Underground tank installations – commercial

Tank Services are specialists to consult when installing underground fuel tank systems.  We are often sub-contracted as part of bigger projects and have helped specifiers and architects with consulting requirements.

Why an underground installation?

Storing fuel underground has major security and space-saving advantages compared to above-ground tanks. Underground oil tanks are out of sight with zero chance of a vehicle collision in a busy traffic environment.  Therefore, they are less likely to cause a pollution incident or oil spill due to physical damage.  The pipework will also be under negative pressure so less likelihood of a major loss of oil due to undetected leaks.

Our process

Our industry experience allows us to provide full project management and risk assessment ‘in-house’.  From start to finish, we cover the ground conditions and preparation, civil excavation, tank, pipework, pumps and monitoring equipment.  Some projects may be subject to planning permission, but we can help with drawing and specification for this as required.  You will need to check with your local planning authority for more information.

What can be stored in an underground tank installation?

Underground Tank Installation ExcavationBelow ground tank installations suit a wide range of fuel storage and flammable liquid applications including:

  • Vehicle refuelling – Diesel and Petrol dispensing with twin compartment tanks available.
  • Generator diesel supply for back up power (Uninterrupted Power Supply).
  • Oil fired boilers and burners – both commercial and domestic heating oil.
  • AdBlue storage and dispensing for diesel vehicles.
  • Specialist chemicals and manufacturing processes.

Tank Services supply and install underground oil storage tanks (USTs) designed and manufactured to BS EN12285 Pt 1. Using steel with a highly corrosion-resistant Endoprene coating and an integrally bunded build, our tank manufacturer ensures the highest construction standards are maintained. 

Leak detection and interstitial monitoring

Our underground double skin tanks use a dry-air leak detection system. With low pressure compressed air monitoring between the tank skins for complete environmental protection against oil leaks.  As part of the underground tank installation process, we can supply and install all the required infrastructure too:

  • Pipework (with an option for leak detection) between the tank and pump, boiler or generator. Belowground ‘pipe-in-pipe’, secondary contained pipe.
  • Above ground stainless steel pipework for internal runs.
  • Install vent pipes and fill cabinets as required.
  • Leak detection systems with alarm outputs for BMS panels.
  • Level gauges and level alarms to monitor your fuel stock locally and via a cloud-based system for remote access to your tank levels.
