  • Water Tank
    Publication number: 20160002944
    Abstract: A cylindrical upstanding water tank is formed from a plurality of rows of corrugated curved panels bolted edge to edge with a liner extending over the cylindrical wall and support surface to contain the water within the tank. An access opening is formed in one panel of the cylindrical wall and includes a frame with a rectangular planar front flange and a rearwardly extending flange welded into the hole. Liner retention straps surround the hole to fasten an edge of the liner around the hole. An access cover plate is bolted to the front flange of the frame and carries a hoop strength plate which fastens to studs at the rear of the plane so that the plates are removable to allow service access to the interior of the tank.
