MURRAY, R. AND W. E. Hart. Review of Sensor Placement Strategies for Contamination Warning Systems in Drinking Water Distribution Systems . JOURNAL OF WATER RESOURCES PLANNING AND MANAGEMENT. American Society of Civil Engineers (ASCE), Reston, VA, 136(6):611-619, (2010).

Impact/Purpose:

Contamination warning systems (CWSs) are a promising approach to mitigate contamination risks in water distribution systems. A critical aspect of the design of a CWS is the strategic placement of on-line sensors that can rapidly detect contaminants. This paper reviews the wide variety of sensor placement strategies that have been recently proposed. This review largely focuses on optimization methods for sensor placement, since the majority of published sensor placement techniques use optimization. Key challenges for effectively using sensor placement optimization in real-world systems are also highlighted: addressing scalability issues, addressing data uncertainties, and modeling sensor failures. Furthermore, this paper summarizes efforts to ensure that these tools can be used by a decision-maker to gain insight into the CWS design process.
