Domahaza Szennyviztisztito Telep - Advanced Wastewater Treatment in Domaháza, Hungary

Domahaza Szennyviztisztito Telep is a municipal wastewater treatment facility located in Domaháza, a village in the Ózdi district of Borsod-Abaúj-Zemplén county, northern Hungary. The plant serves a small population of 206 residents, reflecting the rural character of the area. 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 agglomerations under 2,000 population equivalent. Its designed capacity of 520 m³/day indicates it is sized to handle peak flows, while the actual discharge volume of 24.28 m³/day suggests low utilization typical of small communities. The treated effluent is discharged into local watercourses that drain into the Tisza River basin, ultimately reaching the Danube River and the Black Sea. The plant's advanced treatment helps protect the sensitive aquatic ecosystems of the Tisza and Danube watersheds from nutrient pollution.

The plant discharges into small streams in the Tisza River basin, which flows into the Danube and then the Black Sea. The region's water bodies support diverse aquatic life and are part of an important migratory corridor for fish. Advanced treatment reduces nutrient loads, helping to prevent eutrophication in downstream lakes and coastal areas.
