INNOVATION IN WATER AND WASTEWATER TREATMENT PLANTS
New Main Brine Intake Station at Dead Sea
The Arab Potash Company produces potash by processing carnallite crystals
extracted from Dead Sea brine. Due to receding sea levels, a new intake
pumping station was required for operations at Safi, Jordan. Challenges
included selecting materials to withstand the corrosive brine, designing for
a location with poor geotechnical conditions, reducing power demands of
hydraulic pumps, and testing a possible 400 structural load combinations.
Dar Al-Handasah met these design challenges with the help of MicroStation
and PlantSpace, which allowed the team to coordinate design by incorporating
all disciplines—mechanical, structural, geotechnical, and electrical—into a
single model. The model was then used to extract drawings, plans, sections,
and details for the contractor. These savings in design time led to cost savings
for the $180 million station.
Hatch Associates Pty Ltd
Adelaide Desalination Project
SA Water commissioned a 100-gigalitre-capacity desalination plant to
supplement the state capital’s fresh water supply. The AU$1.4 billion plant will
take pressure off the existing fresh water catchment system, allow water levels
to regenerate, and give Adelaide a reprieve from water restrictions. Hatch
SMEC JV was established to support the Adelaide Aqua consortia in its bid to
design, build, operate, and maintain the plant.
The team deployed front-end engineering and design applications from Bentley
to deliver a design, technical, and commercial cost estimate in 12 weeks. Using
Plant Wise, the team modeled in excess of 300 pieces of equipment and 550 major
piping process lines. The 3D model was also used to define the most efficient
plant layout. The estimating process took 40 percent less time than anticipated.
