The key to saving water can sometimes be...attitude!
Have a look at this great "Treehugger" article! "Singapore's water is not for sale! But you can Rent it!" Of course, we are all pretty much 'renting' water as we generally use it and then dispose of it. But thinking of water as not 'ours' to own is an interesting mindset to perhaps make us better stewards of this precious resource! When we remember that water isn't 'new' every time it runs through our faucets, it perhaps motivates us to keep it as clean as possible for the next time we need a 'rental'!
