First tunnel boring machine launched
Published: 23 April 2021
This week our first mini tunnel boring machine (TBM), Izzy, launched at Trinity Marles Playing Fields.
In the tradition of naming tunnel boring machines after women , our project’s first mini TBM is named after ground-breaking project manager Isolde “Izzy” Piet.
Izzy the mini TBM has started her journey tunnelling 20 metres under Bulleen Road, the first of three TBMs to begin the task of building 1.8 km of new sewer.
Mini TBM #2 has arrived and #3 will arrive in the coming weeks. Their names will be revealed soon.
Tunnelling of the Yarra East Main Sewer will be complete by late 2021.
