As of 3:30 pm, on Friday, August 10, 2018, the Precautionary Boil Water Advisory for impacted homes, (see map), has been lifted.  Impacted home owners should use the following guidance to flush pipes before water consumption:
  • Flush pipes at home for 5 minutes by running the cold water tap at all faucets, for a residence with multiple levels, start at the top of the house.
  • If discolored, run water until it is clear
  • Follow manufacturer’s instructions for appliances such as water filters and water softeners.
  • Dispose of ice from automatic icemakers, make and discard 3 batches, then wash and sanitize trays.
  • Run enough hot water to completely empty the water heater tank; water will feel cool.
