City of Duncan Annual Water Main Flushing

Please be advised that the City of Duncan is conducting annual water main flushing from March 18 to May 31, 2024.

Annually each spring, water is flushed through the water pipe system and out a fire hydrant. This program is intended to clean water distribution pipes of sediment that builds up over time.

Any discolouration of water during the flushing period can be resolved by running a cold-water tap.  City staff will erect sandwich boards daily near the site of the flushing.

If you have any questions about the annual water main flushing, please contact Public Works at 250-746-5321 or
