Advanced Metering Infrastructure (AMI) Project

CCWD Advanced Metering Infrastructure (AMI) Project

Calaveras County Water District’s (CCWD) Advanced Metering Infrastructure Project is currently underway, and will upgrade all the water meters in the district and improve CCWD’s meter reading system. CCWD will replace all 13,000+ water meters with new, highly-accurate meters. These advanced meters will send usage data to CCWD through a wireless network. This technology is known as Advanced Metering Infrastructure (AMI).

Customer Billing

Installing AMI meters is an exciting opportunity for the District to provide customers with real time water usage information. During the transition, CCWD is working diligently to assure customers are billed accurately.

CUSTOMER BILLING INFORMATION: The bills most customers are now receiving reflects consumption utilized on your new AMI meter. Although you were not charged for the new meter and your water rate did not change at the time of the upgrade, you may see an increase in your bill because the new meters record consumption more accurately than the old meters. As water meters age, they tend to run slower and may not measure all of the water going through them. Most of the old water meters owned by CCWD are more than 20 years old and at the end of their functional life. Therefore, depending on the age and accuracy of your current meter, you may see an increase in your bill based on more accurate readings.

If your property does not yet have an AMI meter, you will continue to be billed consumption from your old, analog meter until it is replaced. For questions about billing, please contact customer service at 209-754-3543 or

Current Project Status

Network Installation: Contractors are currently setting up network installation equipment throughout the District. This includes connectors, repeaters and solar panels that are vital for data to be transferred from your meter to the CCWD administrative office. All networking equipment is placed within public utility easements or on CCWD property. Network installation should be completed by Spring, 2022.

Meter Installation: Meter installs began the week of August 23rd in the Ebbetts Pass Service Area. Keystone Utility Systems is our subcontractor who are conducting meter installations throughout the District.  Keystone has completed most meter installs throughout the District, and all meters are scheduled to be installed by Summer, 2022.  When your new meter is installed, a door tag will be placed on your door informing you.

About the AMI Project

Currently, CCWD utilizes dated manual-read meters. District staff read the meters every two months. The AMI system will use advanced meters that can send usage data through a wireless network to the CCWD office. The meters will send data use in real time, as needed (usually once per day). A new software system will keep track of usage and averages for each customer. All data is collected securely and does not contain a customer’s personal information.

How AMI Works

An advanced metering system uses a wireless network to provide detailed data that is easily accessible online by customers and CCWD staff.

  • Advanced water meters transmit real time water use data over a wireless network.
  • CCWD Staff can access data and more detailed reports about water use throughout the district.
  • Customers can access data from a web portal

Meter Accuracy Test

Put your highly accurate AMI meter to the test.

The advanced technology of AMI provides water agencies and customers with the confidence of highly accurate metering of water consumption. A simple way to gauge your meters accuracy is to conduct a five-gallon bucket test. All you need to do is grab a five-gallon bucket, a hose, and locate your water meter to mark a beginning and ending read. Here is a quick video tutorial on how to conduct a five-gallon bucket test.

*** Please note that a five-gallon bucket holds a little more than five gallons. Typically, five gallons reaches one inch below the top of the bucket. If you want to be more precise, you can mark out exactly five gallons in your bucket using a measuring cup (16 cups = 1 gallon). Another way to get exactly five gallons is to use a bathroom scale.
1 gallon of water = 8.34 pounds, 5 gallons = 41.7 pounds plus the weight of the empty bucket. Therefore, weigh the bucket first, and then add 41.7lbs to that value.
