The Alberta Onsite Wastewater Management Association provides excellent industry training program for Onsite Wastewater Practitioners and Professionals. The Onsite Wastewater Practitioner Training Program for industry certification is recognized in the Western Provinces through Alberta Municipal Affairs, the New West Partnership Agreement (formerly TILMA) and federally through the Agreement on Internal Trade.

As well as this industry certification program, the AOWMA offers individual field and classroom training sessions for continuing education purposes. For information on training opportunities in your area, contact the AOWMA office.

A list of available training opportunities, including course descriptions and registration is available through the AOWMA Store.


The AOWMA provides information to homeowners both on its website and through its Septic Sense public education program.  Homeowners can access information on building a new onsite wastewater (septic) system, repairing and maintaining an existing system, and best practices for system operation.

Work Camps & Drill Sites

The guidance document “Temporary Onsite Wastewater Treatment Systems at Work Camps” details acceptable site and soil evaluation criteria for temporary work camps and rig sites that recognizes the challenges of winter installation and short-term use. 


Each province provides a listing of those working in the onsite wastewater (private sewage, septic systems) registered with the program.  Information includes the region the person works in, their scope of work, contact information, and certification status.  A certification status of ‘yes’ means that the contractor and/or members in their company are trained and certified to provide the services listed under their scope of work.
