Water Treatment Operator II
Santa Fe Irrigation District
Under general supervision or direction, performs a wide variety of skilled and semi-skilled duties in the operation and maintenance of the District’s water treatment plant, lake management and water conveyance systems, facilities and equipment using the Supervisory Control and Data Acquisition (SCADA) system to monitor, regulate, perform and evaluate water flows and treatment processes; collects water samples and performs laboratory analyses to ensure water quality standards are met; and performs related duties as assigned.
DISTINGUISHING CHARACTERISTICS
Water Treatment Plant Operators perform a range of routine to complex skilled duties involved in operating the District’s water treatment plant, lake management system and water conveyance facilities.
Water Treatment Operator I is the entry-level, operator-in-training class in the class series. While being trained and learning operations of SFID’s treatment plant and related facilities and systems, employees in this classification perform the most routine tasks associated with plant operations as allowable with a Water Treatment Operator Grade 1 certification.
Water Treatment Operator II is the first full working level in the class series. Employees perform a range of duties allowable with a Water Treatment Operator Grade 2 certification. Duties require greater knowledge of treatment processes and equipment operations together with demonstrated proficiency to perform such duties with less direct supervision.
Water Treatment Operator III is the skilled journey-level class in the class series. Work is performed independently with only the most unusual problems being referred to the Chief Water Treatment Operator. Work is typically reviewed by checks of logs, reports and periodic inspections of the plant and facilities. Operator IIIs perform a variety of skilled duties such as inspecting plant and system equipment and performing preventative and corrective maintenance including calibration of treatment plant analyzers and collecting samples and performing laboratory analysis duties.
On a rotational basis, Operator IIIs also serve as the shift operator for an assigned shift, with full responsibility for monitoring and operating the treatment plant and associated facilities on that shift. Work performed employees in this classification require a Water Treatment Operator Grade 3 certification.
Positions in this class series are flexibly staffed and are normally filled by advancement from lower class levels once required certifications are obtained and experience requirements met.
