• We use a tiered pricing system to encourage the careful use of water
  • The more water your use within a year, the higher the price per kilolitre
  • Your account will reset to the lowest tier annually

The water you use in your home and garden make up your water use charges.

We take a meter reading every 2 months to find out how much water you have used. You can find your water use since your last meter read on the back of your bill.

The front of your bill shows your current tier, based on your total water use this bill year so far.

Business customers: visit our business bill & charges page to learn about your water use charges.

How are water use charges calculated?

We have a tiered pricing system to encourage the careful use of water. The more water you use, the higher the price per kilolitre. Water use is measured and billed in kilolitres (kL).

Water use charge = Water use in kL for the period x current tier pricing

Water use charges vary depending where you live. Charges also work differently for properties that share a water meter, such as a unit complex.

Water use pricing tiers

Your account starts in tier 1 (the lowest tier) at the beginning of your bill year.  If you have recently moved into a property, you will start at tier 1.

If you have jumped to tier 2 or 3 within your bill year, you will revert to tier 1 when your new bill year starts. 

Check the front of your bill under 'Water use pricing' to see your current tier and when your bill year ends.
