To qualify for a Wastewater Operator Certification Program in Oregon via reciprocity, you must:

• Hold a valid wastewater certification in good standing from another state or Canadian province, or a Professional Operator certification from Water Professionals International.
• Meet Oregon DEQ education and experience requirements. View the requirements.
• Register and apply online through Your DEQ Online and pay the application fee. Use the Wastewater System Operator Certificate application and select YES when asked if it is for reciprocity. You will need to attach a copy of your current certificate. Learn how to do this in Your DEQ Online.

Once your complete application is received, we will verify your out-of-state certification is in good standing and that you took the standardized exam.

NOTE: If you have passed a standardized ABC exam, we can give you a waiver from the exam at the same grade. If you took a state-specific (non-standardized) exam, we can give you a waiver from the exam at one grade lower than the corresponding Oregon grade.

If you have additional questions, please email OpCert@deq.oregon.gov​.​
