Providence storm water and outfall project

Providence Storm Water and Outfall Project

About the project

The City of Calgary is building new stormwater infrastructure on the southwest edge of Calgary to accommodate new development in the area. The Providence Storm Trunk is a 3.6 kilometre system that will transport treated stormwater from the new community of Alpine Park to Fish Creek, servicing approximately 900 hectares of development. 

The project is part of the New Community Growth Strategy which includes the Providence ASP Lands. Most of the work will occur within the Transportation Utility Corridor (TUC) which is an undeveloped section of land designated for infrastructure and utilities. By working within the TUC, we reduce the impact to residents and traffic in the area. 

Construction is taking place in three stages and began in June 2022 with completion of stage 2 in fall of 2024. The first stage constructs the trunk from 146 Ave S.W. just west of Stoney Trail north to Fish Creek Park. The second stage constructs the trunk from 154 Ave S.W. to 162 Ave S.W. Details of the third stage are pending and are dependent on planned future development. 

We have been working with citizens, community groups, and stakeholders, so that all parties understand the scope of work required to complete this project.

Project status – December, 2024

Stage 2 construction, which took place south of Fish Creek to 162 Avenue S.W., is now complete and the storm trunk is now in operation. We will be finishing up some landscaping in the area in spring 2025. The preliminary design phase for the third stage is set to begin in 2025. However, the construction timeline will depend on development needs, and no definitive schedule has been established.

Thanks for your support and cooperation during construction of the second stage of this important infrastructure project.

Project benefits

  • The project is part of the New Community Growth Strategy enabling us to make our city an attractive place for people to want to live and make a great life. This project complements city-wide goals and objectives for growth and development.
  • Most of the work will occur within the Transportation Utility Corridor (TUC), which reduces the impact to residents and traffic in the area. 
  • We will be microtunnelling, which is essentially installing utilities via a underground tunnel to avoid traffic and greenspace disturbances, under 154 Avenue.
