Lombard Fire Department crews will be performing annual fall fire hydrant flow testing beginning the week of September 28, 2015. Testing crews will visit more than 500+ hydrants over the course of a six week period.
The fire hydrant testing program is a way to evaluate the Village’s water pumping and water distribution system. Data gathered from this program benefits the Fire Department, the Fire Prevention Bureau, and Public Works. Testing crews will be concentrating their efforts in this program for approximately six weeks.
During hydrant testing, pairs of hydrants are thoroughly inspected and operated. Flow readings are taken to evaluate system capability to provide sufficient water supply for fire suppression crews during a fire, commercial and residential water needs, and Public Work’s Water Department needs.
During hydrant testing, residents may experience the following conditions; a temporary drop in water pressure when crews are in the area, water may be rusty (a reddish color caused by iron deposits), cloudy or “milky” water (caused by undissolved oxygen in the water that will dissipate within a few minutes). These conditions do not affect the quality and safety of the water, only appearance.
If you experience discolored or cloudy water, shut off the water and wait several minutes then run the cold water for a few minutes or until the water clears. Avoid doing laundry during hydrant flushing; white clothes may become stained if the water is not properly cleared first. Wash a load of dark clothes first before doing bright or white clothes. If water pressure or flow seems low, check the faucet aerators screens for sediment.
When you see a testing crew in your area, avoid running tap water and washing clothes until the flushing is completed. Drive carefully around any open running hydrant, watch for Fire Department personnel, and keep children away from the open hydrants and testing crews. Please feel free to call the Public Works Department at (630)620-5740 with any questions or concerns.
