Introduction to On-Site Wastewater Systems

Note: this course was formerly called Evaluation of Onsite Treatment Systems for MOE Staff

This course is an introductory level course that will familiarize participants will the basic concepts of on-site wastewater treatment systems, including what they are, how they function and the basic design parameters. The course also covers assessment & evaluation of existing on-site treatment systems and introduces troubleshooting and remediation methods for failing systems. Approved advanced treatment technologies will also be introduced. A course manual will be provided. It would be helpful for participants to bring their own copy of the “Code and Guide for Sewage 2006” available from Publications Ontario (publication number 510044).


This course is intended for participants new to the on-site sewage industry. A keen interest is always an asset!

Advanced Design Concepts for On-Site Wastewater Treatment Systems

This course builds on the principles and practices covered in “Introduction to On-site Wastewater Systems” (previously called Evaluation of Onsite Treatment Systems for MOE Staff) to help the participant understand more advanced on-site wastewater treatment concepts such as the expected performance level of both conventional and alternative treatment systems, nutrient removal capabilities of on-site systems and impact assessments on water resources. A course manual will be provided.

Course participants should be familiar with the different classes of systems approved for use in Ontario, how they function and their basic design requirements. Participants should also have a good understanding of wastewater system design parameters with respect to water quality and quantity, and a working knowledge of how soil absorption systems perform.

For participants new to this industry, the Introductory level course addresses all of these concepts.
