For a robust, long-term base for your water tank (small or large), we have two recommendations.

1. Concrete Slab. The slab should be 100mm in thickness and exceed the diameter (for Round tanks) or the width and length (for Slim or Thin tanks) by at least 50mm on all sides.

2. Bed of Crusher Dust. Again, 100mm in thickness and exceeding the diameter (for Round tanks) or the width and length (for Slimline tanks) by at least 50mm on all sides.

Both options provide a stable platform for your water tank.

There are two key factors to consider when selecting a tank that best suits your particular requirements.

1. Available Space (usually in proximity to roof downpipes). Given the tremendous rainwater harvesting potential of even the smallest roof area, we would recommend the largest water tank possible given both the ground space and height available. Water storage capacity (capturing free rainwater) is the reason most people purchase a water tank. It’s also important to keep in mind that rainfall isn’t necessarily consistent. It’s best to catch as much of it as possible when it’s available. Please refer to our Products listings for the exact dimensions of our various water tanks.

2. Access to the Proposed Tank Location. Following your answer to the question above, can the tank that you have in mind be moved into the end location? Are their gate widths and other obstacles to consider?

Of course, the expert team at Allstrong Tanks are here to help with any questions you may have regarding your particular requirements. Please don’t hesitate to call them on 1300 949 447 or email them at info@allstrongtanks.com.au.

Yes. All Allstrong Tanks Poly Water Tanks, both round and slimline, are manufactured and quality assured in strict accordance with the Australian Standard (AS4766:2006). For further details on the Australian Standard (AS4766:2006), simply contact the friendly Allstrong Tanks team on 1300 949 447 or email them us at info@allstrongtanks.com.au. Quality is something that we take very seriously. 

‘Poly’ is an abbreviation of polyethylene (PE), which is a robust, chemical resistant thermopoly (plastic). In accordance with the Australian Standard (AS4766:2006), all poly water tanks supplied by Allstrong Tanks are manufactured from virgin, food-grade polyethylene specifically for the containment of potable (drinking) water.

Unlike some plastics (e.g., cheap polycarbonates), which are designed for a disposable, short life span, polyethylene water tanks are completely free of Bisphenol A (BPA).

Due to its safety and remarkable longevity, polyethylene has grown to be the leading material for water tanks in Australia.

The following link leads to some very useful information and an online calculator that takes into consideration roof area and average rainfall to determine how much rainwater can be captured per annum.

As an indication, Adelaide's average annual rainfall is 520mm. 

You’ll be surprised by how much free rainwater you could be catching!

No. For superior strength, aesthetics and overall quality, all poly tanks supplied by Allstrong Tanks are a one piece tank, manufactured utilising the latest rotational moulding technologies.
