Reintroduction of Fluoride to Local Water System

January 10, 2022

Windsor, ON: ENWIN Utilities Ltd. (ENWIN), on behalf of The Board of Commissioners of the Windsor Utilities Commission (WUC) announced today that it will reintroduce Fluoride into the local drinking water systems for Windsor, Tecumseh and LaSalle, effective January 12, 2022.

The Fluoride implementation follows completion of extensive tests recommended by Jacobs Engineering (Jacobs), including a treatability assessment, a review of Fluoride additives, as well a study using WUC’s pipe test loop to ensure no adverse effects to WUC’s corrosion control program. 

“We completed the pipe loop testing, as anticipated in 2021, but experienced a minor set-back in the implementation due to supply chain issues related to COVID-19,” commented Garry Rossi, VP Water Operations. “We have now resolved that issue, and our team is poised to begin introducing Fluoride.”

ENWIN will continue to monitor the pipe loop after the implementation to ensure pilot data is consistent with actual drinking water system sample results, and to collect further seasonal data.

"We are dedicated to ensuring the water we provide is safe and reliable," commented ENWIN President & CEO, Helga Reidel. "We have received a 100% rating on our annual audit by the Ministry for the last ten years, and we want to ensure we maintain our consistently high standards."

ENWIN and the WUC produce approximately 39 trillion litres of potable water, delivered to Windsor, Tecumseh and LaSalle annually.
