Water Main Flushing & Hydrant Maintenance

The annual flushing and maintenance project will take place from Monday April 24 through Friday May 26, 2017.


The Town of Comox wishes to advise residents that the Public Works Department will be proceeding with the annual flushing of water mains and the annual maintenance of the Town of Comox fire hydrants.

This program will commence on Monday, April 24, 2017 and will be completed by Friday, May 26, 2017. All work will take place from Monday to Friday between 8:00 am and 4:30 pm.

This program may result in temporary but harmless slight discolouration of the water. Should this occur, running a cold water tap for a period of time will remove any discolouration. Where practical, residents should avoid washing laundry during operational hours as to do so could result in discoloration of clothes.

Motorist are asked to slow down and use caution when approaching flushing crews.

Town drinking water originates from Comox Lake, and the source water can contain trace amounts of sediment that can settle out of the water and build up in our water lines over time. To remove any built-up sediment and ensure a turn over of any stagnant water in our mains, each spring Public Works systematically goes through the Town flushing water out of each of our 450 plus fire hydrants and blow-offs (on dead-end lines). This takes around 15 minutes per hydrant and overall the annual flushing process uses an amount of water that is roughly the same as annual water use from 40 single-family homes. Hydrants used also receive their annual servicing, ensuring that each is ready to be called upon during a fire.
