COV Valtice Wastewater Treatment Plant, Valtice, Jihomoravský kraj

COV Valtice is a municipal wastewater treatment plant located in Valtice, a town in the Jihomoravský kraj (South Moravian Region) of the Czech Republic. The plant serves a population of about 6,082 and operates under the regulatory framework of the Czech Republic, which implements the EU Urban Waste Water Treatment Directive (91/271/EEC). As a secondary treatment facility, it provides biological treatment to reduce organic pollutants and suspended solids before discharge. The plant has a designed capacity of 9,700 m³/day and currently treats an average daily flow of 800.3 m³/day, indicating ample capacity for future growth. The treatment process is secondary, which meets the EU directive requirements for agglomerations of this size (2,000-10,000 population equivalent) in non-sensitive areas. The plant is operated as part of the municipal infrastructure of Valtice, ensuring compliance with national water quality standards. 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 eventually the Black Sea. The plant plays a crucial role in protecting the water quality of the Dyje River basin, which supports diverse aquatic life and is important for regional agriculture and tourism.

The treated wastewater from COV Valtice is discharged into the local stream network, which flows into the Dyje River. The Dyje River is a significant tributary of the Morava River, part of the Danube River basin that drains into the Black Sea. The Dyje River valley is ecologically sensitive, supporting diverse aquatic habitats and riparian ecosystems. The plant's secondary treatment helps reduce nutrient loads, protecting downstream water quality in this important transboundary river system.
