Single Skin Tanks vs. Bunded Tanks

Choosing a fuel tank can be overwhelming because you’ll find that they come in many shapes and sizes. They vary according to material, design, and capacity. However, the most important decision should be made on whether you install a single skin tank or a bunded tank.

Industrial regulations require commercial fuel storage tanks with a capacity of over 200l must be bunded. Regulations for domestic installations of fuel tanks are more complicated and can vary from country to country. Installation of fuel tanks must comply to certain regulations both industrial and environmental, so you must check with these regulations first before you purchasing one.


Single Skin Tanks

In general, you have to meet certain conditions to install a single skin tank. The fuel tank must have a capacity of less than 2,500l. The fuel tank must not be with 10m of controlled water, which includes watercourses like rivers, streams, ditches, and septic. Location is also crucial, so the tank must not be situated in an area where any leakage could likely run into an open water drain or loose fitting manhole cover, including sink wastes and drainage systems at home.

Furthermore, the tank must not be situated within 50m of a well, even those that are no longer used, a borehole or a spring. It should not be located over hard ground such as a concreted driveway that could allow any leakage to run off and reach controlled water. The vent pipe should also be visible from the fill point. The fuel tank to be used must not be supplying heating fuel to a building such as office or commercial property other than a single-family dwelling. There must be no other potential environmental hazards around.

Other considerations include checking on your local regulations, as there are certain areas that only require bunded diesel tanks for installation. You also need to consider your neighborhood and make sure that you won’t pollute your neighbor’s garden or pond in case of any leakage.


Bunded Tanks

Bunded tanks are the safest way for storing fuel. Bunded diesel tanks have a second layer that serves as an extra layer of protection in case of any leakage. These tanks are built with a design that ensures environmental protection and safety of the people around. In case the tank fails, the bund secures the fuel and can still be reused without causing any damage.

While most single skin tanks have two years warranty, bunded tanks have ten years. Your fuel is also secured from theft because bunded tanks have a lockable outer lid. The bund also protects the tank from water contamination and condensation. Unquestionably, the safest and most compliant way to store fuel, for both commercial and domestic use, is with bunded diesel tanks.
