Having safe, reliable utility services is a critical part of day-today life in the community.
The existing Duggan sanitary tunnel provides service to neighbourhoods in southwest Edmonton and has been identified for replacement. This will see construction of a new sanitary tunnel to service neighbourhoods from Steinhauer up to Bonnie Doon.
The alignment of the new tunnel is along 111 Street from Saddleback Road/29A Avenue, east along 34 Avenue, and then north on 106 Street to north of L.Y. Cairns School.
EPCOR is aware of consistent sewer odour issues in several neighbourhoods along the alignment of the Duggan Tunnel, particularly in Steinhauer. This project is part of EPCOR’s Corrosion and Odour Reduction Strategy (CORe). The strategy aims to understand and mitigate sewer odour issues and will result in significantly reduced sewer odour city-wide by 2031. With completion of the new tunnel, we expect the major cause of how odour is formed and pushed out into the communities to be notably diminished.
The majority of the work will be underground using a tunnel boring machine (TBM). However, there will be multiple worksites (shaft locations) along the tunnel alignment to allow the TBM to be lowered underground to excavate, turn corners, and be removed when tunneling is complete.
While we try to minimize disruptions during our project work, there are some things that may affect you throughout the project, like traffic impacts and sidewalk closures.Impacts to you
As we complete construction for the Duggan Tunnel Replacement Project, you can expect to activity that's typical to construction. In addition to work activities needed for this project, like open trench excavation and micro-tunneling, here are some things to expect during construction. Construction impacts
Construction will begin in March 2023 with completion anticipated by the end of 2024.Timeline
