In view of the crucial roll played by plant operators in the effective operation of costly wastewater treatment plants and the extent of the need for new and retrained personnel, it is proposed that a program of operator training for North Carolina be developed. The study examines the skill and training requirements for four grades of wastewater treatment plant operators recognized under the North Carolina certification law. A detailed list of skills is developed from which a suggested training curricula is proposed. Various methods for training operators are discussed, i.e., short schools, full time training, part time training coordinated with on the job training, correspondence courses, and special subject short courses. Available types of training materials are reviewed and the role of audio-visual materials is discussed. Recommendations are made for the development of an integrated program of operator training in North Carolina.
