Fish Creek West Sanitary Trunk

Project Status – January 2023

Work to resume in January

Crews will be back for the micro tunnelling work on 14 Street S.W. January 23. Crews are also working on the south side of Anderson Road between 24 Street and 14 Street S.W. to install a new sanitary trunk over the winter months.

Crews will be working on January 24 and 25, 2023 to complete underground investigation work for the Fish Creek Sanitary Upgrades underway. Crews will be working in the utility right of way north of Woodbrook Way S.W. during this time and residents can expect some increased noise while this work is completed. 

Active work areas: 

  • Canyon Meadows Drive from Canso Crescent to 14 Street S.W.
  • Anderson Road between 24 Street and 14 Street S.W. 

Traffic detours & lane closures:

  • Westbound Canyon Meadows Drive S.W. traffic at 14 Street has been shifted to a temporary roadway to northbound 14 Street S.W. Southbound 14 Street S.W. traffic has been shifted to the westbound Canyon Meadows Drive S.W. lanes. 

Where crews will be working in 2023:

  • 14 Street S.W. micro tunnelling: January to March 2023.
  • Connection of the new sanitary line on 14 Street S.W. will start spring of 2023.
  • Anderson Road, west of Woodpark Boulevard S.W. will start spring of 2023.
  • Anderson Road, west of 24 Street to Stoney Trail S.W. will begin in May 2023.
  • Canyon Meadows from Canso Crescent to 6 Street S.W. work will start in May 2023.

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. 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.

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.
