Who approves septic work around St. John’s?

For unserviced properties, provincial approval is central to private septic-system siting and installation. Municipal building processes can also require proof of that provincial approval before a local permit or final occupancy step.

Confirm the provincial site-evaluation/design route and the municipality’s building/development requirements. Do not backfill or conceal work before the required inspection/approval stage.
