What is the typical burial depth for steel tanks?

The typical burial depth for steel tanks is generally around 5 feet. This depth is considered effective for both structural integrity and meeting regulatory requirements for underground storage tanks. At approximately 5 feet, tanks are usually below the frost line in many regions, which helps prevent damage from freeze-thaw cycles. Additionally, this depth helps in maintaining a sufficient amount of soil cover, which minimizes the risk of corrosion and allows for proper soil grading and drainage to protect the tank from environmental factors.

The standard practices regarding tank installation have evolved due to both engineering assessments and compliance with safety regulations. Therefore, placing steel tanks at this depth also aids in ensuring that they are less susceptible to external pressures while still accessible for monitoring and maintenance when necessary. Understanding these standards is crucial for anyone involved in the installation and retrofitting of underground storage tanks.
