The present invention relates to a storage tank, and in particular, to a liquid or rain water modular storage tank.
Water tanks are used to collect and store run off rain water from the roof of a building or structure. Whilst water tanks have been used in rural and industrial areas for some time, they are becoming increasingly more popular in urban areas. With a growing population combined with a heightened environmental awareness more and more people are using rainwater tanks to service their homes and businesses.
A typical water storage tank needs to be large enough to support the requirements of a user and strong enough to withstand the hydrostatic pressure exerted by a full tank. As such the tanks are generally bulky and take up excessive space. Whilst underground tanks are available, it is more desirable to position a tank above ground for on-going access. Besides avoiding excavation costs, cracks and leaks can be detected sooner and the tank is more accessible for cleaning and maintenance.
However, a disadvantage of above ground water tanks is the space required for installation. A typical water tank requires a large space, and in urban areas, yard space can be limited. Additionally, traditional water tanks are one-piece and round or oval shaped for optimum strength. Consequently, transporting a water tank can be costly and generally inconvenient. If a tank is to be located in a confined space, it may also be necessary to lift the tank over fences, houses or through neighbouring properties. In some cases confined space access may prevent the installation of a traditional tank.
Another disadvantage associated with known water storage tanks is that they typically require conventional fasteners such as nuts and bolts to secure the various components during assembly. Accordingly, there may be significant time and costs associated with assembling such water storage tanks, particularly if the correct tools are not readily available, or if the fasteners in the tank kit are misplaced.
There is a need for a modular water tank that can be transported in pieces through limited access areas and assembled together at the desired location. However, a modular tank must confidently withstand the hydrostatic pressure created when the tank is full. Additionally, the amount of fasteners required should be limited in order to minimize the cost and complexity of assembly. In a preferred form, there should be no nuts and bolts or other traditional fastener types. There is also a need for a modular water tank having components that have relatively smaller profiles and/or less overall components so as to minimize the amount of materials required to fabricate these components, thus reducing the overall manufacturing costs and simplifying the assembly process. Such a structure may also at least allow for persons of smaller build the ability to assemble and install the tanks on their own.
It is therefore desirable to provide a modular tank that is cost effective, easy to assemble and can withstand the hydrostatic pressure when the tank is full of water.
It is the object of the present invention to substantially overcome or at least ameliorate one or more of the above disadvantages, or to provide a useful alternative to existing arrangements.

Preferably, the means to attach the flexible material to the frame includes a clip having an open mouth adapted to receive the flexible material.
Preferably, no nuts or bolts are utilized to fasten the tank together.
Preferably, locking plates or tongue and groove or raised pins and slots or similar are used to fasten the tank together.
Preferably, the tank further includes a second liner to be located between the flexible material and the frame to protect the flexible material from sharp edges.
Preferably, the second liner includes geotextile material.
Preferably, the supports include a flange adapted to protect the flexible material from sharp edges.
Preferably, two or more of the modules are assembled in a rectangular configuration.
Preferably, two or more of the modules are assembled in an ‘L’ shape configuration.

Each tank 10 includes an inlet 32 through which water can flow into the chamber 14, and one or more outlets (not shown) from which water can exit the chamber 14. Preferably, one of the outlets is an overflow outlet.
The top portion 18 includes a cover panel 30 secured to the edge members 22 and cross members 24 using fasteners 40 or the like. The cover panel 30 may include the inlet 32. The cover panels 30 are interchangeable to allow selective positioning of the inlet 32. The inlet 32 can also be located on one or more of the side panels 28. There could also be more than one inlet 32.
The outlets may be located on one or more of the side panels 28. The side panels 28 are interchangeable to allow selective positioning of the outlets. It will be apparent to a person skilled in the art that, in use, the inlet 32 must be positioned above the outlet(s).

a, 12b and 13 show a first embodiment of a modular storage tank 100 which is of the same general form as the modular tank 10 described above. However, it will be appreciated that the modular tank 100 does not require traditional fastener such as nuts and bolts to assemble the various components.
As best shown in
The members 104 of the tank 100 are designed to be joined, or “clipped” together by inserting the rivets 102 into the corresponding keyhole cut-outs 103, and then sliding the rivets 102 into the narrow section of the keyhole cut-outs 103. Once the two parts are connected in this manner, they are prevented from being separated easily as the head of the rivet 102 is wider than the narrow section of the keyhole cut-out 103. It is envisaged that one or more additional locking plates 105 with rivets 102 may be used to connect some components to provide added security for the connections and prevent accidental disconnection. It will be understood that the assembly of the components of the tank 100 and the use of panels 28 sliding in the channels is generally similar to the assembly of the tank 10 as described above. In a preferred form, the locking plates 105 are disposed in the interior space of the frame, such that the locking plates 105 are not visible (or at least to a minimal extent) from the exterior of the frame. It will also be appreciated that the width and length dimensions of the various components of the tank 100 may be modified to be any suitable size for the intended application. In the embodiment as shown in
As best understood with reference to the exploded view of the tank 100 of
In this embodiment, the frame of the tank 200 is substantially smaller than the frame of the tanks 10 and 100 described above. The number of components required to assemble the tank is reduced. The various components of the tank 200 have a smaller profile and thus less material (i.e. steel) is required to create the components, which may at least lower the overall manufacturing costs and provide a more visually appealing form of storage tank for the consumer. In this embodiment, the tank 200 may also include additional support members 120 arranged to extend between opposing members 104. Each support member 120 may be arranged to extend between opposing members 104 at any suitable location, e.g., at the center of the frame as shown in
Although the invention has been described with reference to specific examples, it will be appreciated by those skilled in the art that the invention may be embodied in many other forms.
