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.

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”

How long does it take for the Tanks to Arrive?

It normally takes about three weeks to make your tank and have it ready for delivery.

In very busy periods however, it can sometimes take up to 7 or 8 weeks to have your tank ready for delivery. Please check with our Office Manager the likely delivery time for your tank, given the current work load at the time of order.

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 .

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.

What are the delivery costs?

Our Office Manager will discuss with you the cost of delivery. The delivery cost is primarily based on the distance from our factory south of Brisbane to your site. Other factors which may need to be taken into consideration for example, are the size of the load and the difficulty of access to your site.

Will you position the tank(s) on site?

Yes we can position your tank(s) on to a concrete slab, a crusher dust pad or a timber platform provided they are built correctly to fit the size of tank ordered.

We can provide one or two men if needed but you will need to provide additional staff if the tank is very large or it is a particularly difficult site to access.

If a crane is needed, we can liaise with the crane company.

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.
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.

Do the tanks meet Council Overlay requirements?

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

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.

How are tanks delivered?

Our usual delivery mode is on either a small truck, truck and trailer or 4WD ute and trailer. The round tanks are rolled off onto mattresses which protect the tanks, whereas the slimline tanks are carried or put onto small trolleys for manoeuvring and then depending on the site access being suitable, rolled or manoeuvred close to the prepared tank base.

A geofabric cloth is put down onto the prepared base, then the tank is stood onto its bottom on the prepared base. The tank can then be moved around to the correct positioning.

Depending on the size of the tank some onsite assistance will be required. It is best to discuss any site complications or delivery queries when ordering your tank.

I purchased an 5000L aquaplate tank and pump kit. The advice and follow from Linda and the team was great in helping me determine the best tank and then the delivery team were really helpful as the access wasn't ideal. However everything worked really well and the communication and follow up through the process was much better than some others i tried.

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.

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. I was contacted the day before delivery and then on the delivery day with a rough time and when they arrived I was greeted by two happy strong men who were more than accommodating in helping to situate my new tank through a tricky low carport and onto the tank pad. They even put a geotextile sheet over the gravel I had in the tank pad in case the iron in the rocks reacted with the metal tank. The tank is beautiful and adds to the aesthetic appeal of my kitchen garden. Would definitely recommend to others!
