Project milestone
Our micro-Tunnel Boring Machine, Victoria, just aced her first 215m drive in Keith Hay Park's brand-new Branch 9B sewer! Starting in a trench seven metres ground, she bore on a gentle slope to finish 10m deep at the drive's end. The sewer links Mount Roskill's existing network to the Central Interceptor main tunnel, reducing discharges into Oakley Creek and setting the stage for future developments. She is now gearing up to head north along Keith Hay Park.
