Storm drains are a part of Calgary's stormwater system. There are about 60,000 storm drains in Calgary working to capture water and melting snow off sidewalks, streets and roads. If it's safe and possible to do, remove debris or snow blocking the drain. Create a channel, if need be, to help water flow.
Pooled water on your street
In communities built after 1990, The City installs devices in the storm drain to control how fast water flows into the system. During and after a rainfall event, these devices allow water to pool on the road (usually in a depression or low spot, called a trap low), until the stormwater system can accept the extra water.
Take a picture
If the storm drain remains submerged for more than 90 minutes or you cannot safely clear ice and snow away, take a photo and submit it via the 311 App or a web request. Attaching a photo goes a long way in helping our crews respond on a priority basis.
