PLANT SYSTEMS TECHNICIAN I
PLANT SYSTEMS TECHNICIAN II
Class specifications are intended to present a descriptive list of the range of duties performed by employees in the class. Specifications are not intended to reflect all duties performed within the job.
Under general supervision (Plant Systems Technician I) or direction (Plant Systems Technician II), performs a variety of skilled and semi-skilled duties involved in the maintenance and repair of the City’s water and/or wastewater treatment plants and allied facilities; performs highly skilled tasks involved in the repair or fabrication of precision machine parts at a water and/or wastewater treatment plants and allied facilities; and participates in the repair and installation of electrical and mechanical equipment.
Plant Systems Technician I: This is the entry-level class in the Plant Systems Technician series. This class is distinguished from the Plant Systems Technician II by the performance of the more routine tasks and duties assigned to positions within the series. Assignments are generally limited in scope, contain fairly routine tasks, and are performed within a procedural framework established by higher-level employees. As experience is acquired, incumbents perform with less immediate supervision and continue to learn the full scope of duties and responsibilities. Advancement to the “II” level is based on demonstrated proficiency in performing the assigned functions, possession of required licenses and certifications, completing the progression criteria established by the Department, and upon review and approval of the department head.
Plant Systems Technician II: This is the full journey-level class in the Plant Systems Technician series. Employees within this class are distinguished from the Plant Systems Technician I by the performance of the full range of duties as assigned including serving as lead worker on small crews as assigned. Employees at this level receive only occasional instruction or assistance as new or unusual situations arise, and are fully aware of the operating procedures and policies of the work unit. Positions in this class are flexibly staffed and are normally filled by progression from the Plant Systems Technician I level when experience and required licenses and certifications are obtained and progression criteria met, or when filled from the outside, require prior directly related experience and possession of required licenses and certifications.
