Tank Selection Guide
Choosing the Right Round Water Tank
The best tank for your property depends on how the water will be used, the space available and how much rainfall you can collect. These four points are a good place to start.
02
How Much Water Do You Need?
Smaller tanks suit gardens, sheds and supplementary storage, while larger tanks provide greater security for homes, farms and properties that rely heavily on rainwater.
03
Check the Available Space
Measure the installation area carefully and allow room for the tank, plumbing and future access. Round tanks offer excellent value where sufficient ground space is available.
04
Consider Your Roof Catchment
Your roof area and local rainfall affect how much water can be collected. A larger tank is most useful when there is enough roof catchment to refill it throughout the year.

More About Round Tanks
Round Water Tank Information
Explore more information about tank suitability, drinking-water quality, sizes, delivery and Tasmanian manufacturing.
Why Choose a Round Water Tank?
Round tanks provide excellent storage capacity and value where sufficient ground space is available. Their circular shape helps distribute water pressure evenly around the tank walls, making them a strong and practical option for household, garden, agricultural and rural water storage.
Smaller tanks are well suited to gardens, sheds and supplementary water storage, while larger capacities can support homes, farms and properties that rely more heavily on collected rainwater.
Safe for Household and Drinking Water
Tankworld round water tanks are manufactured from food-grade polyethylene suitable for storing drinking water when the complete water collection and plumbing system is correctly designed and maintained.
Our polyethylene tanks are manufactured to comply with AS/NZS 4766, while materials intended to come into contact with drinking water are tested to AS/NZS 4020.

Our round water tank range includes capacities from compact 590-litre tanks through to 24,000-litre tanks. This allows customers to choose a tank for smaller garden applications, household rainwater storage or larger rural and agricultural requirements.
Smooth-wall and corrugated designs are available across selected sizes, along with a wide range of colours designed to complement homes, sheds and rural properties. Always check the individual product dimensions before ordering, as diameter and height vary between models.
Preparing for Delivery and Installation
Before delivery, confirm the tank dimensions, prepare a suitable level base and make sure there is clear access to the property and installation area. Allow enough room around the tank for plumbing, fittings, maintenance and future access.
Tank delivery generally involves rolling or lifting the tank from the delivery vehicle. Additional assistance may be required where the tank needs to be moved beyond the standard delivery point or positioned onto a prepared pad.
