Revelations about the use of WA's groundwater by bottled water companies, along with record low rainfall, have focused attention on the best way to manage a scarce resource.

“We send about 100 gigalitres [of stormwater] a year out to the ocean, some of that’s pretty important, it’s our rivers flowing, so we don’t want to get rid of all of that, but some of that is our harvestable resource, and it’s our treated wastewater, and we send over 120 gigalitres of that out to the ocean every year,” she said.

These are two good ideas with low cost implementation

The idea for the watering more often with less water could also be workable.

I still think Western Australians should be building many more desal plants to really begin negating the states reliance on a good winter for community and environmental watering needs.

A more consistent statewide watering regime will help with things as different as farmers maximising and predicting crop yields, to reducing the risks associated with fires after dry summers.
