Meter upgrade scheduli​ng website​ via city's contractor, UMS

The City of Ann Arbor continues its city-wide residential water meter replacement and service line material verification project. Despite a late start to the project due to COVID, the project is on track to be complete by the end of the year.  The contractor for this project, UMS is following strict COVID-19 safety procedures. State COVID restrictions are continuing to lift in the coming weeks, however, residents do have the opportunity to defer replacements if they are not comfortable allowing contractor access to homes. If you receive a scheduling letter and wish to temporarily delay the replacement, please use the contact information in the letter to make your request. If you previously requested a deferment and now feel comfortable with having the work completed, please call UMS call center at 844.741.​6248 to schedule an appointment.

COVID-19 impacts

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

  • physical distancing
  • face coverings
  • use of gloves
  • routine cleaning and disinfecting of equipment
  • daily temperature checks and screening​​
We understand that some may still feel uncomfortable scheduling an appointment at this time. If so, please contact UMS to​ request temporarily delaying the installation.


To accomplish these upgrades​, the city has contracted with Utility Metering Solutions (UMS), whose professional staff will perform the upgrades. All UMS staff have undergone background checks and they will carry identification and drive marked vehicles. The project will be carried out by sectioning the city into different upg​rade regions with occupants and property owner’s receiving detailed scheduling instruction and work details by mail. 

During the installation of the upgraded meter, several important inspections will also be conducted. First, UMS installers 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. ​​
