The size of your water meter is shown on your bill. If you want to find out your water pressure, call the Engineering Records Department at 945-1530. The industry standard is cubic feet, even though most people have a much better understanding of gallons than they do of cubic feet. We currently have 60,000 meters with cubic foot registers. Changing them all to gallons at this point in time would be an expensive proposition.
Nothing lasts forever, and meters, like most things in life, tend to slow down with age.
Based on sample tests, we have determined that water meters are accurate for about 20 years. The accuracy of your new water meter is certified by the meter manufacturer. My meter box is full of murky water. The meter readers have a plastic tube which is sealed with clear plastic on one end. The meter reader places the tube on top of the register to get the read.
