Adelaide Desalination Plant
Securing South Australia’s current and future water needs.
Water is a vital part of every economy, community and environment around the world. Water security means having an affordable and acceptable quantity and quality of water for people, communities, industry and the environment, now and into the future.
The sea is an important source of water for South Australia and has 2 seawater desalination plants. Built in 2012, the desalination plant at Lonsdale is the largest of these with a capacity of 100 gigalitres per year. Importantly, it is Adelaide’s only source of drinking water that comes from a source that doesn’t rely on climate.
With our extensive experience in complex engineering and marine environments, The APP Group was appointed as an Independent Verifier for the construction of the Adelaide Desalination Plant. The design included two identical 50GL process plants, with two undersea tunnels for intake and outfall streams. The complex design also included landside shafts, interconnecting tunnels, an underground pump station, sub-marine tunnel connections, sea-floor risers and a marine intake structure and outfall diffusers.
Our team’s expertise in desalination, tunnels created by Tunnel Boring Machines, marine works and more to deliver verification that the design and construction had met all the requirements of the contract. The work included checking quality, project and design management, procurement, construction, testing, commissioning, reliability, operations, maintenance and Health Safety and Environment management and compliance.
