The meter is owned and maintained by the City of McKinney
It is generally located in a small box in the ground near the street or the edge of the property.
It registers in gallons all of the water used in your home or building, as well as outdoor water use.
Most have electronic reading devices that allow the meter reader to capture the reading remotely
Meters are read monthly
All meters are calibrated and tested in the factory before they are shipped.
The American Water Works Association allows an error rate of 1.5%.
The design of the water meter does not allow the City of McKinney to adjust the dials.
Much like an automobile or other mechanical device, the meter slows down with age and can eventually stop registering completely, but it cannot run faster than it was designed to run. The mechanical parts are not capable of "speeding up" or registering a significantly higher reading than actual.
How to Read Your Meter
The meter dial is like the odometer on your car. It reads your water consumption and is a cumulative total of the water that has run through that meter since it was installed. You can get the consumption for a period of time by comparing the beginning reading to the ending reading. As water flows through the meter, the red hand rotates as it measures usage by the gallon. One revolution is equal to 10 gallons. Referring to the picture to the right:
The first 0 on the right doesn't move.
The next two numbers with the black background represent tens and hundreds of gallons of water.
Since we only bill per 1,000 gallons, the meter reader only reads the four digits to the far left (106). This reading is subtracted from your meter's previous reading (by the billing software, not the meter reader) to calculate your consumption. The 740 gallons will carry over to the next month.
