Hydrant Flushing

What is the purpose of hydrant flushing?

You may notice Water Utility technicians working at hydrants and see water running down the street. The Utility flushes water lines through the use of hydrants, which is an important part of routine maintenance activity. Not only does it provide fresh, clean water, but the technicians are inspecting and exercising the hydrant to improve operation in the event of an emergency.



As a result of the flushing process, residents in the immediate vicinity of the work may experience temporary low water pressure or discoloration of the water. The discoloration consists primarily of harmless silt and air and does not affect the safety of the water. If you experience discoloration in your water after technicians have been flushing in your neighborhood, clear your pipes in your home by running cold water through your faucets for a few minutes. We recommend using a faucet without an aerator such as the bathtub or an outside hose bib. Many residents use a container to catch this water and use it to water their garden to avoid wasting the water. 

When Does Flushing Occur?

Hydrant flushing is conducted from 7:00 a.m. to 3:00 p.m., during the months of April and May, or as necessary to ensure satisfactory water quality. 

What should I do when I see technicians flushing?

If you see technicians flushing, please slow down and drive carefully. Residents are urged to avoid water use when the flushing occurs near their neighborhood for approximately one-half hour to allow any fine particles to settle down. 

What should I do after the flushing?

If hydrants are being flushed near your home, please DO NOT USE WATER for approximately one-half hour to allow any fine particles to settle down.  If you run water and notice discoloration, DO NOT RUN YOUR HOT WATER.  Wait 15 minutes.  Then flush out the rusty, discolored water through your COLD water faucet.  Although the water may temporarily be somewhat discolored, it is safe to drink.  The discoloration is the result of rust and mineral deposits being scoured from the inside of the pipes. Your patience and cooperation is appreciated and will benefit all water customers.
