The City of Calgary provided an update on the timelines for reintroduction of fluoride to its drinking water.
We have finished installing the equipment at both the Glenmore and Bearspaw Water Treatment Plants and are now in the commissioning phase. After undertaking the initial commissioning steps, we determined it will require additional time to allow us to ensure all equipment and systems are checked, inspected and tested to ensure they are all performing as designed.
As a result, the reintroduction of fluoride is expected later in the second quarter of 2025. We thank Calgarians for their patience and once we have a confirmed reintroduction date we will provide an update four weeks in advance.
The Council decision to reintroduce fluoride in the drinking water system was made after a plebiscite in the 2021 Civic General Election found 62 per cent support for fluoridation amongst voters.
The reintroduction of fluoride into the water system required infrastructure upgrades at Calgary’s two water treatment plants. Existing infrastructure had reached the end of its lifecycle in 2011 and was removed following Council’s decision to stop fluoridation.
Capital upgrades included:
- A retrofit of an existing building at the Glenmore Water Treatment Plant and installing the new fluoride equipment.
- A new building at the Bearspaw Water Treatment Plant to house the fluoride equipment.
