Keeping our prices fair and transparent
We have a responsibility to everyone who lives and works in Greater Sydney to efficiently manage the infrastructure for drinking water, recycled water, wastewater and stormwater.

How prices are set
IPART (the Independent Pricing and Regulatory Tribunal) determines our prices every 5 years.
- The process starts when we provide a price proposal outlining our proposed costs to service customers efficiently for the next 5-year period. The proposal includes the costs to maintain our existing networks and any projects or initiatives in the next period. These might be new treatment plants, upgrades to our infrastructure, community or environmental programs. We run a customer engagement program to ensure our proposal aligns with what is important to our customers and what they are willing to pay for because customer bills are our main source of funding.
- IPART then reviews our proposal. It publishes our proposal on their website and asks for public consultation. This gives everyone from residential and business customers, to local councils, to big development companies and even government departments, the chance to read and comment on the proposal.
- IPART reviews all of this information before providing a draft of our prices for water, wastewater, recycled water, stormwater and other services.
- Then the public consultation process starts again. We also get an opportunity to respond to their draft with any issues we think might come from the prices they've suggested. IPART reviews all the feedback and provides a final determination (the prices) and report (their reasons).
The whole process usually takes about a year. The prices you pay depend on the type of property and the services available in your area. They're adjusted for inflation each year on 1 July.
IPART issued its final decision on our pricing for 2025–30 for our prices that apply from 1 October 2025.
