Water Meter Upgrades

The City of Ann Arbor's water upgrade project is at a critical juncture. ​

Despite a late start and difficulties caused by the COVID-19 pandemic, the project has upgraded 83% of those meters in service. This has been done, in large part, due to city staff and our contractor, Utility Metering Solutions (UMS) following strict COVID-19 safety procedures. In addition to the upgrades, the city has also been inspecting water lines to complete the service line inventory to comply with Michigan's new Lead and Copper Rule as well as conducting a cross connection/back-flow survey as required by the state.

This upgrade work is not optional and must be completed to ensure functioning meters and meeting state regulations. 

For those who still need to schedule an appointment or request deferment due to the COVID pandemic, please contact Customer Service by phone at 734.794.6320 or by email at [email protected]

  • A survey to gather information on potential cross connections prior to installation.

  • An examination of drinking water service line material at the time of upgrade.

  • The installation and inspection process will take ​approximately 30–60 minutes, with interruptions to water service lasting no more than 15–20 minutes.

COVID-19 precautions 

We understand the trepidation some might feel letting contractors into your place business or residence. Staff is taking every precaution to keep you, your employees and residents safe by following these COVID-19 safety procedures:

  • physical distancing
  • face coverings​
  • daily temperature checks and screening​​


Meter upgrades have been completed for 2021. The city plans to reach out to those who previously requested a COVID deferment early in 2022 in addition to completed upgrades on non-residential meters. 

During the installation of the upgraded meter, several important inspections will also be conducted. Fir​st, staff will be inspecting the lines that run to and from the water meter to help the city comply with Michigan’s new Lead and Copper Rule.​ These rules state that city’s must verify the material of service lines and determine if they qualify to be replaced. Second, installers will collect and verify information for a cross connection/back-flow prevention control survey (residential properties only) as required by the State. A cross connection is any arrangement of pipes in a building’s plumbing system that could result in backflow of contaminants into the public drinking water supply ​system. The best example of this cross connection is your garden hose. For this survey to be successful, occupants will also be asked to answer several questions during the installation appointment.​

The installation and inspection process should last approximately 30-60 minutes, with water service interruption lasting no more than 15-20 minutes. As part of the inspection and verification process, photos will be taken. These photos will only be used to document the installation of the new water meter and for the inspections.​​​

The upgraded meters utilize the same wireless and data transmission technology that has been employed as part of our water meter system since the early 2000's. ​​
