Water can appear discolored or cloudy whenever there is a large draw of water from the water main, which is relatively common near water main projects. This can occur when water valves are opened and closed, when there are water main breaks, and when hydrants are flushed or used by the Fire Department.
Naturally occurring mineral deposits that accumulate within the water main get stirred up and become suspended particles, thus producing the discoloration in the water. Discolored water is temporary, and while unappealing, it is not harmful.
Residents should run the cold water faucet closest to the meter (usually located in the basement or outside hose bib) for several minutes until the water runs clear. If the water does not clear after 20 minutes of flushing, contact the Department of Public Service at (248) 246-3300. Residents should avoid running hot water or washing clothes while water is discolored.
