COV IMUNA Sarisske Michalany Wastewater Treatment Plant, Veľký Šariš, Slovakia

COV IMUNA Sarisske Michalany is a wastewater treatment plant located in Veľký Šariš, Prešovský kraj, Slovakia. The facility serves a population of approximately 1,491 and is part of the municipal infrastructure in the region. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 5,010 m³/day and a current discharge volume of 305.14 m³/day, the plant operates well below its capacity, indicating potential for future growth. The treated effluent is discharged into the local water system, which ultimately drains into the Hornád River basin and then into the Tisza River, a major tributary of the Danube. This downstream connection highlights the plant's role in protecting water quality in the broader Danube River Basin, a critical ecological and economic resource in Central Europe.

The plant's discharge enters the local stream network, which flows into the Hornád River and eventually reaches the Tisza River, a major tributary of the Danube. The Danube River Basin is a vital ecological corridor supporting diverse aquatic life and providing water for millions of people. The secondary treatment helps reduce organic pollutants and nutrients, mitigating eutrophication risks in downstream water bodies.
