Underground Fuel Tank Removal

An underground fuel tank has a life span of 15-20 years on average. But, with proper maintenance, it can serve more than 25 years. However, with time, fuel storage tanks tend to corrode or rust due to chemical reactions and other contaminants. Hence, it is inevitable that you will have to remove your old tank and replace it with a new one.

Make sure to engage a professional underground fuel tank removal company to ensure clean removal and adherence to safety protocols. Network Environmental, with a team of more than 60 engineers and technicians, has been serving the industry for over a decade.

Inspection and Planning: This involves examining the tank’s condition, specifications, and potential risks associated with its removal. After that, a detailed plan is developed, taking into account safety measures, required equipment, necessary permits, and potential contingencies.

Residual Fuel Removal: This is done by draining or pumping out the fuel and taking necessary precautions to prevent spills or leaks. Proper storage containers or tanks are used to contain the residual fuel, following legal and environmental regulations.

Decontamination of Tanks: The decontamination process is crucial to ensure the safe handling and disposal of the fuel tank. Thorough cleaning is performed to remove any hazardous residues or contaminants from the tank. Various methods, such as using water, degreasers, or steam, are employed to effectively clean all surfaces, both inside and outside of the tank.

Purging: Purging involves the removal of flammable gases or vapours from the tank to create a safe working environment. This is crucial to prevent potential accidents or explosions during the removal process.

Dismantling the Tank: If the tank cannot be removed intact due to access issues or safety concerns, dismantling becomes necessary. Using appropriate techniques, such as hot and cold cutting, the tank is dismantled into smaller pieces for easier removal and transportation.

Tank Removal & Disposal: Once the tank is prepared for removal, the actual removal process takes place. Equipment such as cranes or Hiabs may be used to lift and transport the tank from its current location. The removed tank is then transported under proper licensing to a designated waste facility for disposal, adhering to applicable regulations and procedures.

Methods of Decommissioning a Fuel Tank


Abandoning an underground fuel tank involves rendering it permanently out of use and preventing any future use. This method is often employed when removal is not feasible or economically viable. The process typically involves the following steps:

  • Ensuring that the tank is emptied and cleaned of any remaining fuel or hazardous substances.
  • Filling the tank with an inert material, such as sand, foam, or concrete.
  • Sealing the tank openings securely to prevent access and leakage.

Fuel Tank Excavation:

Excavating is a common method used for removing underground fuel tanks. It is used where it is easy and feasible to remove the tank. It involves the following steps:

  • Excavating the area around the tank to expose it.
  • Disconnecting and removing any associated piping and equipment.
  • Lifting the tank out of the excavation using appropriate lifting equipment.
  • Transporting the tank to a designated disposal facility or recycling it as per applicable regulations.
  • Backfilling the excavation site with suitable materials.
