Can wildlife cause damage to a buried propane tank?

Digging and Burrowing Risks

Wildlife such as moles, gophers, and rodents are notorious for their digging activities. If a propane tank is not encased in a concrete vault or protected by a durable metal sleeve, these animals may burrow into the surrounding soil, potentially puncturing the tank. The average mole can excavate 18 to 20 feet of tunnel in a single day, posing a significant threat to a buried propane tank.

Soil Erosion and Compaction

Another risk associated with wildlife damage is soil erosion and compaction. The constant movement of animals in and around the tank can cause the soil to settle unevenly, leading to potential damage to the tank or its connections. For example, if the soil becomes compacted, it may prevent the tank from being properly secured, making it more susceptible to damage from external forces.

Installation and Security Best Practices

To mitigate wildlife damage, propane tank installers should adhere to established best practices. This includes burying the tank at a minimum depth of 12 inches below grade, using a concrete vault or metal sleeve to protect it, and installing a secure lid or cap to prevent animals from accessing the tank. Additionally, installers should ensure that the soil surrounding the tank is compacted and stable to prevent erosion and settling issues.
