Find monthly water meter readings on the water meter and on the utility or water bill. To determine monthly water usage by reading the meter, find the reading from the same day the previous month, and subtract the two numbers to obtain water usage for the month.
Water meters are typically installed near property lines or roads in cement boxes. To access the meter, remove the lid. A light may be needed to activate the display on a digital meter, while an analog meter has a needle that sweeps around one time as 10 gallons or cubic feet of water go through the meter. The total number on both types of meters shows usage, while digital meters also display the flow, or amount of water going through the meter per minute. Monthly water meter readings on utility bills typically show up in two numbers: the actual meter reading number and the water usage.
