PSI Testing Centers will re-open on May 1, 2020, and social distancing protocols will be followed for test takers. To alleviate scheduling issues due to the temporary closure, all currently approved candidates will have two additional months added to their one year exam-eligibility period.
Oregon law requires owners of wastewater systems and drinking water systems (public and private) to have their systems under 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.
The Department of Environmental Quality administers the program for domestic wastewater system operators. The Oregon Health Authority Drinking Water Services administers the certification program for drinking water system operators.
