Qualified Persons and Installers

Design and Selection by Qualified Persons

In many areas of Nova Scotia, wastewater from a home or business is treated and disposed of by means of an on-site sewage disposal system.

Qualified Persons can select an on-site sewage disposal system for residential use from the Standard. Professional engineers can design an on-site sewage disposal system from engineering design principles.

A notification must be submitted to, or an approval obtained, from Nova Scotia Environment prior to the installation of an on-site sewage disposal system. A notification and application for approval must be submitted by a qualified person or professional engineer.

Search for Professional engineers (formerly QPI), Qualified Persons (formerly QPII), septic tank cleaners, or an On-site Installer.

Installers are required to hold a On-site sewage system Installer’s Certificate of Qualification in order to construct or modify an on-site sewage system.
