Abstract
A storage tank system especially useful for storing liquid gasoline comprises a rigid inner tank having a manhead, a dispensing line extending through the manhead, a sleeve encompassing the manhead, 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 less likely to lose its stored liquid to the environment due to a slow leak or sudden large leak such as is possible with an earthquake and provides total containment capability.
Claims23
A storage tank system having total secondary containment means comprised of:
- (a) a rigid inner storage tank having a manhead for access to the interior of the tank;
- (b) a sleeve attached to the rigid storage tank which encompasses the manhead, said sleeve having a cover which forms a water-tight seal and an opening through which a dispensing line passes;
- (c) a dispensing line extending through the opening in the sleeve in a sealed fashion and then through the storage tank to the interior thereof for dispensing liquid from the storage tank;
- (d) a jacket encasing the storage tank and extending at least to the sleeve so that a closed space exists between the storage tank and jacket whereby any leakage which occurs through the storage tank or manhead will be contained by the jacket and/or sleeve;
- and
- (e) a leak detection means in communication with the closed space between the storage tank and jacket.
The storage tank system of claim 25 further comprising a detection means in communication with the space encompassed by the sleeve.
