Water Quality Advisory

Update #5:  May 8, 3:00 p.m.

  • Approximately 2500 homes in the City remains under a Water Quality Advisory. Maps and a list of the street addresses under advisory are available on the “Latest News” section of the City’s website.
  • All results-to-date have indicated there is no contamination. Additional testing is required and ongoing.
  • The City expects to review the situation with Interior Health around noon on Tuesday, May 9 and issue an update to the public.

A water quality advisory is the lowest-level notification and is used in situations where the general public health threat is modest.  Additional precautions can be taken by individuals with weakened immune systems, people over 65 years of age, children under 2 years, and people with chronic illnesses.


At just after 12.30 a.m. on May 6, the automatic monitoring for the City’s water distribution system reported a significant drop in water pressure at the Randolph Road chlorination station and the Duncan Avenue reservoir. This was followed shortly after by a water level drop in the Evergreen reservoir, which indicated a major water loss from the system. Water and public works crews immediately began an intense investigation to determine the location of the break while also commencing procedures to restore the supply of water to the affected part of the system.

At around 5:00 a.m. crews concluded that the break had occurred under Ellis Creek and took steps to isolate the break to stop the loss of water to the system and by 7:00 a.m. the break had been isolated. Regular functionality was restored to the system during the next hour.

At 8.30 a.m. the City contacted Interior Health to inform them of the situation and the precaution was taken to prepare a Water Quality Advisory notice to the public just after 9:00 a.m.
