The Toowoomba to Warwick Pipeline is a proposed expansion to water services in Queensland's south-west, connecting water reservoirs between Toowoomba and Warwick. The scope of the project will be delivered over two stages.
The full scope of the Stage One works is expected to include:
- delivery of a 47-kilometre pipeline between Toowoomba and Greenmount
- connection to the existing Perseverance Pipeline prior to the Mount Kynoch Water Treatment Plant
- construction of two three-megalitre reservoirs at Highfields
- construction of offtakes at Greenmount and Westbrook for connection to future water treatment facilities, and
- construction of an intermediate pump station and balance tank.
Stage Two would comprise a 64-kilometre pipeline from Greenmount to Warwick. Stage Two remains subject to a future government decision and ongoing assessment of regional water security requirements.
The Pipeline will be owned, and operated by Seqwater.

PROJECT HISTORY
| Jan 2023 | The Queensland Government released its final investment decision for the Toowoomba to Warwick Pipeline, confirming the project has a total estimated cost of $370 million. The pipeline will be constructed, owned and operated by Seqwater and will deliver treated water to Warwick and the Toowoomba region. The project is scheduled to be completed by 2027. |
| Oct 2023 | Seqwater submitted the Environmental Protection and Biodiversity Act (EPBC) referral for the project. |
| Nov 2023 | Expressions of Interest opened for the construction contract, closing on 15 December. |
| Jun 2024 | The 2024-25 Queensland Budget allocated $56 million to the Toowoomba to Warwick Pipeline project in FY2024-25, with a revised estimated cost of $273.1 million. |
| Dec 2025 | Seqwater announced it is continuing to progress approvals under the Environmental Protection and Biodiversity Conservation Act. The project is subject to a Public Environment Report (PER), which will be assessed by the Commonwealth Department of Climate Change, Energy, the Environment and Water. Seqwater also announced that the construction contract award for the project is now planned for mid 2026, subject to approvals. |
| Mar 2026 | The Queensland Government announced that the project would progress through a staged construction plan. Stage One comprises delivery of work between Toowoomba and Greenmount, with Stage Two to deliver the remaining balance of work.

| Jul 2026 | Seqwater has awarded a CPB Contractors and NACAP Joint Venture the contract to deliver Stage One of the project. Stage One has an estimated total cost of $223 million and will transfer raw water from upstream of the Mount Kynoch water treatment to Greenmount. The project will comprise 47 kilometres of open-trenched pipeline, and construction of two reservoirs at Highfield and offtakes at Westbrook and Greenmount. Stage One is expected to commence construction in late-2026 and be completed by the end of 2028. |
