Septic 201 DIY Homeowner Inspection Program


The Septics 201 DIY Homeowner Inspection Program is part of the County-approved septic system inspection training and certification program that covers conventional gravity, pressure distribution, sand filter, and mound systems. Other system types such as aerobic treatment units, biofilters, and all systems with proprietary devices are ineligible for DIY inspections and must be evaluated by a professional.  See the Summary of Septic System Inspection Requirements for more details.

The online registration process confirms if the septic system at a location is eligible for DIY inspection. If you live in the Marine Recovery Area (MRA), your septic system must have a current professional inspection on file  before you are able to proceed with Septic 201 DIY certification in Clallam County. After the initial professional inspection, MRA homeowners may qualify to inspect their own septic system if they meet the other criteria. 

This online class consists of a 25 minute long video divided up into 10 short chapters followed by an exam. Homeowners must complete the exam and answer at least 80% of the questions correctly to become certified to inspect their own septic system. Once certified, homeowners may submit their inspection reports directly online. 

Clallam County requires Septics 101 as a prerequisite for the Septics 201 DIY training. We ask homeowners to use the honor system and complete Septics 101 training before registering for Septics 201 for their own safety.
