    Fire Hydrant Flushing

    Will Hydrant Flushing Affect Your Water?

    If you are using water when the fire hydrant flushing process is occurring in your neighborhood, the water that we are scouring out of the water distribution system could be drawn into your home’s plumbing system. Although the water may be discolored, smell different and/or have a slightly different taste, it is safe to use. 

    If water gets into your ice maker or laundry while we are flushing hydrants in your area, there are some simple remedies. For ice, after the water returns to normal, discard the discolored ice and the new ice will be fine. For most laundry loads, you may not even notice a change; however, white or light colored laundry may be affected.

    Why Do We Flush Fire Hydrants?

    The water distribution system consists of hundreds of miles of water main and thousands of fire hydrants, and each of those hydrants need to be operated periodically to lubricate the internal mechanisms and check the overall functionality. If a deficiency is discovered during this inspection, most maintenance can be performed immediately. The end result is that the fire hydrants in your neighborhood are available for fire protection if there is ever a need.

    Water chemistry can be very complex. Temperature and time can change how water reacts with the water main. Water mains are made of many different materials including cast iron, ductile iron, concrete and polyvinylchloride (PVC).  Flushing the water distribution system helps to remove sediment and deposits that may have attached to the walls of the mains or simply settled out of suspension. This is a standard procedure and the water is dechlorinated to protect the environment.
