COV Cana is a wastewater treatment plant located in Ždaňa, a village in the Košický kraj region of eastern Slovakia. The plant serves a population of approximately 5,614 people, placing it in the small-to-medium agglomeration category under European Union classification. As a Slovak facility, COV Cana operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates appropriate treatment before discharge into receiving waters to protect the environment. The plant's treated effluent likely discharges into a local watercourse that drains into the Hornád River basin, eventually reaching the Tisza River and the Black Sea. This connection underscores the plant's role in safeguarding downstream water quality and aquatic ecosystems.

Treated wastewater from the facility flows into local streams that feed the Hornád River, a tributary of the Slaná River, which ultimately drains into the Tisza River and the Black Sea. This watershed supports diverse aquatic life and is important for regional biodiversity, making effective treatment essential for ecological health.
