You can save money on your water bill by repairing leaks and using water wisely. To check to see if you have a leak, turn off the water inside and outside of your home and look at your water meter. If any of the dials on your meter are moving, you could have a household leak.
The most common culprit for indoor leaks is the toilet. To find out if your toilet leaks, listen for the sound of running water. You can also place a few drops of food coloring in the tank. Don't flush the toilet. If the coloring is seen in the bowl, the toilet is leaking. Other indications of household leaks are dripping faucets and unusual wet spots in the house or yard. A leak of 30 drops a minute wastes 84 gallons of water a month.
Outside the house, water thoroughly but less frequently and only in the cool times of day. Turn off your automatic sprinklers when it rains. Water your lawn only when it needs it; if a screwdriver inserted into the soil goes in seven inches easily, the lawn doesn't need water. Don't let the hose run while washing your car; use a bucket instead with a quick hose rinse at the end. Use a broom instead of a hose to clean driveways and sidewalks.
Inside the house, run only full loads in your washing machine and dishwasher. Refrain from using your toilet as a wastebasket. Turn the water off while brushing your teeth and shaving. While waiting for hot water to come down the pipes, capture the cold water in a watering can to use later on your plants. Shorten your showers, and install a low-flow showerhead.
