At NSW Water Tanks, we proudly supply Pioneer Water Tanks as an authorised dealer, helping families and rural landowners throughout Wollongong and nearby regions find the ideal rainwater storage solution.
For households of three or more seeking long-term water security, the GT130 model – a 130,000L steel water tank – is a popular choice. This size offers peace of mind during dry periods and provides more than enough capacity to cover daily needs like drinking water, laundry, showers, and even garden irrigation.
In the greater Illawarra region and across rural New South Wales, many property owners—especially those on farms or small acreages—prefer large rainwater tanks in the 130,000-litre range. These tanks are also well-suited to agricultural use, including water storage for cattle, crops, and other farming operations.
If your property depends on harvested rainwater for its full water supply, it’s crucial to install a tank that’s large enough to meet your household’s needs while also ensuring your rainwater catchment area can effectively fill it. Our team at NSW Water Tanks can help you assess your roof size, rainfall averages, and water usage to make the best decision for your circumstances.

This is a volume of water that is always readily available in the event of fighting fire. Commonly this can be up to 20,000 litres.
When looking to irrigate, factors such as water source, harvesting capacity, and usage volume will all need to be considered.
Harvesting water from a roof, filling up from a bore or dam will impact the size of water storage tank that will be most optimal for you.
The size of your roof catchment area, in addition to your annual rainfall will determine how much water you can harvest.
Having an idea of what domestic functions you intend to connect to your tank and how often each will be used will be advantageous.
It’s better to have water and not need it, than to need water and not have it. It may pay to install a bigger tank to mitigate running out of water.

Among the standard inclusions is the exclusive Aqualiner Fresh® antimicrobial tank liner, designed by Pioneer to help keep your harvested rainwater cleaner and fresher for longer.

The closest Pioneer model to a 130,000-litre tank is the GT130, which has a gross capacity of 129,292 litres. If you’re after something slightly smaller or larger, we also supply the GT110 (110,166L) and the GT150 (149,948L) from the Pioneer Water Tanks range.
The average Australian uses somewhere around 120,000L of water a year, but does that mean you need 120,000L sized water tank for each person in your home? Thankfully the answer to that question is no, as this number is based mostly on suburban figures, where the vast majority of water is used on irrigation and toilet flushing, and the typical rural home uses much less water than this.
We estimate that the average rural home needs about 30,000L of water per person, per year, and if you’re relying on that alone, a rainwater tank that exceeds this figure would be sufficient. Of course, your ability to harvest rainwater is also heavily dependent on your annual rainfall.
Poly Water Tanks typically only come in sizes of up to 50,000L, which typically isn’t enough water supply for any more than two people with no access to mains water supply.
Pioneer’s Steel Water Tank Sizes range from our smaller GT10 which comes in at 12,200L all the way through to our GT500 which has a water storage capacity of 500,000L. Larger or more specific water storage facilities for commercial or industrial applications can also be quoted to order.
Whilst the answer to this is entirely dependent on what size water tank you order, a safe rule of thumb would be to ensure a space 3m wider than the diameter of your desired water tank. This ensures comfortable room for the required 1m on all sides for the pad, and ensures there will be no difficulties at the time of installation.
With over 50 Dealers Australia Wide, we try and make the delivery of our water tanks as efficient and effective as possible. Typically a Pioneer Water Tank is delivered within 3 to 5 weeks of an order being placed. However, if special circumstances require a shorter delivery time, give us a call and we can endeavor to have your water tank installed as soon as possible.
“Water tanks are listed as ‘Gross’ capacity as an industry standard and represents the total volume of water that the tank can hold. Indeed all tank manufacturers use this standard to represent each of their size options. The ‘useable’ capacity or ‘net’ capacity will vary according to what each individual requirement are. For example, fire reserves, sludge zones, scour drains, gravity issues etc will affect where outlets are placed.
Pioneer offers an oversized, ‘bell mouth’ internal fixture which allows for water volumes to reach very close to the top of the walls.
If you are assuming the overflow that penetrates the wall is at the top fill level, that is not the case – the diagram on this page shows how this works. The top of the water level is only about 120mm below the top of the wall which allows for the roof trusses to just sit clear of the water.
As everyone’s water harvesting and rainwater storage needs are different, depending on their annual rainfall, water usage, and roof size, as are standard water tank sizes. Pioneer Water Tanks offer sizes from 12,000 litres to 500,000 litres with 110,000 litres being the most common for rural homes. If you are unsure call us on 1800 999 599, and our sales team will be able to assist.
All Pioneer Water Tanks come with our standard accessories, including but not limited to; our industry leading AQUALINER FRESH® tank liner, our 150mm diameter tank overflow and a galvanised ladder. In addition, a range of optional tank accessories are also available for your water tank.
