What type of tank is commonly used for underground fuel oil storage?

Underground storage tanks (USTs) are specifically designed for the purpose of storing fuel oil and other hazardous substances underground. These tanks are typically made from materials that can withstand corrosion and are designed to prevent leaks into the surrounding soil and groundwater.

USTs are commonly used due to their ability to minimize environmental impacts and save aboveground space, making them a preferred option for many commercial and industrial applications. The design of USTs includes safety features such as double-walled construction and leak detection systems, which help ensure that fuel is securely stored and monitored.

In contrast, aboveground storage tanks (ASTs) are situated on the surface and usually require different regulatory considerations and risk management procedures compared to USTs. Portable fuel tanks are designed for temporary usage and are not used for long-term storage. Drainage tanks serve entirely different functions related to stormwater management and do not pertain to fuel storage.
