Search the List
Oregon Drinking Water Services (DWS) provides a public list of OHA-certified Backflow Assembly Testers. The list is voluntary so not all certified testers choose to be on the list. Select the county you want, and then you can sort by certification #, name of tester, employer, city, and state. If you are a certified specialist trying to verify a test report, but don't see the tester on the list, email the program at email@example.com
Only OHA Certified Testers are allowed to provide testing services in Oregon. Backflow Assembly Testers who provide their testing services for a fee, are required to be licensed through the Construction Contractors Board (CCB) or the Landscape Contractors Board (LCB). Testers on the following list have provided information that they, or the company they work for, has either a CCB or LCB license; however, this information has not been verified. You can look up CCB licenses or LCB licenses.

If you (the tester) meet the two requirements, send an email to firstname.lastname@example.org with your name, tester certification #, LCB or CCB #, and which county you want to be listed in.
