The City will replace the 100-year old cast iron watermain along Rowanwood Avenue, Thornwood Road, Chestnut Park and Roxborough Street with a newer, larger diameter watermain. This will improve the reliability of water supply to the neighbourhood.
Construction is expected to begin in spring 2025 and will take approximately 20 months to complete. The work will involve underground tunneling and open cut construction within the City right-of-way.
In August 2024, the City of Toronto notified residents of plans to replace the existing transmission watermain on Rowanwood Avenue from Macpherson Avenue to Wrentham Place.
Due to supply chain issues with specialized construction materials, this work will be deferred until spring 2025.
An update notice will be provided before work is to take place again.
A virtual Public Information Event was held on July 11, 2022.
The City is planning to replace the existing 900mm watermains on Rowanwood Avenue, Cluny Drive, Chestnut Park, Roxborough Street East, and Wrentham Place with larger 1200mm watermain to ensure sufficient water supply to residents.
Construction will involve both excavation of trenches (‘open cut’) and underground tunneling work for about 20 months.
Tunneling on Rowanwood Avenue will be carried out through two underground shafts (vertical tunnels). A tunnel boring machine (TBM) will excavate and construct the new watermain between the two shafts. One shaft at MacPherson Avenue, west of Yonge Street and the other shaft at Thornwood Road.
Open cut construction will take place on Thornwood Road at Chestnut Park and Rowanwood Avenue; Roxborough Street at Wrentham Place and Chestnut Park.
