Above, Below AST Or UST ?
As the name would imply, underground storage tanks (UST) are buried under the ground, while aboveground tanks (AST) are placed on a pad above ground. Most non-retail businesses prefer AST. Not only is burying a tank beneath the ground more costly than placing it above, it also makes it difficult to install new tanks as your demand for fuel grows. It's much easier to monitor AST (you can simply look at them each day), while UST require remote leak detection systems. If leaks do occur, they're easier to stop when they're above ground; underground, they cause more environmental damage (and thus cause more trouble with regulatory agencies) than when they're above ground. There are advantages to USTs, though. It's more difficult for thieves to siphon fuel from, they give you more space for traffic and you don't have them in sight. In general, though, it's in your interest to install a fuel tank above ground for private fleet fueling purposes.
How Many Walls And Compartments ?
Did you know that a fuel tank can have multiple compartments for different types of fuels to be stored in? Tanks can be made with multiple compartments depending on the length of the tank and its height. If you are using more than one type of fuel, you may want to consider this type of split on your next tank.
Most regulatory agencies require fuel tanks to have "secondary containment" features, which ensure that you will be able to control fuel leaks. A common security feature is a second wall. If a leak should occur in the tank's primary wall, the secondary wall will be able to catch up to 20 percent of the original tank's volume, preventing the leak from getting out of control. Unless you plan to take some other containment precaution, you should invest in a double wall tank most State regulatory agencies require a containment system or barrier to capture any product/fuel leaked from storage tanks.
Vertical Or Horizontal?
Horizontal tanks are generally longer than they are tall, while vertical tanks are generally taller than they are long. Horizontal tanks are generally easier to fit into small spaces, and require less support structure. It's also easier to inspect horizontal tanks for damage, as most of the surface area is open to view. With vertical tanks, the bottom surface area is usually inaccessible, requiring you to lift the tanks up before you can inspect them.Some States may require a pad of some type to be placed under vertical tanks
DEF Storage Tanks
Storing DEF is completely different than gasoline or diesel. DEF is highly corrosive, so it can only be stored in tanks that are resistant to its corrosive nature. This usually means stainless steel or an approved poly tank. If DEF is stored outside, it needs to be protected from freezing. This is accomplished by heating elements around the tank and supply lines.
