Calculate average daily water usage

If you need to calculate the daily water use at your property or the average water used for a particular piece of equipment, our calculators can help.

This tool can calculate water usage charges since 1 July 2009. It doesn't calculate service charges or the total bill for your property.

Method 3. Calculate average daily water usage for certain days of use

Use this method if you have the total water usage but want to calculate it over a certain number of days rather than the full bill period. This is useful if your bill goes for 90 days, but you’ve been on holidays or own a business that’s closed on weekends.
