500 gallon propane tanks can be buried underground or live above the ground. Some would rather not have to look at it. Others would rather not have their yard excavated. In fact, to bury the tank requires a 12 foot long and 5 foot deep trench. However, once it’s down there, you can plant grass or bushes above it. The added curb appeal might actually improve the value of your home

The installation costs for an underground propane tank installation costs are considerably higher than above ground models. It requires trained professionals to dig up your yard, plant the tank on a firm foundation, and backhoe a smooth fill on top of the gas tank.

But the refill and maintenance costs are the same for both once installed.
