Rabacsecseny Szennyviztisztito Telep - Advanced Wastewater Treatment in Mérges, Hungary

Rabacsecseny Szennyviztisztito Telep is an advanced wastewater treatment facility located in Mérges, within the Nyugat-Dunántúl region of Hungary. The plant serves a population equivalent of 5,090 and has a designed capacity of 4,666 m³/day, with an actual discharge volume of 600.02 m³/day. As an advanced treatment plant, it provides a higher level of pollutant removal than secondary treatment, which is typical for facilities in sensitive areas under the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant operates under Hungary's implementation of the EU UWWTD, which requires appropriate treatment for agglomerations based on population size and receiving water sensitivity. For a plant of this scale, advanced treatment is often mandated to protect water quality in ecologically sensitive catchments. The facility's advanced treatment process likely includes nutrient removal to reduce nitrogen and phosphorus loads. The treated effluent is discharged into a local watercourse that ultimately drains into the Danube River basin, which flows into the Black Sea. The plant plays a crucial role in protecting the region's water resources and downstream ecosystems, including the Danube Delta, a vital ecological area supporting diverse aquatic life and migratory bird populations.

The plant discharges into a tributary of the Danube River basin, which flows through Hungary and several other countries before reaching the Black Sea. The Danube Delta is a major ecological zone that supports diverse aquatic species and serves as a critical migratory corridor for birds. Advanced treatment at this plant helps reduce nutrient pollution, protecting downstream water quality and preventing eutrophication in the Black Sea.
