So I got back from helping Maple Creek recover from their recent flood and last night we had our basement get flooded out after our own storm of the century. Here is the PSA from the City of Saskatoon.
Overnight, Saskatoon received approximately 80mm (almost 3 inches) of rain in three hours. In some areas, it was more than 100mm (over 4 inches).
At this time, the initial assessment indicates that numerous locations throughout the city have experienced surface flooding. As of 6:00 a.m., the City had received 50-60 reports of flooding on streets and homes. Crews are responding to those flooded streets.
Storm water ponds on the west side filled past capacity. The new sewage storage superpipes were filled to capacity and then overflowed through manholes to the surface with the pressure. Combined these storage tanks have a capacity of 3.5 million liters of sewage. The system worked as it was intended, but was overwhelmed by the intensity of the rain.
Numerous power outages occurred as a result of the storm as well, but power has been restored to those neighborhoods. Saskatoon Fire & Protective Services responded to 45 storm-related calls, such as downed trees and power lines, cars stuck in flooded intersections, and alarm systems going off.
If your street remains flooded, or if you experienced sewage backup, call the City of Saskatoon at 975-2476. While the City is tracking what areas flooded, you will also need to call your insurance company to report a claim if your basement flooded.
As I was bailing water away from the house at 3:30 a.m. and hoping I would not be struck my lightning or a falling tree, I would guess we got close to the 4 inches of rain that the airport got. Of course this was on top of the record amount of rain that Saskatoon has already gotten this spring. From April 12 to June 28 we had 285mm of rain – or close to three times the normal amount.
Our basement wall actually sprung a leak which flowed like a fountain into our basement for a while. A look at the hole this morning showed some weakened cement in a small area which will need to be patched with hydraulic cement and I think I am going to get a sump pump installed. We had several inches of water in the basement last night but we have most of that soaked up and being dried out by fans now.
