Job Descriptions

Wastewater Plant Operator I / Ii


DEFINITION

To perform semi‑skilled work in the operation of all equipment in a wastewater treatment plant on an assigned shift. These classifications are assigned to the Miscellaneous bargaining unit for labor relations purposes and are subject to overtime, standby and call‑back assignments.

DISTINGUISHING CHARACTERISTICS

Wastewater Plant Operator I:

This is the entry class in the wastewater plant operator series. Incumbents initially work under direct supervision and perform the more routine operation work. As a trainee, incumbents are supervised more closely to insure compliance with established operations standards of the department, City and State.

Wastewater Plant Operator II:

Positions in this class are normally filled by advancement from the lower class of Wastewater Plant Operator I, or, when filled from the outside, require prior wastewater treatment plant operation experience. Appointment to the higher class requires that the employee be performing the full range of duties for the class and meet the qualification standards for the class. A Wastewater Plant Operator II works under general supervision and is expected to perform journey level plant operation work. Work in this class is distinguished from that of Wastewater Plant Operator I by the greater complexity of the work, by the greater independence with which an incumbent is expected to operate, and the required possession of a Grade II Wastewater Treatment Plant Operator Certificate issued by the State of California.
