Most of the time, water quality in the Ottawa River is great for recreational activities. However, that is not always the case.
When it rains or when snow melts, untreated sewage often flows in the river from combined sewers. These can pose a risk to public health, however the public are not informed of these overflows in real-time.
The City of Ottawa is currently working on Combined Sewer Storage Tunnels (CSST) to further reduce the amount of untreated sewage flowing into the river.
How Are We Helping?
Ottawa Riverkeeper has spearheaded a letter-writing campaign, encouraging people from Ottawa and Gatineau to ask their mayors for real-time reporting of sewage overflows. We have also worked closely with both cities to research solutions to real-time reporting, released a comprehensive report on report on water quality in the Ottawa River, and conducted numerous media interviews to spread awareness on the issue.
While we have seen some promising progress on this file, we will continue to work on it to increase transparency and ultimately end these overflows.
If you’d like to take action to address this problem, our new CSO Toolkit can provide you with the means to do so in your community!
We deserve to know when our water isn’t safe and which areas we should avoid at certain times. (You can read our report on water quality in the river here).
