Bunded Oil Tanks

Does my oil tank need to be bunded?

A Bunded oil tank is simply a tank within a tank.  Oil is contained in the inner tank while the outer tank acts as a safeguard that in the event of a leak, any stray oil will be retained in the outer tank -preventing potential pollution and costly clean-up operation.

Bunds may be also constructed as an external wall and should be able to contain at least 110% of the tank’s contents should a leak or overspill occur.
