IPART sets maximum prices for Greater Sydney water users

We have published our Final Reports

IPART has released its final decisions on how much Sydney Water and WaterNSW can charge for water and related services in the Greater Sydney region from 1 October 2025.

Under our decisions, a typical household’s yearly Sydney Water bill for water and wastewater services would increase by 13.8% or $168 in 2025-26 including inflation, and then by around 5.1% or $77 each year plus inflation until 2030.

The maximum prices we have set provide Sydney Water and WaterNSW with an average of $548 million and $36 million respectively in extra revenue each year to deliver safe and reliable services for customers throughout Greater Sydney. This allows service capacity to keep pace with Sydney’s growth, meet community expectations on social and environmental performance and deliver value to customers. It also means customers will pay only for Sydney Water’s costs we consider to be efficient in delivering its services.

We thank all stakeholders for their time and effort taken in providing their views on Sydney Water and WaterNSW’s prices. We considered all feedback from stakeholders in making our final decisions and recommendations.
