Wikihow has one of the simplest step by step instructions on how to reduce the amount of water you use when you flush the toilet. Even a monkey could follow this one. It's as simple as grabbing a plastic bottle, such as a used water bottle, refilling it with water and placing in your toilet cistern. Simple. If you would like the pictorial instruction, here it is!

I have a theory that water filters help save water.  Maybe it's psychological on my part but when we had (yes had - it broke) a water filter, I reckon we were more careful with the water we poured out of it; we treated the water like it was more precious.  Now that the water filter has gone (soon to be replaced) I feel as though we're a little more careless with the water we use from the tap for drinking purposes.  Water from the tap comes out faster and dirtier and perhaps that's why we treat it with less respect than the water from a water filter.  Just a theory though!

Two things near and dear to my heart, saving water and Nintendo Wii!  Core77 have issued a water saving design competition where the winner can win a Nintendo Wii.  All you have to do is design a novel water saving device for the bathroom and submit it to the Core77 Water-saving designs for the bathroom competition.

How many times have you been our at a pub or night club only to wake up the next morning (somewhere) stinking of cigarette smoke?  Your hair and clothes smell like you're a two pack a day smoker. The fist thing I do the morning after is throw all my clothes in the wash then take a long shower making sure I wash my hair twice to remove the stench.

This may be drawing a long bow, but given careful consideration, might the recent ban on smoking in Victorian pubs, with other states soon to follow, help save water?  I know if my jeans are relatively stain free and not smelling like a pack of Malbro's the morning after, I'm more than happy to give them another ware.

Think of the thousands of ash trays that no longer have to be washed out at the end of the night by the bar staff down at your local.  Who know how much water banning smoking in pubs will save.

Brisbane physicist Dr Ian Edmonds has had a novel idea for transporting water from rain soaked North Queensland down to the drier regions of South East Queensland and NSW.  Dr Edmonds has suggested floating large volumes of fresh water down the Australian east coast in large plastic bladders.  With the natural current that flows from north to south down the East Coat of Australia, Edmonds suggests it would be cheaper and more environmentally friendly than desalination plants or pipelines.

I think we need more novel thinking like this to solve our water woes and to solve the global warming crisis we're facing.
