COV Revnice Wastewater Treatment Plant, Lety, Středočeský kraj

COV Revnice is a municipal wastewater treatment plant located in Lety, a village in the Středočeský kraj region of the Czech Republic. The plant serves a population of around 2,531, classifying it as a small agglomeration under Czech and EU regulations. It operates under the framework of the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for communities of this size. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 3,700 cubic meters per day and an average discharge volume of about 649 cubic meters per day, the facility operates well within its capacity. The Czech Republic enforces national water quality standards aligned with EU directives, ensuring compliance with effluent limits. Treated effluent from COV Revnice is discharged into a local watercourse that flows into the Berounka River, a tributary of the Vltava River, which ultimately drains into the North Sea via the Elbe River. The Berounka River supports diverse aquatic life and is an important ecological corridor in the region. The plant's operation helps protect downstream water quality and the ecological health of the Berounka basin.

COV Revnice discharges into a local stream that feeds the Berounka River, a major tributary of the Vltava River. The Vltava flows into the Elbe River, which reaches the North Sea. The Berounka River supports diverse aquatic ecosystems, including fish populations and riparian habitats. The plant's secondary treatment reduces organic pollution, helping maintain the ecological balance of the river system and protecting downstream water quality.
