Watercare engaged McConnell Dowell and our design partner, McMillen Jacobs in March 2017 to install a new wastewater outfall, upgrade the existing pump station and build a new ultraviolet disinfection facility to increase the outfall capacity for its Army Bay Wastewater Treatment Plant at Shakespear Regional Park on the Whangaparāoa Peninsula. Shakespear Regional Park (SRP) is a pest-free conservation area, home to a variety of native wildlife including Kiwi, Little Blue Penguins and skinks, so choosing a construction methodology that minimised impacts on the area was important. Direct Pipe®, a methodology new to New Zealand, was ideal for this project as it enables small diameter pipelines to be installed over large distances more accurately than traditional trenchless tunnelling techniques. In delivering the project, McConnell Dowell achieved a world-record for the longest Direct Pipe® drive.
