Huia 1 watermain upgrade

Watermain replacement to cater for population growth.

Start–finish: June 2019 - ongoing in stages
Location: Sections along White Swan Road and Golf Road

What’s happening now?

Till mid-March we will be replacing our large watermain along Titirangi Road. There will be road and lane closures during this time. Replacing the pipeline ensures we can continue to provide essential water services to Auckland and cater for the growing population. Please follow the detour signs and directions of traffic management staff on site. Thank you for your patience over this period.

Staging of traffic management (estimated dates):

Titirangi Road update

Our contractor, March Cato, is moving fast with the pipeline installation and is now approaching the intersection of Highland Avenue. Tomorrow evening (26 January), traffic management will be installed at the intersection. There will be one-lane with stop/go signals in place for work starting Thursday 27 January. Please see the attached traffic notice for more information.
 
We are still working on the chamber at Golf Road intersection which requires a full road closure from West Lynn Road to Highland Avenue. Where possible, road users are advised to take alternate routes where possible, such as Atkinson Road and Godley Road while we work at the intersection of Highland Avenue and Titirangi Road. We will notify road users via this channel when any changes are made to traffic management on Titirangi Road. We are hoping to open the road to one-way traffic as soon as possible once the chamber is complete – this will be around 14 February. We will then be trenching a smaller pipeline along Titirangi Road between Golf Road and Pleasant Road intersections.

Highland Road residents

We will only be going a short way into Highland Avenue intersection. Once we have completed a few pipelines into Highland Avenue from Titirangi Road, we will reinstate the road, then return once Titirangi Road is complete. We apologise for the disruption and will communicate with residents in advance once the timing for the rest of Highland Avenue is confirmed.

Frenz Drive residents

We will be starting at Frenz Drive in approximately two to three weeks’ time. Our contractors will communicate directly with residents about how the works will affect them.

White Swan Road (from Pascoe Street intersection to Hillsborough Road intersection)

We will soon be completing the pipeline installation on White Swan Road and are aiming to have the road reopened in the next few weeks (approximate date 17 December, weather permitting). Please note: The Blockhouse Bay section of the pipeline replacement which runs from Heaphy Street (near the roundabout) along Donovan and White Swan Road to Hillsborough Road intersection is still outstanding while we plan this complex section. We will provide you updates once the work has been planned.

Golf Road (at Gilliam Street intersection)

We are building a chamber and completing connections on White Swan Road to complete the pipeline installation. Golf Road will be one lane during the works, with traffic managed by signals or traffic lights for traffic both ways. Gilliam Street will be closed at the intersection for through traffic. The works have been delayed until late August or early September. We will update residents and those signed up for updates once a new start date has been scheduled. Click here to sign up for updates. The work will take approximately four months to complete. The connections were not able to be completed during the pipeline construction due to water restrictions that were in place at the time. Click here to see the traffic management plan.


Why are we doing this?

We are renewing the large-diameter watermain called Huia No.1 which has reached the end of its useful life. The watermain was built in the 1940s after World War II. To extend its life we rehabilitated the watermain in the 1980s but we now need to build a new pipe. Over the next few years, the 17km pipe is being built in sections across West and Central Auckland. We thank you for your patience and understanding while we undertake these essential works.

Mt Roskill

Bremner Avenue

We have completed pipeline installation from Winstone Street to Bremner Avenue. We will need to return to undertake works in John Moore Park for custodial protection of the new pipeline with access from Bremner Avenue. Residents will be advised of construction once it is confirmed.


Winstone Road

We are currently piping a section of the pipeline under a culvert in the road, and aim to complete it by the end of June. The rest of the pipeline has been installed. There will be some closures on Memorial Avenue for an additional line-valve that needs to be added later.


Mount Roskill Reserve

Connection and pipeline work needs to be completed in the Reserve. There will be some tree removal for construction. Click here for more information.


White Swan Road (between Pascoe Street and Hillsborough Road intersections)

We will soon be completing the pipeline installation on White Swan Road and are aiming to have the road reopened in the next few weeks (approximate date 17 December, weather permitting). Please note: The Blockhouse Bay section of the pipeline replacement which runs from Heaphy Street (near the roundabout) along Donovan and White Swan Road to Hillsborough Road intersection is still outstanding while we plan this complex section. We will provide you updates once the work has been planned.

Blockhouse Bay

Golf Road

We have completed pipeline installation along Golf Road and the road is now open to through traffic. We will need to return to complete localised connection work at the intersections of Titirangi Road, Gilliam Street, Astley Avenue and Portage Road.


Donovan Street and White Swan Road

We are currently looking at design methodology for this section. Residents, businesses and community members will be notified once we have confirmed the design and timing of the works.

Titirangi​

Titirangi Road from Golf Road to Highland Avenue

From mid-December 2021 till mid-March 2022 we will be replacing our large watermain along Titirangi Road. There will be road and lane closures during this time. Please detour along Godley Road to Stottholm Road or take an alternative route to avoid this disruption. Replacing the pipeline ensures we can continue to provide essential water services to Auckland and cater for the growing population. Please follow the detour signs and directions of traffic management staff on site. Thank you for your patience over this period. Click here to view the traffic notice.

General traffic management FAQs

Q: Why do we not have tidal flow (changing of traffic flows during the day and night)?
A: Tidal flow is a viable option where there are multiple lanes that can be changed i.e. Whangaparaoa Peninsula. Where there is only one lane through residential streets, tidal flow is not feasible. It is not safe for local residents as traffic flows change during the day and confusion around traffic direction could occur.

Q: Why don’t we use traffic lights or stop-go operations?
A: This is not feasible due to the length of the work sites. Traffic queues would become too long making it less efficient than one way traffic.

Q: How will we notify road users?
A: VMS digital sign boards are the most effective way to communicate with road users. In advance of the works we implemented VMS boards.​
