Q. Why does the tank base have to measure 300mm around the perimeter of the oil tank?

A. The fire protection provided by the base is to help prevent the tank itself from becoming overgrown and in turn to help protect against fire spreading across the ground to the contained fuel from another source. If the tank is raised on piers, the platform supporting the tank should be sized to sufficiently support the tank. Reference should be made to the tank manufacturer’s installation instructions.

Q. What is the life expectancy of an oil storage tank?

A. Most plastic bunded oil tanks come with a 10 year manufacturers’ warranty and when properly installed and maintained can last for many years beyond its expiration date. Fuel pumping and tank equipment usually comes with the standard manufacturers 1 year warranty. The tanks that are available at RPM Fuels and Tanks are constructed using the best base materials and the most reliable fittings to ensure you’re provided with the best possible oil storage solution.

Q. What is a bunded tank?

A. A bunded oil tank is simply a tank within a tank, with fuel being stored within the inner tank. The reason behind the design is to ensure that there is no fuel loss due to the occurrence of a spill or like for like incident. The outer tank not only provides you with a failsafe it can also avert any pollution incidents.

Bunded oil tanks are a requirement at commercial, industrial, institutional and commercial premises and at most domestic installations in the United Kingdom and Republic of Ireland.
