Prices and charges for business
Usage charges for 2024-25
Water plays a vital role in our lives. You may not think of us often, but we’re there when you turn on a tap, flush a toilet, make a coffee and run the water for your business.
To deliver this for you in 2024-25, we’re keeping price rises in line with inflation. Based on an average bill using 150 kilolitres of water per year, this means you’ll pay $12.43 more each quarter compared to last year. If you pay trade waste charges for your business, these have also increased in line with inflation.
With changes to our charges, we’re still investing in the future to deliver major projects that extend the life and efficiency of the networks that keep your services running.

Our charges and what your bill pays for
Most of what we do you’ll never see, much like the plumbing in your home or business. Here’s how we use the money you pay on your bill to provide reliable water and sewerage supplies for every customer.
This charge covers the amount of water used at your property, which is recorded by your water meter. We bill this per kilolitre (kl) of water used.
These are fixed charges for running, maintaining and repairing pipes and infrastructure that store, treat and deliver water to and take away sewerage from your property to treatment plants.
The water that goes down your drain, from the kitchen, bathroom, toilet and laundry is called sewage. This charge is calculated as a percentage of your water usage.
This charge covers the operational and maintenance costs associated with increased demand on the water network in the event of a fire at properties with a fire service.
