Abstract
A double walled tank is provided for the storage of hazardous materials. The tank comprises an internal tank substantially contained inside an external tank, and substantially reduces the use of internal reinforcements between the two tanks that would disrupt the flow of fluids through the interiors of the tanks. The tank is also provided with a pair of spill boxes that surround access openings to the double walled tank and catch and contain any hazardous material that should leak or spill when loading or unloading the tank.
