  Diverting the North Yarra Main Sewer - Making Way for the West Gate Tunnel

  The West Gate Tunnel Project (WGTP) is a significant piece of infrastructure being delivered by D&C Contractor CPB John Holland Joint Venture for the Victorian Government and Transurban, in Melbourne, Australia. The project will deliver twin tunnels under Yarraville, a new bridge over the Maribyrnong River, a widened West Gate Freeway and enhanced interchanges. The diversion of the North Yarra Main Sewer (NYMS) is a critical component in the realisation of the WGTP. The 130-year-old brick lined sewer intersects with the future 15.6m diameter Earth Pressure Balance Machine (EPBM) driven twin WGTP tunnels and as such, required re-routing. The new 636m length sewer diversion was constructed in two drives from 3.0m outer diameter Glass-reinforced Plastic (GRP) pipe via trenchless methodology using a Slurry Shield TBM, making it the largest diameter GRP pipe-jacked tunnel in Australia.
