Regional Queensland is one step closer to long-term water security, with the first water flowing into the Fitzroy to Gladstone Pipeline as testing continues.
The Fitzroy to Gladstone Pipeline (FGP) is more than just a pipeline – it’s a carefully engineered system designed to deliver water efficiently and reliably to the Gladstone region.
A key part of this system is a network of valves installed along the 117km alignment. These valves manage water flow, maintain pressure and support safe operations across the entire pipeline.
A variety of valves have been installed to ensure the FGP operates smoothly when it comes online in 2026:
- Butterfly valves – used to control water flow through the pipeline with minimal resistance.
- 800mm control valve – located at the Gladstone Area Water Board (GAWB) network connection at Mount Miller, serving as the master control point.
- DN750 isolation valves – spaced approximately every 10km, allowing sections to be isolated for maintenance or emergencies.
- Scour valves – placed every three kilometres at low points to help remove trapped air and assist with efficient water filling.
- Air valves – located at high points every kilometre to release air and support system filling during commissioning.
Each valve plays a specific role, but together, they form a critical part of the FGP’s operation.
With installation nearing completion, Principal Contractor McConnell Dowell BMD Joint Venture has begun testing sections of the pipeline.
First water flows into the pipeline
Water has now been pumped into a section of the new pipeline as part of testing prior to completion in 2026.
GAWB CEO, Darren Barlow, said the milestone marks significant progress for the $983 million project.
“This is the first time water has flowed through a section of the new pipeline, and it’s an exciting sign of what’s to come,” Mr Barlow said.
The FGP comprises a 117km pipeline (now almost completely constructed), reservoirs and a water treatment plant, all of which are progressing well.
As each component is built, it undergoes rigorous testing to ensure safe and reliable operation during commissioning in 2026. Around 3km of pipeline has now completed hydrostatic testing – a key process that involves filling the pipeline with water and pressurising it to check for leaks or weaknesses.
“Hydrostatic testing is a vital step in confirming the safety and reliability of the infrastructure before it is brought into full service,” Mr Barlow said.
“Reaching this stage is a testament to the skill and commitment of our project team and partners. It brings us one step closer to delivering a secure water future for Gladstone.”
Progress across key sites
Construction is advancing across all major components:
Laurel Bank Intake
Key structural elements are now in place, with backfilling completed around the pump station and preparations underway for mechanical installations. The earthing grid for the control building is being installed to support the next stage of electrical works.
Alton Downs Water Treatment Plant
Clarifier wall pours are nearing completion. Mechanical and electrical crews are preparing for the next stage of fit-outs, while roofing is progressing on the control and administration building. At the silt dewatering facility, wall cladding continues, and preparations are being made for final concrete pours and equipment installation.
Aldoga Reservoirs
Each of the two reservoirs will hold up to 50ML, enough water in each to fill around 20 Olympic-sized swimming pools. All 120 precast concrete wall panels have been installed and stitched together for a watertight structure, and internal support columns for the roofs are complete.
Supporting regional water security
Construction of the pipeline remains on track for completion in 2026, weather and conditions permitting. The FGP will provide a second source of water to Gladstone, reducing long-term supply risks from Awoonga Dam and supporting the region’s industrial growth.
GAWB, as a Queensland Government Bulk Water Supply Authority, delivers safe and reliable water services that promote economic development and enhance the lifestyle of regional Queensland. GAWB owns and operates Awoonga Dam, along with a network of pipelines, water treatment plants and other distribution infrastructure. GAWB also owns and operates Aquaculture Gladstone, a fish hatchery and interpretive display at Lookout One at Lake Awoonga.
To ensure long-term water security for customers, the 117km FGP is under development. When delivered, the FGP will become part of the GAWB network and provide enhanced water security and reliability for the region.
