Coastal Carrier System Upgrade

Gosford City Council is investing $30 million in the upgrade of the major wastewater transport system which services customers in Forresters Beach, Wamberal, Terrigal, North Avoca, Avoca and Kincumber.

The upgrade will improve the performance and capacity of the Coastal Carrier System (CCS) - which is over 30 years old - protecting the community and environment against wastewater overflows and meeting future demands in these popular areas.

The upgrade involves:

  • Building 6.5km of wastewater pipelines at North Avoca, Avoca and Kincumber;
  • Refurbishment of the major wastewater pump stations at North Avoca and Kincumber;
  • Upgrades to two minor pump stations in Avoca; and
  • Other various associated works including valve replacements and improvements to current odour control systems. 

Council has engaged NSW Public Works to assist in the delivery of the project.

Project status

Council has significantly progressed major aspects of the project. Approximately $9 million of newly laid pipeline stretching almost 4.5km through North Avoca and Avoca has been completed. In addition, the installation of the new transformers and associated works to the Avoca sewer pump station has been undertaken and the construction of a new rising main at Kincumber completed.

Further works have now commenced on the Avoca sewer pump station in Ficus Avenue and will be followed by valve replacement works on the North Avoca side of the lagoon.
