COV Velke Pavlovice Wastewater Treatment Plant, Velké Pavlovice, Czech Republic

COV Velke Pavlovice is a municipal wastewater treatment plant located in Velké Pavlovice, a town in the Jihomoravský kraj (South Moravian Region) of the Czech Republic. The plant serves a population of approximately 4,954 people, placing it in the small-to-medium agglomeration category under EU classification. The plant provides secondary treatment, which is the minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for inland freshwater discharges from agglomerations of this size. With a designed capacity of 5,400 m³/day and an actual discharge volume of 721.40 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variability. The treated effluent is discharged into local watercourses that ultimately drain into the Dyje River, a tributary of the Morava River, which flows into the Danube River and then the Black Sea. The plant plays a key role in protecting the water quality of the Dyje River basin and downstream ecosystems, including the UNESCO-listed Lednice-Valtice Cultural Landscape area, which relies on clean water for its aquatic habitats.

The plant discharges into the Dyje River basin, which flows into the Morava River, a major tributary of the Danube. The Danube ultimately reaches the Black Sea. The region includes ecologically sensitive areas such as the Lednice-Valtice Cultural Landscape, a UNESCO site with extensive fishponds and wetlands that depend on good water quality. Secondary treatment helps reduce organic pollution and nutrient loads, supporting aquatic biodiversity in the Dyje and downstream waters.
