Program Details
The Building Code Act, 1992 (BCA) and the Ontario Building Code (O. Reg. 163/24), regulate the design, construction and renovation of treatment systems which are located wholly on the property which they serve (i.e. “on‐site”) and have a design sewage capacity of 10,000 litres/day or less. Such systems typically provide treatment for smaller buildings such as houses, cottages, and small businesses.
The Building Code establishes and governs mandatory on‐site sewage system maintenance inspection programs, to be administered in certain areas by local enforcement bodies having jurisdiction. The Building Code also governs discretionary on‐site sewage system maintenance inspection programs established by local enforcement bodies.
Sewage system maintenance inspections are intended to determine whether a sewage system is in substantial compliance with the operation and maintenance requirements outlined in Division B, Section 8.9. of the Ontario Building Code.
Mandatory Inspections
The Ontario Building Code (O. Reg. 163/24), Division C, Subsection 1.10.2. - Mandatory (Sewage System) Maintenance Inspection Program prescribes that all sewage systems wholly or partly located within a vulnerable area that are located in a source protection area are required to be inspected every 5 years if they pose a significant drinking water threat under the Clean Water Act.
Mandatory Inspections were completed in 2025 and are scheduled for reinspection in 2030.
Discretionary Inspections
The Ontario Building Code allows for properties located outside of the Mandatory Inspection area to be subject to a Sewage System Maintenance Inspection Program.
The Township’s Discretionary Sewage System Maintenance Inspection Program applies to all properties abutting Township-identified waterbodies (Dummer/White Lake, Stony Lake, Clear Lake and Katchawanooka Lake).
The Township has been divided into 10 zones which is shown in Appendix A to By-law 2024-31, as amended. One or more zones will be selected for inspection every year. Property owners will receive an information package in the spring of their inspection year.
Any sewage system that is in a zone where the inspection program is actively taking place and was newly installed or fully replaced within the previous 10 years is exempt from the program.
Inspection Zones
A GIS Sewage System Maintenance Inspection tool has been created so that property owners can identify if their property is subject to either type of inspection, what zone the property is in, and it will show the properties which are to be inspected during the current year. The inspection year will be updated for the next zone at the end of the current year.
If your property is not part of the sewage system maintenance inspection program it will not be found in the GIS Sewage System Maintenance Inspection tool.
