Water storage tank

Abstract

A water storage tank is formed by a plurality of curved wall sections adapted to be secured together to form a circular tank. A ground mat is placed on the ground and extends outwardly of the tank wall. A plurality of hold down members are placed at the inside juncture of the tank wall and ground mat. A flooring sheet overlaps the ground mat and extends up and over the side wall of the tank and is clamped to an upper portion of the wall. A tubular fitting extends through a lower portion of the side wall to provide an inlet and outlet for water.

I claim: 
     
         1 . A water storage tank that can be assembled at a remote location comprising:
 a plurality of curved wall sections adapted to be connected together to form a circular wall of the tank;   a ground mat covering the ground within the tank and extending outwardly from the wall a given distance;   a plurality of hold down mechanisms positioned on top of the ground mat having a first horizontal portion and a second vertical portion extending upwardly along the wall of the tank;   a flexible tank floor formed of sheet material overlying the ground mat and extending upwardly and over an upper portion of the circular wall of the tank; and   a plurality of clamps for clamping the flexible tank floor to the upper portion of the circular wall of the tank.   
     
     
         2 . A water storage tank according to  claim 1  further including a tubular fitting extending through a lower portion of a wall section for providing fluid communication between the tank and a fluid conduit. 
     
     
         3 . A water storage tank according to  claim 1  wherein the hold down mechanisms further include a curved section between the horizontal and vertical portions. 
     
     
         4 . A water storage tank according to  claim 3  wherein the hold down mechanisms are curved in a horizontal plane to conform to the curvature of the tank side wall. 
     
     
         5 . A water storage tank according to  claim 1  further including a protective mat positioned between the ground mat and the flexible floor. 
     
     
         6 . A water storage tank as claimed in  claim 1  further comprises a strip of protective material overlying the hold down mechanisms to protect the flooring from corners of the hold down mechanisms. 
     
     
         7 . A water storage tank as claimed in  claim 3  wherein the hold down mechanisms include a reinforcement L-shaped member extending along the curved portion of the hold down mechanism.
