Fish Creek West Sanitary Trunk

Project Status – November 2023

Anderson Road

Crews continue work on the south side of Anderson Road between Woodpark Boulevard SW and the Tsuut’ina Trail ramp for landscaping restoration.

Canyon Meadows

Crews are working installing pipe and constructing an odour control building on Canyon Meadows between Cantrell Drive SW and Macleod Trail. 

Upcoming construction timelines

Canyon Meadows

  • Construction of the odour control building at 374 Cantrell DR SW from October to December 2023.
  • Landscaping restoration at odour control building will start in Spring 2024.

South side of Anderson Road

  • Landscaping along Anderson Road from 14th Street to Stoney Trail.
  • A new maintenance path will be paved along this berm in Spring 2024, with an expected completion date of July 1, 2024. More information will be available closer to construction start date in Spring 2024.

Construction impacts

  • Certain areas on the berm adjacent to the south side of Anderson Road are currently fenced off to support landscape restoration. These barriers will remain in place through the winter months to keep the site secure and the public safe.
  • Residents will notice an increase in noise while this work is underway.
  • Pathway detour between pedestrian bridge and Tsuut’ina Trail ramp will be in place until mid-November 2023.
  • Construction hours are 7 a.m. to 8 p.m. Monday to Friday, 7 a.m. to 8 p.m. on Saturday, and 8 a.m. to 6 p.m. on Sunday.
  • Residents might notice diesel odours where crews are working with large equipment.
  • Residents are reminded to watch for detour signs, and please obey all temporary speed limit reductions that may be in place as per Alberta Traffic Safety Act.
  • Crews and any construction material will be separated from private fences by at least one metre.
  • Crews will be using natural gas generators during construction of the odour control building.
  • The contractor will take steps to limit the amount of dust in the work area.
  • Residents may notice, an increase in vibrations while crews are working, but we do not anticipate any impacts to private property.

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. 

Project map

There is a natural wave adjacent to the gravel bar which has been used for recreation such as river surfing.

  • This wave has been decreasing as natural sediment movement continues to occur and the gravel bar increases in size.
  • The area is hazardous for river rafters and floaters since they need to navigate around the gravel bar and can get stuck on the boulders where the river turns after the bridge.
  • Realigning the gravel bar would result in safer navigation for river users.

The project team is exploring incorporating a permanent recreational wave as part of this project. We are working with the Alberta River Surfing Association and the Alberta Whitewater Association who provide expertise and represent river recreation user groups.

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.

Project timeline

  • Design: Spring – Fall 2021 (Complete)
  • Construction start: Fall 2022
  • Construction completion: Fall 2023

Frequently asked questions

Why is this project required?

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. 

Will this impact Fish Creek Park?

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.

Are you removing trees?

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.

Have you done any consultation?

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. 

What about the proposed off-leash multi-use area in Woodbine?
