The Operations & Maintenance Department
The Operations and Maintenance (O&M) Department is responsible for operating the Water Authority's aqueduct delivery system; ensuring facility security and emergency preparedness; and maintaining and managing the fleet and various other assets. Specifically, the department controls water deliveries to meet member agency demands; manages dam and reservoir operations; ensures water quality; oversees water treatment plant and power generation operations; maintains all vehicles and heavy equipment; provides electro-mechanical support; implements the Asset Management Program (AMP); complies with all applicable environmental regulations; and develops and manages computerized Supervisory Control and Data Acquisition (SCADA) and system maintenance programs.

The Rotating Equipment Maintenance Division
The Rotating Equipment Maintenance Division is responsible for the preventive, predictive, and corrective maintenance on the Water Authority aqueduct delivery system's pump stations and hydroelectric facilities. Preventive maintenance includes routine, planned, and scheduled work required to keep equipment and facilities in a reliable and standard operating condition and preserve and/or extend their service life. Predictive maintenance includes testing and analysis of equipment parameters as an indicator of required future maintenance. Corrective maintenance is performed to return equipment, infrastructure and facilities to their standard operating condition following a breakdown or failure.

The Ideal Candidate
The ideal candidate will be a skilled journey-level technician with proven hands-on experience working on both electrical and mechanical systems in large-scale waterworks, power generation, or hydroelectric facilities. They will be adept at troubleshooting, repairing, and maintaining complex equipment—such as pumps, motors, generators, valves, and control systems—while following industry safety standards and procedures.

This individual is a self-starter who takes direction well, works effectively both independently and as part of a team, and has the flexibility to respond to emergency situations and 24-hour call-outs when needed. They bring a strong willingness to learn, pursue higher certifications, and stay current with evolving technologies and best practices.

Experience with medium-voltage electrical systems, switchgear maintenance, arc flash safety, vibration analysis, pump/motor alignment, sonic meter testing, and large valve operations is highly desirable. The candidate should also be comfortable interpreting blueprints, schematics, and technical manuals; operating diagnostic tools; and documenting work in a computerized maintenance management system.

The successful candidate must be comfortable using computer software applications such as Microsoft Word, Excel, and databases to search for information and prepare basic records. The ideal candidate communicates clearly and logically, collaborates well with contractors and multiple work teams, and is committed to maintaining safe, reliable, and efficient operations.


The Rotating Equipment Technician I/II plays a key role in keeping the Water Authority’s generating and pumping facilities running safely and efficiently. This position is responsible for testing, installing, maintaining, and repairing a wide range of electrical and mechanical systems, plant control systems, and related equipment. Duties include performing preventive and corrective maintenance on pumps and motors, monitoring and control equipment, protection schemes, metering, and sensors, as well as troubleshooting issues to ensure reliable operations.

Distinguishing Characteristics
The Rotating Equipment Technician I is the entry-level class in the Rotating Equipment Technician series. Initially under direct supervision, incumbents learn and perform a variety of skilled, journey-level duties in the design, construction, installation, testing, calibration, maintenance and repair of electrical and mechanical equipment used in pump stations and hydroelectric plants such as protection schemes, monitoring and control equipment, metering, and sensors; medium and low voltage electrical and electronic circuits, motors, generators and transformers; electrical metering equipment; valve and pump motor controls; and other equipment, devices, systems and machinery used in a generating and pumping plant facilities. Incumbents are expected to work independently, performing journey-level duties in one of the classification's primary duty categories (electrical or mechanical maintenance and repair), and learn and perform the remaining class duty categories under the direction of the supervisor and other technicians.

The Rotating Equipment Technician II is the journey-level class in the Rotating Equipment Technician series. Under general supervision, incumbents perform the full range of assigned duties in all of the primary duty categories. This class differs from the lower-level class in the skill level required and the complexity of assigned projects based on knowledge of the Water Authority's equipment, systems, standards and procedures. This class is distinguished from the Senior Rotating Equipment Technician in that the latter is the advanced journey-level class in the series responsible for performing the more difficult and complex assignments in the section's primary duty categories as well as responsibility for training other section personnel. Assignments vary, encompass a variety of tasks, seldom require detailed instructions, and require sound judgment and initiative.
