Paper Abstract

Distribution system monitoring has typically included a minimal set of water quality parameters, acquired at low frequency. The parameter set, and frequency of data acquisition are insufficient for the surveillance of typical distribution systems' water quality in the event of agent introduction. An improved methodology is discussed. The method includes a more complete set of water quality parameters acquired at higher frequency, mathematical processing to alarm on deviations from operational baseline, pattern recognition of deviations, statistical analysis of recurring events, and a learning function which allows recurring events to be recognized and categorized as normal operation or unknown. Examples of events from distribution systems are presented and discussed.
