The objective of this project was to demonstrate an always-on, model-based monitoring technology for potable water-distribution systems. The technology uses near-real-time sensor data to estimate key water-quality parameters and corrosivity indices throughout the network so localized corrosion problems can be detected. Researchers successfully created a computerized model of the Fort Drum, NY, water-distribution system, but an unforeseen project-scheduling conflict with a major upgrade of the installations Supervisory Control and Data Acquisition SCADA system prevented completion of the user interface between the model and sensors. The model was successfully tested offline, however, using archived sensor data. It estimated key water-quality parameters and corrosivity indices throughout the distribution system, but its accuracy was validated at only one location. The results were promising but did not return enough data to validate simulation accuracy or to conclude that real-time operation would be successful. Therefore, the demonstrated system cannot be recommended for implementation. This report documents the modeling technology, creation of the Fort Drum model, the general sensor interface design, offline demonstration of the model, and results of evaluation against the project metrics. Lessons learned are documented and recent advances in similar technology are discussed.
