There are several types of underground fuel tanks that are used to store gasoline, diesel, and other fuels. Some common types of underground fuel tanks include:
- Single-wall tanks: These tanks are made of a single layer of steel and are the most basic and economical type of underground fuel tank. While they are relatively inexpensive to install, they are not as durable as other types of fuel tanks and are more prone to leaks and spills.
- Double-wall tanks: These tanks are made of two layers of steel, with a space in between the layers. The space between the layers provides additional protection against leaks and spills, making double-wall tanks a more reliable and durable option.
- Fiberglass tanks: These tanks are made of a composite material that combines fiberglass with a plastic resin, and are most often double-wall tanks. Fiberglass tanks are known for their durability and corrosion resistance, making them a popular choice for storing fuel underground.
In addition to the materials they are made of, underground fuel tanks can also be classified based on their size and shape. Some common types of underground fuel tanks include cylindrical tanks, rectangular tanks, and square tanks.
