To: All Campus Domestic Water Users Fr: Stanford Utilities Division Re: Annual Flushing of Water Mains - Possible Water Discoloration

The Water Department will open fire hydrants to flush out sediment that has collected in the water mains during the past year. This flushing program is a standard operating procedure for water departments. Flushing the mains may cause some slight but temporary reduction in water pressure and possible water discoloration. However, your water remains safe for drinking. We suggest you refrain from doing projects (laundry) that may be impacted by temporary sediment in the water while the water lines are being flushed in your particular area (see attached map). The schedule for flushing is as follows: Zone 1 (Residential area-south of Campus Drive East and Mayfield Ave.) Zone 2 (Central Campus and Academic areas-approximately within Campus Drive loop, additionally north to Sand Hill Road and between Bowdoin St. and Mayfield Ave.) For additional information, please call the Water Department at 723-1300 or Utilities at 723-9747. We appreciate your cooperation.
