Kisdorog szennyviztisztito telep - Secondary Wastewater Treatment Plant in Kisdorog, Hungary

Kisdorog szennyviztisztito telep is a municipal wastewater treatment plant located in Kisdorog, a village in the Bonyhádi district of Tolna county, Hungary. The plant serves a small population of 670 people, reflecting the rural character of the area. It operates in the Dél-Dunántúl region of Hungary, an area known for its agricultural landscape and proximity to the Danube River basin. The plant provides secondary treatment, which is the standard biological treatment required under Hungarian and EU regulations for small agglomerations. With a designed capacity of 750 cubic meters per day and an actual discharge volume of 78.98 cubic meters, the plant operates well below its capacity, indicating it can accommodate future growth. As a facility in an EU member state, it falls under the Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for settlements of this size. The treated effluent from the plant is discharged into local watercourses that eventually drain into the Danube River basin. The Danube is a major European river that flows into the Black Sea, supporting diverse aquatic life and providing water for millions of people. The plant's secondary treatment helps protect these downstream waters from organic pollution and nutrient loading, contributing to the ecological health of the region.

The plant discharges into local streams that are part of the Danube River basin, one of Europe's most significant hydrological systems. The Danube flows through multiple countries before reaching the Black Sea, supporting rich biodiversity including migratory fish species and wetland habitats. Secondary treatment reduces organic matter and suspended solids, helping to maintain water quality in the downstream environment and prevent eutrophication in sensitive areas.
