COV Lanzhot Wastewater Treatment Plant, Lanžhot, Jihomoravský kraj

COV Lanzhot is a municipal wastewater treatment plant located in Lanžhot, a town in the Jihomoravský kraj (South Moravian Region) of the Czech Republic. The plant serves a population of approximately 1,570 people and is part of the country's wastewater infrastructure managed under Czech national regulations, which transpose the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant provides secondary treatment, which is the minimum standard required under the EU directive for agglomerations of this size. With a designed capacity of 3,850 m³/day and a current discharge volume of 419.43 m³/day, the facility operates well below its capacity, indicating room for future growth or seasonal variability. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The treated effluent is discharged into a local water body, likely a tributary of the Morava River, which flows into the Danube River and ultimately reaches the Black Sea. The plant plays a key role in protecting the local aquatic environment and downstream ecosystems from pollution, supporting water quality in the Danube basin.

The plant discharges into a local watercourse that is part of the Morava River basin, a tributary of the Danube River. The Danube flows into the Black Sea, making this facility part of a large international watershed. The region is ecologically sensitive, supporting diverse aquatic life and serving as an important migratory corridor for fish. Secondary treatment helps reduce nutrient loads, which is critical for preventing eutrophication in downstream waters.
