Normal Hydrant Flushing

Here's to the Town of Normal employees who patiently wait while fire hydrants are "flushing." The hydrants have to be flushed regularly to keep them in good working order and the town staff always alert residents as to when they can expect this in their neighborhood.  It is done overnight and, from what I've seen, takes quite some time because each hydrant is left flushing for a surprisingly long amount of time (not sure exactly how long, but it seems like at least 30-45 minutes).  I wish the water could be diverted onto grassy areas instead of letting it run along the curb. Maybe someone can develop a diverter device to do this.
