This project for the Rottnest Island Authority required the conversion of an existing aerobic digester into a Membrane Bioreactor (MBR) plant. GO's contract was for the design and construction of earthworks, process building including a control room, biological reactor and aeration systems, ultra-filtration membrane filters, chemical dosing and UV disinfection systems, pumping systems, electrical and control systems. The site is on an island off the coast of Perth, so construction required meticulous planning for the transport of equipment and the management of construction resources. The client subsequently awarded GO contracts for other work on the island unrelated to the treatment plant.
