What are we doing?

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.

Update on works on Donovan Street, Blockhouse Bay

Our contractor for the project, March Cato, has begun installing a replacement watermain pipeline using the trenching method along Donovan Street on 27 December 2023. They started at the roundabout and continue until Boundary Road. These works will be carried out in five stages (please note, the stage five works is yet to be confirmed).  

We are happy to report that these works are progressing well, and we have now laid the new watermain from the Blockhouse Bay roundabout (roundabout with the intersection of Donovan Street, Kinross Street, Blockhouse Bay Road, and Heaphy Street) up to approximately 56 Donovan Street, Blockhouse Bay. 

Please refer to the map below showing the current traffic management setup (stage 2 works). This traffic management setup will be in place until 8 March 2024 from 26 Donovan Street (opposite Countdown) to the Donovan Street/Lewis Road intersection.

Traffic management will be in place in the form of one lane open travelling in a west bound direction and a detour will be in place around the works area for cars travelling in an east bound direction. Rathlin Street and Whitney Street will remain open. Please refer to the map below for the works area and traffic management in place.

Works on McCullough Avenue and Scout Avenue, Mt Roskill

You may be aware that our crew has been busy laying the watermain on McCullough Avenue, Mt Roskill. These works are progressing well, and our crew is currently at 78 McCullough Avenue. Over the next couple of weeks (before the Christmas break), our crew will continue to work up McCullough Avenue onto Scout Avenue, where we will construct the watermain up to the Scout Avenue/Mt Albert Road intersection. As we move up Scout Avenue, we will be reducing the number of road closures.

Our crew will finish work on 22 December, returning on 8 January 2024 to complete this section of works which we estimate will be done by late March 2024.

We will move to the below traffic management plan from around 15 December.

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.​
