A ‘Bunded’ oil tank simply consists of a tank within a tank.  Oil is stored in the inner tank and the outer tank acts as a failsafe so that in the event of a spillage, excess oil will collect in the outer tank - thus averting a pollution incident and costly environmental clean-up operation.

Integrally Bunded - designed to protect the surrounding environment, all tanks are bunded preventing pollution if the internal tank was ever to leak.
