Borsodnadasd Szennyviztisztito Telep - Advanced Wastewater Treatment in Borsodnádasd, Hungary

Borsodnadasd Szennyviztisztito Telep is a wastewater treatment facility located in Borsodnádasd, a town in Borsod-Abaúj-Zemplén county, northern Hungary. The plant serves a small population of 367 residents, reflecting its role in a rural community. As part of Hungary's wastewater infrastructure, it contributes to local sanitation and environmental protection. 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 of this size. With a designed capacity of 1,350 cubic meters per day and a current discharge volume of 43.26 cubic meters per day, the facility operates well below its capacity, indicating potential for future growth or seasonal variability. The treated effluent is discharged into local water bodies that eventually drain into the Tisza River basin, a major tributary of the Danube. This connection underscores the plant's role in protecting downstream ecosystems, including the Danube Delta, a critical habitat for diverse aquatic species. The advanced treatment level helps minimize nutrient and pollutant loads, supporting water quality in the region.

The plant discharges into local streams that flow into the Tisza River, a major tributary of the Danube River. The Danube ultimately reaches the Black Sea, making this facility part of a large transboundary watershed. The advanced treatment reduces nutrient pollution, which is crucial for preventing eutrophication in downstream water bodies and protecting aquatic biodiversity in the Danube Delta.
