What is the typical lifespan of underground storage tanks (USTs)?

The typical lifespan of underground storage tanks (USTs) is generally accepted to be around 20 to 30 years. This timeframe is based on various factors including the materials used in construction, environmental conditions, and the maintenance practices implemented.

USTs are often made from materials like fiberglass or steel, which can significantly impact their durability and resistance to corrosion and leaks. Additionally, tanks that are regularly inspected and properly maintained are likely to reach their expected lifespan or even exceed it.

Understanding this typical lifespan is crucial for operators in the gas station and fleet service industries, as it helps in planning for replacements and ensuring compliance with safety regulations. Proper management of USTs not only extends their service life but also minimizes environmental impact and the risk of costly leaks.
