ABSTRACT:
A fluid storage vessel and providing spacing protrusions for creating interstitial spaces to permit fluid flow about the outer wall of the inner tank to a collection zone where leaked fluid may be detected. Leak detection devices are provided to determine if the inner tank is leaking fluid. A sump base is formed during the rotomolding process to create a secondary containment layer including a sump base of one-piece construction. The sump base includes entry ports for facilitating the insertion of conduit to access the fluid stored in the fluid storage vessel. The method used to create the secondarily contained fluid storage vessel includes a rotomolding process which provides a seamless construction and eliminates mechanical connections of either the outer shell or the sump base and the shell.
