How to Read Your Water Meter

Every Tampa Water Department customer has one or more water meters that measure the amount of water passing through in cubic feet units. One cubic foot of water equals 7.48 gallons. The Tampa Water Department bills water in units of 100 cubic feet (ccf) or 748 gallons per billing unit.

Where to Look on the Meter

  • Locate the white numbers on the right side of the meter dial (black background). Each turn of a number in the black register indicates that one cubic foot of water has passed through the meter.
  • Locate the black numbers on the left side of the meter dial (white background). Each turn of a number in the white register indicates that 100 cubic feet of water has passed through the meter.
  • The meter dial is read like an automobile odometer, straight from left to right.

Determining Your Water Usage

Use the following steps to help read your meter.

  • Select a day to take an initial water meter reading. Write down the numbers you see on the meter dial that indicate the total amount of water that has passed through your water meter up to this point.  Example: 007640
  • After a period of time has passed (a day or a week, for example), read your meter again at approximately the same time of day. Example: 008330
  • Subtract the first ready from the second reading. This is your water usage for the period. Example: 008330 - 007640 = 690 , which indicates that 690 cubic feet of water has been used during the time period between the two readings. This is equal to 6.9 ccf (or billing units), which is approximately 5,161 gallons of water.
