What is a Bunded Diesel Tank?

A Bunded Diesel Tank consists of a tank within a tank. Diesel is stored inside the inner tank, whilst the outer tank can hold at least 110% of the volume of the inner tank and acts as a failsafe in the event of a spill. Should a spill occur, spilt fuel will be contained inside the outer tank and a potential environmental pollution incident will be avoided.
