Household water use varies enormously depending on the number of people in a house and their personal needs.

How much do you use?

Our Waterwise table below will help you understand your annual usage.
You can monitor it by comparing it to the volume record on your water bill.
This will help you keep an eye on costs and identify leaks or any other problems you may be responsible for.
