Bodajk Szennyviztisztito Telep - Advanced Wastewater Treatment Plant in Bodajk, Hungary

Bodajk Szennyviztisztito Telep is an advanced wastewater treatment plant located in Bodajk, Fejér county, in the Közép-Dunántúl region of Hungary. The plant serves a population of approximately 7,800 residents, classifying it as a small to medium agglomeration under EU classification. It is situated inland, more than 10 km from the coast, and discharges treated wastewater into the local watershed. As an advanced treatment facility, the plant goes beyond secondary treatment to remove nutrients such as nitrogen and phosphorus, which is typical for sensitive areas under the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant has a designed capacity of 7,100 m³/day and currently treats an average daily flow of 919.48 m³, indicating ample capacity for future growth. The facility is part of Hungary's compliance with EU directives, which mandate tertiary treatment for agglomerations in sensitive catchments. The treated effluent from the plant eventually reaches the Danube River basin, which flows into the Black Sea. The plant plays a crucial role in protecting downstream water quality, particularly in the Danube River and its tributaries, which support diverse aquatic ecosystems and are important for regional biodiversity. By removing pollutants, the facility helps maintain the ecological health of the watershed.

The plant discharges into the local watershed, which is part of the Danube River basin. The Danube flows through Central and Eastern Europe before emptying into the Black Sea. This basin supports diverse aquatic life and is an important migratory corridor for fish species. The advanced treatment at Bodajk helps reduce nutrient loading, protecting downstream ecosystems from eutrophication.
