This article discusses an effort by the Pompano Beach (Florida) Utilities Department to improve disinfectant residual levels by using remote chlorine, pressure sensors and field sampling to analyze the situation. The supervisory control and data acquisition (SCADA) system for each lift station near an identified point was upgraded to send data on water system chlorine residual and pressure. The ability to see trends in disinfectant residual levels allowed utility personnel to better understand the effect of procedural changes or flushing activities that included the following: modifying ground storage tank (GST) operations; optimizing chlorine-to-ammonia ratios; managing excess capacity; flushing effectively; investigating forced-flow flushing; and, proving to staff that long-established habits can be changed only by proving the success of a new method.
