We've examined every option. Here's our early thinking on where the water comes from, how it's used, and how we've designed to use less of it.

We expect to need about 140 million litres of water each year to run the facility.

Over the past year, we have explored different water sources that could support our operations, how it would be used within the power station, and how water use would be managed responsibly.

In this short video, Matt Poole, Project Manager, explains how the power station uses water, the steps taken to reduce water use, and how water would be managed over time.

How we use your input

Your input can help build an understanding of water uses and sources in the local area.

Your input continues to directly influence how the project develops, the design and the mitigations and management approaches to be outlined in the Modification Report*.

You can read more in the Explore water options information sheet.

*A Modification Report lets us propose changes to an already-approved project — updating what's permitted to reflect how the project has developed.
