A storage tank system especially useful for storing liquid gasoline comprises a rigid inner tank, access lines extending through the tank, a sleeve attached to the rigid inner tank and encompassing the access lines, and a jacket encasing the tank and at least part of the sleeve. A leak detector is associated with the closed space between the inner tank and jacket to detect leaks. The system results in a storage facility which is not likely to lose its stored liquid to the environment due to slow leak or a sudden large leak by providing total containment capability.

A storage tank system having secondary containment means comprised of: (a) a rigid inner tank for storing liquid; (b) access lines for filling and dispensing liquid to and from the interior of the tank, said access lines extending through a wall of the tank to the interior thereof; (c) a sleeve attached to the inner tank, said sleeve having a cover to form an enclosed sleeve area through which the access lines pass and passage means near its base; and (d) a jacket encasing the inner tank and extending at least to the sleeve so that a closed space exists between the inner tank and jacket and wherein the closed space is in communication with the sleeve area by the passage means so that any leakage which occurs through the inner tank will be contained by the jacket and sleeve.
