Abstract: A system and method for cleaning an above ground storage tank, where the side walls of the tank are separable from a bottom of the tank. Verticals members may be attached to the side walls of the tank, and a lifting force may be applied to the vertical members by a series of jacks so that the side walls are raised above the bottom. The side wall may be suspended above the bottom while the tank is cleaned out, and then lowered again when the cleaning is complete.
