A project focused on maintaining a reliable and healthy water supply for Invercargill has been named a finalist in national awards recognising outstanding public works projects across New Zealand.

The Branxholme Pipeline Upgrade was one of Invercargill City Council’s major infrastructure investments in the last decade.

The project saw almost 11km of aged pipeline between the Ōreti River and the water tower in Gala St replaced with a modern, resilient new pipeline – which is now fully operational.

The project has been selected as a finalist in the Excellence in Water Projects category – part of the the IPWEA Aotearoa New Zealand Public Works Excellence Awards.

The annual awards, run by the Institute of Public Works Engineering Australia, recognise innovation, sustainability, and asset management.

Invercargill City Council Chief Executive Michael Day said the accolade was well-deserved recognition for the Branxholme project.

“Water is a critical lifeline and essential to everything we do – our health, our homes, our economy, and our environment. The Branxholme Pipeline Upgrade was about making sure future generations of Invercargill and Bluff residents can rely on high-quality drinking water every day,” he said.

The new pipeline has an expected lifespan of more than 100 years, ensuring long-term reliability for the city’s water network.

Day said the project involved complex construction across urban areas, waterways, reserves and major transport routes, while maintaining water supply and minimising disruption to residents and businesses.

“Delivering a project of this scale while keeping the city moving takes careful planning, strong partnerships, and clear communication with the community,” Day said.

“Being recognised for the mahi undertaken is not only testament to the strength of the project itself, but to the collaborative effort that was poured into it along the way.”

Council appreciated the patience and support the project received from the community, Day said.
