City officials say access to a major water treatment plant in west Ottawa is at risk from the rising Ottawa River.
Cassels Street is the only road to the Britannia Water Purification Plant, and the military will be making sure it remains accessible, said city manager Steve Kanellakos.
"There's a section of that road that, if it becomes flooded, prevents us from bringing in the chemicals required to treat the water," Kanellakos said at Friday afternoon's update on the flood threat.
"We don't have the ability to stockpile enough chemicals in our [Britannia] water filtration plant to deal with the next three weeks, should we lose that road."https://www.cbc.ca/news/canada/ottawa/britannia-water-purification-plant-flood-1.5113635
