Water can appear cloudy and/or rusty whenever there is a large draw of water from the water main. 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.
Discolored water is usually temporary, and while unappealing, it is not harmful.
If your water is cloudy or discolored, 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.
