This is engineering and sciences technician work at the trainee level. Employees in this class learn to perform a variety of assignments in support of various engineering, plant operations, surveying and scientific tasks and projects. Employees are required to participate in a structured City-sponsored Water Department educational program in Environmental or Engineering Sciences, developing knowledge, skills and abilities required to promote to full performance level engineering aide, engineering technician, construction projects technician, surveyor, treatment plant operator and laboratory technician classes. Employees perform basic tasks in the assignment under the guidance of a higher level technician, engineer or scientist. Assignments expand in complexity as employee's training progresses. Satisfactory completion of academic programs and achievement of required minimum proficiencies at designated intervals in the program are required in order to progress to the next level in the series. Work is performed under the close supervision of an engineering, scientific or technical superior.ALLOCATING FACTORS: (The following conditions must be met for a position to be allocated to this class.)
