Colorbond / Aquaplate Water Tanks

Match your Colorbond Water Tank to Your Property

They are a perfect choice for those wanting to colour coordinate the tank to your property. They can be built to colour match or contrast to your fence, shed or an external painted wall. The colorbond tanks can be manufactured in either the round style with capacities from as little as 190 litres up to a huge 29,800 litres or the slimline shape with water storage from 150 litres up to 8,523 litres.

Select Water Tanks custom build each tank to order, which gives our customers the best tank to suit their requirements. The tanks come with 3 standard inclusions: A 400mm Inlet Strainer and Light Guard, a 25mm Outlet with Ball Valve, and a 90mm Overflow with Stainless Steel Gauze, which can be positioned to your requirements. Additional fittings, like the firefighting fittings: Camlock for Qld or the Storz for NSW, a bucket height tap or additional 25mm or 50mm outlets and ball valves, can be added to the tank to meet your needs.

With the classic galvanised or coloured corrugated finish on the round or slimline tanks they are well suited to a range of properties from the modern, contemporary, colonial, beachside, or rustic styles.

Being manufactured from steel, the tanks can be made to meet council requirements for firefighting purposes, be incorporated into a whole of house rainwater harvesting system, or to have as your very own water supply in times of need. Your own harvested water supply is so beneficial if you love to garden, keep your car sparkling or just lower your council water bills. In times of water restrictions, you will still have your own water supply to use for your property, and by lowering the demand on the council or town supply water, you can save some money too.

Why Aquaplate / Colorbond?

Aquaplate/Colorbond tanks are slightly less expensive than ones made from stainless steel and they come in a range of colours to match or compliment existing structures or colour schemes. These tanks come with a 20-year warranty for corrosion and a 10 year manufacturers warranty. Research has shown, that they keep their structural integrity during a bush fire.

Do you connect the tanks up?

No. We suggest you get a local plumber to connect them up. That way you have a local expert to make them compliant to local conditions.

Are the tanks resistant to bush fires?

Yes. University research shows that both Stainless steel and Aquaplate/Colorbond tanks maintain their structural integrity during bushfires.

What other fittings are available?

There are a wide range of additional fittings we can provide. One example is we can install a bucket height tap on the side of your tank.

How do I work out the size of tank I need?

Normally we recommend that you get the largest size tank you can to suit your site. Round tanks can be made to much larger sizes whereas slimline tanks can be made specifically to fit neatly into a confined space.

Deciding a size can be influenced by a number of factors. These include:

  • The number of people living in a house if it is for domestic use
  • The catchment area of the roof
  • The annual rainfall

For more information visit our “Custom Shapes & Sizes Section”

Do the tanks meet Council Overlay requirements?

Yes we can build the tanks to meet specific Council Overlay requirements.

What fittings come with the tank?

Three fittings come with your tank. You will be asked where on each tank you want them.

They are:

  • A 400mm inlet strainer with light guard which allows the water from your roof for example, into the tank, with protection from the sunlight and mosquitoes.
  • An overflow attachment which is a round plastic outlet which can be either 90 or 100mm in diameter and which come with mosquito proofing.
  • A 25mm outlet with a ball valve located at the bottom of your tank.
Can the tanks be made to be fire-fighting compliant?

Yes we can fit the tanks with the required fittings to make them firefighting compliant,  with a Storz fitting for NSW or the Camlock for Qld.

One particularly efficient tank we can build is where the normal outlet system is built a certain distance up the side of the tank so that you always have 10,000 litres in the bottom section of the tank in case of fires, while still using the water in the top of the tank for normal use.
