The curriculum for Manitoba is currently undergoing development and no training is offered in the Province at this time.

Those wishing to become certified practitioners in Manitoba  may participate in the Onsite Wastewater Practitioner Training Program offered through either the Alberta Onsite Wastewater Management Association or the Saskatchewan Onsite Wastewater Management Association.

These chapters of the Western Canada Onsite Wastewater Management Association offer excellent industry training that is recognized and accepted by Manitoba Environment, Climate, and Parks. These training programs are recognized across Western Canada under the New West Partnership Agreement (formerly TILMA) and federally through the Agreement on Internal Trade.

For more information on training opportunities contact the MOWMA office.


The MOWMA 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.


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.
