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.

Water Tanks Questions

1. Where should I put my rainwater tank?

The first thing you will likely look at when thinking of installing a water tank is where you will have the available space to do so. Pioneer’s Water Tank Installation page has a table showing the required sand pad size for the available water tank sizes.

As well as having room for the tank, you have to ensure that your tank is adequately low enough when compared to your gutters in order to effectively harvest rainwater from your roof. To ensure that all collected rainwater makes it into your tank water, the inlet of your tank should be located 50mm below your gutters for every 1000mm away from the home the tank site is located.

Your water tank should be installed away from trees or overhanging branches, and in a location easy to access for maintenance or cleaning.

2. What is my rainwater tank made of?

There are a variety of materials that water tanks can be constructed from, as well as a range of companies with different design specifications when it comes to their engineering and manufacturing.

When it comes to strength and durability, nothing beats a steel water tank. Contrary to belief, galvanized tanks do not offer complete corrosion protection, which is why Pioneer utilizes Zincalume ® and Colorbond ® Steel, proven to last up to four times the life of galvanised steel.

Tank panels should be manufactured between 0.8mm to 1.2mm thick. Thicker does not always mean better, a thicker panel will weigh more, and place additional strain on the tank structure. Pioneer Water Tanks have been designed specifically for water storage, and the Pioneer V-Lock® tank wall profile won an Australian design award for its engineering and aesthetic appeal.

3. What is on the inside of my tank?

If you choose to go with the strength of a steel water tank, getting the right water tank liner is vital when it comes to keeping your precious rainwater clean and fresh for you and your family. It is recommended that you choose a liner that is made from a multilayered and reinforced polyethylene fabric, with double welded polyethylene seams, and meets all requirements for products that come in contact with drinking water. This will ensure that your tank has the internal strength and durability to provide you and your family with clean and pure drinking water for generations to come.

Pioneer Water Tanks lead the way when it comes to water tank liners, with our exclusive Aqualiner Fresh® antimicrobial water tank liner, which goes beyond the  Australian Standards, and includes silver ions woven into the liner to prevent the growth of algae or bacteria within your tank, helping keep your water fresher for longer.

4. What after-sales service will I receive?

A water tank is a significant investment that requires careful consideration. Not only do you want to ensure that you are purchasing a high-quality tank, but you also want to know that you can rely on the company and its distributers for ongoing support and servicing. This is why Pioneer Water Tanks is committed to providing the best after-sales care to our customers, along with our 20 year conditional structural warranty.

5. What size rainwater tank do I need?

What size rainwater tank you need will depend based on your requirements, but if you are looking for a rainwater tank for your home, Pioneer’s rule of thumb is that you need a base 50,000L of water storage for a single person, plus an additional 30,000L for every additional person living in the home – you may need more for your garden or pets.

If you are able to install a larger tank – if it fits within your budget, available area, and your rainwater harvesting ability – you are encouraged to do so, as it is always better to have too much water than not enough. Pioneer Water Tanks are available in a range of sizes from 12,000L to 500,000L, meaning no matter your water storage requirements, there will be a tank that meets your needs.

6. Can I collect water directly from my tank?

Another way that Pioneer continues to lead the way in water is with our innovative yet simple Smart Water Savers.

Developed by a member of the Pioneer Family, the Smart Water Saver uses clever thinking and futuristic innovation with a patented design that harvests water straight from your tank roof without the shortfalls that came with traditional methods of collecting water from a tank roof.

Where gutter systems are prone to collect debris and lead to contaminated water, the small 1.2mm slots of the Smart Water Savers allow debris to pass right over, while the water falls into your tank – increasing your rainwater harvesting ability by up to 25%!

7. How much rainfall can I harvest?

The equation for how much rainfall you can harvest is a simple one, provided that you have the numbers ready.

You will need your average annual rainfall (if you know your property’s average, even better, as your microclimate may be different to surrounding areas), and your total rainwater harvesting area (this will be the roof of your home, plus any sheds you have guttering on).

Average Annual Rainfall (mm) x Rainwater Harvesting Area (m²) = Rainwater Harvesting Ability (L)

8. What accessories will I need for my rainwater tank?

If you are purchasing a steel water tank, it will likely come with a range of standard accessories, which may include things such as an access hatch and ladder, as well as a set of anodes. Poly tanks often don’t include accessories making them somewhat of a hidden cost.

As well as the standard accessories, however, many people look for additional accessories to make their tank more fit for purpose, such as a dust seal, water level indicator or smart tank monitor. For Pioneer’s list of water tank accessories click here.

9. What colour do I want my rainwater tank to be?

In addition to a range of available sizes, your water tank will be available in a range of colours – either coloured plastic for a poly tank, or Colorbond® colours for steel water tanks.

Pioneer believes that your water tank should be a feature of your home, not an eyesore that you try and hide, which is why – along with an aesthetically pleasing design – Pioneer Water Tanks are available in a range of standard and non-standard Colorbond® colours.

10. Will I be using my rainwater tank for bushfire protection?

Western Australia is a particularly hot and dry part of the world, where even the wettest parts of the state like Pinjarra, or the coolest parts like the Albany region, experience reasonably frequent bushfires.

Many Western Australians take precautions by installing an additional rainwater tank, or by increasing their water storage capacity in order to ensure they have available water supply for bushfire protection. If you are going to be using your water tank for bushfire protection, you may choose to install a fire reserve, or at the very least increase your overall water storage capacity.
