SA Water awarded the design, build, maintain and operate contract of the Adelaide Desalination Plant to the Adelaide Aqua consortia involving McConnell Dowell. The project involved the design, construction and commissioning of a 100 GL per annum reverse osmosis desalination plant.

As the largest water infrastructure project completed in South Australia, it encompassed extensive work in all construction disciplines including bulk earthworks, civil structures, marine, tunnel and underground, mechanical, electrical and building works.

The construction team established industry leading approaches in protecting the local environment by developing a customised floating detention and sedimentation system to minimise the impact of construction works on the local marine ecology.

The plant has set benchmarks for energy savings and minimised the physical footprint of the plant. The innovative pre-treatment process has provided high levels of reliability, by using less energy and reducing chemical dosing requirements.

Following a successful construction handover, the Adelaide Aqua O&M team continue to exceed the expectations of the client by reducing operating costs, environmental impacts and energy use
