Benefits of technology
"The invention relates to a method and system for installing a flexible liner in a tank for water storage. The liner has a base with a substantially rigid extension attached to it, which is then inserted through an aperture in the tank wall. This extension helps to correctly position the liner in the tank. The liner can be installed using a flexible extension attached to the liner base, which is then inserted through the tank aperture. The liner extension can also function as a water inlet / outlet, allowing fluid communication into and out of the liner. The invention provides a simple and effective way to install a flexible liner in a tank for water storage."
Problems solved by technology
However due to the flexibility of the liner, precise installation of the liner within the tank is difficult.
Without proper liner installation, the risk of failure of the water storage greatly increases.
In an incorrect position such as this, excessive stress can be placed on the joints and seams of the liner when the liner is filled with water.
This stress often leads to premature liner failure.

Embodiment Construction
[0056]Referring to FIG. 1, the water storage system of the invention is shown generally as 10. The system 10 includes a flexible liner 12 and a rigid tank 14. The figure shows an exemplary form of the tank and liner that is cylindrical in shape with a circular cross-section. Those skilled in the art will appreciate that this specific form is not essential, and numerous variations can be employed. For instance, a spherical or frustoconical liner / tank as taught in New Zealand Patent No. 244107 may be employed instead.
[0057]Although the tank 14 is rigid, it need not be an integral or one-piece rigid construction. As taught in New Zealand Patent No. 244107, the tank 14 may be made of a number of smaller construction units that are bound and / or attached together to form the rigid tank 14.
[0058]The specific shape of the liner and tank is chosen such that the tank walls are able to support the flexible liner walls when the liner contains a volume of water. As shown in FIG. 1, the size of t...

Abstract
The present invention relates to a method and system for correctly installing a flexible liner in a tank for water storage. The present invention in the preferred form relates to the use of a substantially rigid outlet (20) in the flexible liner (12) that is received in a tank aperture (22) when the liner (12) is correctly installed in the tank (14).
Description
FIELD OF THE INVENTION[0001]The present invention relates to a method and system for correctly installing a flexible liner in a tank for water storage. In particular, although not exclusively, the invention relates to the use of an outlet in the flexible liner that is received in a tank aperture when the liner is correctly installed.BACKGROUND TO THE INVENTION[0002]The use of a flexible liner to store hot water is described in New Zealand Patent No. 244107. The flexible liner is ideally constructed from plastic or polymer material(s) and is located in the interior of a rigid tank structure. The liner functions to store hot water while the rigid tank provides structural integrity to the construction as a whole. This construction reduces heat loss from the stored water and, in combination with the use of cost-efficient plastics and composite material in its construction, is an advantageous alternative to conventional hot water cylinders.[0003]However due to the flexibility of the line...
