Hydrant Flushing in Hoquiam WA

The Public Works Department has established a preventative maintenance program to annually clean waterlines and check the operation of fire hydrants throughout the city. Public Works Department field crews operate fire hydrants to create high velocity flows that scour and clean the inside of waterlines. This type of activity, often called flushing, is a common utility practice used to improve water quality and maintain the distribution system. Minerals and other materials that accumulate in the lines are removed by flushing. This material is not harmful to your health but it can temporarily cause discolored water.

Flushing Begins November

Flushing is scheduled to begin the week of Nov 04, 2019 and will continue through the end of December. The distribution system contains 61 miles of pipe, it is expected to take approximately 45 days to complete the flushing. Flushing hours will be 6:00 a.m. to 4:00 p.m., Monday through Friday, excluding holidays.

  • Customers may notice discolored water or a change in water pressure when flushing is conducted in their area. When flushing is taking place, we recommend that customers check to ensure tap water is running clear before using it for drinking, cooking or clothes washing. Customers who experience some coloring or sediment in their water should let the cold water flow from their taps for a short time (5-15 minutes) to flush and clear their plumbing.
  • Flushing activities often involve release of large volumes of water from fire hydrants. Residents may notice this water flowing along the gutter line of the street and entering storm drains.
