City workers will start flushing water in the Hart on Tuesday.
The work, which occurs each summer to maintain the system's quality, will be carried out between 7 a.m. and 3 p.m. from Monday to Friday until about the end of the month.
Residents may notice a slight drop in water pressure for a few hours each day as well as cloudy water as iron deposits get stirred up.
The water will remain safe to drink, the city said, but households may want to store some water for drinking and avoid doing laundry from 8:30 a.m. to 3 p.m. to avoid discolouration.
"The City of Prince George appreciates the patience of residents as work is completed on this important project," the city said.
