Wise water ways: At home with water efficiency

Tap aerators and flow restrictors

Eva Matthews looks at the gadgets, habits and tools that can help you make the most of our precious H2O.

THE water account for 2013–14 from the Australian Bureau of Statistics reveals some useful facts about our water use at home. Household water consumption for the year totalled 1872 GL—equivalent to just under four Sydney Harbours. And the Sydney Harbour analogy is particularly relevant, as NSW was the highest-using of the states and territories by almost double that of the next-highest, partly because of its larger population. Per capita usage was highest in WA (361 kL) and NT (416 kL) per person per day; Victoria was the lowest at 175 kL and NSW, ACT, SA, Tasmania and Queensland were all in the range 200 to 220 kL.

In the same time period, this water use cost households around $5 billion, and prices are rising (up around 25% on the previous year in NSW and Vic). And then there’s the fact that, despite Australia’s average rainfall being well below the global average and likely to remain so, we are the greatest per capita consumers of water, not even including the water embodied in the production of the food and products we consume. These stats make it pretty obvious that we are not, as a nation, living sustainably or smartly enough when it comes to this precious natural resource.

So what can we do to improve this situation? Primarily, use less water and make the most of the water we have! There are also national and state/territory-based rebates and incentive schemes (such as showerhead swaps, rainwater tank and greywater system rebates, appliance upgrades, toilet replacement and leak fixing services) to help people become better water savers.
