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.

What is happening now?

From the 15th September - November 2025 our contractors will be conducting geotechnical investigations and various other topographical surveys. These early-stage surveys are essential to inform the design of the new water infrastructure and ensure it is tailored to the local environment.

During this time, you may notice temporary traffic management changes to various roads along the proposed pipeline route including:

• Stop/go systems in place

• Reduced lane widths

• Reduce off-street parking

• Reduced speed limits

• Pedestrian detours/reduced footpath width

• Bus stops along the proposed route. Please refer to the Auckland Transport website or app and plan ahead.

We ask that you please follow the direction of traffic management staff and traffic signage to keep everyone safe.
