Seqwater has awarded a major water infrastructure contract on a project spanning Toowoomba to Warwick that will include 64 waterway and seven rail crossings.
The $165 million 111 km water pipeline project in Queensland was prompted to strengthen long-term water security in the Toowoomba and Southern Downs regions following severe drought in recent years.
The Queensland Government’s south-east water utility, Seqwater, awarded the contract to the joint venture of CPB Contractors and energy infrastructure contractor, Nacap.
Stage 1 of the project will be completed up to Greenmount, 25 kilometres south of Toowoomba, which will deliver a permanent water supply to Cambooya, Greenmount, Nobby, and Clifton, and is expected to support 400 construction jobs, Seqwater stated.
However, Stage 2 of the project will provide drought contingency for Southern Downs communities in times of severe drought and will remain ‘shovel-ready’ to be delivered when it is required, according to the Queensland Government.
Project plans call for two reservoirs, two pump stations and two future offtake sites and will use ductile iron cement-lined (DICL) and mild steel cement-lined (MSCL) pipes as well as polyethylene pipes ranging in diameter from DN125 to DN600, ENR reported.
The route of the pipeline is largely located in state and local road corridors with the alignment including 64 waterway crossings and seven rail crossings. Work is set to begin later in 2026.
