Oregon Drinking Water Systems & Operator Certification
State law requires owners of public and private drinking water and wastewater systems to have their systems under the responsible control and direction of certified operators. 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 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. DWS classifies water distribution systems and treatment plants according to their complexity or size and establishes minimum certification standards for personnel responsible for operating these systems. Oregon offers two separate types of certification based on the system size:

Certification by reciprocity can be granted for individuals who have a current valid certification in another state or province which has a recognized certification program. The certification is granted where the examination, experience, and education requirements are equivalent to Oregon requirements and is determined on a case by case basis.
