Corrosion is the major cause of an underground oil leak. Water is having highly corrosive property, so with prolonged exposure to water your tank will begin to rust and forms cracks and holes.

From Outside of the Tank:

Whether you are having underground or above-the-surface oil tanks, there is a high chance of rainwater and flooding can surround the tank. This overexposure to water can lead to rusting on the exterior walls of your oil tank. To avoid this, the tank should be covered with a plastic coating to seal and prevents it from getting corrosion.

From Inside the Tank:

Water can get into your oil tank from leaks and seepage in the pipes or even from the sedimentation of low-quality oil. This will condense to the walls and causes corrosion from the inside. To identify these, you need to test your tank routinely for any moisture presence. If you found any, you need to call a professional from the oil removal company to deal with this problem.

Improper Installation:

Whether your tank is underground or above, if it was not properly installed, it can easily cause a leak. Underground oil tanks are located around the water table and if there is groundwater present in the soil around your tank, it can cause corrosion. On the other hand, over-the-surface oil tanks can also experience leaks from the improperly installed oil lines and connectors and also due to collapsing legs and support.

Equipment Failure:

The failure of the equipment will also happen over time as the tank ages. Most oil tanks will last around 15 to 20 years and at the end of that period, they will start encountering some problems and failures with their equipment. If your oil tank is new and has a leak, this is because of poor quality equipment and not properly installed. So, make sure to choose a high-quality oil tank than the cheaper one in order to avoid expensive equipment failure.
