Hydrant flushing

Learn more about hydrant flushing and dates when flushing will occur.

The City’s hydrant flushing program is a necessary maintenance process that removes particles and minerals that form over time inside water pipes, thereby widening the water’s pathway to flow. Flushing ensures a continual, adequate supply of potable water for necessary uses while meeting public safety needs through fire prevention (under Ontario Fire Code, Ont. Reg. 730/81) and confirming that water supply systems, including valves and hydrants, are in good working order. 

Visit our water quality page for tips on clearing discoloured water. During this time, the City recommends that laundry be done after flushing hours to avoid staining clothes.
