North Calgary Water Servicing Project

FLOWING FORWARD: SUSTAINABLE WATER INFRASTRUCTURE FOR THE FUTURE. North Calgary Water Servicing

The North Calgary Water Servicing Project (NCWS) involves the construction of a new 22 kilometre long water feeder main and multiple support facilities. The feeder main and facilities will deliver 100 million litres (ML) per day of clean, safe and reliable drinking water to existing and future communities in northwest Calgary, with long-term flows reaching 410 ML per day. The project is essential in providing adequate water supply for current and future population growth in the northwest area of the city.

The project is currently in the design phase, with construction of the feeder main and some facilities set to begin in 2025. As part of this project, a 6.5-kilometre section of the feeder main, along with upgrades to the Mountain View Pump Station will add an initial 30 ML per day to the City’s water distribution system. This work is anticipated to be completed by early 2027 and the entire system is expected to be in service by late 2029.

The North Calgary Water Servicing feeder main will run north from the Bearspaw Water Treatment Plant near Stoney Trail and Nose Hill Drive, crossing under Crowchild Trail up to 144 Ave N.W. and then connecting to the Northridge Feeder Main at 144 Ave and 14 Street N.W. The nine support facilities span throughout the length of the feeder main.

Project benefits

  • This project is essential to meet water demand in northwest Calgary given recent population growth and provides adequate water supply for future residential and commercial development to take place.
  • The new feeder main and facilities will increase redundancy in Calgary's water distribution system. This is an important investment as it allows us to continue to provide water service to Calgarians and customers when our existing feeder mains or pump stations are out of service in the event of emergency or planned repairs.
  • Specific sections of this project work will be completed by microtunnelling, which reduces construction impacts on traffic, parks and greenspace. This work will primarily take place under Crowchild Trail, across West Nose Creek, and a portion of 12 Mile Coulee Road. 

Project timeline

  • Phase A - Conceptual design of the linear section was completed in late 2023. Conceptual design of the facilities work will be completed at the end of 2025.
  • Phase B - Preliminary design work of the feeder main commenced in early 2024 and was completed in late December 2024. Survey work and geotechnical drilling was also completed in 2024.
  • Phase C - Construction on the open cut and microtunnelled sections begin in 2025. Construction on the first facility begins in fall 2025. Construction on the feeder main is expected to be complete by the end of 2028, with facility construction and system commissioning finalized by the end of 2029, at which point the entire system will be in service.
