Oregon Rules & Regulations for Onsite Treatment Systems & Construction Standards
These rules establish requirements for the construction, alteration, repair, operation, and maintenance of onsite wastewater treatment systems. Their purpose is to restore and maintain the quality of public waters and to protect the public health and general welfare of the people of the State of Oregon.
Sewage Disposal Service Business Licensing
The Oregon Department of Environmental Quality issues licenses for three types of sewage disposal services with a duration not to exceed three years following the date of issuance.
Installer License: an installer license is required for any person to construct or install onsite systems or parts of onsite systems or to perform the grading, excavating, or earth-moving work associated with the construction or installation of onsite systems.
Beginning on March 1, 2006, installer and maintenance provider certification is required to obtain a license. The Oregon Department of Environmental Quality has an inter-agency agreement with Chemeketa Community College to provide a program to train and certify onsite system installers and maintenance providers. Email Chemeketa Community College or call 503.399.5181
To re certify, Installers and Maintenance Providers must submit proof of completion of approved CEUs to Chemeketa with a fee. Chemeketa will issue a new laminated certification card with a new certification number and expiration date. Installer and Maintenance providers who do not receive re certification within three years of their most recent certification are no longer eligible to perform construction, installation, repair or perform maintenance of onsite systems.
