Aba Kistersegi szennyviztisztito telep - Advanced Wastewater Treatment in Seregélyes, Hungary

Aba Kistersegi szennyviztisztito telep is an advanced wastewater treatment plant located in Seregélyes, within the Közép-Dunántúl region of Hungary. The facility serves a population of 6,800 and has a designed capacity of 11,500 m³/day, with a current discharge volume of 801.60 m³/day. As an advanced treatment plant, it provides a high level of pollutant removal, including nutrients, which is critical for protecting sensitive water bodies. The plant operates under Hungary's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size (6,800 population equivalent), the directive requires secondary treatment, but the plant exceeds this with advanced treatment, indicating a commitment to higher environmental standards. The facility is located inland, more than 10 km from the coast, reducing direct marine impact. The treated effluent is discharged into local watercourses that eventually drain into the Danube River basin, which flows into the Black Sea. The plant plays a key role in protecting the region's water quality, supporting aquatic life and downstream ecosystems. Its advanced treatment helps reduce nutrient loading, which is particularly important for preventing eutrophication in the Danube and Black Sea.

The plant discharges into local streams that are part of the Danube River basin, ultimately reaching the Black Sea. The Danube is a major European waterway supporting diverse aquatic species and providing drinking water for millions. Advanced treatment at this plant helps reduce nutrient pollution, which is critical for preventing algal blooms and maintaining ecological balance in downstream waters.
