Sanitary Sewer Flushing
Residents are advised that vactor truck flushing of the sanitary and storm sewer system will begin Monday, June 5, 2023 and will occur until the end of September. During this time, there will be minor traffic impacts and, for public and staff safety, occasional night work to avoid high traffic volumes.
Vactor truck flushing is an important maintenance task that cleans the sewer systems by using a high-pressure hose reel and vacuum to remove silt, debris, and tree root intrusions. This improves the overall quality of the infrastructure and helps to extend its useful life.
This year, staff will be working in:
- Quadrant 2 from June 5 until July 21 – A section to the West of the Ganaraska River, between Jocelyn Street, Cavan Street, and Victoria Street down to Lake Ontario.
- Quadrant 3 from July 24 until September 29 – A section to the East of the Ganaraska River, between Molson Street, Rose Glen Road and down to Lake Ontario.
For a detailed look at the affected quadrants, view our quadrant map.
Residents in the affected quadrants are advised to ensure all floor drains and plumbing traps are filled with water and all toilet seats are in the down position. This will help minimize the chance of vactor flushing ‘blowback’. This is a discharge of air and water that typically identifies the incorrect installation of plumbing fixtures/plumbing venting, or plumbing ventilation obstructions. If ‘blowback’ occurs at your property please contact Works and Engineering immediately by email or phone at 905-885-8760, so it can be appropriately addressed.
During this work, staff will also be using an optic camera to assess the condition of our sewer systems. This will help staff prioritize future maintenance activities. Please note that during this assessment process municipal staff use their cell phones for data entry and GIS mapping.
