City of Brockville provides update on seasonal watermain flushing program

The City of Brockville is warning residents that they may notice temporary changes to their water service over the coming weeks and months as the City of Brockville continues its annual watermain flushing program.

The seasonal maintenance program got underway on April 1, 2026 and is expected to continue through September. Crews have been working on weekdays between 7 a.m. and 3 p.m., moving through neighbourhoods in stages to help maintain the city’s water distribution system.

In an update provided on Monday, Jul.6, the City explained that water main flushing is a key part of its preventative maintenance program, helping remove sediment and mineral deposits that accumulate inside water pipes.

The process also allows crews to “verify the proper operation of fire hydrants and ensure adequate flow for fire protection,” according to city officials.

To date, crews have completed all hydrants south of Highway 401 and west of Park street, along Bethune Street, moving eastward from King Street to Highway 401.

According to the release, the program will now begin in neighbourhoods north of Reynolds Drive, between North Augusta Road and Oxford Avenue, before moving through other areas of the city over the coming months.

“We appreciate your patience as we perform this essential maintenance to ensure the continued delivery of safe, high-quality drinking water,” stated city officials.

As crews work in different areas of the city, residents may experience temporary discoloured water or slight fluctuations in water pressure.

City officials are reiterating that cloudy or rusty-looking water is caused by sediment being stirred up during the flushing process and is considered an aesthetic issue rather than a health concern.

Residents are encouraged to check that their water is running clear before using washing machines or dishwashers. If discolouration occurs, the City recommends running a cold water tap without a screen for five to 10 minutes, or until the water clears.

To help prevent sediment from entering household hot water tanks, residents are also advised to avoid using hot water while discoloured water is present.
