Outfall repair program

Outfall Repair Program

About the program

The City’s Outfall Repair Program repairs aging and damaged outfalls that take stormwater from rainfall or snowmelt into Calgary’s rivers. There are more than 800 outfalls located across the city.

This work is beneficial because damaged outfalls can lead to storm drain backups during heavy rainfall events resulting in impacts to both public and private property and the safety of citizens.

A damaged outfall could also lead to riverbank erosion and cause damage to infrastructure like pathways, sidewalks, roads and private property, especially in the event of a flood.

 

Project Updates

October 2024

The repair work in 2024 will involve the remaining 12 locations along the Western Headworks Canal.

Construction will commence with outfalls IC19 and IC18 the first week of November, followed by IC17 and IC16 late November. Repair work for each outfall location will take two to three weeks to complete. 

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.
