Project
Pareroa Gorge Pipeline
Region
Christchurch, Timaru
Client
Timaru District Council
Completed
2019

DO conducted a geological investigation of the Pareora Gorge, a significant project for the Timaru region given this involved the primary water supply for the city. We assessed the geology of the area traversed by the proposed pipeline culminating in a project specific engineering report.

 

The team crucially assessed ground conditions along the 2.8 km pipeline alignment, mapping key geological features like Tertiary-Permian unconformity and a high-risk landslide area.

 

We identified critical geotechnical risks in the multi-million-dollar pipeline upgrade, effectively communicated risks and mitigation measures to TDC. By keeping them informed, we helped them to make decisions. Our advice led to substantial savings by opting for a more economical solution.

 

This project showcases DO’s expertise and transparent communication approach, fostering close collaboration with both the Council and tunnelling contractor Hadlee and Brunton.
