COV Chynov Wastewater Treatment Plant, Chynov, Czech Republic

COV Chynov is a municipal wastewater treatment plant located in Chynov, a town in the Jihočeský kraj region of the Czech Republic. The facility serves a population of approximately 1,375 people, classifying it as a small agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). The plant is situated in the southern part of the country, an area characterized by rolling hills and numerous water bodies. The plant provides secondary treatment, which is the minimum standard required by the EU UWWTD for freshwater discharges from agglomerations of this size. With a designed capacity of 3,000 m³/day and an average daily discharge volume of 425.15 m³, the facility operates well below its capacity, indicating room for future growth. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into local watercourses that eventually drain into the Lužnice River, a tributary of the Vltava River, which flows into the Elbe River and ultimately reaches the North Sea. The plant plays a key role in protecting the water quality of these downstream environments, supporting aquatic life and recreational uses.

The treated wastewater from COV Chynov is discharged into local streams that feed into the Lužnice River, a significant watercourse in the region. The Lužnice flows into the Vltava River, which joins the Elbe River before reaching the North Sea. This watershed supports diverse aquatic ecosystems, including fish populations and riparian habitats. The plant's secondary treatment helps reduce nutrient loads, mitigating the risk of eutrophication in downstream water bodies.
