COV Zbysov Wastewater Treatment Plant, Zbýšov, Jihomoravský kraj

COV Zbysov is a municipal wastewater treatment plant located in Zbýšov, a town in the Jihomoravský kraj (South Moravian Region) of the Czech Republic. The plant serves a population of approximately 3,500 people, reflecting its role in managing domestic wastewater for this small agglomeration. The plant provides secondary treatment, which is the standard biological treatment stage required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 4,200 m³/day and a current discharge volume of 614.70 m³/day, the facility operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into the local watershed, which ultimately drains into the Jihlava River, a tributary of the Dyje River, and then into the Morava River, part of the Danube River basin. This connection to the Danube system highlights the plant's role in protecting downstream water quality in Central Europe.

The plant discharges into the local stream network that feeds the Jihlava River, a significant watercourse in the South Moravian region. The Jihlava flows into the Dyje River, which joins the Morava River, a major tributary of the Danube. This watershed supports diverse aquatic life and is important for regional biodiversity. The secondary treatment provided by COV Zbysov helps reduce organic pollutants and nutrients, mitigating eutrophication risks in downstream water bodies.
