What is a Double Wall Tank?
A double-wall tank, also called dual shell tank, consists of an inner primary tank and an outer secondary containment tank, creating a tank-in-a-tank system offering 115-120% containment of the inner tank’s capacity. This design provides an additional layer of safety, ensuring that even if the primary tank leaks, the outer containment system will capture any potential spillage.
Designed for both chemical and fuel storage, double containment tanks meet or exceed environmental and safety standards, providing peace of mind for industrial operations.

How Does a Double Wall Tank Work?
Tank Depot’s double-wall tanks are engineered with two integral layers: the inner tank for storing liquids and the outer containment tank for secondary protection. Should the inner tank fail, the outer containment system catches any leaking liquid, preventing contamination of the environment. The tank-in-tank captor tank design also keeps rain, snow, and debris out, ensuring the outer tank remains free from external contaminants.
