·
OSTI ID:5525692
An underground storage tank system for liquids having secondary containment capability and leakage detection capability is described comprising: (a) a rigid inner tank for storing the liquid, having fill pipe and dispensing line; (b) a flexible jacket capable of withstanding sudden stresses without breaking and having sufficient strength to contain any liquid leaked from the rigid inner tank, the flexible jacket encasing the inner tank so as to form a closed space between the tank and the jacket; (c) detecting liquid which at least partially fills the closed space; and (d) non-visual leak detection means associated with the closed space for detecting any change in level of detecting liquid.
