Stakeholder Engagement Tabletop exercise Working with local utilities to develop a list of ”what if scenarios" a utility may encounter during the decontamination process Establishing typical decontamination protocol, from both the water quality and distribution perspectives The research team has begun gathering material for the table top exercise (TTX) The UofL research team is attending a workshop “Tabletop Exercise Tool for Water Systems: Emergency Preparedness, Response, and Climate“ - November 9 th, 2010 Peer review Began compiling a list of possible independent technical reviewers for the state-of-the-art decontamination report

Preliminary NDM Needs Assessment Commercially available Water Distribution analysis software (products with major market share) KYPIPE – developed at the University of Kentucky in 1970s - (primary focus on small to medium sized systems – all software is fully supported by original developers and engineering staff) H2ONET – developed by MWHSoft - (primary focus on large systems and supporting engineering services) Water CAD – developed by Haestad Methods - (Bentley Software) EPANET2 – developed by Environmental Protection Agency - (limited technical support) Professional contacts KYPIPE: Dr. Don J. Wood H2ONET: Dr. Paul Boulos Water CAD: Dr. Tom Walski EPANET2: Dr. Lewis Rossman TEVA: Dr. Jim Uber Existing technology 2008 BOSC review panel of the EPA Homeland Security Program
Network Decontamination Model Use readily available network data from the Kentucky Infrastructure Authority website to build network models of selected systems. Provide interface for automation of the process and functionality to allow for the input of other critical data (e.g. valve locations, hydrants, etc.).

What will be the final disposition of the flushed water? Where will the water flow? If the system should be flushed, using what hydrant(s)? What is the associated volume of water that will be isolated? If the system should be flushed, can the “upstream” part of the system be used or does the system need to be isolated and flushing water pumped through a hydrant? If so, which hydrant? If the system needs to be isolated, using what valve(s)?
Export to KYPIPE What additional system components (e.g. pumps, tanks) need to be changed in support of system flushing or isolation? How can water be provided to those denied service due to the isolation? What is the operational impact associated with the rest of the system? What operational steps need to be taken to maintain normal conditions until decontamination is complete? KYPIPE Network Decontamination Model (NDM) Network Decontamination Model (NDM) R
Rules-Based Decision Support Tool Decision Information (facts) Inference engine User’s documents Knowledge base Knowledge Acquisition System Human experts AI data mining AI data mining User Who should be notified? How? When? What are the potential health impacts? Immediate? Short- term? What are the environmental concerns? When should decontamination be implemented? What decontamination strategy should be taken? What post event information needs to be provided to decision makers, utility customers, and the general public?

Sensor Placement Rules Public Health concern engine design Selects pipes with diameters greater or equal to 8 inches Selects where chlorine residual concentration is below 0.2mg/L Takes the sum of the pipes lengths and divide by 2 to create impact zone radius Calculates demand of meters within each impact zone Selects fittings with high impact Centrality engine design Selects fittings with more than 3 connections Takes the sum of the pipes lengths and divide by 2 to create impact zone radius Calculate meters within each impact zone Selects fittings with high impact Accessibility engine design Locates pipes with diameter greater than or equal to 8 inches Locates minor pipes that are attached Calculates reduction fraction (minor pipe flow/major pipe flow) Selects pipes with a high reduction fraction
