McConnell Dowell to complete new stormwater outfall project at Ports of Auckland

 

McConnell Dowell is pleased to announce the award of the Ports of Auckland Stormwater Outfall project by Auckland Council. The project to construct the last and most challenging section of the Stanley Street catchment network upgrade is required to mitigate future flooding risks.

The new outfall will increase the stormwater capacity and provide greater resilience to Auckland’s downtown infrastructure, particularly the Britomart Railway Station. The scope of works consists of a substantial inlet structure that will link to existing infrastructure and an outlet in the port area, via a 2.5m ID x 270m long deep siphon to a discharge point into the Waitemata Harbour, near Furguson Wharf. Due to the depth and ground conditions, installation of the pipes will be carried out using a “state-of-the-art" closed face tunnel boring machine.

 

This project is technical and will build on McConnell Dowell’s extensive track record in the construction of major marine outfall pipelines in New Zealand and trenchless capability.
