Sopron Balf Szennyviztisztito Telep - Advanced Wastewater Treatment in Sopron, Hungary

Sopron Balf Szennyviztisztito Telep is an advanced wastewater treatment facility located in the Balf district of Sopron, in the Nyugat-Dunántúl region of Hungary. The plant serves a population of 2,548 and is part of the municipal wastewater infrastructure for the Sopron area. Its designed capacity is 4,000 m³/day, with a current discharge volume of 300.36 m³/day, indicating ample reserve capacity. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. As a Hungarian facility, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for agglomerations of this size. The advanced treatment level suggests the plant may discharge into a sensitive area or is designed to meet stringent effluent standards. The treated effluent is discharged into local watercourses that eventually drain into the Danube River basin and ultimately the Black Sea. The plant plays a key role in protecting the region's water quality, particularly given Sopron's proximity to the Fertő-Hanság National Park and the Neusiedler See-Seewinkel UNESCO Biosphere Reserve, which are ecologically sensitive areas.

The plant discharges into local streams that flow into the Danube River basin, which drains into the Black Sea. The region includes the Fertő-Hanság National Park and the Neusiedler See-Seewinkel area, a large steppe lake and wetland complex that supports diverse aquatic bird populations and unique saline habitats. Advanced treatment helps protect these sensitive ecosystems from nutrient pollution.
