New Brunswick: use Technical Inspections for onsite approval

The provincial Technical Inspections Services branch reviews on-site sewage applications; a municipal construction approval does not replace that process.

Regulatory starting point

Public Health Act — On-site Sewage Disposal System Regulation, 2009-137

The provincial Technical Inspections Services branch reviews on-site sewage applications; a municipal construction approval does not replace that process.

The application route

New Brunswick’s on-site sewage page points owners to the Department of Justice and Public Safety’s Technical Inspections Services. Installation, construction, repair and replacement require approval through the provincial process. An inspector assesses the application against Regulation 2009-137 and the provincial Technical Guidelines. Confirm any different treatment for a minor repair with Technical Inspections before work.

Site evidence and licensed work

The provincial online application refers to test pits and licensed installer information. Ask the installer and inspector what site evaluation, well/waterbody locations, plans and inspection before covering are required for the specific system. A municipal building permit, subdivision approval or sewer connection decision addresses a different part of the project.

Records first

Ask the provincial inspection service for the onsite application and inspection record; check municipal servicing or building files separately. If a city link below is only a general municipal homepage, it should help confirm sewer status rather than imply that city hall issues the septic authorization.

New Brunswick says a licensed installer applies for approval and a provincial inspector evaluates the application. After installation, the system must remain available for inspection and approval before it is covered. Ask for both the approved application and the inspection result when assembling a property file.
