As snow melts and flows into the North Saskatchewan River, it brings with it large quantities of sediment containing decomposing vegetation and other organic materials washed off the land.
During spring runoff, sediment, vegetation and other organic materials give the water a musty or earthy smell. We prepare for spring runoff in advance by adjusting our treatment process to neutralize odours; however,
you may still notice a temporary change in the smell or taste of the drinking water.
The timing of spring runoff depends on the weather and temperature. While we don't know exactly when spring runoff will occur each year, we're always prepared for when it does. We adjust our water treatment process by adding powdered activated carbon in the first stage of water treatment. The activated carbon helps remove odour-causing compounds and is then removed by sedimentation.
Other than a slight odour or taste during spring runoff,
you shouldn't notice any changes to your water's appearance. If you do, or you notice a change you think is unrelated to spring runoff, please contact us at
