The City of Macomb Fire Department will be conducting flow tests on numerous hydrants throughout the city this week as part of our ISO audit, October 5-October 9, 2026.
Please be advised that flow testing may cause some discoloration of water. This does not represent a health hazard.
However, customers are cautioned to determine if the water is clear before washing clothes (or any other processing) as staining may occur. If you experience discolored water, avoid using hot water until discoloration clears and run your cold water for approximately 5-10 minutes to clear your service line. Please report extended discoloration and any concerns to the Water Treatment Plant at 309-836-3916.
