The Mississippi Valley and Rideau Valley Conservation Authorities administer Part 8 (Sewage systems approvals) of the Ontario Building Code on behalf of several watershed municipalities (listed below). This means your local conservation authority is responsible for reviewing septic designs and plans, issuing Building Permits for new and replacement sewage systems, and inspecting installations to ensure compliance with provincial regulations.
Learn more on how to submit your application by choosing the municipality where you are installing or replacing a Part 8 sewage system. Not listed below? Check with municipality to learn about their septic approvals agent.
