How to Become a Licensed Operator and Advance within the Operator Profession

Levels of Water Operator Licenses

Water systems are defined through a process of grading points, Class I to IV in both treatment and distribution categories according to complexity and population served. See Appendix A of the Rules. Operators of these systems must show competency by successfully completing examinations in both treatment and distribution categories and possess the appropriate experience. Very Small Water Systems (VSWS) operators are another classification that covers both treatment and distribution characteristics of systems with less than a population of 500.

Characteristics of a Water Operator

An operator must possess the knowledge, skills, ability and judgment to assure safe drinking water. This is measured through a review of education, experience and examination.

Education & Experience

Operators must have a high school diploma or GED. Experience is based on work in a public water system as well as credit for related professions. The Board offers Operator – In - Training (OIT) license status for persons that have successfully passed examinations but have not achieved the required experience. Holding an OIT license shows employers or prospective employers your capability and interest in the profession.

Examinations

Examinations are standardized exams produced by ABC, Association of Boards of Certification. These exams are nationally based, multiple choice, validated and reviewed. The Board welcomes operators to become subject matter experts and participate in the exam development process.

Exams may be taken in the traditional paper-based process or the recently accepted computer-based process. Exams may be taken in the sequential process (pass lower levels and work one’s way up) or may be taken in a direct process (take one exam at the level one wishes licensure).
