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 project was necessary for storm and wastewater management and accommodates projected 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 extension more than doubled the sanitary sewer capacity which is required to accommodate future development and 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.
Did you know?
- A part of Phase B of this project (Contract 4) has the world record for the longest continuous, curved microtunnelling drive, with 1650 mm diameter pipe covering a distance of 1.5 km!
- This project won or was nominated for several industry awards, including the 2025 No-Dig North Project of the Year for Canada – New Installation.
Project timeline
Phase A, completed 2013. Involved twinning the existing sanitary sewer trunk along Nose Creek from the Bow River to 32 Ave N.E.
Phase B, completed 2025. Involved twinning over 10km of sanitary pipe from 32 Ave N.E. past Beddington Trail N.E. 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.
Phase C, completed 2017. 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.
