The 2023 McDougall Creek wildfire caused serious damage to the Rose Valley reservoir, which provides source water to more than half of West Kelowna residents through the Rose Valley Water Treatment Plant. During a presentation to city council this week, Interior Health medical health officer Dr. Fatameh Sabet said that damage makes it harder to treat water coming from the reservoir. “We know the land surrounding the Rose Valley reservoir has been contaminated because of the wildfire in 2023 and it means the contaminated source of water can be harder to treat because of the sediment, nutrients, metals and organic matter as a result of burned material,” said Dr. Sabet. “Fortunately, the Rose Valley Water Treatment Plant was not damaged from the fire and it has been very helpful to compensate for damage to the watershed.” The plant ensures water is safe by not only controlling levels of manganese and disinfection byproduct, but other perspectives as well.
