Just 14 per cent of waste water was recycled in WA in 2011-12, of which 5.9 billion litres was used to irrigate public parks.
In a report released last week, the Water Corporation called for this rate to be increased to 30 per cent by 2030 to cope with a drying climate and to reduce reliance on groundwater supplies.
Joondalup Mayor Troy Pickard said the City had cut its groundwater use, which accounted for 98 per cent of water used, by 27 per cent in three years.
‘The City of Joondalup has been proactive in reducing the amount of water used for irrigation by implementing hydrozoning and ecozoning and improving water efficiency at City parks,’ he said.
The City has also installed pool covers, waterwise showerheads and tap-fittings and dual flush toilets to reduce water use at Craigie leisure centre.
