Unprecedented no longer seems like an accurate word to describe the extreme weather Edmonton has faced this year.
To put it into perspective: Edmonton’s average rainfall for the entire summer season (June 1 – August 31) is 220.5mm. The previous record high for that period was 394.7mm in 1988.
So far this year, as of July 20th, we have seen 451.1mm of precipitation. That is more than double our average seasonal rainfall, and we are only halfway through the season.
While Edmonton’s stormwater infrastructure is built to handle significant weather events and normally operates far below capacity, this summer’s relentless storms exceeded the capacity that these systems are built for. These historic volumes are the main driver behind the sewer capacity issues and flooding we’ve seen. Additionally, EPCOR is less than halfway through a 20-year flood mitigation strategy – the Stormwater Integrated Resource Plan – which when completed will add to the system’s capacity.
During this period and as we continue through repairs, I have been in contact with EPCOR for updates to ensure that your needs are at the forefront of their remediation efforts. They are currently operating in a triage system that prioritizes public safety first as they work through repairs.
If you have experienced basement flooding and have not already reported it to EPCOR, please do so by calling 780-412-4500. Please also review their resources for before, during, and after a flood occurs. In addition, as I continue to stay in direct contact with them, feel free to share any outstanding questions you have with me.
I understand that it is frustrating and stressful. Many have had their personal properties impacted by this, and I know that it is concerning when we see streets overflowing and some locations with sinkholes emerging.
Update on Lauderdale Sinkholes
Following heavy rainfall, EPCOR responded to reports of roadway damage in Lauderdale. They identified the source as damage to the underground wastewater collection infrastructure between 130 Avenue and 107 Street. Epcor continues to monitor and keep the site secure to ensure public safety and is closely monitoring the area.
Emergency work is currently underway to construct an access shaft and install a temporary 24-hour bypass pumping system between 129 Avenue and 131A Avenue to keep services running uninterrupted while repairs take place.
-
130 Avenue is closed between 107 Street and 108 Street.
-
129 Avenue is also closed between 109 and 112 Streets for unrelated pavement repairs.
-
While these repairs are taking place, you can expect to see above-ground pipes, hoses, construction noises, and the possibility of slightly lower water pressure than normal.
-
Drinking water remains 100 percent clean and safe to use.
Please be mindful of all posted signage, stay clear of equipment and the bypass setup,
and keep a safe distance from fenced and barricaded areas.
I want to extend a sincere thank you to everyone for your ongoing patience as crews work diligently to complete the necessary repairs. It has been heartening to hear numerous stories of neighbours helping neighbours, along with deep appreciation for the crews working around the clock to restore normalcy. The Northwest is incredibly resilient, and we truly look out for one another.
