Mandatory Sewage System Maintenance Inspection Program

The Mandatory Maintenance Sewage System Program is intended to support the Ontario Building Codes health & safety‎ and environmental integrity objectives. The requirement for mandatory assessments was a result of recommendations brought forth from the Walkerton Inquiry and the objectives of The Clean Water Act.

The program requires the assessment of sewage systems on properties located immediately adjacent to the vulnerable zone of the Surface Water Intake area and properties located within the identified vulnerable area of a Municipal Wellhead. 

Section 8.9 of the Ontario Building Code (Operation and Maintenance‎) requires that all on-site sewage systems be operated and maintained in accordance with the basis on which their construction was approved. Thus, the mandatory maintenance inspection program is geared to identify systems that aren't being properly maintained and to provide education to home owners to ensure that on-site sewage systems do not cause a public health threat or environmental concerns.
