This summer, EPCOR will perform maintenance on an underground transmission cable near the Rossdale Substation. Certain soil types can cause transmission cables to overheat and shorten their life expectancy. This project will involve changing the type of soil backfill around the cables to increase heat transfer, so the cables do not overheat and can operate at optimal levels.
To complete the work, we will excavate around the transmission cables located in the southwest corner of River Valley Road (95 Avenue) and 105 Street (shown in dark blue on the map). A hydrovac truck will be used to excavate five feet below the ground to remove the existing backfill material. Once the old backfill is removed, the new high thermal backfill material will be put in place. This work is scheduled to begin at the early September and will take approximately two days to complete.
Due to the sensitive nature of the area, we will work with archaeology experts to monitor any ground excavations that occur on this project.
During construction, you may notice temporary traffic disruptions to River Valley Road and 105 Street as equipment is brought in and out of the site. In addition:
• The multi-use trail south of River Valley Road will be closed. Pedestrians and cyclists will be detoured around the work area.
• Signage will be used to manage traffic and notify pedestrians/cyclists of any necessary detours.
• All affected landscaping, pavement, and sidewalks will be restored to their original condition. Restoration will take place between August and September, as weather permits.
