Distinguishing Characteristics

Mechanical Technician I – This is the first level classification in the Mechanical Technician series. Mechanical Technician I performs duties related to the water treatment plant and delivery system. Technicians in this class typically have two years of related work experience and perform routine maintenance tasks associated with the installation, maintenance, and repair of treatment plant, pump stations, reservoirs, and distribution system equipment. The Mechanical Technician I class is distinguished from the II level by the performance of less than the full range of duties assigned to the II level. Incumbents work under supervision of the plant manager, while learning more complex job skills and tasks. As the Mechanical Technician I progresses in experience levels, the incumbent will begin to work independently on a wide range of mechanical work.

Mechanical Technician II – This is the journey level class in the Mechanical Technician series and is distinguished from the Mechanical Technician I level by the ability to perform the full range of duties assigned with only occasional instruction or assistance as unusual or unique situations arise. Incumbents will posses the ability to diagnose malfunctions in a variety of mechanical and electrical systems. Incumbents will also have a working knowledge of various computer software applications along with the laws, rules, codes, and regulations relating to mechanical system maintenance. Positions in this class are flexibly staffed and are normally filled by advancement from the Mechanical Technician I level.
