Large, regional water systems have been turning to computerized Supervisory Control and Data Acquisition (SCADA) systems for more than a decade as water quality regulations become more complex and demands for water increase. However, with the continued decline in the price of computers and the increase in microprocessor capabilities, now even small utilities are able to take advantage of the benefits a computerized SCADA system can offer. While large water systems realize a savings in labor, energy and chemical expenses with computerized instrumentation and controls, small water utilities often get more benefit from other features. For instance, even a small water system can benefit by delegating repetitive tasks, such as turning equipment on or off or transcribing data to a log sheet, to a computer. The flexibility of using a computer, rather than re-wiring hardware, to change treatment sequences in order to meet new regulations or adjust to seasonal fluctuations in temperature is also a real advantage. Time-saving reporting features to record maintenance, water quality or regulatory information can be programmed to meet specific requirements. This paper illustrates how small water utilities are using computerized SCADA systems to meet their own needs within their own budgets.
