This excludes systems which include an advanced treatment unit which can only be installed by a licensed installer.
It is the installer and applicant’s responsibility to contact the Ottawa Septic System Office to request inspections at appropriate stages of the project.
Note: Requests for inspection must be made in writing using prescribed request form via fax, email or in person.
Installation Inspection: (allow 3-5 working days)
Once the tank is installed with the components in place, but before it is covered by fill, an inspector must visit the site to verify tank size, separation distances and proper connection. To request an installation inspection, the following must be submitted in advance to the Ottawa Septic System Office:
• “As-Built” drawing and components
• Tank Receipt
Once the inspector has approved this stage, the tank can be covered and graded
Final grading Inspection: (allow 3-5 working days)
Prior to the final grading inspection and issuing of the Certificate of Completion, the following must be completed:
• The tank must be covered with backfill and topsoil which has been properly graded
• Conditions of the Sewage System Application must be met
• Electrical and alarms must be operational and ESA permit number is required (if applicable)
Note: It is required under the Ontario Building Code to have the lid on the outlet side of the tank to be at grade to allow for servicing to the effluent filter.
Once this inspection and the conditions are met, a Certificate of Completion will be issued. This certificate means the completed installation has been approved and the septic system can now be used. This document is required to obtain an occupancy permit of a dwelling. Some systems may require an additional maintenance contract agreement.
Note: As Built Drawings and Components are required to list the materials used in construction and identifies the installer on record. Drawings provide the actual measurements and cross references to the location of the system as constructed and verifies the installer has followed the purposed design from the approved application.
