Hunter Water continued its commitment to extend the water grid between the Hunter and the Central Coast with the construction of Stage 4 of the Gosford to Wyong pipeline link. Stage 4 of the project increased Hunter Water's capacity to deliver water to Wyong from 25 megalitres (ML) to 33 ML per day.

The project involved construction of around 7 kilometres of pipelines through Boolaroo, Teralba, Fennell Bay and Rathmines.
