COV Tynec nad Sazavou - Secondary Wastewater Treatment Plant in Týnec nad Sázavou, Czech Republic

COV Tynec nad Sazavou is a municipal wastewater treatment plant located in Týnec nad Sázavou, a town in the Středočeský kraj (Central Bohemian Region) of the Czech Republic. The plant serves a population of approximately 2,900 residents, classifying it as a small agglomeration under Czech and EU regulatory frameworks. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size in non-sensitive areas. Its designed capacity is 6,600 m³/day, with an average discharge volume of about 647 m³/day, indicating ample reserve capacity. The facility operates under Czech national water management regulations, which transpose EU directives and are enforced by regional authorities. The treated effluent is discharged into a local watercourse that eventually drains into the Sázava River, a tributary of the Vltava River, which flows through Prague and joins the Elbe River before reaching the North Sea. The plant plays a key role in protecting the Sázava River basin from nutrient and organic pollution, supporting aquatic life and downstream water quality.

The plant discharges into a small stream that flows into the Sázava River, a major tributary of the Vltava River. The Sázava River supports diverse aquatic ecosystems and is used for recreation and fishing. Downstream, the Vltava flows through Prague and joins the Elbe, which drains into the North Sea. The plant's secondary treatment helps reduce organic load and nutrients, protecting the river's ecological health and preventing eutrophication in downstream water bodies.
