To schedule an exam with a DWS state office in Portland, Pendleton, or Springfield: https://app.smartsheet.com/b/form/d4ea1be6e6544c6c9c490937d0c7c0f8
Once an operator has submitted their request, it will be reviewed by the Op Cert team, and we will then contact the operator with a confirmation and also directions to their selected testing location.
PLEASE NOTE: At the end of the course you will receive a certificate of attendance. For small water system certification, please attach a photocopy of the certificate to the Small Water System Operator Application, complete the application and mail to the address listed on the application form.
The application can be downloaded from a link under “Small Water System “S” Certification:” on the DWS Operator Certification web page: http://public.health.oregon.gov/HealthyEnvironments/DrinkingWater/OperatorCertification/SmallWaterSystems/Pages/index.aspx
A small water system operator certificate expires on July 31 of every third year. A certificate will be renewed upon satisfactory evidence presented to the Oregon Health Authority that the operator has completed 6 hours of Department approved continuing education since the issuance date of the last certificate and submittal of the designated application form. When renewed, the new certificate will be valid for three years from the expiration date of the prior certificate.
