To perform highly complex and difficult duties requiring independent judgement in the installation, maintenance, repair, and replacement of wastewater collection, water distribution, and treatment pond systems related facilities; and to exercise technical and functional supervision over maintenance and technical personnel.


This is the advanced journey level class in the Electrical Instrument and Control Technician series.  Positions at this level are distinguished from other classes within the series by the level of responsibility assumed, complexity of duties assigned, independence of action taken, by the amount of time spent performing lead or specialized duties and by the nature of the public contact made.  Employees perform the most difficult and responsible types of duties assigned to classes within this series including performance of complex and difficult work in electrical maintenance, repair, motors, and pump maintenance and exercise technical and functional supervision over maintenance and technical personnel. Employees at this level are required to be fully trained in all procedures related to assigned area of responsibility.

Classes in the Electrical Instrument and Control Technician series are distinguished from those in the Utility Services Worker series in that the former is required to obtain a higher level of technical, mechanical, and electrical training and experience in order to independently perform the full scope of job duties related to servicing the County’s lift stations which include variable frequency drives per state and local requirements. In contrast, the Utility Service Worker series performs more general maintenance of wastewater, water treatment, and related facilities.
