Western Australia's Premier Roger Cook has reversed his government’s stance on a proposed desalination plant at Esperance, now considering it as part of plans to secure water supply for inland communities. The state is moving forward with a $543 million upgrade to increase the capacity of the historic Goldfields water pipeline by 10% by the end of 2027. Previously, the government had dismissed similar proposals during the last election, but now acknowledges the potential need for desalination plants across the state due to both economic growth and climate change impacts.

In short:
Work has begun on a long-awaited $543 million upgrade to Western Australia's historic Goldfields water pipeline.
asserted
Work → begin → pipeline
The upgrades are designed to increase the pipeline's capacity by about 10 per cent and are due to be completed by the end of 2027.
What's next?
asserted
What → design → 2027
Early stage work is also progressing on plans for a proposed desalination plant at Esperance, which could potentially provide additional water capacity for the Goldfields.
uncertain
which → progress → Goldfields
The West Australian government is weighing up plans for another desalination plant on the south coast as work on a $543 million upgrade to the historic Goldfields water pipeline ramps up.
asserted
work → weigh → pipeline
Speaking at Kalgoorlie's Mt Charlotte Reservoir, where water from the Golden Pipeline first flowed in 1903, Premier Roger Cook said the upgrades would "futureproof" the Goldfields and Wheatbelt regions for generations.
asserted
upgrades → speak → generations
Mr Cook also conceded decades-old proposals for a desalination plant at Esperance, 700km south-east of Perth, could form part of plans to secure the water supply for WA's inland communities.
uncertain
proposals → concede → communities
It is a significant backflip for the government, which strongly criticised the WA Nationals for pushing the proposal during last year's state election.
asserted
which → criticise → election
"We looked very closely at the idea of a desal plant at Esperance and then piping it up to Kalgoorlie," Mr Cook said.
asserted
Cook → look → Kalgoorlie
"It was decided, through engineering design, that we were better off increasing the capacity of the Goldfields pipeline rather than building a whole new pipeline up from Esperance.
asserted
we → decide → Esperance
"I think we will need a desalination plant at Esperance.
asserted
we → think → Esperance
We will need desalination plants the length and breadth of this state, both as part of a growing economy and drying planet, so that's going to be an important piece of work.
asserted
that → need → work
"Whether you ultimately see a desalination plant in Esperance feeding the Goldfields region more generally or simply meeting the needs of the growing Esperance community, I think you will need desal there.
asserted
you → see → desal
During last year's election the WA Nationals promised to put $100 million towards an Esperance desalination plant to pipe water to Kalgoorlie-Boulder.
asserted
Nationals → promise → Boulder
But Labor's then-water minister Simone McGurk dismissed the proposal as "unviable" and a "thought bubble".
asserted
minister → dismiss → proposal
On Monday, Water Minister Daniel Pastorelli confirmed the government utility Water Corporation was in the early stages of planning for a desalination project at Esperance.
asserted
utility → confirm → Esperance
Construction is also progressing on two significant desalination plants in WA: the $2.8 billion Alkimos plant near Perth and the $1.1 billion Dampier plant in the Pilbara.
asserted
Construction → progress → Pilbara
Upgrades boost pipeline capacity
asserted
Upgrades → boost → capacity
The premier's comments about water security come after two key contracts, worth $170 million, were awarded in July to upgrade the capacity of the historic Goldfields Water Supply Scheme.
asserted
contracts → come → Scheme
The 566km-long pipeline was commissioned 123 years ago and supplies drinking water to more than 100,000 people across the Wheatbelt and Goldfields.
asserted
pipeline → commission → Wheatbelt
Mr Pastorelli said work on the pipeline upgrades are now underway, with about 44.5km of pipeline to be replaced through the Wheatbelt shires of Merredin, Westonia and Yilgarn.
asserted
work → say → Merredin
It is expected to increase the pipeline's daily capacity by 7.2 million litres, or about 10 per cent, by the end of 2027.
asserted
It → expect → 2027
Water demand rising
Mr Pastorelli said demand for water in the Goldfields had increased by 16 per cent since 2021, driven by the booming resources sector, and that the upgrades should satisfy existing demand "for some time" based on current projections.
asserted
upgrades → rise → projections
"This infrastructure will last … the pipes are being manufactured locally and will last for up to 150 years," he said.
asserted
he → last → years
"It goes to the strength of the economy that we're seeing that increased demand … this pipeline has lasted 120 years and we want to see it last another 100 years."
asserted
it → go → years
Mr Pastorelli said the government expected to award tenders in coming months for subsequent works at Binduli Reservoir near Kalgoorlie-Boulder, which would double its capacity from 400 to 800 million litres.
asserted
which → say → litres
Kalgoorlie-Boulder Mayor Glenn Wilson welcomed the investment in the pipeline.
asserted
Wilson → welcome → pipeline
"Water is a precious commodity here … none of us would be in Kalgoorlie without it [the pipeline]," he said.
asserted
he → say → it
"After many years where there wasn't much maintenance or love for the pipeline, it's great to see that investment … it will help grow our economy."
asserted
it → be → economy
The WA Nationals and the Shadow Minister for Water, Peter Rundle, who is based in Esperance as the member for Roe, have been contacted for comment.
asserted
who → base → comment
