DEFINITION

Under direct or general supervision, performs inspection, diagnosis, overhauling, and mechanical repair work on motors, pumps, valves, and other equipment at the wastewater treatment plant, force main transmission lines, and pumping stations; and performs other job related duties as required.

CLASS CHARACTERISTICS

Maintenance Mechanic I: This is the entry-level class in the Maintenance Mechanic series. Positions at this level are responsible for assisting in the installation, diagnosis, repair, and maintenance of plant, force main transmission lines, and pump station facilities and equipment. Incumbents are expected to assist in and learn to perform the full range of repair and maintenance work including diagnosis, repair, fabrication, and welding duties on force main transmission lines, pump stations, and treatment plant systems, facilities, equipment. Positions at this level usually perform most of the duties required of the positions at the II-level, but are not expected to function with the same amount of skill level and usually exercise less independent discretion and judgment in matters related to work procedures and methods. Work is usually supervised while in progress and fits an established structure or pattern. Exceptions or changes in procedures are explained in detail as they arise.

Maintenance Mechanic II: This is the journey-level class in the Maintenance Mechanic series providing the full range of repair and maintenance duties on plant and pumping station equipment. Incumbents are expected to perform the full range of repair maintenance work including diagnosis, installation, fabrication, and welding duties on force main transmission lines, pump stations, and treatment plant systems, facilities, equipment. This class is distinguished from the Senior Mechanic in that the latter is responsible for technical and functional supervision of lower-level mechanics and is capable of performing the most complex duties assigned. Positions at this level are further distinguished from the Maintenance Mechanic I level by the performance of the full range of duties as assigned, working independently, applying well developed skills, and exercising judgment and initiative. Assignments are performed with the expectation that incumbents have the ability to choose among alternatives in solving job problems and work productively in the absence of a supervisor. 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 only on completion and for overall results.
