One of the options we are considering as a future water source is groundwater replenishment using recycled water. Groundwater replenishment is a process where water from a wastewater treatment plant undergoes several further stages of advanced water treatment, and is then added to groundwater.
From January 2010 until the end of 2012, Water Corporation will run a trial to assess the treatment processes, test water quality and monitor any effects on the aquifer to ensure the safety of the public and the environment.
The Trial will be overseen by the Departments of Health, Water and Environment and Conservation. Independent institutions including the CSIRO, the University of Western Australia, Curtin University and other international experts will also assist in the Trial and conduct related research.
Based on this research and community feedback, when the Trial finishes in 2012 the Water Corporation will prepare an internal source options report on whether groundwater replenishment is a sustainable water source option. Ongoing testing and monitoring results will be shared with the community via this website during the Trial.
Latest news
Construction of the facilities required for the Groundwater Replenishment Trial are now well advanced and the investigation of this promising future major water supply option is on track to begin January 2010.
The advanced water treatment plant is sited adjacent to the Water Corporation's Beenyup Wastewater Treatment Plant. Installation of all treatment equipment is expected to be complete by mid June, and will be followed by commissioning and testing. Background monitoring of the groundwater has also begun.
The advanced water treatment plant to be used in the Trial is being constructed and commissioned by the W2W Alliance, an alliance of Black & Veatch, Theiss and SKM.
