Waikōwhai water pump station and watermains

The latest

We have finished laying the watermain as you can see on the overall site map below.

We will be returning to the completed works areas (where we have installed the watermain) from 2-13 December to carry out  pressure testing, disinfection testing and small jobs. The good news about these works is that they will involve less traffic management and disruption. By 13 December, we will have removed all our traffic management from the roads in time for the Christmas break.

March to June works

We will return after the summer period to complete the pipeline connections into the networks. This work will 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. This project will enable 4,000 dwellings that are proposed by Kainga Ora, plus 170 infill dwellings within the Waikōwhai/Mt Roskill area. Please refer to the overall site works map showing upcoming sections of work, work in progress and completed sections.

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
