The flushing program may cause periods of discolored water and reduced water pressure in localized areas where flushing is being conducted. The discoloration is due to particles and minerals that have settled in the main being mobilized by the high velocity water before they are discharged through the fire hydrants. The water will remain safe to use and generally clears within a few hours after flushing has been completed. Residents should monitor their water prior to starting laundry, especially when washing white clothes.
Commercial customers, especially businesses that serve the public, should be aware of the water quality while flushing is taking place in their area. Due to the nature of the program, it is difficult to determine the exact day an area will be flushed; however, on average, each flushing set takes 1 to 3 days to complete, depending on the quantity of water mains to be flushed and the number of valves that are operated.
