The city flushes all hydrants annually, typically in April. It takes City crews about three weeks to flush all the hydrants. Flushing creates a scouring velocity in the water mains in order to remove any settled impurities. The flushing operation also serves as a check for proper fire hydrant function.
If discolored water is experienced in your home or business, it is usually temporary and will clear up in a couple of hours. Running the cold water taps should help speed up this process. Contact the City Utility Dept. if the water does not clear up so additional flushing can be scheduled.
Fire hydrants have over 50 unique parts and require periodic lubrication, and they are designed to break off safely in the event they are struck by a vehicle. There are over 2,200 fire hydrants in Chanhassen!
