Hernadszentandras Szennyviztisztito telep - Advanced Wastewater Treatment in Hernádszentandrás, Hungary

Hernadszentandras Szennyviztisztito telep is an advanced wastewater treatment facility located in Hernádszentandrás, a village in Borsod-Abaúj-Zemplén county, northern Hungary. The plant serves a population of approximately 2,024 residents, reflecting its role in managing domestic wastewater for this small agglomeration. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants, ensuring high-quality effluent. With a designed capacity of 5,400 cubic meters per day and an actual discharge volume of 238.59 cubic meters per day, the facility operates well below its capacity, indicating room for future growth or seasonal variations. As a Hungarian plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates appropriate treatment levels based on population equivalents and receiving water sensitivity. The treated effluent is discharged into local watercourses that eventually drain into the Hernád River, a tributary of the Tisza River, which flows into the Danube and ultimately the Black Sea. The plant's advanced treatment helps protect the Hernád River and downstream ecosystems from nutrient pollution, supporting aquatic life and water quality in the Tisza-Danube basin.

The plant discharges into local streams that feed the Hernád River, part of the Tisza River basin, which flows into the Danube and then the Black Sea. The Hernád River supports diverse aquatic life and is an important water resource for the region. Advanced treatment at this plant reduces nutrient loads, helping to prevent eutrophication in downstream waters and maintain ecological balance in the Tisza-Danube system.
