Geotech surveys underway

Published 21/08/2019

We're doing a series of underwater geotechnical surveys as part of working out the route and design for the Cross Harbour Pipeline

We are going to be carrying out a series of undersea geotechnical surveys in the Lowry Bay and Seaview areas, using a jack-up barge similar to the one used for the recent drilling near Matiu/Somes Island.

The undersea geotechnical surveys are an important part of determining the route and design of the pipeline that will cross the harbour providing Wellington with an alternative water supply improving emergency and operational resilience of our drinking water supply.

In the coming weeks you will be able to see the jack-up barge moving in and around the Lowry Bay and Seaview area, relatively close to the shore. So if you're around or live locally, you should be able to get a glimpse of the team at work as they drill a series of bore holes to establish the whereabouts of the undersea aquifer and its depth.

We expect to start the surveys late August, early September once we have confirmed a contractor.
