The Northern Sewerage Project is on track to be delivered six months ahead of schedule.
Originally scheduled for commissioning in mid-2010, the Northern Sewerage Project will now be ready for use in early 2012, according to Victorian State Water Minister Tim Holding.
“This project is being delivered on budget and six months ahead of schedule,” Mr Holding said.
Victoria the tunnel boring machine (TBM) completed a 1.3 kilometre tunnel after breaking through a shaft in Coburg in late-February. Victoria has been excavating 24 hours a day, six days a week since December and has created a three metre diameter tunnel, approximately 30–40 metres below the surface.
Victoria is just one of three TBMs currently working on the Northern Sewerage project. Julia the TBM commenced her tunnelling activities in January 2009, whilst Gemma started tunnelling May 2008. Contractor John Holland has been working on the project since 2007.
The $A650 million project is being constructed in two stages and involves the construction of 12.5 kilometres of tunnel via tunnel boring to connect the sewerage system near Coburg and Pascoe Vale to the North Western Sewer in Essendon in metropolitan Melbourne, Victoria. The project will provide additional sewer capacity for Melbourne’s growing northern suburbs, including Epping, Lalor, Thomastown and Craigieburn.
