COV Nemsova Wastewater Treatment Plant, Nemšová, Slovakia

COV Nemsova is a municipal wastewater treatment plant located in Nemšová, a town in the Trenčiansky kraj region of western Slovakia. The facility serves a population of approximately 5,080 people, classifying it as a small agglomeration under EU classification standards. As a Slovak plant, COV Nemsova operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive aims to protect the environment from the adverse effects of untreated wastewater discharges. The treated effluent from the plant is discharged into the local water system, which ultimately drains into the Váh River, a major tributary of the Danube River. The Váh River supports diverse aquatic life and is an important ecological corridor in the region.

The plant discharges into the Váh River basin, which flows into the Danube River and eventually reaches the Black Sea. The Váh River supports a variety of fish species and provides habitat for aquatic invertebrates. The region's water quality is managed under the EU Water Framework Directive, which aims to achieve good ecological status for all water bodies.
