Essential and Marginal Duties

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


Water Treatment Plant Operator III

Exercises limited functional direction over WTPO I/II levels during the assigned shift.




Water Treatment Plant Operator I: This is the entry-level classification in the WTPO 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.


Water Treatment Plant Operator II: This is the first experienced-level classification in the WTPO 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 WTPO III in that the latter performs the full range of water plant operations and maintenance duties at a greater level of independence not expected of this class level and is assigned as the designated Shift Operator.


Water Treatment Plant Operator III: This is the full journey-level classification in the WTPO 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. This class is distinguished from the Senior WTPO in that the latter provides technical and functional direction to lower-level staff and is responsible for coordinating work performed by the unit.


Positions in the WTPO 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.
