Devonport 2 Watermain Replacement Project

Project overview

The Devonport water supply zone serves approximately 12,300 people through over 5600 metered connections. This area includes the suburbs of Narrow Neck, Devonport, Stanley Point, and North Head. Currently, the area is serviced by two watermains called Devonport 1 and Devonport 2. Devonport 1 was renewed in 1997 but has reduced capacity, while Devonport 2, an asbestos cement watermain installed in 1960, is in poor condition and has now reached the end of its serviceable life.

Watercare plans to replace the Devonport 2 watermain with a new 4.5-kilometre pipeline. This upgrade will improve the resilience of the water network, reduce ongoing maintenance requirements and increase water supply capacity in the area.

Construction is currently scheduled to begin in early-2027 and is expected to be completed by late-2028. In preparation, our contractors, will be conducting geotechnical investigations and various other topographical surveys within roads, berms, and reserves along the proposed route – see map below.

These early-stage investigations involve the use of specialised equipment to study the soil composition and underground conditions. The data collected will help us ensure the new watermain is designed to suit the local terrain and built to last. During this phase, you may notice our staff using equipment such as drilling rigs, surveying tools, and ground scanning devices.

How will this work affect you?

Investigations will take place from mid September 2025 to November 2025 between 7am - 6pm Monday to Friday and occasional Saturdays if required. Should there be any changes you will be notified in advance.

• Investigations may generate some noise and vibration; however levels will be kept to a minimum and in accordance with Auckland Council requirements.

• Temporary fencing and road barriers may be setup around the investigation sites.

• All investigation sites will be fully reinstated upon completion of the works.

• We do not anticipate disruption of vehicle access to your property however, if there is a need to restrict access, we will notify you in advance.
