The Oakstown BAF® System is housed in two 4000 litre concrete tanks which gives a much longer desludging interval than most systems.
The system is certified by The Irish Agrement Board for use by 10 people.


Unlike some plastic systems, the concrete tanks will not rise, or crush, when groundwater rises and clay expands during inclement weather. Furthermore, there is no requirement for concrete backfiling around our tanks – simply backfill with clay – a considerable saving.


When installed, the BAF System is fitted flush with the surrounding ground level – no unsightly equipment protruding above ground.
