This is the season where the extreme weather can cause water main breaks. This is not an uncommon occurrence and we do our best to limit the amount of disruption to our residents' water service.  Above all, we take our delivery of safe drinking water to our residents extremely seriously.

Occasionally, the operation of valves to control the flow of water at the break location may cause some sediment to become dislodged in the water mains and cause discoloration of the water. If this does occur, please run water in your bathtub or utility sink until the water clears.

Also, utilizing fire hydrants for fire protection can stir up the sediment, as well.

Periodically, the Department of Public Works conducts routine flushing of the City's fire hydrants. Hydrant flushing removes harmless mineral deposits that have accumulated in the water mains. This process also helps identify hydrants and valves in need of repair. During this flushing process, residents may experience discolored water and possibly a temporary drop in water pressure. The discolored water presents no health hazards.  It may, however, look cloudy or rusty. The end result is a cleaner and more efficient water transmission system for all residents and businesses in Oak Park.

If you do experience any discoloration we recommend running the cold water in the laundry tub or bathtub for about for about five minutes until the water color appears clear. It is recommended that you wait for the water to become clear before washing clothes or dishes. 

Under these conditions, even though the water is discolored and has some sediment, the water still contains chlorine residual and is safe. 

If, for any reason, you suspect that your water is unsafe, please call the Department of Public Works at (248) 691-7497 so our crews can investigate. Upon investigation, if for any reason we suspect the water is not safe, we will issue a boil water alert and notify everyone as soon possible through email eblast, social media posts (Facebook and Twitter @CityOfOakPark), and emergency alerts on the website (
