Brockville crews continue annual seasonal watermain flushing across city

Brockville residents in the city’s north end may notice discoloured water or temporary drops in water pressure in the coming weeks as crews continue the annual watermain flushing program.

In an release issued on Thursday, August 6, 2026, the City of Brockville provided an update on the seasonal maintenance program, which began in April and will continue through September. Crews have been working on weekdays between 7 a.m. and 3 p.m., progressively flushing different sections of the municipal water system.

According to city officials, watermain flushing is necessary to remove sediment and mineral deposits that naturally build up inside pipes, while also allowing crews to test fire hydrants and confirm adequate water flow for firefighting purposes.

Crews are currently working in the area north of Laurier Boulevard to Centennial Road, between Windsor Drive and Stewart Boulevard.

Residents in affected neighbourhoods may notice cloudy or rust-coloured water while flushing is underway. The city clarified that this temporary discolouration is caused by sediment being stirred up in the pipes and is an aesthetic issue rather than a health risk.

City officials recommend running a cold water tap for several minutes until the water runs clear before doing laundry or using a dishwasher.
