April 14, 2023 update

The City of Ann Arbor's contractor, Utility Metering Solution (UMS), will be restarting meter upgrades in Ann Arbor next week. 3,000 or so customers will be receiving notification​ letters over the next few months notifying them of this critical work and how to schedule an appointment. ​


Working with our contractor, Utility Metering Solutions (UMS), the city has thus far replaced 87% of water meters. The City of Ann Arbor's water upgrade project is at a critical juncture. ​This upgrade work is not optional and must be completed to ensure functioning meters and meeting state regulations. 

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.​
