Water scarcity in Western Australia: SUEZ supports Perth in wastewater reuse
Water Corporation, the principal supplier of water in Western Australia, has chosen SUEZ and its partner Clough, to build the new Advanced Water Recycling Plant located in the northern suburbs of Perth. This contract involves construction of a new 14 million m3 per year Advanced Water Recycling Plant to contribute significantly to groundwater’s recharge.
The Perth region has been facing more than a decade of dwindling rain, which has impacted drinking
water dams and groundwater supplies. To meet this growing challenge, Water Corporation has invested
in climate independent water sources, including a wastewater recycling process known as groundwater
Water Corporation already operates an Advanced Water Recycling Plant with the capacity to recharge
up to 14 million m3 of water each year. SUEZ and its partner Clough were awarded the contract to build
another 14 million m3 per year plant, bringing the capacity of the entire scheme to 28 million m3 of water
The use of advanced water treatment technologies such as ultrafiltration, reverse osmosis and Ultra
Violet disinfection guarantees a very high level of treatment and the production of high-quality drinking
water. This drinking water is then used to recharge the aquifers, which provide about half of Perth’s
drinking water supplies. This project is part of Water Corporation’s long-term plans to provide reliable
and quality water sources to the residents of Perth. The construction phase will start in November 2017
for commissioning in 2019.
The Western Australian Government’s Water Minister, Dave Kelly turned the first sod as part of
construction on Tuesday, 17 October 2017. “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 million m3
of water each year - enough to supply up to 100,000 Perth households”, said Dave Kelly.
SUEZ has been working with Water Corporation for several years in delivering quality drinking water to two million residents in Perth. We are proud of this new contract which will help increase the region’s water sources and sustainably secure drinking water supply to its inhabitants. It is a strong example of innovation contributing to our strategy of the resource revolution.
