Hydrant Flushing

The annual or semi annual flushing of water mains, via fire hydrants, is a standard practice in the water industry.  This is a vital maintenance process that improves water quality at the tap by removing accumulated minerals, sediment and tuberculation (a buildup common in iron pipes that reduces its ability to transmit water).  This also allows us to identify hydrants in need of repair.  Our Field Services Team will be in a clearly marked DPW vehicle and will conduct most flushing during the day but certain areas of the City will be flushed at night to minimize disruptions.  

Please review our progress by finding the hydrants in your neighborhood on this interactive hydrant map!

The flushing process can cause low water pressure and frequently disturbs the accumulated minerals and sediment in the water mains.  The quick release of water from a hydrant causes them to dissolve and temporarily discolor the water delivered to homes and businesses.  Although, the water is perfectly safe we recommend running a cold water tap for several minutes to help clear the discoloration before using it for drinking or laundry.  If you experience any discolored clothing due to hydrant flushing, please contact Water Resources prior to drying the items and we can offer solutions for stain removal.

What is a pumper port gate valve?  Excellent question! This valve allows us to shut down a failed hydrant without shutting off the water to residents.  Unscheduled water outages are inconvenient and costly, so we are very pleased to be utilizing this technology.
