Nose Creek Sanitary Sewer Trunk

About the project

The Nose Creek Sanitary Sewer Trunk Project involved twinning the existing sanitary sewer trunk that runs from the Bow River, north beyond Beddington Trail N.E. This extension more than doubled the sanitary sewer capacity which is required to accommodate future development and population growth in north Calgary. 

Without this new infrastructure in place, forecasts suggested that the existing sanitary system would reach capacity in or around 2030.

The project  began in 2008, consisted of three phases of work and is now complete.  

Project benefits

  • This project was necessary for storm and wastewater management and accommodates projected population growth in north Calgary. 
  • Much of this project work was completed by tunnelling which reduced construction impacts on the park and green space. 
  • We  improved Laycock Park for all users, including completing missing pathway connections and constructing a new parking lot. In addition, a rain garden was planted with low-maintenance water-wise plants that attract birds, butterflies and mosquito-eating dragonflies.

Construction timelines

  • Q1 2024 – Q2 2025: Sanitary sewer pipe tunnelling. Construction sites for tunnelling shafts were setup (A) south of Beddington Trail N.E. beside the Nose Creek Pathway, (B) in Laycock Park beside 64 Ave N.E., and (C) at the Beddington Trail N.E. and Deerfoot Trail interchange near Nose Creek.
  • Q3 2024 – Q3 2025: Laycock Park drainage improvements located within the park on both sides of Nose Creek. 
  • Q1 2025 – Q3 2025: Sanitary sewer pipe excavation at Beddington Trail N.E. and Deerfoot Trail, east of Deerfoot Trail. 
  • Q2 2025 – Q3 2025: Landscape restoration.
  • Q4 2025 – Q3 2028: Maintenance of infrastructure and landscaping.

Project timeline

Phase A - involved twinning the existing sanitary sewer trunk along Nose Creek from the Bow River to 32 Ave N.E. Construction work started in 2010 and was completed in 2013.

Phase B - involved twinning over 10km of sanitary pipe from 32 Ave N.E. past Beddington Trail N.E. Construction started in 2014. Construction for the final segment of Phase B work  began in 2024 and involved the installation of 2.2km of 1650mm sanitary pipe from south of 64 Ave N.E. to north of Beddington Trail N.E. This work was completed in fall 2025.

Phase C - transferred into a new project: Saddle Ridge Sanitary Sewer Trunk Upgrade. This project added a relief sanitary sewer trunk connection to the Nose Creek sanitary sewer trunk from Fox Hollow Golf Course, under Deerfoot Trail, and into the sanitary system near 11 St N.E. and 12 St N.E., which services a large portion of northeast Calgary. The work was completed in 2017.
