Our annual water performance report compares the performance of Victoria’s urban water businesses against each other.
Water performance reports
Overview
We compare trends in performance over time in a number of key areas. Our report aims to:
- inform customers about their water business
- provide incentives for water businesses to improve their performance.
Following the end of each financial year, businesses collate their performance data and send it to us. We request comments from businesses to explain significant changes in their performance and include these in our report.
Normally the data businesses provide us is independently audited, however for our 2019–20 reporting, we removed this requirement to lower the regulatory burden placed on businesses, allowing them to focus more closely on supporting customers during the pandemic.
We resumed our audit program in 2021 which included an audit of 2019–20 data.
We’re required to undertake performance reporting by the Water Industry Regulatory Order 2014, in accordance with our performance reporting framework and our regulatory audit guidelines.
For each reporting year, you can find:
- our annual performance report
- a summary sheet for each business
- a data spreadsheet
- the definitions for our performance indicators.

Key findings from the 2022-23 report
Victorians used less water
In 2022-23 Victorian annual household water consumption decreased by 5.9 per cent. In Metropolitan areas consumption decreased by 5.3 per cent, and in regional areas consumption decreased by 7.3 per cent.
Bills received by water business customers remained relatively steady
In Metropolitan Melbourne, the typical annual owner occupier bill decreased by $18, however in regional Victoria it increased by $18. The typical annual bill decreased for tenants in both regional Victoria ($7) and Melbourne ($22).
Water businesses continued to support customers
Victorians have been impacted by increased cost-of-living pressures and flooding in parts of the state.
Overall, more customers received hardship grants, state government Utility Relief Grants, and had concessions applied to their water accounts as water businesses continue to support customers.
However, differences in customer approval rates for Utility Relief Grants indicate varying levels of assistance provided by water businesses. Businesses with lower application and approval rates should explore ways to improve customer access to these grants.
