In many operations, within the industrial, construction and commercial sectors, the use of water is often an accepted process cost.  There is scant attention paid to reducing such a significant service cost with fixing leaking taps often being the extent of energy saving in this area.

With water shortages reported recently in Australia, in many of the Mediterranean countries and in a string of other countries across the globe, we are increasingly becoming aware of the fragility of this planet's future and our place within it. We have huge quantities of water on the blue planet, yet only 2% of it fresh water.  We have a growing population, set to hit nine billion by 2042 - that's 2.7 billion more than now - so not an inconsiderable rise in numbers.  Not unreasonably, they will all want drinking water, bathing water, better food and a better quality of life - all of which demand more high quality water.
