What are the best ways to stop wasting water?

I stumbled upon a GOOD graph on this topic entitled "Every drop counts" (http://awesome.good.is/transparency/web/1108/water-usage/flat.html). According to the graph a family of four needs about 3 gallons of water per day, whereas US families can use up to 400 gallons.

It is a fact that water is becoming an increasingly precious resource and that we cannot afford to waste it. The graph already provides some good tips on how to reduce the wastage, but I was wondering what other things can help save water, and by this I mean not only direct methods such as repairing your dripping faucet, but also indirect ones such as eating less meat as 1 kilogram of meat needs a lot more gallons of water to actually produce.

I am looking forward to your answers!

  • Aug 29 2011: I guess I would need a better definition of what wasting water really is.

    My definition wouldn't be someone taking excessively long showers, as that water that goes down the drain doesn't leave the planet. Yes it does have to make its way through a wastewater treatment plant but eventually either collect into rivers and lakes or evaporate and fall as rain.

    I would consider wasting water any act that leaves it in an unusable conditions. For example, industrial manufacturing that contaminates water in it's processes. Another waste would be ethanal, that not only uses food for fuel, but it takes a lot of water to create that food.

      Aug 29 2011: just a very brief side note: ethanol combustion results in water vapor.

      the remark about polluting the water is spot on though.
