COV Okoc Wastewater Treatment Plant, Okoč, Trnavský kraj, Slovakia

COV Okoc is an advanced wastewater treatment plant located in Okoč, within the Dunajská Streda district of Trnavský kraj, Slovakia. The facility serves a small population of 107 residents, reflecting its role in a rural or small community setting. The plant is part of Slovakia's wastewater infrastructure, which is regulated under the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU directive for agglomerations of this size. Its designed capacity of 3,000 m³/day indicates it is sized to accommodate future growth or seasonal variations. The actual discharge volume is 21.90 m³/day, showing low utilization relative to capacity. The treated effluent is discharged into local water bodies that ultimately drain into the Danube River basin, a major European watershed. The plant's advanced treatment helps protect downstream ecosystems, including the Danube Delta and the Black Sea, by reducing nutrient loads and pollutants.

The plant discharges into local streams that feed into the Danube River basin, which flows through several countries before reaching the Danube Delta and the Black Sea. The Danube Delta is an ecologically sensitive area that supports diverse aquatic life and migratory bird populations. Advanced treatment at this plant helps minimize nutrient pollution, which is critical for preventing eutrophication in downstream waters.
