Fire Hydrant Flushing

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.

Lombard Public Works Department to conduct fall hydrant maintenance

Sept. 19, 2016: Lombard Public Works crews will be performing the annual fall fire hydrant maintenance beginning the week of September 19, 2016.  Workers will visit more than 900+ hydrants over the course of a six week period.

The fire hydrant maintenance program is a vital part of the Village’s water pumping and water distribution system maintenance schedule.  Crews will be concentrating their efforts in this program for approximately five to six weeks.

During hydrant maintenance each hydrant is thoroughly inspected, oiled, and port caps are greased to ensure proper operability. This process continues to ensure that fire hydrants can be operated by the Fire Department and Village repair crews in a time of need.

Village maintenance crews will be focusing their efforts from Maple Street to Roosevelt Road to also include The Manor Hill and Pinebrook Subdivisions.  Please refer to the associated map for further details.
