Performed one to two times a year, water main flushing typically takes place in the Spring and Fall. As a result of the flushing procedure, residents in the immediate vicinity of the work may experience temporary discoloration of their water. This discoloration consists primarily of harmless silt and precipitates and does not affect the safety of the water.
What should I do if my water is discolored?
If this discoloration occurs, simply run your cold water faucets for about 5 minutes to make sure the water is clear. If it doesn't clear up after a few minutes, wait for an extended period of time (up to 2 hours) and try running the cold faucets again. If the water does not clear up within two hours, please notify the City of Waconia Utilities Department. It is recommended that you do not do laundry during flushing periods to avoid stained clothing.
Why do we flush hydrants?
Water moves slowly through the underground water distribution system. This slow movement causes sediment like rust and minerals to build up over time and accumulate along the inside of the water pipes. Brown water is typically iron and manganese that is showing up in the system. Flushing of the fire hydrants increases the movement or velocity of the water through the water mains, thus helps to remove any sediment from the water mains and assures consistent water quality. Additionally, as part of the flushing process every fire hydrant in the water system is operated to ensure that it will operate properly in the event of a fire.
Isn’t flushing a waste of water?
Residents who notice Waconia’s utilities crew working at fire hydrants and see water running into the street may think that the City is ignoring its own philosophy on conserving water. The process of periodically flushing fire hydrants, however, is an important preventive maintenance activity. Although it may appear to waste water, this process is part of a routine maintenance program necessary to maintain the integrity of the water system and to continue to deliver the highest quality water possible to our customers.
Hydrant flushing will begin April 21st. Please see the detailed map HERE as flushing will take place in numbered order.
