If your home has a water meter:
Bills are based on your water usage during the winter quarter, as measured in cubic feet of water (listed on your bill as CCF).
That water meter reading most closely reflects the amount of water used inside the house and is not affected by activities such as watering your lawn, washing a car, or filling a swimming pool. A CCF is equal to about 750 gallons of water, which is enough water to run a dishwasher about 50 times.
