Nihotupu 1 watermain upgrade

Project overview

The original Nihotupu 1 watermain was laid around 1905 from cast-iron pipe. Water is pumped from the Titirangi Reservoirs to the Nihotupu Reservoir and supplies approximately 18,000 elevated customers in Laingholm and Titirangi.

Due to the age and condition of the existing Nihotupu 1 watermain it needs to be replaced.

The overall construction timeframe for these works are from late May until late 2025. The majority of these works are in the Titirangi area.

Please refer to the overall site map to show the extent of the entire project.

First section of works on Atkinson Road and Kaurilands Road Titirangi

Our contractor for the project March Cato will start works from late-May 2025 until October 2025.

From late May our crew will start construction of the Bulk Supply Point (BSP). We will only work on the BSP to begin with (area on the map below shown in orange).

From late June/early July 2025 our crew will commence works on the watermains (area shown on the map below in blue).

Please refer to the map below for the work area.

How will this affect you?

• Working hours will be from 7am to 6.30pm, Monday to Friday and 7am to 4pm on Saturday including some Statutory Holidays.

• Traffic management including a partial lane closure during the watermain/BSP construction for the safety of the public and our workers. Please follow the direction of site personnel and all site signage to keep everyone safe. Please keep an eye out closer to the time for regular updates via our website, email, social media and letters.

• Some street parking will need to be temporarily removed near the work site to allow traffic management to be setup as part of the approved traffic management plan.

• Construction works will generate some noise and vibration; however, levels will be kept to a minimum and in accordance with Auckland Council and consent requirements.

• Please note that water supply to properties will not be affected during these works.
