Sensor Network Design and Performance in Water Systems Dominated by Multi-Story Buildings

Protecting Water Supply Critical Infrastructure: An Overview

“…For example, could infrastructure information, i.e., using GIS information for a particular water system along with other publically available information, be used to create a hydraulic and water quality model that could be analyzed in TEVA-SPOT to ''approximately'' determine the consequences from an intentional contamination event? Finally, a better understanding and more precise quantification is needed about the influence of post-service connection piping detail for estimating consequences , Janke et al 2009). …”

“…In high-rise buildings, contamination entering the building from the municipal distribution system along with its movement through the high-rise building was found to be most sensitive to the operational practices of the building's water system, i.e., pump operation in filling and draining the building's tanks. Janke et al (2009) and collaborators later applied the high-rise building model to study consequences and sensor monitoring location performance in two real, but artificially modified system models. These papers along with others illustrated the influence of model detail on estimating consequences.…”

Finally, a better understanding and more precise quantification is needed about the influence of post-service connection piping detail for estimating consequences (Grayman et al (2008), Janke et al 2009). …”

“…The regret analysis mode allows the user to determine how well a sensor network design performs when confronted with a threat or objective that is different from that used in its design (Davis et al 2013). There are many practical constraints and costs faced by water utilities that cannot be easily modeled (Murray et al , 2009. Designing a CWS is not a matter of performing a simple optimization analysis (Murray et al , 2009.…”

“…There are many practical constraints and costs faced by water utilities that cannot be easily modeled (Murray et al , 2009. Designing a CWS is not a matter of performing a simple optimization analysis (Murray et al , 2009. Instead, the design process is better described by a multiobjective problem that requires informed decision making, using optimization tools to identify possible sensor network designs that work well under different assumptions and for different objectives (Murray et al , 2009U.S.…”
