UNDERGROUND TANKS
For domestic applications
Underground fuel oil storage tanks are a popular option for
small gardens, sensitive landscapes and additional
protection when compared to above ground fuel oil storage
options.
Balmoral underground fuel tanks are rotationally moulded in
polyethylene to produce one piece seamless bodies and necks.
They provide discreet and safe storage of oil and diesel. The
tanks are designed using computer engineering analysis
techniques to ensure optimum strength and performance for
underground installation to a standard depth of 500mm.
A basin at the top of the tank neck (See Figure 6) contains a
2” fill point, offtake, contents gauge and overfill prevention
valve, all of which are easily accessed via the lockable
mushroom lid.
A Tigerloop is also supplied with all underground fuel tanks.
The tanks are available in working capacities ranging from
1370-3090 litres to account for both dead volume and a safety
margin.
If you require a tank that doesn’t occupy space in your
garden, or you have restricted space, then a Balmoral
underground tank is the natural choice.
Balmoral underground tanks comply with the requirements of
British Standard BS5410 part 1, Section 6.4h.
