Abstract
A storage tank system for storing fluids in an environmentally safe container which includes a rigid external primary tank having a flexible protective secondary inner tank positioned within the tank and drawn, by negative pressure, into contact with the internal walls of the rigid external tank. A continuous monitoring system is connected into, and made a part of, the portion of the system used to evacuate the space between the inner and outer tanks, so that any leakage or loss of integrity which is developed in the liner can be immediately detected at any time.
