Greater Western Water (previously Western Water area) outcomes reporting

On 1 July 2021, City West Water and Western Water integrated to form business Greater Western Water. 

This page summarises Greater Western Water (previously Western Water area)'s performance against its outcomes, measures, and targets for the regulatory period 2018–23.

More details are available on our outcomes reporting page, and on Greater Western Water (previously Western Water area)’s website. 

What are outcomes?

Water businesses are accountable to their customers for delivering the outcomes set out in their price submissions, under our new PREMO water pricing framework. Each business is required to report at least annually to its customers on:

• it's performance against the specified measures and targets for each outcome
• an overall assessment of whether it has delivered on expectations for each outcome, including the business’s explanation for any performance shortfalls and how it intends to address them.

We have requested businesses also provide us with a summary outcome report document using a standard template. The self-assessments use a simple “traffic light” rating: 

• green = achieved target
• amber = mostly achieved target
• red = failed to achieve target.

2024 water price review

We are reviewing Greater Western Water's proposed prices and outcomes and determining the maximum prices it can charge for its water and sewerage services for the next 5-year regulatory period, from 1 July 2024.

Part of the price review includes assessing how it has performed against its outcome targets and major projects it committed to deliver to customers at the 2018 water price review.
