Western Australia to receive first full-scale groundwater replenishment plant
Western Australia's Water Corporation has awarded CH2M HILL, as part of a joint venture with Thiess, a contract to design, construct and commission a full-scale advanced water replenishment plant -- the first of its kind -- in the city of Perth.
DENVER, CO, Aug. 8, 2014 -- Western Australia's Water Corporation has awarded CH2M HILL, as part of a joint venture with Thiess, a contract to design, construct and commission a full-scale advanced water replenishment plant (AWRP) in the city of Perth. The plant is the first wastewater recycling project of its kind in Australia and is a major step in progressing the Water Corporation's strategy for climate resiliency.
Construction on the first stage of the plant will begin later this month. The plant, which will inject highly-treated wastewater into Perth's underground aquifers, will have an initial capacity of 14 billion liters -- double the project's original capacity, with an option to expand to 28 billion liters in the future.
"With Australia's dry climate, groundwater replenishment provides a secure, rainfall-independent water source and will be an integral part of northern Perth's future water security," said Chris Morris, CH2M HILL Australia and New Zealand geography manager.
The Water Corporation undertook a complex groundwater replenishment trial (GRT) from 2010 to 2012 at the Beenyup wastewater treatment plant site to assess the technical and social feasibility of constructing such an advanced wastewater recycling plant for producing water that is suitable for replenishing groundwater.
The trial -- which involved treating approximately 3.5 billion liters of treated effluent from Beenyup using ultrafiltration, reverse osmosis (RO) and ultraviolet (UV) disinfection, as well as storing the water in an underground aquifer where it can be further filtered by natural processes -- was successful.
The new AWRP will be built on the same site as the trial, in Craigie. Construction of the project is expected to be in commission by October 2016. When commissioned, the plant will help Perth meet its future drinking water needs through 2060. For more information, visit http://www.watercorporation.com.au/gwr.
