Westfield Southdown Pipeline

Vector Gas

April 2009


Length: 1.6km

Size: 350NB

This inner city pipeline was build to increase the flow due to the additional demand, from the Westfield Delivery Point to the Southdown Delivery Point next to the cogeneration plant.

This project incorporated two HHD railway crossing under the Main North Island Truck Line and the North Auckland Branch Line and also boring under Great South Road without traffic disruption. Work was also carried out at night to help minimize traffic congestion. Our scope included Cathodic Protection, Pipe Wrapping and Hydro-testing.
