An employee in this class performs work of considerable difficulty in assisting the Production Supervisor in planning, organizing and supervising the daily activities of subordinate operations supervisors and operators in performing the technical duties of advanced water treatment.  Working under direction, the employee exercises considerable initiative and independent judgment in acting as System Manager for the Supervisory Control and Data Acquisition (SCADA) computer system, maintaining host computers, doing daily data entry, making system backup tapes, purging old files and auditing system files.  Work is reviewed through conferences, reports submitted, and observation of results obtained.

Creates report formats for automatic reporting of data from SCADA files on pumping, filters, all metered flows of plant use water, washwater, reclaim water, chemical inventory, and turbidity reports; programs and maintains Process Logic Control (PLC) computers for plant operation and automation control loops; installs new systems, both hardware and software, to host SCADA computer and PLC’s; designs and constructs control systems for chemical feed PID loops, calibrates instrumentation and process loops to assure correct response; installs additional new control points to SCADA, pulls wire, makes connections in I/O racks, programs logic in PLC’s to communicate with I/O rack connections.

Creates SCADA screens for process control points, remote telemetry points, calculation of chemical feed points, flow control metering, pumping control, and filtration operation; troubleshoots all SCADA, PLC, and I/O communications problems in operations; installs new instrumentation in plant process train to report back into the SCADA system, i.e. on-line finished water pH meter, on-line finished water turbidity meters, basin and BC pH probes, basin surface scatter turbidimeters and on-line filter turbidimeters; maintains all instrumentation equipment installed including calibration of all turbidity and pH meters; evaluates new proposed instrumentation equipment to be used in the treatment process train; trains operational personnel on SCADA system dynamics and changes to plant process controls.

Plans work assignments and schedules projects for the instrumentation and control technicians within the SCADA group; maintains chemical inventories; orders and schedules chemical deliveries; orders supplies and spare parts for control systems and instruments.

Performs related work as required.
