Distinguishing Features of the Class

An employee in this class is responsible for monitoring and treating the city’s drinking water and water supply in the water treatment plant. Emphasis of the work is on performing routine tests to ensure optimum quality of water and efficient operation of the plant. Work includes conducting hourly rounds of the plant, maintaining records, performing tests on water and plant systems, adding required chemicals to water, troubleshooting mechanical problems, assisting customers, and performing related duties. Work of the water plant operator is differentiated by the level of state certification (C is lowest and A is highest), length of experience and broader knowledge and responsibilities of plant operations, and ability to lead and train other plant personnel. Work is performed under the general supervision of the WTP Superintendent and is evaluated for quality of water produced, accuracy in tests performed, documentation of records, and efficient plant operations.
