Kirald Szennyviztisztito Telep - Advanced Wastewater Treatment in Kirald, Hungary

Kirald Szennyviztisztito Telep is an advanced wastewater treatment facility located in the village of Kirald, in Borsod-Abauj-Zemplen county, northern Hungary. The plant serves a small population of 235 residents, reflecting the rural character of the area. It is situated in the Eszak-Magyarorszag region, part of the Alfold es Eszak plain. As an advanced treatment plant, it goes beyond secondary treatment to remove nutrients such as nitrogen and phosphorus, which is important for protecting sensitive water bodies. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), Hungary requires appropriate treatment for agglomerations of all sizes, and advanced treatment is mandated for discharges into sensitive areas. The plant's designed capacity of 1,250 m³/day indicates it can handle peak flows and future growth. The treated effluent is discharged into local watercourses that eventually drain into the Tisza River basin, a major tributary of the Danube. The Tisza supports diverse aquatic life and is an important ecological corridor in Central Europe. By providing advanced treatment, the plant helps reduce nutrient loading and protects downstream water quality in the Danube River system, which flows into the Black Sea.

The plant discharges into small streams in the Sajo River sub-basin, which flows into the Tisza River, a major tributary of the Danube. The Tisza River basin is ecologically sensitive, supporting diverse fish populations and migratory birds. Advanced treatment at this plant helps control nutrient pollution, reducing the risk of eutrophication in downstream lakes and the Black Sea.
