Aerated showerhead cuts water use by 30 per cent

November 17, 2006 With man’s mismanagement of the environment now firmly on the global agenda thanks to the growing evidence of global warming, water conservation is now an issue for everyone. Water, like money, is a very finite resource and if we don’t stop splashing it against the wall, we’re going to have serious long terms problems – all of us – not just the poor nations of the world but the rich nations too. So it was good news this week when we found that Australia’s national research agency, the Commonwealth Scientific and Industrial Research Organisation (CSIRO), has found a way to use a third less water when you shower, without diminishing the experience in any way. CSIRO scientists have developed a simple ‘air shower’ device which, when retrofitted to existing showerheads, fills the water droplets with a tiny bubble of air. The result is the shower feels just as wet and just as strong as before, but now uses much less water. The device is expected to retail for less than AUD$20 and be installed by householders. CSIRO is now seeking a suitable commercial partner to manufacture and market the technology globally. The CSIRO invention uses venturi technology.
