City Of Monticello issued the following announcement on Apr. 15.
Spring Hydrant Flushing begins April 18! Every spring the City flushes out its water mains through the fire hydrants. This clears the water mains of sediment and minerals that settles in water mains over time. Staff also verifies that the hydrants are in good working order.
During flushing, deposits from water lines may create a yellowish to brownish discoloration of water in homes near flushing areas. While this water is safe for drinking, it may discolor laundry.
If you are experiencing discolored water, we advise you to hold off from doing laundry and run water until lines run clear. If this discoloration last longer than two days, residents are asked to call the City’s Utility Department at (763) 295-3170. https://www.ci.monticello.mn.us/Calendar.aspx
