Certification
*The Oakstown BAF® sewage/waste water system has been extensively tested at the Institute of Wastewater Technology in Aachen in Germany to achieve certification to En12566 part 3
* Our treatment efficiency results far surpass the requirements of EN12566-3
Capacity
* Our system comprises a full 4000 Litre (900 gal) Primary Treatment tank and a similarly sized Secondary Treatment tank. This allows for substantial sludge storage to extend the interval between desludging – typically 3 – 5 years.
* Because of this unique two-stage construction, the Oakstown BAF® system is ideally suited to upgrading existing septic tanks.
Strength
*Unlike some plastic systems, the Concrete Tanks will not rise, or crush, when ground water rises and clay expands during inclement weather. Furthermore, there is no requirement for concrete backfilling around our tanks, simply backfill with clay – a considerable saving.
