New Zealand pipes in safe hands

All across New Zealand local councils and authorities are investing in upgrading and expanding the country’s pipe infrastructure.

With the ambitious goal to improve the lives of communities and the environments in which it works, Interflow is the all-in-one delivery partner helping the nation grow and safeguard its pipeline infrastructure.

The city of Nelson, in the Tasman Bay in New Zealand, recently required assistance with improving its wastewater service. Failure of the network risked impacting the Waimea inlet – the largest semi-enclosed estuary in the South Island.

Trenchless pipe rehabilitation has been in the company’s wheelhouse since the 90s when it adopted trenchless spiral-wound lining technologies.

Interflow’s engagement with customers has always involved a close relationship, enabling the company to tailor solutions to each specific project. Its expertise in trenchless technologies means these solutions minimise disruption and environmental impact.

As a result of this close engagement with the Nelson Regional Sewerage Business Unit, the decision was made to recommission a section of sewer that ran beneath the inlet. The section had been out of commission since 2007, but Interflow were able to install a new liner using Primus Line.

Not only was the section recommissioned, but the project involved a 1.1 km pull which was, at the time, Interflow’s longest.

The solution was fast, cost-effective and sustainable. Interflow’s national product manager Will Zillmann said that the under-water nature of the project meant that crews used specialised equipment and took extra care to ensure no discharge into the surrounding bay.

As a local delivery partner, Interflow will continue to work closely with New Zealand as the country proactively improves its water and wastewater infrastructure.
