A boil water advisory for the city of Fort Saskatchewan continued into Sunday.

The advisory was issued Saturday after a reservoir failure left the city of nearly 20,000 people without water for an hour.

The failure created an opportunity for a contaminant to enter into the system, though the city says there is no indication of the water being contaminated.

As a safety precaution, Alberta Health Services issued the advisory until water samples could be tested.

First results of the test are expected by 5 p.m. Sunday.

At that time city officials will indicate whether the advisory has been lifted or if it continues.

Residents are asked to check the city's Twitter account, the update line at 1-866-653-9959 and the city's website www.fortsask.ca, for updates at that time.

In a release, Mayor Gale Katchur explained why the city's siren system was not used to notify residents of the advisory.

"The siren is only used when a shelter in place emergency occurs. If we use it for everything, it will not be effective when we need it for a shelter in place emergency, which this clearly was not," Katchur said.

Residents are reminded to boil water for at least one minute prior to doing any of the following:

  • Drinking
  • Brushing teeth
  • Cleaning raw foods
  • Preparing infant formulas or juices
  • Making ice

Water used for bathing or washing clothes does not need to be boiled.

Grant Schaffer, the city of Fort Saskatchewan's public works director, said a failure in the control panels caused a loss of power in the reservoir, shutting down the electric pumps.
