Water Distribution Systems Analysis 2010 |
| Abstract: |
In the past, monitoring of operational parameters in the distribution system has been done in a piecemeal and haphazard manner. The distribution system represents the last analytical frontier in the water quality industry. Once the water reaches our aging distribution systems, our knowledge as to its continued integrity is limited by the quality and amount of available data. The development of water security monitoring in the years since 9/11 has the potential to change this paradigm. Since 9/11 numerous communities have installed multi-parameter monitoring stations as early warning systems based on potential water security threats. These continuous on-line systems have recorded large streams of data relevant to water quality in the distribution systems in which they have been deployed. In this study data streams from a number of communities are analyzed for pertinent information as to the health and operation of the distribution system. Changes in water quality are correlated with known causes attributable to day-to-day operational changes and also anomalous events. The data streams show the diversity in what could be termed "normal" operating conditions both within and between different classes and types of systems. This sort of information is critical in understanding and improving the operation of our distribution systems. |
