Wellington Water, on behalf of Porirua City Council (PCC), is upgrading the main drinking water supply to Tītahi Bay. The existing 225 mm AC main pipe, originally installed in 1963, was replaced with a 1.3 km 300 mm polyethylene (PE) water main following a new route from Elsdon Park and connecting into the existing network at Whanga Crescent.
This was Stage 1 of the staged project. We are soon to commence Stage 2 which will progress up the walkway to Puaha Street and Mataiwhetu Street, before crossing into Hukarito Valley and connecting into Whanga Crescent.
Why are we doing this work?
The pipe has a history of bursts because of its age, material and existing ground conditions, and is considered seismically vulnerable. The frequent bursts leave the Tītahi Bay community without drinking water during repair work, and repairs disturb the surrounding environment.
Benefits?
- A resilient and reliable water network supplying the community of Tītahi Bay.
- Restore operational integrity to the water network in Tītahi Bay.
- Reduced impact to Te Taiao (environment) from pipeline bursts and the subsequent maintenance activities.
What does the work involve?
It was planned that the pipe is to be replaced in two stages:
- Stage 1, was from Elsdon Park to the northern end of Tangare Drive, in the Tītahi Bay Road and Tangare Drive road corridors. This stage has now been completed.
- Stage 2, which is starting soon, is from the end of Stage 1 to Whanga Crescent.
When is the work happening?
Construction of Stage 2 is anticipated to be during the drier months of the year. Dates for this work are yet to be confirmed.
Stage 2
Shown below, Stage 2 will start from the end point of Stage 1, where it will progress up the walkway to Puaha Street and Mataiwhetu Street, before crossing into Hukarito Valley and connecting into Whanga Crescent.
This stage is due to commence soon. Detailed design included careful planning and consideration into the crossing of Hukarito Stream, and the potential impact on community members.
