Health Canada and the World Health Organization (WHO) both say there is no risk to your health if your drink water containing asbestos fibres.
Water travels through all kinds of pipes to get to any particular service, which could include asbestos pipes. In 2022, we tested the water in our system and found no asbestos fibres in the water. Lethbridge has 177 kilometers of asbestos-cement pipe, which represents 29% of the total system.
The City is committed to the safe handling of asbestos materials and the practical removal of asbestos-cement pipe at every opportunity and per the lifecycle program.
Asbestos-Cement (A/C or Transite™) pipe was introduced in North America around 1930 and is made of asbestos fibers, silica sand, and Portland cement. The City of Lethbridge used A/C pipe quite extensively within the thirty years of 1950 - 1980. The City of Lethbridge crews that work on A/C pipes follow many safe work practices in this regard. A/C pipe is rarely installed anywhere in North America today, primarily due to the fear of working with asbestos and because PVC pipe has replaced it as an inexpensive, lightweight piping material.
Health Canada and WHO have concluded there is no risk that asbestos ingested through water is harmful to your health.
