Latest Updates
We’re one step closer to completing the laying of the new water main to Titahi Bay.
We've laid more than 760 metres of pipeline and are about to hit a milestone!
We’re making good progress on replacing the Titahi Bay water main, which will secure and future proof the delivery of safe drinking water for the entire Titahi Bay Peninsula
The pipe will be replaced in two stages.
Stage 1, from Elsdon Park to the northern end of Tangare Drive, in the Titahi Bay Road and Tangare Drive road corridors, starts 15 January 2024.
Stage 2, across to Whanga Crescent, is in the design stage. In April 2023 geotechnical investigations were undertaken on Titahi Bay Road, Tangare Drive and Whanga Crescent.
Why are we doing this?
The existing Titahi Bay trunk water main is a 225 mm asbestos cement water main laid in 1963.
This work will provide a more reliable supply of safe drinking water to homes and businesses in Titahi Bay and will reduce the risk of emergency repairs and increase earthquake resilience.
What are we doing?
The new water main will follow a new route along Tangare Drive, rather than going all the way along Titahi Bay Road, as the current pipe does. This change in route will mean less disruption on the main access route to Titahi Bay.
The Stage 1 route has been discussed and agreed with Ngāti Toa and Porirua City Council.
All Updates
Our crews have completed the important stage of laying the new main pipe under the road at the intersection with Te Hiko Street.
Big shout out to the Wellington Pipelines and Traffic Management crews who have been working overnights since 4 June to get this section complete without further disrupting traffic during the day.
There’s still more work to do but we’re due to finish work under and alongside Titahi Bay Road in August.
Thanks for your patience as we complete this important work on the pipes to secure the vital supply of drinking water to Titahi Bay.
Working from both the north and the south, we have so far laid 760 metres of pipeline, out of a total of 880 metres for stage 1.
We’re close to completing work along Tangere Drive and are now approaching the milestone of crossing Titahi Bay Road, laying the new main pipe under the road at the intersection with Te Hiko Street.
From Tuesday 4 June for approximately three weeks crews will be working overnight on this section, to avoid disrupting traffic during the day.
This means from 7 pm to 5.30 am there will be stop/go traffic control and you should expect delays.
During the day the road will be open, with trench covers over the excavations. There will be speed restrictions and traffic management around the worksites.

Titahi Bay pipes
We’re making good progress on replacing the Titahi Bay water main, which will secure and future proof the delivery of safe drinking water for the entire Titahi Bay Peninsula. The works are progressing from two sites, one from Tangare drive and one from Titahi bay road and will ‘meet in the middle’. This approach allows for a much faster project to minimise the window of disruption to residents and local businesses. Work started in January and is making good progress from both ends.
Our contractors Wellington Pipelines are working hard to provide vehicle and pedestrian access, with alternate access for foot traffic and plans in place to allow wheelchair or stroller users safe transit.
