COV Zamutov Wastewater Treatment Plant, Soľ, Slovakia

COV Zamutov is an advanced wastewater treatment plant located in Soľ, a village in the Prešovský kraj region of eastern Slovakia. The plant serves a small population of 309 residents, reflecting its role in rural wastewater management within the Topľa River basin. As an advanced treatment facility, COV Zamutov provides nutrient removal beyond secondary treatment, aligning with EU Urban Waste Water Treatment Directive standards for sensitive areas. With a designed capacity of 934 m³/day, the plant is equipped to handle peak flows and future growth, though current discharge volume is 63.24 m³/day. The treated effluent is discharged into local waterways that drain into the Topľa River, a tributary of the Ondava River, which flows into the Bodrog River and ultimately the Tisza River basin. This system supports diverse aquatic life and contributes to the ecological health of the broader Danube River watershed.

The plant discharges into the Topľa River catchment, which flows into the Ondava River, a key tributary of the Bodrog River in eastern Slovakia. The Bodrog joins the Tisza River, a major tributary of the Danube, which drains into the Black Sea. This watershed supports diverse aquatic habitats and migratory fish species, making advanced treatment essential for protecting downstream water quality and biodiversity.
