The figure represents wastewater experts have treated, recycled, purified and recharged back into Perth’s groundwater supply as future drinking water.

Achieved over three years at Beenyup Wastewater Treatment Plant off Ocean Reef Road, it would fill more than 1556 Olympic-size swimming pools.

Water Minister Mia Davies said the trial plant had tested groundwater replenishment in local conditions and ensured it could meet health targets.

The first stage would recharge seven billion litres of water annually, expanding to 28 billion litres as population and needs grew.

‘In our drying climate, groundwater replenishment provides a secure, rainfall independent water source with potential to supply up to 20 per cent of Perth’s future drinking water needs by 2060,’ she said.
