Storm drainage recovery and resiliency projects

Outfalls Repairs

After the June 2013 Flood, The City of Calgary inspected the Bow and Elbow Rivers and Fish, Nose and West Nose Creeks for significant damages to outfalls and riverbanks.

We identified 161 outfalls on the rivers and 53 outfalls on the creeks with damage and prioritized them for repairs.

About the projects

Repairs to outfalls include removing existing vegetation, grass and shrubs from the outfall. Replacement or repair of cracked concrete aprons.

Placement of bedding gravel and rip rap will be added to provide erosion protection for the outfall and the River or Creek. This also helps to reduce turbidity. The measurement of turbidity is a key test of water quality.
