Septic System Permits

On-site septic system permits are processed through Clallam County Environmental Health Services (CCEH). Through the permitting process, the On-site Program works to ensure that septic systems are located, designed and installed correctly following Clallam County Code.

These efforts reduce the risk of contaminating groundwater and surface water, reduce the risk to people from exposure to untreated sewage, and help extend the working life of septic systems.

On-site Septic System Permits, Inspections & Education

What does Clallam County’s On-site Program do?

We protect public health and the environment by making sure septic systems function properly! The On-site Program assures that septic systems are designed, installed, and maintained in ways that meet State and local standards.

It is called the On-site Program because septic systems generally treat and dispose of sewage on the site where it is created.

A household septic system properly designed, installed, and maintained on suitable soil is as effective as a sophisticated sewage treatment plant.

Summary of Septic System Inspection Requirements

Some answers to frequently asked questions about Septic System Inspections can be found on this Inspection FAQ (PDF).

If you own a septic system anywhere in Washington State, you are required by state law to check your septic system on a regular basis to make sure it is working properly. How often you need to check your septic system depends on the type of system you have:

• Basic septic systems with a tank and a gravity-fed drainfield must be inspected at least once every three years. These systems are called conventional gravity septic systems.
• Other types of septic systems must be inspected at least once a year. Pressurized septic systems, sand filters, and mounds are in this category. These types of systems have pumps and other mechanical or electrical parts, and they need to be inspected more often than gravity systems.
• All food service establishments such as restaurants must have annual septic system inspections.

Inspecting and maintaining your septic system is your responsibility. You can hire a professional Septic System Maintenance Provider or Septic System Designer to inspect your system for you, or you can do it yourself with proper training (Septics 201) and if you meet local requirements.

Did you know that if you have a home on-site septic system you are now required to have it inspected every one to three years, depending on what type of system you have?

Wow, really? Not to worry, people in Clallam County can now rest assured they have help at their fingertips. Knowing the inspection requirement would concern many residents, the county set out to develop a plan to help.

They piloted a “Do It Yourself” (DIY) inspection training program in 2011.
