South East Queensland (SEQ) is one of the fastest growing regions in Australia and water security became a critical issue following several years of drought. The Northern Pipeline Interconnector (NPI) - Stage 2 project, as part of the south east Queensland water grid, is a vital piece of infrastructure which connects the previously segmented water zones of the Sunshine Coast region and SEQ. The pipeline has helped secure the water supply for SEQ through providing a fast and efficient transfer of water stocks between the regions.
The NPI – Stage 2 Project involved the construction of 48 kilometres of underground, reverse flow pipeline from Noosa to Eudlo, balance tank, four pump stations, a water quality facility and upgrades to an existing water quality facility. Upon completion the NPI – Stage 2 connected with the NPI Stage 1 to provide a 95 kilometre reverse-flow pipeline; allowing water to flow north or south between Brisbane and the Sunshine Coast and providing drinking water to existing storage facilities in Brisbane or the Sunshine Coast.
Following completion of the pipeline works in October 2010, Advisian was engaged to check that all defects were rectified and to ensure that the 250 landholders involved in the project were satisfied that their land had been restored to original condition.
Advisian brought to the project a depth of knowledge of the construction industry, cost and commercial expertise, capabilities in stakeholder management, and previous experience in major pipeline projects.
Through Advisian’s specialist commercial infrastructure knowledge and advice we were able to save LinkWater a substantial amount of the estimated capital cost.
The pipeline was successfully handed over to the client at the end of June 2012 following commissioning.
