Custom Water Tank Styles | Custom Water Tanks FAQs
We understand that different sites have different rainwater harvesting challenges. Sloping blocks might require a series of water tanks at different heights so they will balance / equalise properly.
A low set house on a large property might require squat tanks with a large diameter and low inlet height. You may have the space for a huge round water tank or be confined by having a narrow position for a slimline water tank. Whatever the challenges we will help find you the perfect solution.

Lisa Hagean
"I recently ordered a 7500 litre stainless steel round tank from Select Water Tanks and couldn't be happier with it. The process from order to delivery was perfect and I was kept in the loop with manufacture times and a set delivery date. Communication was great through the process and I had to change the delivery date to suit me and there was no issue with this.."
Gary Turner

"The team from Select Water Tanks were superb. The way they handled my new tank was especially careful and thorough. It was great watch them take it down a hill and locate on the site. Highly recommended for good product, service and interest in the customers needs."
Barbara Geitz
"We have just bought 3 tanks and have now installed them. We found Select Tanks very easy to work with right through to delivery. We had to change the delivery date on a number of occasions and it was never a problem. We are very happy with the quality of the tanks which look great."
Custom Water Tanks FAQs
Are rainwater tanks worth it?
Rain can be harvested from your roof for example, instead of flowing away from your property, via a pipe from the gutters for example into the top of the tank via an inlet strainer. If you approximate the cost of the tank as say $2500 and it is serviceable for over 30 years, then the cost is well less than $2.00 per week to provide water to your household, your stock, your crops or your lawn and/or garden.
Why stainless steel?
There are many reasons you should consider buying a stainless steel water tank.
They include:
- They come with a 30-year warranty for corrosion and so are cost-effective over time.
- The minerals used in stainless steel are valuable and so can be recovered and recycled.
- They are being designed into structures by builders and architects because they look good.
- University research shows they hold their structural integrity during a bush fire.
- Stainless steel keeps the water cool which helps reduce the growth of bacteria and algae.
- Stainless steel does not leech impurities into the water which makes it hygienic to drink.
Does Stainless Steel Cost More?
On average, round stainless steel tanks made from Premium grade 304 stainless steel are approximately $500 to $1000 more than the equivalent tanks made from Aquaplate/Colorbond.
For example, a 10,000 litre round tank made from stainless steel is approximately $1600 whereas a similar one made from Aquaplate/Colorbond is approximately $1000.
The price differential is slightly more for slimline tanks because of the inclusion of internal stainless-steel rods to strengthen the slimline shape of the tanks.
The price differential is also greater if Marine grade 316 stainless steel is used to construct the tanks.
For more information on pricing see our example price lists .
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.
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.
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.
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

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 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.
