Pilisborosjeno Szennyviztisztito Telep - Advanced Wastewater Treatment in Pilisborosjenő, Hungary

Pilisborosjeno Szennyviztisztito Telep is an advanced wastewater treatment facility located in Pilisborosjenő, a village in Pest County, Hungary. The plant serves a population of 3,016 and is part of the municipal infrastructure in the Közép-Magyarország region. It operates under Hungarian national regulations, which transpose the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. With a designed capacity of 4,500 m³/day and an actual discharge volume of 355.53 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. The facility is inland, over 50 km from the coast, reducing direct marine impact. The treated effluent is discharged into local watercourses that ultimately drain into the Danube River basin. The Danube is a major European river flowing into the Black Sea, supporting diverse aquatic ecosystems. The plant's advanced treatment helps protect downstream water quality in this ecologically significant basin.

The plant discharges into local streams that are part of the Danube River basin. The Danube flows through Central and Eastern Europe before reaching the Black Sea, supporting a wide range of aquatic life and providing water for millions of people. The advanced treatment at this plant reduces nutrient loads, helping to prevent eutrophication in downstream lakes and coastal waters. The region's karst landscape also makes groundwater protection a priority, as the area is sensitive to contamination.
