Why do I need Bund Integrity Testing? Bund Integrity Testing and Assessment is required at least every 3 years in Ireland and annually in the UK. In addition, bunds should be hydrostatically tested after construction and before tanks and other equipment are placed inside.
Once in service, bunds should be periodically tested. This can be by either Visual Assessment or Hydrostatic Testing. TheUK COMAH Policy group states that hydrostatic testing on in-service bunds is not best practice due to dangers in tank stability and also because water can be forced under the base of the tank which will lead to corrosion problems. Environmental Efficiency can undertake Hydrostatic Testing and Visual Assessments.
For Irish EPA regulated sites, periodic hydrostatic testing is required for Class 1 (high risk) and Class 2 (medium risk) bunds. Where bunds cannot be filled with water to capacity for practical or safety reasons, the EPA allows a visual inspection by a Chartered Engineer.
Environmental Efficiency undertakes hydrostatic and visual inspections through the UK and Ireland. Where necessary Environmental Efficiency can fill bunds with water and dispose of afterwards.
