Calculating water rates
All invoices are calculated on the number of days in each invoice period, and water used is charged for at a:
- volumetric rate (per cubic metre (1000 litres))
- fixed annual charge per separately used or inhabited part of a rating unit.
There is no 'free' allowance of water in the annual fixed charge, and it applies to each separately used part of a rating unit (ie, a home and a granny flat).
You can estimate your own water use – see Estimating your water costs.
