ABSTRACT:
An underground storage tank assembly and method for fabricating the same are disclosed. A steel primary fluid storage tank is provided having an outer, peripheral surface. A secondary fluid storage container being formed of curable plastic material and having a substantially smooth inner surface is tightly secured about the outer, peripheral surface of the primary fluid storage tank. The interstitial spaces formed between the outer surface of the primary container and the inner surface of the secondary container permit the desired migration of fluid therethrough to allow the detection of any fluid leaking through the primary tank or secondary tank. Various methods for forming the secondary fluid storage container are disclosed. The outer surface of the primary tank and/or the inner surface of the secondary fluid storage container may be textured for applications requiring enhanced fluid migration.
