Pumphouse Theatre - outfall repair and infrastructure upgrade

After the June 2013 Flood, The City of Calgary inspected the Bow River, Elbow River, Fish Creek, Nose Creek and West Nose Creek for significant damage to outfalls and riverbanks. We identified 161 outfalls along the rivers and 53 outfalls along the creeks with damage, and have prioritized them for repairs.

About the project

The June 2013 flood event damaged outfall B69, located on the Bow River directly north of the Pumphouse Theatre building, and the existing intake structure which consists of two concrete ducts in the river and a large concrete chamber set in the bank. Removal of the intake structure andrehabilitation of the outfall will occur between July 1, 2016 and April 30, 2017, or when The City’s Water Act Application is approved.

Construction activities associated with the project will include rerouting the storm piping and repairing the outfall, removing debris from river, demolishing and removing the old concrete water intake structure and stabilizing the riverbank. The removal of the intake structure will be conducted with the use of heavy equipment and divers.

This project will require additional rehabilitation following one year of the water intake structure being removed to allow river gravels to naturally fill in a large scour hole in the Bow River downstream of the concrete ducts.

Construction Impacts

Water Services is coordinating this work with Pumphouse Theatre, Parks, Pathways, Roads (Crowchild Trail Bridge Project) and Calgary Special Events. We are also working with our contractor, North Star Contracting, to mitigate construction impacts as much as possible which will include a pathway detour.

  • Construction fencing will be in place for the duration of this project.
  • Access to the construction site will be from Pumphouse Road S.W.
  • Construction vehicles, equipment and a small lay-down area for supplies will occupy the maintained Parks space north of Pumphouse Theatre and the maintained City of Calgary snow dump site to the east. Both areas will be fenced off for construction access only.
  • Work will be performed from 7 a.m. until 7 p.m. for approximately three months.
  • The temporary staging area and access route will be restored to original condition
  • There will be a pathway detour around the Pumphouse Theatre.
