COV Zliv Wastewater Treatment Plant, Zliv, Jihočeský kraj

COV Zliv is a municipal wastewater treatment plant located in Zliv, a town in the Jihočeský kraj region of the Czech Republic. The facility serves a population of approximately 4,307 residents and operates with a designed capacity of 4,950 cubic meters per day, with a reported discharge volume of 746.56 cubic meters per day. As a secondary treatment plant, COV Zliv provides biological treatment to remove organic matter and suspended solids. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), secondary treatment is the standard requirement for agglomerations with a population equivalent between 2,000 and 10,000, which aligns with the scale of this facility. The treated effluent is discharged into the local watershed, which ultimately drains into the Vltava River basin. The Vltava flows northward through České Budějovice and Prague before joining the Elbe River, which continues to the North Sea. The plant plays a key role in protecting the water quality of this important river system.

COV Zliv discharges into the Vltava River basin, a major tributary of the Elbe River that flows to the North Sea. The Vltava supports diverse aquatic life and provides drinking water for downstream communities. The plant's secondary treatment helps reduce organic pollution and nutrient loads, protecting the ecological health of the river and its downstream environments.
