June 26, 2018 -- City fire hydrant flushing is currently underway and should continue through Fall. A hydrant flushing program is very important to water quality. Over time, various materials such as corrosion products and organic materials build up in the mains of municipal water distribution systems. This buildup can cause water quality issues such as unusual tastes and odors and discoloration of the water.
During the flushing process, you may notice that your water is brown for a temporary period. There is no health hazard associated with the discolored water. Allow a few hours for discoloration to dissipate. To verify water is clear, run your cold water tap for a few minutes.
