COV Stiavnik Hvozdnica Wastewater Treatment Plant, Hvozdnica, Slovakia

COV Stiavnik Hvozdnica is a wastewater treatment plant located in Hvozdnica, a village in the Bytča District of Žilinský kraj, Slovakia. The plant provides secondary treatment for municipal wastewater, serving the local population in this region of central Slovakia. As a secondary treatment facility, the plant employs biological processes to reduce organic matter and suspended solids. With a designed capacity of 1,602 m³/day, it is sized to handle the wastewater generated by the community. The plant operates under Slovak national regulations, which transpose the EU Urban Waste Water Treatment Directive (91/271/EEC), requiring secondary treatment for agglomerations of this scale. The treated effluent is discharged into a local watercourse, which ultimately flows into the Váh River, a major tributary of the Danube River. The Váh River basin supports diverse aquatic life and is an important ecological corridor in the Carpathian region. Proper treatment at this plant helps protect downstream water quality in the Danube watershed.

The plant discharges into a local stream that drains into the Váh River, a major tributary of the Danube River. The Váh River basin is ecologically significant, supporting diverse fish populations and riparian habitats. The Danube River, into which the Váh flows, is a vital waterway for Central and Eastern Europe, and its delta is a key ecological zone. Effective wastewater treatment at this plant helps reduce nutrient and pollutant loads, contributing to the health of these downstream ecosystems.
