Frequently Asked Questions
How often should the tank be pumped?▾
Every two years for a year-round home, every four for a seasonal one. That is the general rule in Quebec.
What is needed to install or replace a system?▾
A soil characterisation study, a compliant design and a municipal permit, before any excavation.
What damages a leaching field?▾
Wipes, grease, excess water, certain chemicals and vehicle traffic over it. Clogging is the most frequent cause of early replacement.
Does adding a bathroom change anything?▾
Yes, it can exceed the system's designed capacity. An assessment is needed before finalising plans.
What are the warning signs?▾
Odours, soggy ground over the field, slow drains throughout the house and unusually green grass in one spot.
Septic Systems in Quebec: what to know
A home not connected to municipal sewer treats its wastewater on site. Septic systems are governed by provincial regulation, and municipalities issue the permits.
Pumping
The general rule in Quebec: every two years for a year-round home, every four for a seasonal one. Skipping pump-outs eventually clogs the leaching field, whose replacement costs many times the pumping avoided.
Building or replacing
A new system requires a soil characterisation study, a compliant design and a municipal permit before work begins. A contractor who offers to dig without those steps exposes you to redoing everything.
What damages a system
Wipes, cooking grease, chemicals in quantity, and a poorly set water softener sending too much water through. The leaching field must also be kept free of vehicle traffic.
Warning signs
Odours, soggy ground over the field, slow drains throughout the house, unusually green grass in one spot. A problem caught early costs far less.
Licence
The contractor must hold a Régie du bâtiment du Québec licence, liability insurance and a CNESST clearance.
