A relocatable storage tank for flowable materials such as liquids and granular materials comprises a bag of flexible material and has a generally square, rectangular, or circular shape, resting on a solid surface, together with at least one central post which supports the upper portion of the bag, wherein the post aids in carrying the weight of the flowable materials to the ground, thereby reducing the associated mechanical tensions in the fabric of the flexible material.
