Waikōwhai water pump station and watermains
Upgrades are required to cater for development in the Waikōwhai/Mt Roskill area.
Duration
Pump station (March 2023 – March 2024) and watermain (early 2025)
Location
Mt Roskill
Status
Construction
The latest
We have finished laying the watermain and will return in early February to complete the pipeline connections into the networks. This work will take approximately four months and involve less traffic management than our watermain construction.
Project overview
We are undertaking upgrades to the water network to cater for current and future development along with population growth. The current water network cannot cater for any further growth in the Waikōwhai/Mt Roskill area. The project will enable growth and new development in the area.
The proposal
- Approximately 5,750 metres of watermains will be constructed, ranging in diameter from 300mm to 450mm. It is estimated the construction of the watermains will take approximately 18 months to complete
- One new bulk supply point
- A new booster pump station at 1374 Dominion Road (adjacent to the Akarana Golf Club) to replace the existing Hillsborough Pump Station
Connection and commissioning works
While the installation of the watermain is now complete, we still need to carry out the final connection and commissioning works for the Waikōwhai watermains project.
These works will begin in early – February 2026 and continue until approximately late June-2026 and will require significantly less traffic management that the earlier watermain construction phase.
The work will be completed in stages, beginning with the first section on Richardson Road (as shown on map below) from early February 2026.
