Where do the CSOs take place?
There are 18 combined sewer overflow outfalls in the City of Ottawa that discharge to the Ottawa River and Rideau River. However, six of the outfalls account for more than 97 per cent of all overflows: the Rideau Canal, Booth, Keefer, Cathcart, Manor Park, and Cave Creek. All but Manor Park and Cave Creek are presently under reconstruction as part of the Real Time Control initiative (Project 1). This situation is limited to a well-defined area of the city. Communities constructed outside that area do not contribute to this problem.
