The City of Ottawa is responsible for maintaining its storm and combined sewer outfalls. Several outfalls to the Ottawa River between Shirley’s Bay and Petrie Island were constructed in the 1930’s to 1960’s. They are now nearing end of life and require rehabilitation.
Given the scope, complexity and permitting requirements to complete this project, replacement and/or rehabilitation of the various outfalls will take place in phases. Rehabilitation of the first three outfalls began in the summer of 2019, with final landscaping work to be completed in the spring of 2020. Rehabilitation works on the second phase of outfalls was undertaken in the summer and fall of 2020. The third phase is currently in design and construction is expected between 2021 and 2022.
The anticipated construction period for each of the outfalls is presented in the table below. For most of the outfalls, it is anticipated that construction work at each site will take less than 2 months to complete. For the more complex outfalls in the third phase of the project, construction may take upwards of 6 months to complete. The actual construction timing will be subject to final environmental approvals.
