Nipawin residents can expect a boil-water advisory to remain in place for at least another week.

The north-central Saskatchewan town was placed under the precautionary drinking water advisory on Nov. 18 because of dropping chlorine levels. Town officials aren’t yet sure what’s causing the problem, but said the issue should be fixed by Dec. 4.

No one has been reported sick so far, but residents are warned to boil water for at least a minute before drinking it. The water can be used as is for washing or bathing.

Chris Hudyma, the town’s interim economic development director, told CTV News it’s no secret Nipawin needs a new water treatment plant.

The town has been raising funds locally over the last several years for a new facility. Officials were recently hoping to secure government funding, but the funding process is stuck between the recent federal election and the next provincial election.

Town representatives are hoping to meet with Saskatchewan’s Water Security Agency and the Ministry of Health soon, Hudyma said.

A new plant would likely cost about $20 million.
