Average rainfall in your state and recommended tank size
The average Australian household consumes around 250,000 litres each year. Of this amount, up to 125,000 litres can be used watering the garden and up to 75,000 litres for flushing toilets and operating washing machines.
So, depending on the size of your water storage and the number of people in your house, you can save up to 200,000 litres per annum.
