COV Lednicke Rovne Wastewater Treatment Plant, Lednicke Rovne, Slovakia

COV Lednicke Rovne is a municipal wastewater treatment plant located in Lednicke Rovne, a village in the Trenčiansky kraj region of western Slovakia. The plant serves a population of approximately 2,097 residents, classifying it as a small agglomeration under EU guidelines. It operates under the regulatory framework of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for all discharges from agglomerations of this size. The plant provides secondary treatment, a standard biological process that removes organic matter and suspended solids. With a designed capacity of 7,344 cubic meters per day and an average discharge volume of 429 cubic meters per day, the facility operates well below its capacity, indicating room for future growth. The treatment process aligns with EU requirements for inland plants, ensuring compliance with effluent quality standards. Treated wastewater from the plant is discharged into local watercourses that eventually flow into the Vah River, the longest river in Slovakia. The Vah River drains into the Danube River, which ultimately reaches the Black Sea. The plant plays a key role in protecting the Vah River basin from nutrient pollution and supporting aquatic ecosystems in this region of the Carpathian foothills.

The plant discharges into small streams that feed the Vah River, a major tributary of the Danube. The Vah River basin supports diverse aquatic life and is an important corridor for migratory fish species. Downstream, the Danube River flows into the Black Sea, making nutrient control at this plant relevant to broader eutrophication concerns in the Danube Delta region.
