GWMWater outcomes reporting

This page summarises GWMWater's performance against its outcomes, measures, and targets for the regulatory period 2018–23. This is the final year of reporting against its 2018 commitments, with its new outcomes, measures, and targets in effect from 1 July 2023.

More details are available on our outcomes reporting page, and on GWMWater’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.

2023 water price review

Our 2023 water price review assessed 14 water businesses’ proposed prices and outcomes and determined the maximum prices these businesses can charge for their water and sewerage services for the next 5-year regulatory period, from 1 July 2023.

Part of the price review included assessing how businesses have performed against their outcome targets and major projects they committed to deliver to customers at the 2018 water price review. In our final decisions, we agreed with all 14 businesses self-assessments that they had, overall, met their outcome commitments for the 2018–23 period, and that their reporting to customers during this period met our requirements.
