Catch Basin Locator Map


The City of Ottawa has more than 100,000 catch basins to provide drainage to roadways and green spaces.

And now, there is an online map so you can see where catch basins are located to help keep them clear of debris.

Maintaining a clear catch basin is important to prevent flooding in the wintertime when snow begins to melt and in the spring and fall when leaves and litter can prevent rainfall from properly draining.

The map is available at

I highly encourage any residents planning a spring clean-up event in the community to peruse the map and consider double checking your catch basins! Thank you.
