Blocked Sewer Connections

The Region will perform the following services for its sewer customers at no charge.

If the sanitary sewer connection is backing up, causing flooding inside your building:

  1. The Region provides a 24 hour cleaning service for sanitary sewer connections from the main sewer to the house for single family, semi-detached and street townhouses and linkhouses with separate direct connections to the sanitary sewer.
  2. A readily accessible 100 mm (4 inch) diameter cleanout must be available. If the cleanout is less than 100 mm or a "T", only one attempt at cleaning will be made.
  3. For Industrial and Commercial properties, the Region will only clean from the property line manhole or cleanout to the main sewer.
