A bunded fuel or oil tank is simply a double tank. It has two layers: the inner and the outer layer. The inner tank is where fuel is stored and the outer tank serves as a backup in case of a leakage or spillage. Any excess fuel will be contained in the out layer or the bund. Bunded tanks are a requirement for any commercial and industrial operation. These fuel tanks are made of either plastic or steel. Plastic or poly diesel fuel tanks are lightweight, customizable, and less costly. Steel fuel or diesel tanks are heavy and extremely robust.
As a Requirement
All commercial and industrial operations that store fuel for more than 200 liters must use bunded fuel tanks. For domestic use, one can have the single skin tanks, but must carry out a risk assessment for fuel storage. In some cases, you may be required to use a bunded tank for domestic use if you are storing more than 2,500 liters of fuel, near an open drain or loose manhole, and when the tank is located within ten meters of river, stream, boreholes, spring or well. You would also need to use a bunded tank if your tank vent is not visible from the filling point, and if the fuel use if for the entire building and not for a single-family dwelling.
Choosing your Tank
Choose the fuel tank that best suit your need and application. Each type has its own pros and cons, but the best one is the one that fits your operations. Plastic fuel tanks are designed specifically to protect your fuel from extreme heat of the sun because the material used has a natural heat-proofing ability. Thus, it is ideal for fuel tanks that are installed aboveground. Steel fuel tanks are very sturdy and can protect your fuel from theft. It can last long for up to twenty-five years.
These tanks are built to last with superior durability. However, you must also do your part to install and maintain them properly. Installation of the fuel tank must be done by a professional to make sure that everything is properly set up. Installation must also adhere to the standard regulations and policies.
Regular inspection and maintenance is required to make sure that early signs of damage can be detected right away, preventing corrosion and contamination. During extreme weather conditions such as storms and heavy rains, you need to inspect your fuel tank and make sure that there is no damage or rainwater flooding in your tank.
While it is crucial to maintain the quality and condition of your fuel tank, it is equally important to keep the quality of the fuel you are storing good as well. Any signs of damage and deterioration must be addressed right away. Let a professional engineer take care of any necessary repair.
