How to Read Your Water Meter

See the photo, below, of an example meter. Your meter may look a bit different, but the method of reading it will be the same.

Water

To read your meter:

  • One (1) cubic foot of water equals 7.48 gallons

  • When reading your meter, ignore the first four (4) numbers on the right side of the meter, as they are not used for billing purposes. Billing is done in units of 100 cubic feet. Thus, if your bill indicates usage of "8" units, this equates to 800 cubic feet.

  • Your meter will typically have a "leak detector" - a small triangle or "gear" that spins when even the smallest amount of water passes through the meter. If you have turned off all water but still see this leak detector spinning, you should check your home for leaks. The most common culprit is a leaking toilet.

  • To check your average water consumption, simply get an initial read and then an ending read. For example, on Monday you check your meter and it reads "84" (remember - don't count the first four numbers on the right). Next Monday, you check your meter and it reads "87."

  • To calculate your water usage:
    Ending Read - Beginning Read X 100 = Cubic Feet Used
    Cubic Feet Used X 7.48 = Gallons Used
    Gallons Used ÷ number of days between reads = gallons per day

    Example:
    87 - 84 X 100 = 300 cubic feet
    300 cubic feet X 7.48 = 2244 gallons
    2244 gallons ÷ 7 days = 320 gallons per day (gpd)
    NOTE: This same calculation can be used to determine average water use from your water bill.
