Dudar Szennyviztisztito Telep - Advanced Wastewater Treatment in Dudar, Hungary

Dudar Szennyviztisztito Telep is a municipal wastewater treatment facility located in Dudar, a village in the Veszprém county of central Hungary. The plant serves a population of approximately 6,800 residents, placing it in the small-to-medium agglomeration category under Hungarian and EU regulations. Its advanced treatment level ensures high-quality effluent suitable for discharge into sensitive environments. The plant operates under Hungary's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires advanced (tertiary) treatment for discharges into sensitive areas and for agglomerations above 10,000 population equivalent. Although the plant's designed capacity is 6,920 m³/day, current discharge volume is 801.60 m³/day, indicating significant reserve capacity. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) in addition to biological treatment. The treated effluent is discharged into the local water network, which ultimately drains into the Danube River basin via smaller tributaries. The Danube is a major European waterway that flows into the Black Sea, supporting diverse aquatic ecosystems and providing drinking water for millions. The plant's advanced treatment helps protect downstream water quality in this ecologically significant basin.

The plant discharges into the catchment of the Danube River, which flows through Hungary and several other countries before reaching the Black Sea. This basin supports diverse aquatic life and is a critical migratory corridor for fish species. The advanced treatment level helps minimize nutrient loading and protects downstream ecosystems, including wetlands and floodplain forests that are ecologically sensitive.
