Have you received a notice? If you have received a notice, The City is advising that no water be used during the times specified on the notice.
In addition, the City is suggesting that your shut off valve be turned “OFF” at your meter, to prevent any water being used accidently.
The Process: Swabbing involves scouring the watermain with foam swabs and high-velocity water. These swabs are injected at a fire hydrant and pushed by water through the watermain, then removed further down the watermain through another hydrant. The hydrants are left open until the water runs clear.
Impacts on Customers: The procedure requires that water be turned off briefly to affected homes or businesses while the section of watermain is isolated and cleaned. During swabbing, customers are asked not to run water.
Residences: Depending on their location, affected homes may be impacted by this activity more than once; however for every occasion those impacted are notified via a placard attached to door knobs of residences approximately two days before the planned swabbing activity.
Businesses: Businesses affected during the swabbing procedure will be visited in person by a representative of the City before project commencement. This visit is followed up with an email detailing the dates and times the business will be impacted. This email notification will occur approximately two weeks prior to the planned swabbing activity.
Watermain swabbing occurs throughout the day, evening and weekend.
Residents and businesses may experience some water discoloration for short durations following outages and should follow these guidelines once watermain swabbing is completed:
The water may be cloudy because air captured in the water forms tiny bubbles. These bubbles are harmless and will disappear if the water sits for a few minutes.
If water is still discoloured after two to three hours, please call the Water Operations Branch at 705-792-7920.

Watermain flushing is a maintenance activity performed regularly. During watermain flushing, you will typically see is Water Operations staff operating and monitoring two hydrants. This involves running water from two hydrants at the same time; by moving water at a higher-than-normal velocity, scouring occurs inside the watermain.
Typically, households should not experience water discolouration during watermain flushing, however this can sometimes occur. If you notice your water is discoloured, please run the cold water tap on your laundry tub or bath tub for approximately 5–10 minutes to clear any discolouration. If the water is still discoloured after this time, please contact Water Operations: 705-792-7920 or
After-hours, please call 705-726-4242 and press zero for assistance; appropriate on-call staff may assist you.
Hydrants in Barrie are yellow or red. Yellow hydrants are public (municipal) hydrants, found in front yards and all along streets; they are used for
fire protection and maintenance of the drinking water system. Red hydrants are privately owned, not maintained by the City, and are the responsibility of the property owner which they reside.
You may see City staff operating hydrants on occasion. There are many activities that can be performed through proper hydrant operation and maintenance, including watermain flushing, swabbing, sampling,
pool fill, and repair/replacement.
City staff take great pride in the appearance of the city, so during the summer months you may see staff or contractors at hydrant locations performing activities such as:
Snow removal from public hydrants is performed by a contractor obtained through the City. The crews work primarily throughout the evening and/or early morning hours to remove snowpack from the hydrants to ensure safe operation of the hydrant is maintained in the event of
For those property owners with a fire hydrant: please be mindful. Residents are asked to assist by helping to keep fire hydrants on their properties clear of snow. Hydrants should have a clearing of one metre (3 ft.) all around and there should be a clear path to the street to ensure firefighters can readily access them.
