What Is a 500 Gallon Double Wall Tank?

A double wall tank (also called a dual-wall or secondary containment tank) features:

• Inner tank – holds the fuel

• Outer tank – acts as built-in spill containment

This design helps meet environmental protection requirements enforced by the Environmental Protection Agency under SPCC regulations.

For commercial operations, double wall tanks are often required to reduce environmental risk and liability.
