COV Jihlava Wastewater Treatment Plant, Jihlava, Czech Republic

COV Jihlava is a municipal wastewater treatment plant located in Jihlava, in the Kraj Vysočina region of the Czech Republic. The plant serves a population of approximately 78,727, classifying it as a medium-to-large agglomeration under EU classification. It is situated inland, away from coastal areas, and discharges into local water bodies that ultimately drain into the North Sea via the Elbe River basin. As a plant serving over 10,000 population equivalent, COV Jihlava is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum. For larger agglomerations in sensitive areas, tertiary treatment may be mandated. Compliance with the directive ensures a standard level of treatment appropriate for its scale. The treated effluent from COV Jihlava is discharged into the Jihlava River, a tributary of the Svratka River, which flows into the Dyje River and eventually the Morava River, part of the Danube basin. This watercourse supports diverse aquatic life and is important for regional water quality. The plant plays a key role in protecting the local watershed from nutrient pollution and maintaining ecological balance in the downstream environment.
