The fire hydrant flushing program is a vital part of the Village’s water pumping and distribution system maintenance schedule. Hydrants are flushed twice a year, in the 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 picture of system performance during a peak usage event.
