Wastewater Treatment Plant Operator I /II/III
Receives direct (Wastewater Treatment Plant Operator(WWTPO) I) I and general (WWTPO II/III) supervision from assigned supervisory or management staff. Exercises no direct supervision over staff.

CLASS CHARACTERISTICS

Wastewater Treatment Plant Operator I:This is the entry-level classification in the WWTPO series. Initially under close supervision, incumbents with basic experience learn City systems, operations, practices, and procedures. As experience is gained, assignments become more varied and are performed with greater independence. Assignments may vary with the skill and training of the incumbent. Positions at this level usually perform most of the duties required of the positions at the II-level, but are not expected to function at the same skill level and usually exercise less independent discretion and judgment in matters related to work procedures and methods.

Wastewater Treatment Plant Operator II:This is the first experienced-level classification in the WWTPO series. Positions at this level are distinguished from the I-level by the performance of a broader range of duties as assigned, working with greater independence, and exercising greater judgment and initiative. Work is usually supervised while in progress and fits an established structure or pattern. This class is distinguished from WWTPO III in that the latter performs the full range of wastewater plant operations and maintenance duties at a greater level of independence not expected of this class level and may be assigned as the designated Shift Operator.

Wastewater Treatment Plant Operator III:This is the full journey-level classification in the WWTPO series. Positions at this level are distinguished from the II-level by the performance of the full range of duties as assigned, working independently, exercising judgment and initiative, and designation as the Shift Operator. Positions 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. Work is normally reviewed upon completion and for overall results.

Positions in the WWTPO series are flexibly staffed and positions at the II- and III-levels are normally filled by advancement from the I- and II-levels after gaining the knowledge, skill, and experience which meet the qualifications for and after demonstrating the ability to perform the work of the higher-level class.EXAMPLES OF TYPICAL JOB FUNCTIONS (Illustrative Only)
