Water Meters Overview
The City of Santa Rosa has over 50,000 water meters to measure the volume of water for billing purposes. Every connection to the Citys distribution system is metered, even temporary connections. The Citys meters range in size from 5/8 inch to 6 inch to accommodate households to industrial users. All of the water meters register in gallons so it is easy to determine the water use and if there is a leak.

How to Read Your Water Meter
Your water meter is normally located at your front curb, housed in a concrete box. Reading the meter is similar to reading a car odometer. The meter measures volume of water in gallons. The first digit to the right is a fixed zero so you need to locate where the red needle is pointing. The meter to the right shows the needle is pointing to the 2 which is 2 gallons. On some of the meters the City uses may not have a red needle, instead these meters register down to a tenth of a gallon without a fixed zero.

To find out how much water you have used in any given period, write down the entire meter reading, including the red needle if the meter has one. For example, the meter shown would read 50,382 gallons. Reading the meter again later, subtracting the previous reading from the current reading gives your household water use in gallons. The meters also incorporate a small triangle or disk on the face of the meter that is used as a low flow indicator. It will rotate with even a very low flow through the meter. This should not be moving if all of your water using devices are off. If there is movement, this could indicate a leak on the property.

Automated Meter Reading
Out of the 50,000 meters the City has 12,000 are read by either touchread or radioread methods. Touchread is a probe that is in the meter box lid that the meter reader touches with a wand device to read the meter. Radioread is a antenna that is mounted in the meter box which is read by a vehicle driving by the meter.

Construction Meters
The City meters all connections to the distribution system whether it is a permanent or temporary connection. Typical uses of temporary meters include site water for construction purposes, testing and flushing water mains in new developments, and filling water trucks.
