Do you know how much water a family of four uses every day in the United States? Not 50 gallons, not 100 gallons, but 400 gallons! You could take up to 10 baths with that much water—but who would want to do that? Fortunately, there are many things we can do to save.
Shower Power!
Taking a shower uses much less water than filling up a bathtub. A shower only uses 10 to 25 gallons, while a bath takes up to 70 gallons! If you do take a bath, be sure to plug the drain right away and adjust the temperature as you fill the tub. To save even more water, keep your shower under five minutes long—try timing yourself with a clock next time you hop in!
Fix That Leak（渗漏）!
Fixing a toilet leak is a great way to reduce household water use and boost water conservation. If your toilet has a leak, you could be wasting about 200 gallons of water every day. That would be like flushing（冲）your toilet more than 50 times for no reason! Try this experiment: ask your parents to help you test for leaks by placing a drop of food coloring(色素) in the toilet tank. If the color shows up in the bowl without flushing, you have a leak!
