Barrie, ON onsite wastewater guide

Septic systems in Barrie: permits, records, inspections and property checks

The City of Barrie publishes a one-page quick-start guide for constructing or altering a septic system. For onsite systems under 10,000 litres/day, the municipal Service Barrie counter handles building-permit applications through the APLI customer portal and gives a contact for unsafe sewage system conditions. The municipal guide says proposed new construction or alterations require a building permit, identifies Schedule 1 designer and Schedule 2 installer information forms, and distinguishes larger systems requiring provincial environmental involvement.

First, confirm this property’s wastewater service

Confirm the lot’s actual sewer connection and filing history. A municipal/health process is not proof that a particular septic system is approved.

For a Barrie property with an onsite system below 10,000 litres/day, submit the City onsite sewage permit through APLI and obtain inspection requirements from Service Barrie (705-739-4242).

Who approves septic work around Barrie?

Ontario regulates most residential onsite sewage systems under Part 8 of the Building Code. Systems with a daily design flow of 10,000 litres or less are generally administered by a municipality, health unit or conservation authority; larger systems fall under the environmental approval regime.

Confirm the exact Part 8 authority before applying. New systems, replacements, major repairs, additions or changes that increase design flow can require permit review, site/soil information, design calculations and inspections before covering.
