Do you need a Sewage Disposal Service license?

Oregon law requires that you must have a license if intending to work on a subsurface sewage disposal system, also known as a septic system, and before you advertise or represent yourself in the business of providing sewage disposal services. The license is a Sewage Disposal Service or SDS license. 

Sewage Disposal Services Include:

  • Constructing any kind of septic systems, or any part of it. This includes grading, excavating and earthmoving work connected with these activities.
  • Pumping, transporting and disposing of contents from any kind of septic system, including graywater tanks or systems and non-water-carried sewage disposal facilities such as portable toilets.
  • Advertising or offering to perform any of the services mentioned above.
