Fire hydrants are located throughout the community and provide Orangeville Fire with access to water during fire emergencies. Orangeville has almost 1000 fire hydrants in total. All fire hydrants must be accessible at all times to help with emergency responses. Please do your part and clear snow around fire hydrants during the winter!

Flushing watermains

Public Works uses fire hydrants to flush the watermains on a regular basis. Generally, flushing is done on Wednesday between 8 a.m. and 4 p.m. We flush the watermains in order to minimize taste and odour problems that may occur. 

Please be aware that from April 1 to October 31, 2021 between 8 a.m. and 4 p.m. Monday through Friday each week, Orangeville Water Works staff will be completing fire hydrant flushing and maintenance programs. The programs are completed on a regular basis to ensure fire hydrants remain in good working order and that any accumulated sediments in the watermains are removed.

Due to possible sedimentation, the flushing may cause discolouration of the water, so please check your cold-water supply before use.  If discolouration does occur, run the cold water until it clears.

Users of the Orangeville and Mono water systems are also reminded that Water Works Staff will continue regular flushing of fire hydrants in selected areas on subsequent Wednesdays as part of an ongoing maintenance program.  Again, the water should be checked for discolouration before use on those days.


We open all fire hydrants at least once each year to ensure they are operating. This testing is typically completed over a four to six-week period in the spring. View our fire hydrant maintenance schedule to find out about upcoming flushing programs.
