Distinguishing Characteristics

The use of respiratory equipment (including self-contained breathing apparatus (S.C.B.A.)) may be required for this position. Therefore, the Maintenance Technician Trainee/I/II will be required to be free of facial hair that would interfere with the use of a respirator for annual fit test and any occasion which requires the use of respiratory equipment to comply with the District's respiratory program and Cal/OSHA standards.

Maintenance Technician Trainee

This is the sub-entry level class in the Maintenance Technician series. Positions in this class are distinguished from higher level classes in that they are expected to have virtually no experience or technical knowledge in maintenance technician work. The trainee performs the most routine duties under the immediate supervision of higher level positions.

Maintenance Technician I

This is the entry level class in the Maintenance Technician series. Positions in this class are distinguished from the II level in that they are able to perform a narrower range of tasks and have less experience in the mechanical maintenance of a wastewater treatment plant. I level positions undergo a structured training program in preparation for II level responsibilities.

Maintenance Technician II

This class provides continuation of training in mechanical maintenance progressing to the attainment of full journey level skills. Positions in this class are distinguished from the I level in that they perform a broader range of maintenance tasks and are occasionally expected to work independently or provide technical guidance to others in a maintenance crew. The II level is distinguished from III level positions by the extent of experience in mechanical maintenance work. The III level performs the technically most complex tasks and regularly is expected to lead a maintenance crew.
