As part of its efforts to proactively maintain and assess the condition of the City’s wastewater collection lines, the Utilities Collections Division has a Cleaning and Inspection Program.
The length of time to inspect and clean a line depends on its length, the amount of debris and its structural condition.
Residents will be notified 3 to 7 days before routine cleaning and inspection is scheduled in their neighborhood. While the process will not affect most homes, the inspection and cleaning processes can create a vacuum effect that can pull the water out of household plumbing.
The Utilities Collections Division is systematically inspecting and cleaning the City’s wastewater collection system lines on a 3 to 5-year cycle. The system is divided into 3 basins (PDF).
