Clallam County, Washington
Septic Systems (On-site Program)
Clallam County's On-site Program protects public health and the environment by making sure that 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.
