The Company is pleased to announce that McConnell Dowell Constructors (Aust) Pty Ltd, as a part of the Northern Network Alliance (NNA), has laid the last pipe of the 48 kilometre Northern Pipeline Interconnector (NPI) – Stage 2 project.
In another great milestone, the NNA Pipeline project has also just completed 500,000 man-hours LTI free, an exceptional safety achievement indicative of the dedication, planning and management of the project team to deliver this project safely.
NPI Stage 2 is the final component of both the south east Queensland water grid and McConnell Dowell’s six years of dedicated work to secure south east Queensland’s water supply.
McConnell Dowell has been at the construction forefront delivering this complex network of water transmission pipelines which connect South East Queensland’s dams, weirs and water storage facilities. This has included the following projects:
Northern Pipeline Interconnector Stage 2 - 48 kms of reverse-flow pipeline from the Noosa Water Treatment Plant to NPI – Stage 1 at Eudlo. Construction involved 2061 m of tunnelling, a new balance tank at Ferntree, four pump stations, and upgrades to existing water quality facilities.
Southern Regional Water Pipeline – a two way bulk water pipeline connecting Brisbane to the Gold Coast and moving water to where it is most needed through Ipswich, Logan and Beaudesert. SRWP achieved more than 2.5 million man hours, the laying of 94 km of pipe and construction of associated infrastructure, which included five pump stations, 10 tunnels, five elevated crossings, 25 auger bore crossings, four balance tanks and three water treatment facilities.
The Northern Pipeline Interconnector Stage 1 – 47 km gravity fed two-way bulk water pipeline transporting potable water between Morayfield and Landers Shute on the Sunshine Coast. 4155 m of offtakes to the Morayfield and Elimbah reservoirs were constructed including three bridges. The pipeline crossed 57 roads, 17 water ways and two rail lines.
The Eastern Pipeline Interconnector – An 8.4 km reverse flow bulk water carrier from Heinemann Road reservoir in Mount Cotton to Kimberely Park reservoir in Shailer Park. Infrastructure works included the construction of a pump station and a water quality facility.
The Western Corridor Recycled Water Pipeline – An 81 km pipeline system which included construction of two pump stations, two balance tanks and a tunnel under Bremer River. The pipeline connected the Bundamba waste water treatment plant and the Tarong Power Station intake at Caboonbah. Also in McConnell Dowell’s scope was construction of another 56 km of pipeline connecting town water pipelines to Toogoolawah, and 16km from Lowood to Logans Inlet at Wivenhoe dam.
McConnell Dowell has been a key member in the successful Alliance teams delivering these assets for LinkWater, Queensland’s Bulk Water Transport Authority who represent the Queensland Government.
This network, “the water highway”, is a critical piece of the Queensland Government’s emergency drought strategy. It will provide water security for millions of Queenslanders, giving the flexibility and capacity to move large volumes of water throughout the growing region.
As for NNA, a dedicated small team will remain into 2012 to finalise the project before handing it over to LinkWater Projects for operation and maintenance.
