Dunkirk Road wastewater upgrades – Stage 2

Project overview

Over the next 50 years, the population of Panmure and the surrounding suburbs are expected to grow by more than three times due to planned development. We’re upgrading the wastewater network to support this growth and reduce wastewater overflows into the Tāmaki River.

The project is being delivered in three stages:

Stage 1

In 2024, we finished installing a new wastewater pump station on the corner of Dunkirk Road and Tangaroa Street and a wastewater pipeline along Dunkirk Road from Tangaroa Street to Johnson Reserve.

Stage 2

To connect the Tangaroa Street pump station to the eastern interceptor, we’re installing 1.3kms of wastewater pipeline, along with a new access manhole to support future maintenance.

The pipeline will run along: Riverside Avenue, Tangaroa Street, Tripoli Road, Torino Street and Pilkington Road before it connects into the eastern interceptor on private property. It will be installed using a combination of open trenching and trenchless construction methods.

We’re currently working through our final stage of planning to confirm the construction start date, laydown area and our traffic management plans. We will contact the community with more information once these details are confirmed.

Stage 3

In the future, we will replace approximately 500m of the existing wastewater pipeline on Dunkirk Road, south of Johnson Reserve, with a larger pipe to increase the networks capacity.
