Outfall repair program

Outfalls Repairs
Outfalls are exit points by which storm water leaves the pipe system and enters the river. There are more than 800 outfalls located across Calgary.
 

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.

February 2024

The WH Canal Outfall Repair Program will repair many of the aging and damaged outfalls along the Western Headworks Canal. The 35 outfalls along the canal were assessed and 15 outfalls have been prioritized for repairs over the next couple years.

The IC3, IC7 and IC8 outfalls, located on the east bank of the Western Headworks Canal will undergo repairs starting approximately the week of February 12, 2024. IC3 is located just south of the Max Bell Arena, while IC7 and IC8 are near 19 Ave SE and 26 St SE.

The repair of outfall IC12 will follow, beginning closer to the beginning of March, 2024.

Work at these outfalls will include reconnecting pipes that have separated over time, installing new riprap to reduce the water’s force before entering the canal and restoring any areas on the slope that get disturbed during construction.
