Septics 101 Classes

Thank you for your interest in the Clallam County 'Septics 101' class! It's an enjoyable and helpful class about how septic systems work, and continues to be popular, so classes fill quickly. Please stay tuned to this website for updated information about all class availability.

Remember: Septics 101 is not the training for inspecting your septic system, it is just an informational pre-requisite. There is no test or certificate of completion offered for the Septics 101 class so we request, for their own safety that homeowners wishing to continue with the Septics 201 certification program use the honor system and watch the Septics 101 video first. Those Septics 201 'Do-It-Yourself' Homeowner Training classes are mainly offered online.

Please be aware that even though the law requiring regular septic system inspections is already in effect, Clallam County Environmental Health believes there must be adequate notification and educational programs in place for this program to succeed. We will continue to work on providing training to homeowners and will give ample notice about when active enforcement of the inspection requirements will occur.  Areas of water quality concerns near shorelines and locations where no original septic permit is found on file are beginning to see some septic inspection compliance (SIC) enforcement.

Septics 101 Videos Online through the Department of Health Website
Updated Septics 101 OSS education videos and resource materials are also available on the DOH OSS Homeowner Education webpage. Septics 101 education is a prerequisite for the Septics 201 DIY 'Do-It-Yourself' Homeowner inspection training program. In-person Septics 101 classes will continue to be offered in the future but will be limited by available staff and funding.
