There's several ways to conserve water in your home for example;
To check your toilets for leaks, put a little food coloring into the toilet tank. If, without flushing, the color begins to show up in the bowl within 30 minutes, you have a leak that ought to be repaired immediately.
Next, for those who love their long, hot showers (including me) you waste 5-10 gallons of water every unneeded minute. Just simply limit your showers to the time it takes to soap up,wash down, and rinse off. It saves lots of water(Especially if you think of it over a week period or even a month!) and time.
Next, Look into insulating your pipes, (if you haven't already), they help you get hot water faster(goes along with us hot shower people).
And Lastly, which is a simple one that everybody ought to know or at least do....TURN THE WATER OFF AFTER YOU FINISH PUTTING WATER ON YOUR TOOTHBRUSH!!!!! If you dont do this just imagine how much water you've wasted because you were brushing your teeth, then after that you need another glass to fill due to rinsing.
