On-site Sewage Systems (OSS)
The treatment of wastewater from private dwellings and restaurants is carried out by small on-site sewage systems, also known as aseptic systems, which are widely employed across the state. Small on-site sewage systems (OSS) are those sewage systems that have daily flows of less than 3,500 gallons, as defined in Chapter 246-272A of the Washington Administrative Code. In Washington, there are around 950,000 OSS. The right design, installation, and maintenance of an OSS will allow it to successfully treat residential wastewater for a long period.
As a result, both the public’s health and the environment are put at risk.
It is common for system owners to be unaware that their OSS has ceased to perform correctly, and failed OSS are not noticed.
This website explains the significance of properly functioning on-site sewage systems (OSS), how some areas are more environmentally sensitive to pollution from OSS, and the various roles that state agencies, local health jurisdictions, and homeowners play in the management of small on-site sewage systems.
