Why you’re better off with a larger water tank

Farm water storage tank

What size rainwater tank do I need?

A larger tank naturally means capturing more water, but did you know it can also help save you money?

That’s right – the cost per litre decreases as the size of the tank increases. While it may cost more upfront, in the long run, it could be one of the smartest financial decisions you make.

Based on the average cost of water in New South Wales, a GT20 tank with a capacity of 19,100 litres costs 30 cents per litre. Upgrade to a GT250, which holds 247,974 litres, and you’re looking at just 9 cents per litre – a significant saving!

But don’t just take our word for it – listen to Ciara. She installed a tank on her Perth property in 2017, using it for both her household and garden, where she grows a small orchard and vegetable beds.

“The water tank has helped immensely with growing our own food – I don’t think I could afford the water bill if I didn’t have the water supply,” says Ciara.

But a larger tank offers more than just financial benefits. It provides peace of mind.

You can relax knowing that you have a supply of fresh water at your fingertips – a huge relief if you’re either not connected to mains water, or you want to move toward a more sustainable lifestyle.

Megan and Dan recently purchased a GT250 tank for their 5-acre property to ensure they have enough water for both their house and garden.

“We needed a huge tank to accommodate all our water usage, as we don’t have mains supply,” says Megan.

With a larger tank, they are confident that their water needs are met and that they won’t face the hassle of upgrading their storage capacity in the future.

A larger water tank not only guarantees water for domestic use, but also acts as a safeguard against bushfires.

All Pioneer Water Tanks can be fitted with a fire protection valve and a reserve water supply, assisting local authorities in protecting your home if it comes under threat. The more water you have, the better protected your home will be.

Safeguarding against Australia’s unpredictable climate doesn’t stop with fire – drought is another major concern. A larger water tank ensures you have a supply of water for those not-so-rainy days.

For Spence and Kerrie from The Block, that was one of their main reasons for opting for the GT250.

“We decided to go with a much bigger tank than we probably needed, purely to have that back-up in case we’re caught in a drought,” says Spence.

“Now that the tank is installed, we’re happy to see the continuous supply of water.”

Water is Australia’s most precious resource, and a larger tank helps protect this vital resource, making the most of every rainfall.

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.
Shane Jacobson
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!
