Below ground fuel tanks
Below ground double skinned storage tanks supplied by the company are constructed to BS EN 12285-1 from steel approved to BS799. Below ground double skinned petrol tanks are also suitable for storing diesel, gas oil, and other associated oil products.
Below ground fuel storage tanks are available to suit a wide range of applications and can be supplied with storage capacity from as little as 2000 litres up to in excess of 100,000 litres. Site works to accommodate a below ground tank are generally more complicated than those required for above ground tanks and should only be carried out by an experienced and specialised contractor such as TSG, who is able to offer a complete supply and installation service for below ground petrol and diesel tanks.
Double skinned below ground petrol and diesel tanks are constantly monitored for leaks by filling the space between the inner and outer skins (the interstitial space) with an inhibiting fluid, the level of which is continuously monitored by placing a probe in a header tank. Any loss of the inhibiting fluid will be sensed by the electronic probe and cause an audible alarm to sound or send a message to any integrated leak detection system that will complement the overall installation.
As part of the installation service provided by TSG, we can also supply and install all of the necessary pipework from the underground tank. This pipework includes, fill pipes, vent pipes and any associated vapour recovery connections, pump suction, or pressure pipework.
