FESS Operations has tentatively scheduled a sitewide domestic water flush for Saturday, June 29, and Sunday, June 30, with rain dates of July 13 and 14. This annual event starts at approximately 6 a.m. and ends at roughly 6 p.m. each day.

During this time it is not unusual to notice an excessive amount of water on the roadways, standing puddles around fire and flushing hydrants, lower-than-normal domestic water pressure, discoloration in the water and, for those monitoring the facility incident reporting and utility system, low-pressure alarms as well. Typically, not long after each area has been flushed, the water pressure returns and discoloration clears up. In previous years, this process has had no ill effects on laboratory operations, and we anticipate this year to be the same.

FESS Operations asks everyone to be mindful of personnel performing the flushing during the above-mentioned dates, as a portion of their work will be performed in the roadways around Fermilab. Thank you for your consideration during this time.
