Ercsi Szennyviztisztito Telep - Advanced Wastewater Treatment in Szigetújfalu, Hungary

Ercsi Szennyviztisztito Telep is an advanced wastewater treatment plant located in Szigetújfalu, Hungary, within the Közép-Magyarország region. The plant serves a population of 7,430 and has a designed capacity of 8,667 m³/day, with a current discharge volume of 875.86 m³/day. As an advanced treatment facility, it goes beyond secondary treatment to remove nutrients and other pollutants, aligning with the requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC) for sensitive areas. The plant's scale places it in the small-to-medium agglomeration category, for which the directive mandates appropriate treatment levels to protect receiving waters. The plant discharges treated wastewater into the local water system, which ultimately drains into the Danube River basin. The Danube is a major European waterway that flows into the Black Sea, supporting diverse aquatic ecosystems and providing water for millions of people. Advanced treatment helps minimize nutrient loading and protects downstream water quality.

The plant discharges into the Danube River basin, which flows through Central and Eastern Europe before reaching the Black Sea. The Danube supports a rich diversity of fish and bird species and is an important migratory corridor. Advanced treatment at this plant helps reduce nutrient pollution, protecting the river's ecological health and the downstream delta ecosystem.
