ADEQ's Operator Certification Program establishes guidelines to ensure that only certified operators make decisions about process control or system integrity that affects public health. The program establishes minimum standards for certification and recertification of the operators of community and non-transient non-community public water systems.

Operator certifications are classified into one of four grades by facility type, size, complexity and population served. The grade corresponds with the level of system complexity, with Grade 1 being the most simple and Grade 4 being the most complex. Operators are required to maintain their certification through participation in continuing professional education workshops and must be re-certified every three years.
