These answers are general. For your situation, check the official sources listed below or ask a professional.
How often should a septic tank be pumped?
Household septic tanks are typically pumped every three to five years. The right interval depends on the tank size, the household and the system: ask a professional to inspect it.
Is a septic inspection required when selling a home?
It depends on the province and the municipality. Some municipalities run mandatory inspection programs, and many buyers or lenders ask for an inspection before closing.
Do I need a permit for a new septic system?
Yes, in every province: new systems and major repairs need a permit or a filing with the municipality or the health authority, usually after a site and soil assessment.
