Branxholme Pipeline Upgrade hits major milestone

Invercargill’s pipeline upgrade is one step closer to completion following the successful connection and testing of a key link in the city’s new water main system.

The Invercargill City Council’s Branxholme Pipeline Upgrade will replace approximately 10km of the city’s outdated pipeline network, between the Branxholme Water Treatment Plant on the outskirts of Invercargill, to the water tower on Gala St, to deliver clean, safe water for the community.

Engineers on the Branxholme Pipeline project carried out pressure testing on the new connection between McIvor Road and the Waikiwi Reservoir in late April. The completion of this section signifies the northern section of the pipeline is nearing functionality.

“This section of pipeline has now successfully passed pressure testing and careful checking for integrity. These are critical steps in ensuring the pipeline’s readiness as we move to the next parts of this project,” Invercargill City Council Programme Director Lee Butcher said.

The connection of the McIvor Road section of the pipeline signifies more than 60% of the work of this upgrade is now complete.

“The next phase happening very soon will be to connect the pipeline into the Waikiwi Reservoir, leading up to achieving completion of the pipeline stretch from Pomona Road to the reservoir by the end of May,” Butcher said.

Residents around Gladstone Terrace, Russel Street, and Pomona Road West will notice ongoing works throughout May.

“The work on Russel Street involves the installation of new 125mm water supply lines to connect individual properties directly to the main water supply, followed by the installation of new footpaths, and kerb and channel improvements later in the month.

“This work has been scheduled at the same time as the Branxholme Pipeline works on Russel Street to reduce disruption for residents and improve the efficiency of the project.”

Invercargill City Council Group Manager – Infrastructure Erin Moogan said the project team had considered ways to minimise disruption at every stage of the work.

“A project of this scale is bound to impact residents at some stage; however, by carrying out work in stages and in conjunction with existing roadworks, we have been able to lessen disruptions significantly,” Moogan said.

About the Branxholme Pipeline Project

The Branxholme Pipeline Project is a significant infrastructure initiative by the Invercargill City Council to update the city’s water supply system to meet modern standards. The new 10km pipeline replaces infrastructure originally installed in 1958 with a durable and reliable infrastructure asset delivering a clean and safe water supply. The upgraded pipeline will stretch from the Ōreti River at the Branxholme Water Treatment Plant to the Water Tower on Gala Street, bolstering water supply to Invercargill and Bluff.
