What is the maximum burial depth allowed for fiberglass tanks in both traffic and non-traffic conditions?

The maximum burial depth allowed for fiberglass tanks under both traffic and non-traffic conditions is indeed seven feet. This regulation is important because it ensures that the tanks are adequately protected from external pressures while minimizing the risk of structural failure or leakage. Fiberglass tanks are designed to be durable, and their material properties allow them to withstand significant external loads, but there are limits to prevent damage during installation and throughout their lifespan.

By adhering to the seven-foot burial depth, operators help ensure compliance with safety and environmental regulations. This depth is recognized as optimal for maintaining structural integrity, while also allowing for practical installation and access considerations. Understanding these guidelines is crucial for those involved in the installation and maintenance of underground storage tanks, as improper burial depths can lead to catastrophic failures and environmental hazards.
