The Gold Coast Waterways Authority’s (GCWA) Coomera Dredged Sediment Management Facility (the Facility) is complete and ready to receive dredged material.

This is a $9.7 million investment by GCWA and City of Gold Coast in an environmentally sound and cost-effective long-term solution for handling dredged material from the Coomera River and its tributaries.

Dredging of the lower section from Sanctuary Cove to the Broadwater has commenced and the upper section (from Sanctuary Cove to the Gold Coast Marine Industry Precinct) is scheduled to begin by the end of April 2019. Completion is scheduled for September 2019.

As you would understand, dredging is necessary to reinstate the navigation channels of the Coomera River to design depth and width to provide marine access for businesses, residents and tourists to the Gold Coast Marine Industry Precinct, commercial harbours (such as Sanctuary Cove and Hope Harbour), residential estates (such as Coomera Waters, Coomera Quays and Riverlinks) and other tributaries and waterways. Dredging also improves water flow for flood mitigation.

GCWA will retain ownership of the Facility which is the first of its kind on the Gold Coast. It will also be made available for use by other organisations responsible for dredging the Coomera River and its tributaries including the City of Gold Coast, businesses within the Marine Industry Precinct, Sanctuary Cove, Hope Island and/or private residents.

Thank you for your patience during construction of the Facility and your continued understanding and support during dredging activities.
