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 improve reliability for the future.

Most construction activity has been focused in the Titirangi area, with additional works in Glen Eden.

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

Update on current works in the area

Atkinson Road, Titirangi

Our watermain works on Atkinson Road are now nearing completion, and we’re also building an additional pump station as part of the Nihotupu 1 project. This will help strengthen the local water network and improve reliability.

• We expect to finish works on Atkinson Road by Wednesday 5 February 2026 including reinstating the road and surrounding area.

• Our goal is to have road reinstatement completed before school returns in February 2026, where possible.

Rosier Road, Solar Road, and Pisces Road (Glen Eden)

Watermain works are complete and connection works are underway. These are scheduled to be finished by early February 2026.

Kaurilands Road, Titirangi

These works are complete. Please note there are some minor works for approximately two days in the footpath outside 58 Kaurilands Road in January 2026.

Daffodil Street and Konini Road, Titirangi

Our watermain works on these streets are now complete.

Scenic Drive and Huia Road, Titirangi

Watermain works are now complete. Please note we will need to carry out connections early in the new year and the final reinstatement of the trench on Huia Road.

Upcoming works in Glen Eden – Withers Road, Kashmir Road, and Nandana Drive

While working in the area we have also identified additional sections of the local water network in Glen Eden that require upgrading. These areas include Withers Road, Kashmir Road, and Nandana Drive.

By laying this additional watermain now, we can complete the work more efficiently and avoid the need to return at a later date.

• These works are expected to begin in February 2026

• The work is expected to take approximately four months
