COV Vizovice Wastewater Treatment Plant, Zádveřice-Raková, Zlínský kraj

COV Vizovice is a wastewater treatment plant located in Zádveřice-Raková, within the Zlínský kraj region of the Czech Republic. The plant serves a population of approximately 1,853 people and has a designed capacity of 8,000 m³/day, indicating it is sized to accommodate future growth or seasonal variations. Its advanced treatment level ensures high-quality effluent suitable for discharge into sensitive environments. The plant operates under the Czech Republic's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size (under 2,000 population equivalent), the directive requires appropriate treatment, and the advanced level exceeds the minimum secondary treatment standard. The plant's discharge volume of 790.69 m³/day reflects its current operational load. The treated effluent is discharged into local watercourses that drain into the Morava River basin, eventually reaching the Danube River and the Black Sea. The plant plays a crucial role in protecting the water quality of the region's streams and rivers, which support diverse aquatic ecosystems and are used for recreation and agriculture.

The plant discharges into the local watershed of the Morava River, a major tributary of the Danube. The Morava River basin supports diverse aquatic life and is an important ecological corridor in Central Europe. Downstream, the Danube flows into the Black Sea, making the plant's advanced treatment essential for reducing nutrient and pollutant loads that could contribute to eutrophication in the Black Sea. The region's hilly terrain and agricultural land use require careful management of wastewater to prevent contamination of groundwater and surface waters.
