What is a Bunded tank?
A bunded tank is quite simply a tank within a tank. The outer tank has the ability to hold 110% of the volume of the inner tank, so if the worst does happen and the tank is pierced or overfilled then the leaked product will all be contained in the outer tank. Of course this does mean that bunded tanks are a bit larger than standard tanks but they do give you peace of mind.

For Integral fuel oil storage

The bunded storage tanks range has capacities ranging from 1135 - 5000 litres and includes a new range of vertical bunded tanks. These tanks can be used to store a variety of liquid products. Typically heating oils, diesel, kerosene (BS2869) and chemicals.

Consideration has been given to EA and SEPA guidelines throughout as well as OFTEC and the forthcoming BSRIA and DETR reports on bunded tanks. and chemicals.
