A very productive couple of weeks on our Featherston, Whitmore & Bowen St Rising Main Upgrade project has seen us ram a pipe 50m across Lambton Quay. Amazing to think that a critical piece of this project has now been installed underneath the ground without digging any holes in this busy intersection!
The detail: We installed a 610OD steel casing with 14.3mm walls using a Grundoram Koloss by TRACTO-TECHNIK GmbH & Co. KG The casing is now ready for us to insert the 450OD PE100 SDR17 rising main through it.
Trenchless methods, such as pipe ramming, are a great way of reducing disruption to the travelling public, minimising risk associated with open excavations and keeping our carbon footprint to a minimum.
We are carrying out this project on behalf of Wellington Water and with support from our friends at Stantec.
