What's in a UNIT? Water charges are based on increments of 100 cubic feet of water delivered, or what we call a billing unit. One unit equals 748 gallons. When the meter reader record the numbers on your meter, he or she disregards the number in black, recording only the numbers in white (multiples of 100). In the example above, the read shows on this customer’s water bill should be 368.
