Groundwater Replenishment

One of the options we are considering as a future water source option is groundwater replenishment.

Groundwater replenishment is a process where water from a wastewater treatment plant is treated to the highest standard through an advanced treatment process that includes reverse osmosis (desalination), then added to groundwater.

From the end of 2009 until 2012, Water Corporation will run a trial to confirm the treatment processes and monitor water quality and 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 their own 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.
