Fish Creek West Sanitary Trunk
Project Status – August 2023
Crews continue work on the south side of Anderson Road between Canyon Meadows Golf Course and the pedestrian bridge installing a new sanitary trunk. While crews are working between the pedestrian bridge and 24 Street S.W. the right eastbound lane will be closed to traffic.
Work on the north side of Canyon Meadows Drive S.W. continues between Canso Crescent and Canterbury Drive S.W as well as 6 Street and the Macleod Trail bridge. Work in this area includes installing a new traffic light at 6 Street S.W. for improved pedestrian safety in the area.
Residents may notice an increase in construction vehicle traffic in the Woodbine community. Most of the construction traffic is using Anderson Road and 24 Street S.W. but vehicles will have to use some residential streets in Woodbine until October 2023. We are making efforts to limit the amount of construction traffic in residential areas and you can see the routes here.
Crews have finished the work have completed the microtunneling work east of the CP/LRT tracks. Residents will see equipment in the area over the next month, and there is also additional construction we will be doing over the summer close to Cantrell Drive S.W.
Traffic detours & lane closures:
- On September 2, 2023 The Canyon Meadows and Canterbury, and the Canyon Meadows and Elbow Drive S.W. intersections will be closed for access to Canyon Meadows Drive S.W.
- Canyon Meadows westbound lanes are closed to traffic between 6 Street and Canterbury Drive S.W. There is one lane of east and westbound traffic on the eastbound lanes.
- The Canterbury Drive S.W. intersection will have no access to Canyon Meadows Drive from Canterbury Drive S.W. Detour signs will be in place for residents.
- On Canyon Meadows from the Macleod Trail bridge to Canterbury Drive S.W. both westbound lanes will be closed. One lane of east and westbound traffic will be maintained on the eastbound lanes.
- September 5 to 27, 2023 Woodbrook Way S.W. will be closed to traffic. There will be no on street parking while crews are working in the area, and pedestrian detours will be in place.
- While crews are working there will temporarily be no parking on the north side of Woodglen Way, Woodbrook Way and Woodford Crescent S.W.
Odour control building
As part of the design for the sanitary trunk system, The City conducted studies and modelling which showed the siphon and surrounding area was susceptible to odour migration. To reduce the migration of odours in the area The City will be building an odor control building near the LRT/CP tracks at 490 Canyon Meadows Drive S.W.
A scrubber odour control unit will be mounted inside the building and is designed to remove vapours and sewage odours from the sanitary sewage collection system. The scrubber odour control unit removes odours and vapours by capturing and neutralizing odour molecules. Please see the frequently asked questions for more information on this building. Once construction of the building is finished, we will also be landscaping the area. You can see the landscape plan here.
About the project
The Fish Creek West Sanitary Trunk will transport sanitary flows (wastewater ) from the communities of Woodbine, Woodland, and Canyon Meadows, as well as, wastewater from Tsuut’ina Nation. This wastewater will travel through Calgary’s wastewater collection system to the Fish Creek Wastewater Treatment Plant
In response to projected growth and development in the area, hydraulic modelling, conducted in 2020, resulted in the recommendation to increase the capacity of wastewater infrastructure to a 1:50 year service level. This improvement will:
- Mitigate risk of wastewater surcharge (and subsequent property and environmental damage) due to projected increased flows;
- Support development in south-west Calgary and Tsuut’ina Nation
- And lastly, in partnership with Tsuut’ina Nation, H2S will be better managed and monitored.
Construction starts in September 2022, and we anticipate it will be complete in November 2023.

Additional alignment information
- The sanitary pipe alignment extends 6.3 kilometers, along existing Road and Utility Rights of Way.
- This alignment was approved as it minimized impact to interested parties:
- Do not need to cross (excavate) Canyon Meadows Golf Course
- No construction needed on Tsuut’ina lands and no crossing of Tsuut’ina Trail required
- No disruption to private property/residences
Further, to minimize traffic impact in the area, approximately 50 per cent of installation will occur on grass berm or boulevard areas.
- Design: Spring – Fall 2021 (Complete)
- Construction start: Fall 2022
- Construction completion: Fall 2023
Frequently asked questions
Due to current and projected growth in the area, quite simply, there will be more wastewater (sewage) than the existing infrastructure can accommodate. We need to do this work to accommodate projected wastewater flows.
No. As with all City of Calgary projects, careful consideration of the natural environment will be of utmost importance, as will adherence to all environmental standards and regulations. Alignment of this trunk has been designed to run along the existing Road and Utility Rights-of-Way,. which are primarily designated for roads and/or replacing, repairing or upgrading utility infrastructure.
Removing tree is always a last resort. However, tree removal is necessary to complete this important infrastructure upgrade to your community.
In addition to tree removal, shrubbery will need to be removed. The City will replace the trees as appropriate upon project completion.
Tree compensation is based on the value of the impacted trees, which is determined by considering the health, size, species and location of the tree using standard international methods. Replacement trees are planted in the closest suitable location to replace the impacted trees.
The City works closely with our regional customers regarding water and wastewater Master Servicing Agreements.
- We continue to work with residents and interested parties to ensure a clear understanding of the scope of work required.
- We have consulted with Tsuut’ina Nation on various matters relating to this project.
- We commit to providing timely project updates as we complete this important work for Calgarians.
