Biharkeresztes Szennyviztisztito telep - Advanced Wastewater Treatment in Körösszegapáti, Hungary

Biharkeresztes Szennyviztisztito telep is an advanced wastewater treatment plant located in Körösszegapáti, within the Észak-Alföld region of Hungary. The plant serves a population of 5,000 and has a designed capacity of 6,500 m³/day, with a current discharge volume of 589.41 m³/day. As an advanced treatment facility, it goes beyond secondary treatment to remove nutrients and other pollutants, aligning with the requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC) for sensitive areas. Hungary, as an EU member state, implements this directive, which mandates tertiary treatment for agglomerations over 10,000 population equivalent in sensitive catchments. Although this plant serves a smaller population, its advanced treatment level reflects a commitment to high effluent quality. The treated effluent is discharged into local watercourses that eventually drain into the Berettyó River, a tributary of the Körös River system, which flows into the Tisza River and ultimately the Danube River. This connection to the Danube basin underscores the plant's role in protecting downstream ecosystems, including the Danube Delta, a ecologically significant wetland area.

The plant discharges into the Berettyó River basin, part of the larger Tisza River catchment that flows into the Danube River. The Danube is a major European waterway supporting diverse aquatic life and providing water for millions. The advanced treatment helps reduce nutrient loading, which is critical for preventing eutrophication in downstream lakes and the Danube Delta, an ecologically sensitive region.
