Groundwater replenishment works to create local jobs

24 October 2017

WA Government: Water Minister Dave Kelly today announced about 170 jobs would be created through stage two of the Groundwater Replenishment Scheme in Craigie, after the Advanced Water Recycling Plant contract was awarded. 

The Advanced Water Recycling Plant forms part of the wider $262 million expansion project which also includes a 13 kilometre recharge pipeline extending to the north-east of the plant, and two recharge sites in Wanneroo and Neerabup.

Construction is expected to begin this month and take about two years to complete.

Groundwater replenishment is the process where secondary treated wastewater undergoes advanced treatment to produce recycled water.  This water, which is now of drinking quality, is then recharged into an aquifer.  The water will remain in the aquifer for decades before it is drawn out at another location, treated at a water treatment plant and added to the water supply scheme. 

The contract was awarded to a joint venture between Suez Water & Treatment Solutions and Perth-based company Clough.

The joint venture - known as Clough-Suez Water Partners - will construct the Advanced Water Recycling Plant, which forms an integral part of the Water Corporation's expansion of the Groundwater Replenishment Scheme.  The plant will have the capacity to recharge up to 14 billion litres of extra water each year to groundwater supplies.

Stage one of the Groundwater Replenishment Scheme in Craigie is now complete and water recharge from the first plant is underway. This plant has the capacity to recharge up to 14 billion litres of water each year.  For more information, visit

Comments attributed to Water Minister Dave Kelly:

"I am pleased the Water Corporation is using the skills and expertise of Western Australians as part of this important project.

"Through this contract about 170 local workers will be employed, with 90 per cent of work to be sub-contracted or supplied by Western Australian businesses.

"The south-west of our State continues to be impacted by climate change, and groundwater replenishment is a key project in the Water Corporation's plans to secure water supplies in response to the drying climate.

"When the expansion is complete, the Groundwater Replenishment Scheme in Craigie will have the capacity to recharge up to 28 billion litres of water each year - enough to supply up to 100,000 Perth households."
