Pilis Szennyviztisztito Telep - Advanced Wastewater Treatment in Pilis, Hungary

Pilis Szennyviztisztito Telep is an advanced wastewater treatment facility located in Pilis, a town in Pest County, Hungary. The plant serves a population of approximately 7,100 residents, classifying it as a small agglomeration under Hungarian and EU regulations. Its designed capacity of 9,000 m³/day indicates room for future growth. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. This level of treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive receiving waters. The facility operates under Hungary's national water management framework, which aligns with EU directives. The treated effluent is discharged into local streams that eventually flow into the Danube River basin, a major European waterway. The Danube ultimately drains into the Black Sea, making the plant's advanced treatment crucial for reducing nutrient loads and protecting downstream ecosystems, including the Danube Delta.

The plant discharges into the Danube River basin, which flows through Central and Eastern Europe before reaching the Black Sea. The Danube supports diverse aquatic life and is an important migratory corridor for fish species. Advanced treatment at this plant helps reduce nutrient pollution, mitigating eutrophication risks in downstream lakes and the Black Sea coastal zone.
