Who approves septic work around Saint-Jérôme?

Québec’s Q-2, r.22 regulation governs wastewater treatment for isolated residences. For residences of six bedrooms or fewer, or other qualifying buildings producing up to 3,240 litres/day, municipalities administer the authorization process; larger systems can require provincial authorization.

A municipal permit/certificate normally needs site characterization and plans prepared by an appropriately qualified professional. Confirm pumping/maintenance duties and any municipal program in addition to the provincial design rules.
