Design direction and assistance commissioned by McConnell Dowell Constructors for the design the sand transfer infrastructure project for Adelaide’s Living Beaches Project. The project includes two sections of underground pipeline to pump sand south to restore eroded areas.

Sand recovered from two source beaches using mobile equipment will be slurried using a mobile sand collection unit and pumped to a range of outlets located in eroding areas. The 300mm diameter pipeline includes five underground pump stations. Water for the sand collection unit is supplied from two water pump stations attached to existing structures. The system can transfer sand with a mean diameter up to 1.00mm and includes a sediment analyser to control the operation; the control system will automatically vary the pumped slurry density to maximise the throughput for the sediment being pumped.
