|Drinking water utilities have recognized the importance of online sensors in minimizing distribution system vulnerability to accidental or intentional contamination. However, online sensors with real-time data acquisition and transmission capability can be expensive, forcing small- and medium-sized water utilities to limit the number of sensors to just one or only a few. Therefore it is critical to minimize detection time with the available sensors. Though TEVA-SPOT (Threat Ensemble Vulnerability Assessment and Sensor Placement Optimization Tool) can provide guidance on the placement of water quality sensors, it requires the use of complex water quality models coupled with sophisticated optimization methods for efficient sensor placement. Many small- and medium-sized water utilities do not have the technical or financial resources required for meaningful use of TEVA-SPOT and are not be able take full advantage of water quality sensor technology, therefore facing a higher contamination risk.
|The Optimal Water Quality Sensor Placement Tool (OWQSPT) is a simplified guidance tool for optimal placement of sensors in small- and medium-sized water distribution networks. After the user sets up a model of the system for an Extended Period Simulation (EPS), the optimal water quality sensor placement analysis can be performed with little or no additional input from water utilities. Running the tool is simple, requiring just three simple key strokes. It returns the optimal sensor placement to minimize average detection time, and highlights the recommended sensor locations in the map area. It also generates a detailed sensor placement report.
|This tool is included in the Professional and Premium Packages and requires the KYnetic interface.
