A containment assembly for storing a liquid substance above a ground support surface has an inner tank for receiving and storing the liquid and an outer tank surrounding the inner tank and forming a first air space therebetween for trapping any of the liquid which might escape said inner tank. A support beneath the outer tank provides a second air space between the outer tank and the ground support surface, and a thermal insulating layer substantially envelopes the inner tank, outer tank and support from the ambient. A vapour exhaust vent is provided atop the inner tank, which may include a liquid scrubber for recovering liquids from discharging gases and returning the liquids to the inner tank or elsewhere. Piping is provided for liquid communication between the inner tank and external liquid sources for filling and emptying the inner tank. Instrumentation for measuring the amount of liquid in the inner tank includes a shut-off mechanism for stopping the flow of liquid through the piping to the inner tank when the liquid reaches a pre-set level in the tank. A detector accesses the first air space for detecting liquid leakage from the inner tank. Air exchange is promoted between the first and second air spaces by a plurality of open ended standpipes spaced about the first air space and in aircommunication with the second air space. A heater is preferably provided for forcing heat into the second air space, the heat being distributed through an the standpipes into the first air space and about the inner tank. A second inner tank may be located beneath the outer tank for liquid storage, and may be partitioned for handling selected liquids.
