SUEZ supports Perth in efforts to reuse wastewater
Perth, Western Australia, has faced the reality of dwindling rain for more than a decade, which has had a negative impact on water dams and groundwater supplies.
To meet this growing challenge, Water Corporation, the principal supplier of water in Western Australia, invested in climate independent water sources, including a wastewater recycling process known as groundwater replenishment.
Able to contribute significantly to recharging groundwater, Water Corporation already operates an Advanced Water Recycling Plant with the capacity to recharge up to 14 million m³ of water per year. But the firm has also awarded SUEZ and its partner, Clough, a contract to build a new Advanced Water Recycling Plant located in Craigie, a northern suburb of Perth, capable of recharging an additional 14 million m³ of water per year, to bring the company’s entire total to 28 million m³ of water per year.
The use of advanced water treatment technologies such as ultrafiltration, reverse osmosis, and ultraviolet (UV) 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 around half of Perth’s drinking water supplies.
The 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 begin this month, and the plant will be commissioned in 2019.
“The southwest 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,” The Western Australian Governments Water Minister, Dave Kelly, said. “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.”
“SUEZ has been working with Water Corporation for several years in delivering quality drinking water to two million residents in Perth,” Marie-Ange Debon, Deputy CEO in charge of the International Division of the SUEZ Group, said. “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 division.”
