Northern Corridor Improvements Project – Rosedale Wastewater Treatment Plant

Northern Corridor Improvements Project at The Rosedale Wastewater Treatment Plant, Auckland, New Zealand.

Head Contractor: Abergeldie Harker
Asset Owner: Watercare NZ
Project Scope: An upgrade for Auckland’s Rosedale Waste Water Treatment Plant. Global Pipe supplied HOBAS CC-GRP Jacking Pipe to this project, with pipe specifications ranging from OD1280 PN1 SN32,000 Jacking Pipe and OD1499 SN32,000 HOBAS Jacking Pipe, for a total project pipeline of 1.1km. This project was supplied directly to the tunnelling contractor Abergeldie Harker. All pipe was delivered successfully without any disruptions to the construction schedule.

Project Background: The Auckland Northern Corridor project (also known as the Northern Corridor Improvements (NCI) project) is a major road and infrastructure project connecting the North Shore to the Western Ring Route which directly impacts the Rosedale Wastewater Treatment Plant.

The Rosedale Wastewater Treatment Plant is the second largest treatment works in the Auckland region and is among the largest in New Zealand, providing primary, secondary and advanced treatment of effluent for a population of approximately 185,000 people.

Project Planning:
 Global Pipe worked with the contractor Abergeldie Harker to assess the project requirements and create a seamless transition from planning and specification, to construction and project delivery. Global Pipe’s expert team studied the feasibility of the project to determine the use of HOBAS CC-GRP Jacking Pipe. After reviewing the project’s specifications, Global Pipe found a solution targeted to the project and then detailed the logistical solutions which would ensure the success of the project.
