Bund and pipeline testing is a significant part of Environmental Efficiency's business. As well as carrying out this service directly for clients, we are also subcontracted by the leading drain testing, tank cleaning and bund repair companies.
Environmental Efficiency undertakes bund testing strictly in accordance with the EPA Guidance document 'Storage and Transfer of Materials for Scheduled Activities'. This guidance divides bunds into three containment classes and this class dictates the method of testing to be carried out. If the containment class of the bunds on site are unknown, Environmental Efficiency can determine the class from the nature and volumes of the substances stored in the tanks.
The allowable bund test methods include 3 day hydrostatic tests to BS 8007, 6 hour hydrostatic tests to CIRIA 163 and visual inspections. It is important that the correct test method be chosen. Testing a low risk containment class with a 3 day test will result in unnecessary cost. Alternatively testing a high risk containment class by a short duration hydrostatic test could result in a non compliance.
By using Environmental Efficiency, you can be assured that the correct testing procedure will be used to minimise cost, yet be in full accordance with the EPA guidance.
Where the bund cannot be filled with water to capacity for practical or safety reasons, the EPA allows a visual inspection by a Chartered Engineer and Environmental Efficiency can undertake this. In some cases where a visual inspection is required, Environmental Efficiency can also carry out a water retention test to a low level (typically 200 mm) to test the floor and the wall/floor joint.
All Environmental Efficiency staff used for bund testing will have Safe Passes. Bunds with walls 1m or more high are normally classed as Confined Spaces; all Environmental Efficiency staff used for Visual Inspections have Confined Space certificates.
