Double Wall Tanks

Tank-in-a-tank storage for hazardous liquids

A double wall tank sets an inner tank inside an outer tank, so a leak from the inner wall stays contained. Sizes run from 5 to 6,502 gallons by Peabody Engineering, Custom Roto-Molding, Chem-Tainer and Ronco: Peabody Gemini dual containment tanks (round, square and flat top, including waste oil and antifreeze versions), Peabody ProChem double wall Value-Paks, Chem-Tainer vertical double wall chemical tanks, Custom Roto-Molding white double wall tanks and Ronco economy models.

Use them for acids, bases, used oil and other hazardous chemicals. Check that the tank material suits your chemical and that the outer tank meets your containment plan. See the double wall storage tanks guide.
