Ottawa is on the verge on completing and activating it's new Combined Sewage Storage Tunnels (CSST). One tunnel runs along Kent from Chamberlain (south of the Queensway) to Parliament Hill, the other from LeBreton Flats, next to the Confederation Line west tunnel portal, to Stanley Park in New New Edinburgh. The $232 million project can store more than 43 million litres of sewage. This 6.2 kilometre network of tunnels will prevent billions of litres per year of raw sewage from spilling into the Ottawa River. The tunnels pass under the Confderation Line at two points.
The tunnels will store raw sewage during heavy rainfalls and transport them to the Robert Pickard sewage treatment facility before dumping the treated water back into the Ottawa River.

Interesting. When I lived there, heavy thunderstorms would often result in discharges into the Ottawa River.
Glad to see they've developed a solution. I'm not in the city anymore, but does the combined sewer system extend much beyond downtown, or does it extend to the limits of these two sewers?
