Repairs and Maintenance

We operate and maintain the water and wastewater collection and distribution systems in Calgary.

We provide repairs and maintenance for more than 16,000 km of underground pipes for water, sanitary sewer and stormwater.


Construction Projects

We work on new construction projects to improve and expand our water and waste water systems and mitigate potential flooding issues in our storm water system.



Flood Recovery Projects

We have identified over 200 flood-related projects requiring repairs or restoration.

We are working on a number of Riverbank stabilization and erosion sites. We are also working on the storm drainage system and lift stations. To learn more, visit our Flood Mitigation and Recovery Projects page.


Stormwater Quality Retrofit Program

The Stormwater Quality Retrofit Program is adding more wet ponds to long-established areas of the city. Wet ponds protect the quality of water in our rivers by slowing the water down and allowing sediment to settle out. Plants in the wet ponds help remove pollutants.
