Scientists say that water shortages will be a serious world problem. So it's time for all of us to learn to save water!
What can we do to save water? Here are some ways.
Try to use less water in the bathroom.
Turn off the water when you brush your teeth. Keep your showers short because a shower uses 10 to 20 liters of water a minute. In this way, you'll save thousands of liters of water a year.
Check your water meter at home. First, turn off the taps, and read the meter. Then wait for 30 minutes and read it again. If the water meter moves, there may be something wrong with the toilet or water pipes. Repair them as soon as possible.
