Hydrant Flushing and Waterline Maintenance


You may notice Water Department crews working at fire hydrants and see water running down

the street. Your first thought may be that we are ignoring our own philosophy of conserving

water. We flush water lines through the use of fire hydrants, which is an

important preventive maintenance activity. Although it may appear to waste water, the process

is part of a routine maintenance program necessary to maintain the integrity of the water system

allowing us to continue to deliver the highest quality water possible to our customers.

As a result of the line flushing process, residents in the immediate vicinity of the work may

experience temporary discoloration of their water. This 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 crews have been flushing in your neighborhood, clear the pipes in your home

by running all water faucets for a few minutes.


Q: Why does the water system need to be routinely flushed?

A: The city’s water distribution system is a complex network of pipes and storage reservoirs

where sediment or deposits may naturally accumulate over time. If not removed, these materials

may cause water quality deterioration, taste and odor problems, or discoloration of the water.

Water may also stagnate in lesser used parts of the distribution system. This can result in

degraded water quality.

Q. When does flushing normal occur?

A. Normally, flushing takes place for approximately a two week period during early spring and early fall.

Check the Service Advisory page to see if a flushing has been scheduled, usually during May and October.

Q. What should I do when I see city crews flushing hydrants in my area?

A. If you see a city crew flushing hydrants, PLEASE DRIVE CAREFULLY.
