Under Alberta's Safety Codes Act and Permit Regulation, you must be certified by Alberta Municipal Affairs (AMA) to obtain a permit to install a private sewage disposal system. Holders of PS certificates can obtain permits for the installation of all types of private sewage disposal systems. Holders of PSR Certificates can obtain permits only for the installation of holding tank type systems.

What You Need

Certification by Alberta Municipal Affairs first requires successful completion of a six day training course offered by the Alberta Onsite Wastewater Management Association (AOWMA). Certification must be renewed yearly. For official, detailed information about certification requirements, see the Private Sewage webpage on the Alberta Municipal Affairs website.

Working in Alberta

Private sewage system installers who are certified and in good standing with a regulatory organization elsewhere in Canada may challenge a jurisprudence exam to be certified in Alberta if private sewage system installers in the two jurisdictions have similar responsibilities and competencies. For more information, see "What if I am already certified in another province or territory?" and the Alberta regulatory authority (below).
