Abstract: A water tower can be erected by mounting each of a pair of generally two-dimensional support frames each having an upper portion and a pair of lower ground-engaging feet projecting therefrom for pivoting at the feet about a respective horizontal axis generally at ground level. Then the two frames are pivoted about their respective axes from down positions lying on the ground into up erect positions with the upper portions spaced horizontally apart. An upwardly open vessel intended for the eventual storage of water is then secured between the upper portions to fix the assembly of frames and vessel into a rigid assembly.
