At Clean Gas, we provide full propane systems design and installation for commercial and residential projects, including above-ground propane tanks and under-ground propane tank options. But you might be wondering, what is the difference between above and underground tanks. Let’s find out…
Appearance
The main difference between an underground and above-ground propane tank is pretty simple, one is in sight above ground and the other is buried underground. If you care about the aesthetics of your home and you are unable to install an above-ground tank in a discrete location on your property, an underground tank is the solution for you.
Installation Process
If you’re thinking about an above-ground tank, it is important you ensure distance requirements are met and necessary permits are obtained, Clean Gas can help you with this process! If you decide an above-ground is the solution for you, a concrete pad or block will be laid for stability of the tank.
If you are considering an underground tank, there is more involved in the installation process. Same as above-ground tanks, it is important you get a proper permit and advice from Clean Gas. Excavation requires workers to ensure the foundation is firm and the tank is installed at least 18” below ground, secured in its location, cathodically protected, and backfilled safely.
Check out this video to see how an underground tank is installed and this video to see how an above-ground propane tank is installed.
Safety
If your property is prone to flooding, above-ground tanks are the better option for you as underground tanks can float. This could happen when the water level in the hole rises above the level of the gas inside the tank.
However, underground tanks are safer in the event of a leak. Because propane is a green fuel, should there be a leak in your tank, no damage will be caused to the water or soil. If there was a leak in an above-ground tank, there is a chance for the fuel to escape into the air and cause a fire hazard.
Maintenance
Above-ground propane tanks are generally easier to maintain due to their accessibility. Underground tanks are cathodically protected from corrosion that must be inspected and tested on a regular basis, which could result in additional costs to the owner. If the cathodic protection is not functioning it will need to be replaced.
