The Northern Network Alliance

The Northern Pipeline Interconnector (NPI) – Stage 2 is a $468 million
investment to help secure water supply for the growing region.

NPI – Stage 2 is a vital piece of drought contingency infrastructure
that will have the capacity to transport a target volume of 65
megalitres (ML) per day of potable water between the Sunshine
Coast and Brisbane.

The operation of the pipeline was redesigned
to enable reverse-flow to be achieved to provide security of supply
to the Sunshine Coast. This expanded the project works over 100
kilometres, from North Pine to Noosa Water Treatment Plant, and
included critical tie-ins to existing operating infrastructure.

CGS were hired by McConnell Dowell to provide survey for all aspects of the project.
