CSST Schedule Update - August 2019

The City of Ottawa has provided an update for the Combined Sewage Storage Tunnel (CSST) project. The CSST is designed to reduce the frequency of combined sewage outflows to the Ottawa River, and reduce basement flooding risks for several neighbourhoods, while improving the flexibility and redundancy of major downtown collector sewers, specifically the 50-year-old Interceptor Outfall Sewer and the 80-year-old Rideau Canal Interceptor Sewer.

The CSST project continues has good progress with tunnelling towards Lebreton Flats which should be finished mid-November 2019. Here is the updated construction schedule.

Like the residents of New Edinburgh, we're looking forward to the end of construction so that we can move onto the rehabilitation and re-imagining of Stanley Park. 

If you have specific concerns about the construction project and its impact on our community, please contact 613-580-2424 x 22778 (2CSST) or email [email protected].
