Saddle Ridge sanitary sewer upgrades

The Saddle Ridge Sanitary Sewer Upgrades project will provide sanitary servicing to northeast Calgary. With current approved development plans the servicing area is expected to increase 1,800 hectares by 2035. In order to maintain the level of service within the sanitary system and provide additional capacity to support future developments, the sanitary sewer system will be twinned.

Project summary

The project is located south of 32 Avenue NE on Deerfoot Trail. The alignment of the sewer will start directly east of Deerfoot Trail at the Fox Hollow pedestrian bridge then cross Deerfoot Trail, finishing at a tie-in point in the Fox Hollow golf course. The sewer will be installed using trenchless tunneling under Deerfoot and open cut through the golf course. There are no anticipated disruptions to traffic on Deerfoot. Please see the latest project notice for more information.

During design, consultation with the Fox Hollow golf course took place so that the design would minimize the impact on the golf course.


Construction is expected to take place between June and the end of September this year.

Project impacts:

  • Additional noise and dust (will be controlled by contractor)
  • Due to trenchless tunneling methodology, 24 hour a day work may be required to protect tunneling equipment
  • An area of the golf course will be fenced off for construction – we are working with them to minimize impacts

Please note: The length of construction can vary depending on the location of the work, condition of the soil, the condition of existing utilities, seasonal activities, availability of materials and difficulty and location of the excavation.
