When you buy a property with a septic system you take on responsibility for it under BC's Sewerage System Regulation. A failed system can be costly to replace, so it is worth understanding before you commit.

Ask for the paperwork
- Any filing on record with the health authority
- The maintenance plan, if there is one
- Pump-out and inspection records
- Permits or records for additions, extra bedrooms or suites
Your realtor can request a filing search. A system with no filing is not automatically bad, but it needs a closer look.
Have the system inspected
A proper inspection finds the tank and field, opens the tank, checks condition and looks at setbacks to wells, water and boundaries. It also considers whether the system suits the size of the home.

Look at the load
Count the bedrooms and suites. A system sized for a three-bedroom home may struggle with a basement suite and a large household.
Use the findings
If the report shows problems, the cost of repair or replacement can be part of your price negotiation, or a reason to walk away if your contract allows.

Questions about this guide
Is a septic inspection the same as a home inspection?
Not usually. Ask exactly what each inspector includes. A septic inspection has a specific system scope, access requirements and report; arrange it early enough for your property condition deadline.
