Domenica achieves another milestone

Our micro tunnel boring machine (mTBM) recently completed her second of four drives on Link Sewer C, from Dundale Avenue to Haycock Avenue. Domenica’s journey of 715m was completed in 83 days as she laid 249 pipes. She is now at our May Road site for refurbishment, where we are readying her for the next drive, from Dundale Ave to Miranda Reserve in Blockhouse Bay Rd.
This journey is some 1200 metres, much longer than her last two. This is because CI was able to pass beneath the location of a previously planned site, in Whitney St, New Windsor. No longer needing to excavate a shaft in this street has eliminated what could have been substantial disruption to that local community.
