McConnell Dowell has been contracted to deliver design and microtunnelling services on a New Zealand outfall pipeline.
New Zealand utility Watercare has contracted McConnell Dowell to deploy Herrenknecht’s Direct Pipe® microtunnelling technology after successfully breaking what it says was the record for the longest Direct Pipe drive in Army Bay, New Zealand last year.
Under the design and construction contract for the Snells Algies Outfall Pipeline, the company will install approximately 4.3 km of 630 mm diameter pipeline, microtunnel 2.2 km of pipe using Direct Pipe and complete a 230 m marine dig and lay section.
“McConnell Dowell has a strong track record of delivering award-winning marine and tunnelling projects specifically ocean outfalls in New Zealand, which have greatly contributed to improving water quality in our harbours,” said McConnell Dowell Managing Director for New Zealand and the Pacific Islands Fraser Wyllie.
“We look forward to doing this once again at Snells Algies, applying our expertise in Direct Pipe methodology to improve water quality in the Mahurangi Harbour and delivering an upgraded wastewater system for this fast-growing region.”
Design will commence later this month, while works will begin later in 2019.
The project is scheduled for completion in 2021.
