Charleston Dam Water Supply Infrastructure, Rural Queensland
North Marine is contracted to install Charleston Dam water supply infrastructure for the tender “Water Infrastructure Works – Installation Phase”, by Etheridge Shire Council, rural QLD.
Client: Etheridge Shire Council, Queensland
Scope of Work
Charleston Dam provides water to the townships of Forsayth and Georgetown in Queensland. The dam is located approximately 400km southwest of Cairns (1,800km north-west of Brisbane).
North Marine crew and commercial divers install water intake pipes, an electrical pump, four mooring systems and two pontoons to house the raw-water intake infrastructure, for the Charleston Dam.
Additionally, water pipes are poly welded and groundcover pipe/electrical cable areas are trenched and filled over (approx 100meters) from the reservoir to the dam.
North Marine was the primary contractor for this Tender, using sub-contractors for electrical and building/groundworks.
North Marine’s commercial diving division managed all aspects of the infrastructure installation. Furthermore, they designed, fabricated and installed the pontoon mooring systems – comprised of mooring blocks, chains, and cable, per naval architect drawings.
North Marine utilised workboat ‘Tin Duck’ and landing barge ‘Reef Safari’ on the Charleston Dam water infrastructure project.
- Design, fabrication and installation of mooring systems for the pontoons – 1 x Main Pontoon, 1 x Pump Pontoon
- Installation of pontoons – 1 x Main Pontoon, 1 x Pump Pontoon

Environmental management, including erosion, sediment control and operating within the ‘Environmental and Cultural Heritage Protection’ requirements, was critical.

About the Charleston Dam, in Queensland Australia
The Etheridge Shire Council constructed the Charleston Dam to provide town water supply to the townships of Forsayth and Georgetown.
It is located on the Delaney River in the remote Savannah Gulf Region of Queensland, Australia.
The area is considered an important cultural heritage site, and the dam has an Indigenous Land Use Agreement (ILUA) in place.
The planning process for the dam’s development has taken place in communication with the Traditional Owners of the land – the Ewamian People.
In addition to town water, the dam is used recreationally by locals.
