There are many factors that affect the cost of removing water or fuel storage tanks. The most important factors include whether the storage tank is above or below ground, the tank's size, whether there is evidence of leaking and what was stored in the tank. Underground storage tanks cost an average of $2,500 to remove due to the added labor of excavation and the need to locate any underground pipes or utility lines. The larger the tank, the more it costs to remove. The orientation of the tank is another factor in its cost; a horizontally constructed tank that is underground costs less to remove than a vertically constructed storage tank. This is because of the added time to dig out a deeper tank.

A leaking tank may require environmental remediation of the surrounding soil and any nearby water sources if the tank held fuel. If the tank was damaged due to age, soil conditions or severe weather, it may cost more to remove. Remediation may cost $10,000 or more depending on the scope of the pollution. Extensively contaminated properties due to large leaks from fuel storage tanks may cost up to $100,000 to remove the tank and restore the property to a safe condition. Tanks that stored fuel or oil cost more to remove due to potentially hazardous conditions associated with leftover fuel and any vapors. Old fuel needs to be properly disposed of, which may add additional fees.

Why a Fuel or Water Storage Tank May Need to Be Removed

Safety, government regulations and dysfunction of the tank are some common reasons why property owners may need to have it removed. If the tank is located underground, it can leak, proving a risk to the environment and the property owner, and get worse over time. Property owners may no longer need the tank due to changes in how the property is used (for example, if they install a new heating unit that doesn?t require oil) or the municipality may have added a supply of water, natural gas or other fuel that the property owner may use. In some cases, the property owner needs a replacement tank brought in for increased capacity or to comply with local, state or federal regulations. If tests have shown that the tank is damaged from rust or improper installation, the law may stipulate removal of the old storage tank. The presence of an old fuel or water storage tank may also interfere with the sale of the property. In some cases, a municipality may not allow the property to be sold until the old tank is removed.

Reasons to Hire a Professional for Removal of a Water or Fuel Storage Tank

Removal of a water or fuel storage tank is a complex undertaking. A permit may be required by local, state or federal authorities depending upon what the tank stored. A professional is also able to take steps to ensure that the tank doesn't leak out volatile fluids during the removal process. Experienced professionals also take steps to ensure that removal complies with all regulations regarding potential soil and water contamination as well as the disposal of leftover fuel and contaminated tank parts.
