The fire hydrant flushing program is a vital part of the Village’s water pumping
and water distribution system maintenance schedule. Hydrants are flushed twice a year, Spring and Fall.
 
Each hydrant is thoroughly inspected and operated. Flow readings are taken to
evaluate system capability to provide sufficient water supply. Low flows may indicate a
water main valve is closed or not operating properly. Large volumes of water are moved
through the mains during flushing which pressure cleans the internal walls of the piping
and increases the main’s longevity.

The water pumping stations also benefit from hydrant flushing. As large volumes
of water are flowed through the system, the water storage tanks’ levels will fluctuate
more than they normally do. This allows the water operators to check pressure adjusting
and pumping stations’ ability to respond to these pressure fluctuations and gain an overall
monitoring of system performance during a peak usage event.
