North Calgary Water Servicing Project
FLOWING FORWARD: SUSTAINABLE WATER INFRASTRUCTURE FOR THE FUTURE. North Calgary Water Servicing
Project status – October/November 2026
We continue to make progress installing the feeder main and working on the support facilities.
We have successfully installed a section of the feeder main classified as Contract C1 located along a section of Rocky Ridge Road N.W. and 144 Avenue N.W. Crews are now finishing landscaping and repaving the roads. View our project map to see additional details.
We are now preparing to install another six kilometres of the feeder main along 144 Ave. N.W. – in the centre median – eastward from 69 Street N.W. to just west of Sage Hill Drive N.W. This stage of work is classified as Contract C2. This work will take place in sequences beginning October 13 until about the middle of December before pausing for winter. Work resumes spring 2027 and will extend to winter. See the Construction and Impacts section below for additional details.
We are also making progress on facilities including upgrades to the Mountain View Pump Station, expansion of the Top Hill Reservoir, construction of the new Pump Station at the Bearspaw Water Treatment Plant, and a new facility at the Big Hill Reservoir.
The North Calgary Water Servicing Project (NCWS) will construct a new 22 kilometre 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. Flows will reach 410 ML per day once a new water treatment plant is built. The project is essential in providing adequate water supply for future population growth in the northwest area of the city while adding redundancy to our water distribution system.
An initial 7-kilometre section of the feeder main, connections to two existing facilities – The Top Hill Reservoir and the Big Hill East Reservoir – 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 feeder main will run west from the Bearspaw Water Treatment Plant near Stoney Trail and Nose Hill Drive, turn north along 12 Mile Coulee Road N.W. crossing under Crowchild Trail. It will continue along Rocky Ridge Road N.W. up to 144 Ave N.W. It then runs east, connecting to the Northridge Feeder Main at 144 Ave N.W. and 14th Street N.W. The 10 support facilities span throughout the length of the feeder main.
The project involves seven linear (feeder main pipe) contracts and ten facility work packages which includes a pump station, reservoirs and control booster stations.
This project is one of several others which helps increase Calgary’s water transmission capacity which includes:
- South Calgary Watering Servicing Project (complete by 2031)
- Bearspaw South Feeder Main Improvements Project
- New water treatment plant at Bearspaw
- Crosstie Feeder Main (complete in 2029).
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.
- Sections of the project will be completed by trenchless methods (microtunnelling), which reduces construction impacts on traffic, parks and greenspace. This work will primarily take place under Crowchild Trail and a portion of 12 Mile Coulee Road.
Construction and impacts
Please note all work will take place from 7 a.m. to 10 p.m. weekdays and 9 a.m. to 10 p.m. weekends and holidays. Completed activities will be removed from the table.

Project timeline
Conceptual design
Conceptual design of the feeder main was completed in late 2023. Conceptual design of the facilities is in progress and will be completed in 2026.
Preliminary design
Preliminary design of the feeder main was completed in late December 2024 and is in progress on some of the facilities.
Construction
Construction on the first open cut section of the feeder main began in November 2025. Construction on the first trenchless section and the first facility began in fall 2025. Construction of 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.

Frequently asked questions
Why is the North Calgary Water Servicing project needed?
This project is essential to meet water demand in northwest Calgary given projected population growth and will provide adequate water supply for future residential and commercial development to take place, while adding redundancy to our existing water distribution system.
How much water will the NCWS project deliver?
This feeder main will deliver 100 million litres (ML) per day of clean, safe and reliable drinking water to existing and future communities in North and Northwest Calgary, with future flows reaching 410 ML per day after construction of a new water treatment plant.
Will capacity be increased before the entire project is complete in 2029?
Yes. As part of this project, a 7-kilometre section of the feeder main, along with upgrades to the Mountain View Pump Station will add an initial 30 million litres (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.
What is the route of the feeder main?
The feeder main will run west from the Bearspaw Water Treatment Plant near Stoney Trail and Nose Hill Drive, turn north along 12 Mile Coulee Road N.W. crossing under Crowchild Trail. It will continue along Rocky Ridge Road N.W. up to 144 Ave N.W. It then runs east, connecting to the Northridge Feeder Main at 144 Ave N.W. and 14th Street N.W. The 10 support facilities span throughout the length of the feeder main.
What type of material is the feeder main made of?
We factor in conditions in the ground along with the internal pressures the pipe will be subject to which has lead us to choosing steel as the most appropriate material.
