant's operations help protect the local aquatic environment and downstream ecosystems from nutrient pollution and organic loading.

COV Pata discharges into small streams that feed into the Váh River, a significant waterway in western Slovakia. The Váh River flows into the Danube, which empties into the Black Sea. The local watershed supports diverse aquatic life and is used for agriculture and recreation. Effective wastewater treatment is crucial to prevent eutrophication and maintain water quality in this ecologically sensitive region.
