Pioneer Water Tanks - Water Tank Sizes and Capacity
A Range of Water Tank Sizes
For more than thirty years now, Pioneer Water Tanks have been helping families in areas across WA in need of large water tanks meet their rainwater harvesting needs, with dimensions and capacities up to 500,000L. Pioneer Water Tanks is an Australian owned company that continues to lead the industry with Aussie innovation and local knowledge.
As well as making round water tanks in a wide range of water tank sizes, Pioneer has ensured that the water tanks we build last well into the future, with a host of testimonials to the quality of our tanks highlighted by the fact that most of the tanks built back in our first year of business back in 1988 still operate to this day.
With a range of capacities available; the dimensions are also important to understand, as two tanks that are the same size in terms of storage capacity may be very different sizes when it comes to diameter, height and footprint.
Pioneer Water Tanks wants to make your water storage purchase as easy as possible, from the quote stage and throughout your tank’s service life, so have put together a guide for all you need to know about water tank dimensions.
Water Tanks Dimensions
What size water tank do I need?
The water tank size that will be best for your home or farm will be determined by both external and internal factors, which include your annual rainfall, the size of your roof or roofs that you are harvesting rainwater from, and the amount of water you use annually.
Your total annual rain harvesting ability can be determined by multiplying your roof size in square meters by your average annual rainfall in mm (microclimate of your property if possible, as it may be different to local rainfall figures), which would look something like the equation below:
Roof Size (m² ) x Annual Rainfall (mm) = Rainwater Harvesting Ability
300m² x 850mm = 255 000L
For the average household sizes, Pioneer Water Tanks typically recommends the following size water tanks:
- 2 Persons: 90 000 litres
- 3 Persons: 110 000 litres
- 4 Persons: 150 000 litres
- 6 Persons: 250 000 litres
However, it is important to remember these figures are simply recommendations, and should not be seen as exact. Some households have higher or lower demands than others, and some have larger dimensions when it comes to roof space, and may choose to harvest additional rain in order to water gardens, lawns or animals.
Pioneer Water Tanks also come with the option of an additional fire reserve of up to 20 000 litres, so if you are looking to use your rainwater tank for fire protection, you may want to keep in mind the extra storage when purchasing your water tank – particularly if you have the extra space and rainwater harvesting ability available.

The Litre/Gallon stated above are gross capacities. Actual useable volume will vary depending on the size and position of inlets and outlets.
Other dimensions of a water tank to consider
When your water tank is installed, there needs to be a clearance of 1m on each side of the tank, in order to prevent any issues when installing, or future access issues for maintenance throughout your water tank’s service life.
This means the width of your tank pad will be 2m wider in total than the diameter of your tank (e.g. a GT110 will require a sand pad that measures 10.02m in diameter).
Any rainwater tanks should also be located 50 mm (5 cm) below the gutter for every 1000 mm (1 meter) away they are located, in order to ensure effective delivery of your harvested rainwater to your rainwater tanks.
For further information on your sand pad location, and heights of any gutters or pipes, your local Pioneer Dealer will be able to answer your question in regards to all applications.
Other water storage tank options
Looking for small water tanks?
While Pioneer Water Tanks are Australia’s #1 big tank company, there are many people who don’t want or simply don’t require such a large water tank.
For these people there are a range of poly water tanks and corrugated water tanks available in a range of styles such as; slimline tanks, round tanks and rain barrels.
These tanks are more for people who have access to mains water, but are looking for a smaller size tank to sue for drinking water or to help them get more value out of their garden.
If you’re not sure if a Pioneer tank or a small water tank will be best for you, get in touch with Pioneer Water Tanks today to discuss the features and benefits of each option.
