THE State Government says 170 jobs will be created through stage two of the groundwater replenishment scheme at Craigie’s Beenyup plant.
It has awarded a construction contract to Suez Water & Treatment Solutions and Perth-based company Clough.
The joint venture will construct a water recycling plant, which forms part of the Water Corporation’s $262 million expansion project that also includes a 13km recharge pipeline extending to the northeast of the plant, and two recharge sites in Wanneroo and Neerabup.
The plant will have the capacity to recharge up to 14 billion litres of extra water each year to groundwater supplies.
Construction is expected to start this month and take about two years.
In groundwater replenishment secondary treated wastewater undergoes advanced treatment to produce recycled water. The drinking quality water is then recharged into an aquifer.
The water will remain in the aquifer for decades before it is drawn out at another location, treated and added to the water supply scheme.
Stage one of the groundwater replenishment scheme has been completed and water recharge from the first plant has started.
“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,” Water Minister Dave Kelly said.
The expansion will double the recharge capacity of the Craigie site from 14 billion litres.
