Ottawa’s $232-million combined sewage-storage tunnel unveiled Friday
Posted Nov 20, 2020 02:52:00 PM.
The City of Ottawa's combined sewage storage tunnel (CSST), designed to reduce sewage overflows into the Ottawa River, is ready to be put into operation.
The project is part of the Ottawa River Action Plan (ORAP), the city's roadmap to protect the Ottawa River for future generations.
The CSST, which can store up to 43,000 cubic metres of sewer overflow, will significantly reduce the frequency of sewage overflows into the river during storms.
Once a storm ends, the water will be treated and sent back into the Ottawa River.
Additional benefits of the project include:
- Reducing the risk of basement flooding for several low-lying lands in the Glebe/O'Connor area
- Increasing operational flexibility and redundancy to major collector sewers.
Ottawa Mayor Jim Watson, Ottawa Centre MP Catherine McKenna and MPP Lisa MacLeod will be on hand for the opening at 2 p.m. on Friday, November 20, at the CSST Site 1 Odour Control Facility at LeBreton Flats.

The $232.3-million dollar project included investments from all levels of government.
