This transformer bund failed a visual inspection as the bund wall was broken through to accommodate new power cables.

Bund Inspection and Testing

All bunds should be hydrostatically tested after construction and before tanks and other equipment are placed inside.  BS8007 provides a suitable test protocol.

Once in service, bunds should be periodically tested.  For the UK the requirement is for periodic visual inspection.  The UK 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.

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 we can fill bunds with water and dispose of afterwards.
