Project Update: Arapuni Hydro Dam
Alton Drilling is currently working alongside Mercury Energy at the Arapuni Hydro Dam as part of a three-year infrastructure upgrade programme.
Using Rig 8586, our team is drilling a series of pressure relief holes into the dam’s left abutment. This work forms part of the contingency programme supporting the long-term performance and resilience of the asset.
The video below was captured during a helicopter restock, offering a unique look at the project and the environment our crew is working in.
A big shout-out to Driller Rory Lambert and the crew on site for representing Alton Drilling and continuing to deliver safe, high-quality work on this important project.
We’re proud to support Mercury Energy on projects that help maintain New Zealand’s critical infrastructure and renewable energy network.
