Search the Database of Licensed Onsite System Installer and Pumper Businesses

The Oregon DEQ maintains a statewide database of Onsite System Installer and Pumper businesses that have been issued a Sewage Disposal Service Business License.

  • If license verification is needed and you cannot locate a business on the list, please call (541) 686-7905 to verify that an application has been received.

Search Tips

  • You may search by business name, by license number, by city, by county or by a combination of these criteria or both. However, if you are not getting any results, try searching by one at a time
  • If you leave business and location criteria blank and choose "All Counties" you will get a list of all businesses statewide with active or expired licenses depending on the selected status.
  • You may use partial names or numbers in your search. For example, if you enter "mc" in the Business Name text box you will get a list of all businesses whose name begins with "mc".
