Thousands of Custom Sizes Available

Different sites have different rainwater harvesting challenges.  Sloping blocks might require a series of water tanks at different heights so they will balance properly.  A low set house on a large property might require squat tanks with a large diameter and low inlet height.  Whatever the challenges Select Water Tanks will help find you the perfect solution.

Jumbo Stainless Slimline

This customer needed 20,000 litres on a long skinny block in Paddington.

Under The Deck

Under deck tanks are perfect for sloping sites.

Commercial Water Tanks

Water tanks for industry with commercial fittings.

Space Saving

Aquaplate Slimline Water Tanks are perfect for wash bays in high traffic areas.

Slimline Water Tanks

Slimlines are perfect for narrow blocks or yards without a lot of space.  They can fit down the side of a garage or shed without stealing too much real estate.

Select Water Tanks can manufacture down to a minimum width of 550mm for very tight spaces.  It’s important to consider the height of a very slim water tank.  As a general rule, the tank should not be more than 3 times as high as its width.

 

  • Length Increments:  100mm
  • Width Increments:  50mm
  • Height Increments:  76mm (approx)
  • Common Heights:    1255mm, 1560mm, 1860mm, 2350mm.

Round Steel Water Tanks

If you have the space, a round water tank is by far the best value for money. Round water tanks do not require additional reinforcing, as Slimlines do, so they cost less to manufacture.  They are also easy to clean and maintain.

Select Water Tanks can manufacture a round water tank up to almost 37,000 litres.  Measuring 3900mm in diameter x 3100mm high, this tank requires a crane to position.  Alternatively, we can manufacture a tank that you could fit in the back seat of your car.

 

  • Diameter Increments: 100mm
  • Height Increments:  76mm (approx)
  • Common Heights:  1255mm, 1560mm,1860mm, 2350mm, 2800mm, 3100mm

How Do I Know What Size Water Tank I Need?

Download Our Rainwater Harvest Yield Graphs and Information based on the assumptions below.

It can be difficult to know just how much water storage capacity you might need for a whole-of-house rainwater harvesting system.  There are several factors to take into consideration:

  • Number of occupants in the household
  • Average rainfall in the area
  • Size of catchment (roof area)
  • Available space on site
  • Budget

Let’s start with a few assumptions:

  • 45,000 litres of total capacity is a good starting point for a whole-of-house rainwater harvesting system
  • A catchment size of 250 square metres
  • The average daily water usage per person is between 150 and 200 litres. Some geographical areas report higher usage.  At the higher end of the scale, a family of four would use approximately 24,000 litres per month.
  • Monthly average rainfall figures for a certain area are widely available on the internet. For this exercise we are researching monthly rainfall in Currumbin Valley, Qld.  These figures are available at  http://weather.mla.com.au/climate-history/qld/currumbin-valley

The relationship between the catchment size and rainfall is key to determining the desired capacity of your system;

10mm of rain on 100m2 of catchment will result in 1,000 litres of harvested rainwater

Other factors including evaporation, absorption, first flush diverters, or gutters full of debris are not accounted for in this example.

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!
