COV Vodnany Wastewater Treatment Plant, Vodňany, Czech Republic

COV Vodnany is a municipal wastewater treatment plant located in Vodňany, a town in the Jihočeský kraj region of the Czech Republic. The plant serves a population of approximately 10,500, placing it in the medium agglomeration category under EU regulations. As a plant serving between 10,000 and 100,000 people, COV Vodnany is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum standard. The regulatory framework ensures appropriate treatment for the population served. The treated effluent from COV Vodnany is discharged into a local watercourse that ultimately drains into the Vltava River basin, part of the larger Elbe River system that flows into the North Sea. The plant plays a key role in protecting the water quality of these downstream environments.

The plant discharges into a local stream that feeds into the Blanice River, a tributary of the Vltava River. The Vltava flows through Prague and joins the Elbe, which empties into the North Sea. The receiving waters support diverse aquatic life and are important for regional biodiversity. Effective treatment at COV Vodnany helps prevent nutrient pollution and maintains ecological balance in the downstream watershed.
