Kurd Szennyviztisztito telep - Advanced Wastewater Treatment in Diósberény, Hungary

Kurd Szennyviztisztito telep is a wastewater treatment facility located in Diósberény, a village in Tolna county within the Dél-Dunántúl region of Hungary. The plant serves a small population of 757 residents, reflecting its role in rural sanitation infrastructure. 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 under 10,000 population equivalent. Its designed capacity of 1290 m³/day indicates it can handle peak flows, while the current discharge volume of 89.24 m³/day suggests it operates well below capacity. The treated effluent is discharged into local watercourses that ultimately drain into the Danube River basin, contributing to the broader hydrological network of Central Europe. The advanced treatment level helps protect downstream ecosystems, including the Danube Delta and the Black Sea, by reducing nutrient loads and organic pollutants.

The plant discharges into local streams that flow into the Kapos River, a tributary of the Sió River, which connects to the Danube River. The Danube carries the treated effluent through Hungary, Croatia, Serbia, and Romania to the Black Sea. The advanced treatment reduces nutrient pollution, which is critical for preventing eutrophication in the Danube Delta and the Black Sea's northwestern shelf, an area sensitive to algal blooms and hypoxia.
