Abstract
A containment tank assembly is provided which includes an inner tank, and an outer vessel with a containment area therebetween. Discharge from the inner tank is provided through a discharge outlet preferably located adjacent the bottom wall of the inner tank, the discharge outlet extending through the outer vessel. Anchor assemblies are provided to tie down the roof of the inner tank and to abut the outside of the outer vessel. The outer vessel is preferably configured with substantially flat, vertical chord sections which are tangential to the cylindrical sidewall of the lower section of the inner tank. The inner tank is preferably provided with chutes which fit into notches along the upper margin of the outer vessel to permit liquid to flow from an internal trough back into the lower section of the inner tank and to resist relative rotational movement between the inner tank and the outer vessel.
