Frequently asked questions

About the Rookwood Weir project

What is the Rookwood Weir project?

The construction of Rookwood Weir will capture valuable water in the lower Fitzroy River, which will enable landholders to transition to higher value agricultural land use, facilitate new industrial business opportunities and provide future water security for the region.

The project will require the construction of a new bridge upstream of the weir at Riverslea, plus upgrades to Thirsty Creek Road and the Capricorn Highway intersection at Gogango to ensure the local road network can safely manage weir construction traffic.

Where will Rookwood Weir be located?

Rookwood Weir will be located in the lower Fitzroy River, 66 kilometres south-west of Rockhampton.

Who is funding the project?

The $352 million Rookwood Weir project is jointly funded by the Queensland and Australian governments.

What is the full supply volume of the weir?

Upon completion, Rookwood Weir will be the largest weir operated by Sunwater in regional Queensland.

Subject to final design, the weir’s full supply volume will be approximately 65,400 megalitres (ML) and will yield up to an estimated 76,000 ML of medium priority water – subject to final design in September 2020.

Who will use the water from Rookwood Weir?

The Rookwood Weir project will provide water security for urban water supply to Livingston Shire Council and Gladstone Water Authority Board, plus stimulate economic growth through high-value irrigated agriculture and industrial business opportunities. The majority of the water will be available through the purchase of a water allocation for agricultural use through the Rookwood Weir Water Sales program.

What is the timeframe for the construction / operation of Rookwood Weir?

Early works are expected to commence in late 2020 with major in-river construction commencing in April 2021. Construction is expected to take up to three years to complete (subject to approvals and weather permitting), with operation of the weir commencing in 2023.

Who will construct Rookwood Weir?

The design and construction of the weir will be managed by:
• Sunwater – construction authority, operator and water marketer
• GHD – designer
• McCosker Contracting and Lendlease Engineering – constructor.

Why has the height of Rookwood Weir been lowered?

The original Rookwood Weir proposal was for a gated structure that was significantly more expensive to build than first estimated.

To achieve maximum water yield and deliver the project within the $352.2 million budget, a decision was made in August 2019 to change the design from a gated to an ungated structure. 

The following design requirements had to be managed with the budget available:

  • improved design structural integrity (hydraulic modelling)
  • the size and complexity of the fish locks, resulting in additional structural requirements (35 per cent more concrete)
  • EIS and environmental offset costs.

Who will own the weir?

The Queensland Government will own the weir for up to five years post-construction. During this time, the weir will be operated and maintained by Sunwater. At the completion of this period, the weir will be transferred to Sunwater’s ownership.

Both the Queensland and Australian governments have committed to fund the project and Sunwater is the State entity responsible for the construction and operation of the weir as well as marketing and sales of the water.

What is the project timeline?

Sunwater immediately commenced preparatory activities for the Rookwood Weir project when it was appointed construction authority, marketer and operator by the Queensland Government in July 2018. This included establishing a dedicated project team.

A number of road upgrades to enable construction of the weir are underway, including the Capricorn Highway intersection upgrade at Gogango and the upgrade at Thirsty Creek Road. A tender to upgrade Riverslea bridge will be awarded in June 2020.

Land and environmental approvals are progressing, while a request for Environmental Impact Statement (EIS) extension has been submitted and approved. A revised Social Impact Assessment was submitted to the Coordinator-General’s office in early May 2020 for approval before works commence.

Sunwater is on track to enter into the alliance for the main weir package by September 2020 with early works commencing in late 2020.

Construction is expected to be completed and weir commissioned and operational by end of 2023.

Why is water from Rookwood Weir going to Gladstone?

While the final yield of water available from the weir is yet to be determined (estimated to be up to 76,000ML MP), no matter the outcome, the majority will be for local landholders and agriculture.

That said however, one of the key considerations and justifications for building the weir was to provide water security to the region (including Gladstone). The Gladstone Area Water Board made a commitment to take water from the weir to supplement its supplies from Awoonga Dam and improve the reliability of water supply to the people and industries in the Gladstone region. The project was given the green light to proceed based on this commitment.

Will a pipeline to Gladstone be built as part of the Rookwood Weir project?

Sunwater, as the construction authority, is building Rookwood Weir to capture valuable water from the Fitzroy River for region. Any associated pipeline infrastructure is not within the scope of the project. The Gladstone Area Water Board is progressing work on the water delivery pipeline from the Fitzroy River to Gladstone.

Sale of water from Rookwood Weir

How much water will be available for landowners?

We are working to maximise the yield available from Rookwood Weir, considering both high priority (HP) and medium priority (MP) water.

Through the Water Sales program there will be opportunity to secure water lots of 500 megalitres (ML) and greater (maximum of 30,000 ML available) in late July 2020 or an expression of interest (EOI) process to work with Sunwater to secure smaller water lots in 2022 (minimum of 7,500 ML of MP available).

How can I secure a water allocation?

Sunwater invites landholders and investors to discuss their water needs and the opportunity to secure a water allocation from Rookwood Weir.

Sunwater is proposing to sell water from Rookwood Weir through a two-step process:

  1. Tender One water sales process for lots 500 ML and greater will be held in late July 2020 (maximum of 30,000 ML available)
  2. An Expressions of Interest (EOI) process to work with Sunwater following Tender One in preparation for a second tender of smaller lots (Tender Two), which is expected to be held in 2022.

Landholders interested in securing smaller water lots are encouraged to complete a Registration of Interest Form to participate in the EOI process.

If you would like to register your interest today, email rookwood.weir@sunwater.com.au or phone 1800 423 213. Registrations close on 23 June 2020.

How much will the water cost?

The price of water from the weir takes into consideration many factors, including amendments to the water plan, ongoing operational costs, and the cost to closely manage, monitor and mitigate any risks to the environment.

Sunwater is currently working through these variables with the Department of Natural Resources, Mines and Energy and a price will be available when Invitations to Tender for Tender One are released in late June 2020.

Sunwater can guarantee that the cost of building the weir will not be a factor in determining the cost to purchase a water allocation.  Operational and maintenance costs post-construction will be used to determine the ongoing charges for water allocation owners (i.e. Part A and Part B).

The water plan for Fitzroy Basin

How can I provide feedback on the changes to the water plan?

The Queensland Government has been seeking public feedback on the best options for allocating Rookwood Weir water under the Fitzroy Basin water plan.

For updates on the water planning process, please visit the project page.

Business opportunities

Where can I register my business to secure work on the project?

Sunwater has partnered with the Industry Capability Network (ICN) to connect contractors, subcontractors and suppliers with project opportunities. Local industry operators interested in the project are encouraged to register their interest at our ICN supplier portal: http://rookwoodweir.icn.org.au
