The water meter is generally in a concrete box marked "water" on the lid, located near the curb in front of your home or place of business. By reading your water meter, you can tell how much water you use, and you can check for leaks. If you turn off all the taps, and the meter is still turning, you'll know that you probably have a leak somewhere.
To remove the lid, insert a tool such as a large screwdriver into one of the holes and pry the lid off. Visually examine the area around the meter to make sure there are no harmful insects or other animals. The water meter measures in units of cubic feet. One cubic foot equals 7.48 gallons. Your water bill is based on the number of units of 100 cubic feet used during the billing period. The abbreviation for 100 cubic feet is ccf, with one ccf equal to 748 gallons of water. Let's say, for example, that you check your meter and it reads 21,500. This number represents the total number of cubic feet of water recorded since the meter was installed. If, when you check your water meter again, you've used 1,500 cubic feet of water, the water meter would then read 23,000 cubic feet (21,500 plus 1,500).
