COV Sanov Wastewater Treatment Plant, Hrabětice, South Moravian Region

COV Sanov is a wastewater treatment plant located in Hrabětice, within the Jihomoravský kraj (South Moravian Region) of the Czech Republic. The facility serves a population of approximately 1,744 people, classifying it as a small agglomeration under Czech and EU regulations. The plant is situated in a rural area near the border with Austria, within the Dyje river basin. The plant provides secondary treatment, which is the minimum required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant has a designed capacity of 2,250 m³/day, with a current discharge volume of 221.92 m³/day, indicating significant spare capacity. 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 basin, which supports diverse aquatic life and is used for agriculture and recreation.

The plant discharges into the Dyje River basin, which flows through the South Moravian region and joins the Morava River near the Czech-Austrian-Slovak border. The Morava then flows into the Danube, eventually reaching the Black Sea. The Dyje River is ecologically significant, supporting diverse fish populations and riparian habitats. The region is known for its agricultural landscape and the Pálava Protected Landscape Area, though the plant itself is not within a designated protected area.
