In 2021, EPCOR completed a project which involved replacing the soil backfill around one of our underground transmission lines within the Rossdale Substation.
It has been identified that additional work is required to replace the soil backfill around this location. Due to the sensitive nature of the area, we will work with archaeology experts to monitor any ground excavations that occur on this project. The existing backfill material will be removed using both hand excavation and a hydrovac to the depth of 1.5 metres. Once the old backfill is removed, a new high thermal backfill material will be put in its place to ensure the cables do not overheat. This work is expected to start in October and take approximately one week to complete.
