- Construction of a connection between the CSST North South Tunnel under Kent Street and the brand new McLeod Street combined sewer at Site 8. Implementation of an odor control facility located on Catherine Street at Site 9.
- Tunnel launch shaft construction is underway at Site 10. Tunneling along Kent Street is expected to begin in the summer of 2017 and continue for the remainder of the year. Construction of the shafts at Site 8 and odor control facility at Site 9 is expected to start in the spring of 2018, and continue for approximately 12 months.
The CSST will include the construction of two tunnels: an east-west tunnel (EWT) through the downtown core from Stanley Park to Le Breton Flats, and a north-south tunnel (NST) under Kent Street from Chamberlain Ave to the Supreme Court.
To complete this project, there will be several surface construction sites and underground tunneling operations within the downtown core.
Representatives from the City and the project team will be available to provide the information and answer your questions.
Many of the benefits of the CSST Project include:
- Greatly reducing the frequency of sewage overflows during storms from entering the Ottawa River
- Helping to protect the Ottawa River and reducing overflows from entering the river
- Reducing the risk of basement flooding for several low-lying lands in the Glebe/O’Connor area; and,
- Increasing operational flexibility and redundancy to major collector sewers
The environmental assessment for the CSST Project was completed in January 2013.
Overall CSST construction will continue at various sites throughout the City until the end of 2019, with the CSST becoming operational mid-2020.
