EPCOR Drainage Service Ph: (780) 509-8080Email: epcordrainage@epcor.com
On October 12, a hole formed in the roadway at the intersection of 61 Avenue and 109 Street. The hole in the roadway is approximately 3 metres long, 1 metre wide and 23 metres deep. The hole formed as a result of an underground void which EPCOR discovered on October 8 during an inspection of a sewer trunk line.
There is no structural risk to homes and businesses in the area. Based on assessments so far, it appears the void area is limited to a section under 61 Avenue.
The sewer trunk line that runs under 61 Avenue is 1650mm in diameter and carries both storm and sanitary flows.
In order to further investigate and determine the extent of the damage and the scope of repairs we are installing a bypass system. Installing the bypass is complex due the depth and size of the sewer trunk line.
A bypass takes flows from the below ground drainage system, brings them above ground in a pipe to discharge the flow into a manhole away from the work area. Where the bypass crosses intersections, the pipe will be buried under the road to reduce traffic impacts. Bypasses are monitored 24 hours a day, 7 days a week, to ensure the safety of the public.
We are also constructing 3 shafts on 61 Avenue that will support the installation of the bypasses and provide safe access to the trunk line to begin a full assessment of the issue.
Residents may experience some increased sewer odours as a result of the bypass. The pumps for the bypass will generate continual, low decibel noise. There will also be general noise as construction equipment and trucks will be used for material delivery, excavation and soil removal. EPCOR will do everything possible to manage noise associated with the construction. Lights will also be on around the work site through the night to allow for adequate monitoring.

Prioritizing safety
Out of an abundance of caution and public safety, we have closed the intersection as we continue to investigate to determine the affected area and scope of the repairs. As a result, there are significant traffic impacts in the area as outlined on the map.
At this time we do not have a timeline on these road closures, however we do expect the intersection to be closed for several months. We ask that motorists take their time, follow signage and consider taking alternate routes if possible.
At this time we don't have firm timelines on how long the emergency repair will take. However, due to the complexity of the work we anticipate it will take several months to complete. More information on expected timelines will be provided once the repair plan is finalized.
We have ground monitoring in place and will be carefully watching for any changes at the surface.
The construction area in the intersection will continue to be fenced and marked as restricted areas. We will take every precaution to ensure public safety, and we request your assistance in keeping a safe distance from the construction site and the equipment.
EPCOR is closely monitoring the situation related to the COVID-19 outbreak. Protocols have been put in place for our employees while performing essential work to protect the health of our teams and our customers. We also request homeowners take precautionary measures by maintaining a safe, two meter distance from our crews.
