Adelaide Desalination Plant

Project details: 

Independent Verifier for Adelaide Desalination Project

Adelaide's Desalination Plant was built to provide secure sources of water to Adelaide, regardless of climactic conditions.  APP was the Independent Verifier on the $1.8bn South Australian Project, located at Lonsdale, near Adelaide. The appointment was made jointly by SA Water and AdelaideAqua D&C Consortium, and APP was selected based on the verification knowledge and background that only APP can bring to a project.

The new plant reduces reliance on inflows to the reservoirs in the Mount Lofty Ranges and the Murray-Darling Basin catchments by delivering a supply of 100 gigalitres of potable water per year.

The project comprises two 50 gigalitre Reverse Osmosis plants and two underground tunnels for seawater intake and return to the sea.

As Independent Verifier, APP’s core service was to verify that the design and construction were carried out in accordance with the contract requirements. This was achieved through observing, monitoring, reviewing, auditing and verifying the quality assurance and project management systems and the design documentation, construction, materials and operations and maintenance procedures of the project.
