Two tunnels designed to keep sewage from spilling into the Ottawa River have malfunctioned and caused a small spill, less than a year after they went into service.
The tunnels, with a price tag of $232 million, were opened last year on Nov. 20. They were part of the city's 2010 plan to keep surface runoff and wastewater from flowing untreated into the Ottawa River during very wet weather.
