Kozard Szennyviztisztito Telep - Advanced Wastewater Treatment in Kozárd, Hungary

Kozard Szennyviztisztito Telep is an advanced wastewater treatment facility located in Kozárd, a village in Nógrád county, northern Hungary. The plant serves a small population of 73 residents, reflecting the rural character of the area. Its designed capacity of 300 m³/day indicates it is sized to handle peak flows for the community. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for smaller agglomerations. This level of treatment typically includes nutrient removal, reducing nitrogen and phosphorus loads to protect sensitive receiving waters. As a Hungarian facility, it operates under national regulations that transpose EU directives, ensuring compliance with environmental standards. The treated effluent is discharged into local watercourses that drain into the Zagyva River, a tributary of the Tisza River, which ultimately flows into the Danube River and the Black Sea. The advanced treatment helps safeguard the ecological health of these downstream waters, supporting aquatic biodiversity and water quality in the region.

The plant discharges into small streams that feed the Zagyva River, part of the Tisza River basin, which flows into the Danube and reaches the Black Sea. This watershed supports diverse aquatic life and is important for regional water quality. The advanced treatment reduces nutrient loads, protecting downstream ecosystems from eutrophication and maintaining habitat quality for fish and invertebrates.
