A storage tank having primary and secondary containment means is made from a rigid outer tank shell by forming an inner tank shell of fibrous reinforcing material and resinous material. A gas pervious material is initially positioned on the inside surface of the rigid tank. Leak detection means is used to monitor the closed space between the rigid outer tank and formed inner tank.
A method of forming a storage tank system having primary and secondary containment means and the capability to monitor each containment means for leakage, comprising the steps of: (a) applying a gas pervious separating material having a thickness ranging from about 0.025 inches to about 2.0 inches to substantially cover an interior surface of a rigid tank shell, said separating material characterized in allowing liquid to readily pass therethrough; and (b) applying fibrous reinforcing material and a resinous material onto said gas pervious material so th...
