Calculators

To help calculate the size of water tank you need, Bushmans has created a tank calculator that allows you to input your water usage details and find the right tank for you.

Choosing a rain water tank can be a difficult task. Not to worry, Bushmans is here to help save Australia’s water! We have developed Bushmans Water Tank Size Calculator to help you with this process. Deciding what tank you need has never been easier.

Your tank selection will be based on how much water you will need to store and the space you have available. Bushmans experts will ensure the tank will fit in with your home or building. So all you need to do is fill out the information in the chart below and we will calculate a general guide on what size tank you will need.

This Water Tank Size Calculator contains two tabs:

1) Water Tanks
Input your information about the roof area available and the average annual rainfall in your area (click here for the annual rainfall charts). The calculator will show your minimum rainwater tank size.


2) Water Usage
The water usage tab will allow you to calculate how much water you use a day on average.
You may be surprised to learn how much water is needed for everyday applications such as showering, brushing your teeth, flushing the toilet etc. It is always a good idea to try and minimise water wastage as much as possible – some examples would be only flushing the toilet with a half flush or making sure that the taps aren’t running constantly as you brush your teeth.
