What is On-Site Sewage?
An on-site sewage system (OSS) is commonly referred to as a septic system or septic tank. OSS is used when a house is not connected to the city sewer system. Many houses in Asotin County use OSS. The major benefit of OSS is that you are able to comfortably live where the city sewer system does not go.
The homeowner is responsible for the installation, maintenance and repairs of their system. Failed systems can result in sewage reentering the home or leaking into the environment. Local and state code provides guidance to ensure a safe, effective and long lasting system. You can read more about the Washington Administrative Code (WAC) that relate to OSS to learn about the responsibilities of the homeowner.

Caring for your OSS
Routine maintenance and minor repairs are necessary to ensure the system will last a long time. OSS systems that are properly built and maintained can last for decades. System failures are more likely to happen in tanks that were poorly designed or lack regular maintenance. Systems also do eventually need to be replaced as they do not last forever.
OSS tanks should be pumped every 3-5 years. You may need to have your tank pumped more often if your tank is undersized for the usage or if your tank is older.
System owners may not be aware that their tank is starting to fail. Regular pumping of the tank helps ensure the system is still functioning as it should. System failures can pose a risk to the environment and health.
