1. Automatic dishwashers use up to 15 gallons for every cycle, regardless of how many dishes are loaded, so get a run for money and load it to full capacity.
2. Turn off the tap when brushing your teeth.
3. Check every faucet in your home for leaks. Just a slow drip can waste 15 to 20 gallons per day. Repairing these problems can save 6,000 gallons a year or more.
4. Check your toilets for leaks by putting a few drops of food coloring in the tank, watch for a few minutes to see if the color shows up in the bowl. It is not uncommon to lose up to 100 gallons a day from one of these otherwise invisible toilet leaks. Fix it and you can save more than 30,000 gallons a year.
5. Use your water meter to detect leaks. Simply turn off all taps and water using appliances, then check the meter after 15 minutes. If the meter moved, you have a leak.
