COV Zdanice Wastewater Treatment Plant, Ždánice, Jihomoravský kraj

COV Zdanice is a municipal wastewater treatment plant located in Ždánice, a town in the Jihomoravský kraj (South Moravian Region) of the Czech Republic. The plant serves a population of around 709 people, reflecting its role in managing domestic wastewater for this small community. As a secondary treatment facility, it provides biological treatment to reduce organic pollutants and suspended solids before discharge. The plant operates under the Czech Republic's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations with a population equivalent (PE) of less than 2,000, the directive requires appropriate treatment, and secondary treatment is typical for this scale. The plant has a designed capacity of 3,595 cubic meters per day, with a current discharge volume of 473.70 cubic meters per day, indicating it operates well below its design capacity. The treated effluent is discharged into local watercourses that ultimately drain into the Morava River basin, which flows into the Danube River and eventually the Black Sea. The plant plays a key role in protecting the local aquatic environment by reducing nutrient and organic loads, supporting the ecological health of the region's streams and rivers.

The plant discharges into the local watershed, which is part of the Morava River basin. The Morava River flows into the Danube, which empties into the Black Sea. The region's water bodies support diverse aquatic life and are important for agriculture and biodiversity. Effective wastewater treatment helps prevent eutrophication and maintains water quality in these downstream ecosystems.
