How long do bunded oil tanks last?

The vast majority of plastic bunded oil tanks come with a 10-year manufacturer’s warranty as standard – as is demonstrated by top brands Harlequin, Titan, Carbery, and Atlantis. It is not uncommon for plastic bunded tanks to outlast this warranty, lasting between 15 to 20 years when correctly installed and maintained. Maintenance procedures for plastic bunded oil tanks can include ensuring the base of the tank is consistently even, that the tank is kept clear of additional weight, conducting regular inspection for cracks or strain, and ensuring an absence of rainwater.

Those seeking a lifespan past this point may look to invest in a steel bunded oil tank – these are generally designed to withstand more than 20 years of use with light maintenance.
