COV Blatnice pod Svatym Antoninkem - Secondary Wastewater Treatment Plant in Jihomoravský kraj

COV Blatnice pod Svatym Antoninkem is a municipal wastewater treatment facility located in the village of Blatnice pod Svatým Antonínkem in the Jihomoravský kraj (South Moravian Region) of the Czech Republic. The plant serves a population of approximately 1,500 people, classifying it as a small agglomeration under EU classification. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for discharges into freshwater bodies from agglomerations of this size. The plant has a designed capacity of 3,440 m³/day and currently treats an average daily volume of about 393 m³, indicating ample reserve capacity. The treated effluent is discharged into local streams that eventually flow into the Morava River basin, part of the Danube River system. This ultimately drains into the Black Sea. The plant plays a key role in protecting the local aquatic environment from nutrient pollution and organic loading.

The plant discharges into small watercourses in the Morava River basin, which is part of the larger Danube River system flowing into the Black Sea. The region is agriculturally intensive, and the plant helps reduce nutrient loads that could otherwise contribute to eutrophication in downstream reservoirs and the Black Sea. The local watershed supports diverse aquatic life and is an important corridor for migratory fish species.
