A damaged segment of water main in northern Macomb County has been replaced and is expected to be returned to service by the end of the week.

The Great Lakes Water Authority on July 5 identified a leak in the section of 36-inch transmission main on Gratiot Avenue between 24 Mile and 25 Mile roads in Chesterfield Township. The damaged segment was replaced over the weekend, and the main was disinfected with chlorine and flushed, GLWA said in a news release.

GLWA Water Quality conducted the first required set of tests, which came back clear Monday morning. Results of the second set of water quality testing are expected back within 24 hours.

At the completion of water quality testing, GLWA said it will work with the impacted communities of Chesterfield and Lenox townships and the village of New Haven to return the regional system to normal operations, which will involve opening and closing valves in the system that were manipulated when the leak was discovered to main system pressure.

The work may cause fluctuations in system pressures and could also cause residents and businesses in the impacted communities to experience discolored or cloudy water.

GLWA expects to return the main to service by the end of the week.

For water pressure or water quality concerns in any community, residents and businesses should contact their local municipality’s department of public works.
