Who approves septic work around Saint John?

New Brunswick’s provincial on-site sewage program is the regulatory anchor. Where municipal sewer is unavailable, building-permit packages may require proof of provincial approval before the local permit can proceed.

Confirm who holds the onsite sewage approval, whether a provincial certificate/approval is required for the proposed work, and whether the municipality needs that approval before issuing a building or development permit.
