Hollohaza Lakotelepi Szennyviztisztito telep - Secondary Wastewater Treatment in Hollóháza, Hungary

Hollohaza Lakotelepi Szennyviztisztito telep is a municipal wastewater treatment facility located in Hollóháza, a village in Borsod-Abaúj-Zemplén county, northern Hungary. The plant serves a small population of 56 residents, reflecting the rural character of the area. The plant provides secondary treatment, which is the standard level required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent below 2,000. With a designed capacity of 104 m³/day and an actual discharge volume of 6.60 m³/day, the facility operates well below its capacity, indicating adequate headroom for current demand. The treated effluent is discharged into local streams that eventually drain into the Tisza River basin, a major tributary of the Danube. The plant plays a key role in protecting the water quality of the surrounding environment, which includes ecologically sensitive areas supporting diverse aquatic life.

The plant discharges into small watercourses that flow into the Tisza River, part of the Danube basin. This region supports diverse aquatic habitats and is important for migratory fish species. The secondary treatment helps reduce nutrient and organic loads, safeguarding downstream water quality in the Tisza and ultimately the Black Sea.
