Oregon Drinking Water Systems & Operator Certification

Certification Program

Oregon Drinking Water Services (DWS) administers the certification program for drinking water system operators. All community and non-transient non-community water systems must be under the supervision of a certified operator. Trained and certified operators are necessary to ensure that the systems are managed in a manner that fully protects public health and the environment.

Oregon Health Authority, Drinking Water Services is conducting an operator certification customer satisfaction survey, and we would like to ask you to participate. The survey consists of 10 questions, and should only take a few minutes to complete. All survey responses will be completely anonymous, and the survey will remain open until March 15, 2018.
