About The Position

The Water Resources Plant Maintenance Specialist III performs advanced journey-level lead work involving the training and mentoring of operations and maintenance staff and the installation, maintenance, and repair of water or water reclamation equipment and facilities. Lead duties include reviewing day-to-day projects, scheduling and assigning work, timekeeping and work coordination, training staff, providing technical field knowledge for projects, and contributing input to written performance appraisals or disciplinary matters. The incumbent provides lead supervision and training to plant operators, maintenance personnel, part-time employees, and other staff as needed. For the Water Reclamation Plant assignment, incumbents may work at the Southeast, Northwest, or Greenfield Water Reclamation Plants. Equipment may include bar screens, compactors, degritters, mixers, blowers, odor control devices, centrifuges, UV equipment, chemical metering pumps, sludge hoppers, conveyor systems, boilers, biogas systems, waste gas flares, and filtration equipment. Although maintenance is the primary responsibility, the incumbent may manage daily plant operations under the supervision of the Water Resources Plant Supervisor when necessary. Operational duties include analyzing trends and data, monitoring equipment, optimizing plant processes, collecting and analyzing process samples, and entering data. This position performs journey-level lead work but does not have full supervisory responsibility for maintenance staff.
