SUSTAINING OUR SOCIETY
Hatch Associates Pty Ltd
Adelaide Desalination Project
Due to a prolonged drought, the South Australia capital city of Adelaide has
been operating under permanent water restrictions. South Australia Water
commissioned a 100-gigalitre-capacity desalination plant to supplement
the fresh water supply, take pressure off the existing rain water catchment
system, and allow water levels to regenerate. Hatch SMEC JV was established
to support the Adelaide Aqua consortia—ACCIONA Agua, United Utilities,
McConnell Dowell, and Abigroup Contractors—in its bid to design, build,
operate, and maintain the AU$1.4 billion plant.
the allocated schedule. The material take-offs modeled in excess of 300 pieces
of equipment and 550 major piping process lines. The estimating process took
40 percent less time than anticipated.
The integrated team employed Bentley’s 3D modeling applications to achieve
an optimal and highly accurate plant layout and material take-off as well as
visualize the plant impact to the environment and local communities. The team
deployed the latest front-end engineering and design applications to deliver a
design, technical, and commercial cost estimate in 12 weeks. Using Plant Wise,
the team generated a 3D model of the reverse osmosis process building, intake
pump station, outfall energy recovery shaft, and other utility buildings within
To counter the impacts of the energy-intensive reverse osmosis process,
energy recovery devices were included in the process building and outfall
shaft, and solar energy panels will be installed on the process building roof.
