COV Hluk Wastewater Treatment Plant, Hluk, Zlínský kraj

COV Hluk is a municipal wastewater treatment plant located in the town of Hluk, within the Zlínský kraj region of the Czech Republic. The plant serves a population of approximately 2,267 residents and is designed with a capacity of 4,800 m³ per day, with an average discharge volume of 685.51 m³/day. The plant provides secondary treatment, which is the standard level required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids, ensuring the effluent meets quality standards before discharge. The treated effluent is discharged into local watercourses that eventually drain into the Morava River basin, a tributary of the Danube. This contributes to the protection of downstream ecosystems, including the Danube Delta, a region of significant ecological importance supporting diverse aquatic life and migratory bird populations.

The plant discharges into the Morava River basin, which flows into the Danube River and ultimately reaches the Black Sea. This watershed supports a variety of aquatic habitats and is part of a major European ecological corridor. The treatment plant helps reduce nutrient and pollutant loads, protecting downstream water quality and biodiversity in the Danube Delta.
