ABSTRACT:
Bolted plate water towers have a potential for leakage at abutment joints between the plates, if the gap between the abutting edges is large, and if the water pressure is high enough to extrude the jointing compound out of the gap. But the gap must be wide enough to ensure the edges do not touch. In the invention, a compressible plastic insert (8) is placed between the abutting edges (5,6) to keep the gap from being so variable. Hence, water towers can be built to greater height.
