GT220: 220,000L Water Tank

Is a 220,000L rainwater tank suitable for you?

Pioneer commonly recommends 220,000L water tanks for a domestic household of four or five people – in areas outside of Australia’s capital cities – looking to make their water storage go a little bit further, in order to meet their needs for drinking water and household water storage, and perhaps also support a small garden.  The GT220 is Pioneer Water Tank’s 220 000L water tank, with a gross capacity of 221,097L of rainwater storage.

For this reason, the GT220 is one of Pioneer Water Tanks most popular products and is the first choice for many of Australians all across the country in each year, looking to ensure they have a reliable and long lasting water storage solution. Rainwater tanks upward of 200,000L are also popular amongst farmers and folk on cattle stations.

Many customers purchasing a rainwater tank are rural families with no access to mains water or town water – or are simply looking to no longer rely on it – which means it is important to have enough rainwater harvesting ability and a large enough water tank to meet your needs.

Gross capacities

If you’re looking to determine if a 220,000L water tank is suitable to service your home, you can consult our water storage calculator (below) to determine how much rainfall you can capture from your roof, and make sure to track of how much water your household is using.

The below table shows the dimensions and gross capacities of the GT220 – Pioneer’s 220,000L water tank, as well as the GT200 and GT250 model water tanks, the sizes either side.

Calculate your perfect water tank size

We estimate that the average rural home requires approximately 30,000 litres of water storage per person.

To work out how much rainwater you can harvest from the roof of your home (catchment area) use the simple calculator attached.

The Pioneer Water Tanks Difference

Pioneer Water Tanks have been Australia’s leading manufacturer of 220,000L rainwater tanks for Australian farmers and families for over 30 years and continue to lead the industry for innovation and quality.

All Pioneer Water Tanks – whether you’re installing a 20,000L tank or 220,000L tank – are manufactured in Australia, from Australian Zincalume® or Colorbond® Steel, and Pioneer remains an Australian family owned business to this day.

The Pioneer V-Lock® tank wall profile is specially designed with water storage in mind, not only providing superior strength and durability, but also protecting your liner from the stretching and stress that can come with the filling and emptying of a regular corrugated wall panel.

Our Aqualiner Fresh® Antimicrobial water tank liner works from inside your tank to help keep your water cleaner and fresher for longer, protecting your family from nasty bacteria, and potentially saving costly cleaning fees down the line.

Pioneer’s 220,000L water tanks – along with the wide range of Pioneer Water Tanks – come with our 20/20 Warranty, which is a 20-year conditional structural warranty as well as a 20-year conditional warranty against water leakage.

Tank factors to consider

Fire Reserve

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.

Irrigation

When looking to irrigate, factors such as water source, harvesting capacity, and usage volume will all need to be considered.

Water Source

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.

Rainwater Harvesting

The size of your roof catchment area, in addition to your annual rainfall will determine how much water you can harvest.

Domestic Usage

Having an idea of what domestic functions you intend to connect to your tank and how often each will be used will be advantageous.

Total Volume

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.

What comes with my 220,000L water tank?

Every 220kL Pioneer Water Tank features a suite of standard water tank accessories, as well as a range of optional accessories that you may wish to choose to include in the purchase of your rainwater tank. 

Included in these standard water tank accessories is the Pioneer Water Tanks exclusive Aqualiner Fresh® antimicrobial water tank liner, designed to keep your harvested water fresher for longer.

220,000L Water Tank FAQs

How much water storage do I need?

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 vs steel water tank prices

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.

How much space will I need for my water tank?

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.

How long will it take for my water tank to be installed?

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.

What is the difference between "gross" and "effective" capacity

“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.

What is the standard size of a water tank?

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.

What accessories come with my water tank?

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.

Do you want bacteria in your water? I don’t! It’s drinking water. Do you want your kids eating or drinking mould? I don’t. But that’s what I’ve got in those tanks, a bacteria fighting lining, it’s genius.

We like to do things very naturally, which is why we appreciate the beauty of fresh rainwater. I don’t like plastic, and I only ever want to supply our customers with clean, quality water.
David Ritchie
That steel is a big part of the reason why we went with Pioneer Water Tanks. The Colorbond® colours also matched up perfectly with the house – which we had recently painted Woodland Grey. We chose this colour as we wanted the house to blend seamlessly into the beautiful natural rural environment.
Jamie Adamson
We knew we needed a huge tank to accommodate all our water usage due to no mains supply. This will initially be for the whole house, and for the garden if we have any left over. Dan had a good idea of how big this tank would be, but I couldn’t believe it when it was installed! It’s massive!
