DENVER — Western Australia’s Water Corporation 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), the first wastewater recycling project of its kind in Australia, located in the city of Perth, according to a press release.

The plant will inject highly treated wastewater into Perth’s unground aquifers, and will have an initial capacity of 14 billion liters, with an option of expanding to 28 billion liters in the future, stated the release.

The Water Corporation commenced a complex Groundwater Replenishment Trial (GRT) from 2010 to 2012, at the Beenyup wastewater treatment plant site to evaluate the technical and social feasibility of constructing an advanced wastewater recycling plant that produces water suitable for replenishing groundwater, continued the release.

The GRT treated around 3.5 billion liters of treated effluent from Beenyup using reverse osmosis, ultrafiltration and UV disinfection, and stored the water in an underground aquifer, noted the release.

“The success of the GRT demonstrated the effectiveness of using advanced technologies and innovative solutions to treat water so it is suitable to replenish groundwater supplies,” said CH2M HILL Australia and New Zealand Geography Manager, Chris Morris. “We are delighted to tackle this advanced, complex project with our JV partner and the Water Corporation, helping secure Western Australia’s safe, reliable water supply for years to come.”
