Pioneer Water Tanks - Leading the way in water

Western Australian Water Tank Manufacturer

Pioneer Water Tanks are a proudly Western Australian rainwater tank manufacturer and supplier, who have been helping families, farms and businesses all across Australia meet their water storage needs for more than 30 years.

Australia is the driest inhabited continent on the planet, and because of this, has the most water storage per capita looking at both dams and water tanks combined.

Rainwater tanks have long been essential to the way of life for rural Australians, and provide numerous homes who would otherwise have no access to drinking water with a water storage solution that doesn’t compromise on water quality.

In the hundred or so years Australians have been relying on water storage, the technology that goes into a rainwater tank has come a long way, allowing for larger water tanks that last longer, and allow for higher quality water supply to the homes they are attached to.


Pioneer Water Tanks have provided a service for Western Australia since 1988. Our high quality Australian-made water tanks will provide the long-term water security you’re looking for.

Rainwater Tanks for Western Australia

More than a third of households in Western Australia outside of the Perth Metropolitan Area are equipped with water tanks, due to having either no access to mains water or town water supply, or limited access.

Even when it comes to water tanks for Perth, and surrounding areas considered as the capital city population, more than 5% of homes have some form of rainwater tanks – either to save on the water bill, to help use in the washing machine or garden, or even for drinking water purposes.

Pioneer Water Tanks is Western Australia’s number one big tank supplier, with water tanks from 12,000L to 500,000L for large scale rain harvesting for semi-rural or rural homes, as well as farms and stations across the state. Pioneer Water Tanks also provides fire protection water storage for commercial or industrial sites, as well as mining operations.

Benefits of Rainwater Tanks

Access to clean, fresh water

For many people in Western Australia, and all across the country, a rainwater tank means reliable access to clean, fresh water for their home. With no access to mains water from a local council, these homes rely on rainwater for their showers, kitchens and bathrooms, as well as to water any gardens or plants they may have in the home.

Pioneer Water Tanks are equipped with the Pioneer exclusive Aqualiner Fresh® antimicrobial water tank liner, which actively protects against contamination from algae and bacteria without the need to add chlorine or any other chemicals to the tank.

It is important to keep any gutters, roof area and plumbing that leads to the water tank clean and free of debris – and consider installing a first flush diverter – in order to ensure that the water going into your rainwater tank is as clean and healthy as it can possibly be.

Typically water tanks fitted with the Aqualiner Fresh® antimicrobial water tank liner do not need cleaning, however if you do need to have your tank water inspected, contact your local Pioneer Dealer Direct® Network member, and they will be able to assist you.

Bushfire protection

In the hot summer months, which only seem to get longer with each passing year, bushfire is always a threat in Western Australia, and in rural areas one of your best forms of defence against bushfire is a water tank fitted with a fire reserve and the correct fire valves – in fact, some shires now have a fire reserve as a requirement for new home builds. If you are unsure of the connections, contact your local council, and they will be able to point you in the right direction.

In 2006 the CSIRO carried out bushfire testing in collaboration with the Bushfire CRC, and tested a number of tanks to see how they held up when exposed to a fire front. When compared to the other tanks, which included a prefabricated steel tank and a poly water tank, the Pioneer Water Tank came out comfortably on top.

Pioneer’s steel liner tanks were the only tanks tested that maintained integrity during all tests. The liner construction proved able to retain water during and after the 30 minute fire front, which is critical for the protection of property and assets in the event of a bushfire.

Freedom from water restrictions

Western Australia is home to some of the strictest water restrictions in the country, and due to this many households look for other ways to water lawns and gardens. For many people who work jobs and have busy lives, hand watering simply isn’t practical, and if stricter restrictions kick in, may also not be allowed.

Due to this, many people turn to water tanks – be they slimline tanks or a more standard round tank – in order to store their own water in preparation for the long dry spells that a WA summer provides. For these people, a smaller tank size is usually required in comparison to those looking to supply potable water to their entire home, meaning that a small plastic tank will usually suffice.

Frequently Asked Questions

What size rainwater tank do I need?

The size of rainwater tank that would be best for your home is dependent on a number of factors – even if you are using it as your primary water source with no access to mains water. These factors are things like your annual rainfall (mm),  roof size (m²) and the number of residents in the home are the major determinate factors.  

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.

For related information on water tank sizes, check out our page on the topic.

Do rainwater tanks need a pump?

Typically rainwater tanks to not require a pump, as the water contained in the tank is heavy enough to create adequate water pressure to push the stored water to any taps or pipes within the home. When tanks are located too far from the house, or are perhaps close to empty and don’t have sufficient weight to create adequate water pressure, a pump may be required.

Do rainwater tanks save money?

For most Australians looking for a large steel water tank, money saving isn’t the priority, as much as ensuring reliable water supply to their home or building where there is no mains water. That said, rainwater tanks certainly can save money on your water bills, particularly in the long term. While a rainwater tank is already a solid investment, freeing you from the grid, the more water prices increase by, the more money your rainwater tank will have saved you.

How long will a rainwater tank last?

Poly rainwater tanks are made of a UV treated food safe plastic, and should last upward of 10 years, with some poly tanks expected to last as long as 20 years before they start to destabilise, while Steel Water Tanks last well upward of 20 years, and as they are modular and repairable; can continue to be repaired for years after. Most Pioneer Water Tanks installed over 30 years ago are still in full operation to this day.

What is the average cost of a rainwater tank?

Rainwater tanks greatly vary in price based on material and supplier, and there is no typical cost – with a poly water tank setting you back anywhere between $750 and $5000 for storage between 5000L and 50,000L, and a steel liner tank setting you back between $4,500 and $30,000 for a wide range of sizes between 10,000L and 300,000L.

For a more accurate idea of pricing, you would do best to call around to a few installers, and get some quotes directly from them, allowing you to figure out what tank would be best for you.
