If the temperature rises above zero degrees Celsius in a short period of time, flooding can occur. The City maintains drainage systems to reduce potential flooding conditions. City crews remove snow and ice from catch basins on roads and sidewalks to ensure melting snow drains when required. It is normal for water to pool around a catch basin in wet weather. Roads are designed to drain based on the sewer capacity. Roadside ditches are cleared at the outlet end of the ditch system to provide drainage for the spring melt.
Catch Basin Locator Map
The City of Ottawa has over 100,000 catch basins to provide drainage to our roadways and greenspaces. As a critical component of the city storm collection system, keeping catch basins clear of debris (leaves, ice, snow, etc.) is important. Find the location of your nearest catch basin using the interactive map and help keep our system operating effectively.
The catch basins depicted in this interactive map are derived from existing and collected engineering drawings for the City of Ottawa's Geographic Information System and are protected by copyright. The locations of this infrastructure information are approximate, and should not be used for construction purposes.
Report issues with catch basins on the road
It’s normal for water to pool around a catch basin in wet weather. Roads are designed to drain based on the sewer capacity. Please call 3-1-1 if the catch basin issue is related to a missing catch basin (drain cover).
You may create a service request to advise the City of a catch basin (drain cover) that is:
- Blocked (causing flooding on the road)
- Sunken or raised
For all emergency requests call 3-1-1. If this service is not available to you please call 613-580-2400. All other Service Requests will be triaged and addressed as operations allow.
