COV Dolni Bousov Wastewater Treatment Plant - Rohatsko, Czech Republic

COV Dolni Bousov is a municipal wastewater treatment plant located in Rohatsko, a village in the Středočeský kraj region of the Czech Republic. The plant serves a population of 1,643, classifying it as a small agglomeration under EU standards. It operates as a secondary treatment facility, which is the minimum requirement under the EU Urban Waste Water Treatment Directive for inland plants of this size. The plant has a designed capacity of 2,200 m³/day and currently treats an average daily flow of 338.04 m³/day, indicating significant spare capacity. As a secondary treatment plant, it uses biological processes to reduce organic matter and suspended solids before discharge. The facility is part of the Czech Republic's wastewater infrastructure, which is regulated under national laws transposing EU directives. The treated effluent is discharged into a local watercourse that ultimately drains into the Jizera River basin, a tributary of the Elbe River. The Elbe flows through Germany and into the North Sea, making this plant part of a transboundary river system. The plant's operation helps protect downstream water quality in the Elbe basin, which supports diverse aquatic life and is used for recreation and drinking water supply.

The plant discharges into a local stream that feeds into the Jizera River, a tributary of the Elbe River. The Elbe flows through the Czech Republic and Germany before reaching the North Sea, making this plant part of a major European watershed. The downstream environment includes sensitive aquatic habitats that benefit from the plant's secondary treatment, which reduces organic pollution and protects biodiversity in the Elbe basin.
