"Homes that are not connected to public sewer systems use onsite sewage systems to treat and dispose of household wastewater (i.e., drainage from sinks, showers, toilets, washing machines, etc.). The majority of homes in Kitsap County use onsite sewage systems to handle household wastewater.

There are two main categories of onsite sewage systems: standard gravity systems and alternative systems. Alternative onsite sewage systems utilize different types of technologies to pre-treat the wastewater for safer and more efficient disposal in the soils surrounding a home. Because of the technology and mechanical processes involved with alternative onsite sewage systems, they require active oversite and regularly scheduled maintenance to work properly.

There are many different types of alternative systems in use, ranging from pressure distribution and sandfilters to aerobic treatment units and drip irrigation. Each type has its own unique maintenance needs.

As of January 1, 2000, local health codes require all owners of alternative onsite sewage systems to contract with a certified maintenance specialist to ensure that the required maintenance is performed as needed. This website will summarize and explain whys, whats, and hows of onsite sewage operation and maintenance."
