The “Supervisory Control and Data Acquisition” system (SCADA) serves four objectives:

  1. Allows the remote adjustment of valves which control the flow of water based on demand.
  2. Collects and enables the retrieval of historical data at COMB Offices or via remote computer. Information includes flows, reservoir elevations, alarms, communication, turbidity, pH, temperature, and valve positions.
  3. Provides phone alerts to COMB Operations staff to enable remote corrective action 24/7.
  4. Increases the efficiency of Operations staff by avoiding onsite corrective action and enhances system reliability.

In FY 2017-18, two Programmable Logic Controllers (PLC) were upgraded to wireless communication devices to ensure reliable and secure access. Critical Programmable Logic Controllers will continue to be upgraded based on evaluation from an engineering consultant. These devices would be phased in over time.
