7:30     Coffee and Registration      Water Security 8:15     Chair’s Opening Address: Water Distribution Infrastructure Protection and Management Paul F. Boulos, Ph.D, President and COO MWH Soft, Inc. Vulnerability assessment, security planning, infrastructure protection, and risk/consequence management today top the list of concerns for every water utility. A revolutionary new computer tool is now available to help water utilities reduce their infrastructure vulnerability and enhance their ability to prepare for and respond to natural disasters and emergencies. The program can be effectively used to identify viable solutions before an incident or disaster occurs, or to assist in responding should it occur. It allows the user to model the propagation and concentration of naturally disseminated, accidentally released, or intentionally introduced contaminants and chemical constituents throughout water distribution systems; assess the effects of water treatment on contaminants; and evaluate the potential impact of unforeseen facility breakdown (e.g., significant structural damage and/or operational disruption). It also enables the user to locate areas affected by contamination; calculate population at risk and report customer notification information; and identify the appropriate valves to close to isolate a contamination event. Finally, it helps the user track contaminants to the originating supply source(s); compute required purging water volume; develop efficient flushing strategies; determine the resulting impact on fire-fighting capabilities; and prepare data for eventual prosecution. 8:45     Assessing Water System Vulnerability Using RAM-W Methodology Ed Wetzel, Ph.D., P.E., Vice President MWH Americas, Inc., CO The events of September 11, 2001 have placed much of our nation's infrastructure under a heightened state of alert. Municipal water systems are particularly vulnerable to physical, biological/chemical and cyber attacks from terrorists. In response to these concerns, Congress has authorized about $80 million in grants to large water systems (serving over 100,000 people) in 2002 to conduct vulnerability assessments and revise risk management plans. Additional grants will be authorized in future sessions to assist smaller systems. The presentation will review the status of regulatory and legislative initiatives supporting this initiative, and describe the protocol (RAM-W) being utilized by water systems to assess their vulnerability to attack. 9:15     Keynote: Securing a Water Distribution System: Agents, Detectors, and Physical Security Rolf A. Deininger, Ph.D, Professor of Environmental Health Sciences & National Expert on Bioterrorism The University of Michigan, MI No distribution system can be made completely secure, but the security can be raised several orders of magnitude to make it next to impossible for a large-scale contamination of a system. The agents of concern are discussed, the detection systems are reviewed, and simple measures to deny access to the distribution systems are shown. 10:00     Water Security – The New World Mark L. Grace, Manager Section Services and Certified RAM-W Trainer American Water Works Association, CO This presentation will cover security developments in the water industry, primarily post September 11, 2001. Legislative and regulatory developments, the security infrastructure that is developing, and other developments on the horizon will be discussed. 10:30     Networking Break      Practical Applications of Hydraulic Modeling: Case Studies 10:45     Modeling Key Trunk Mains in Wales and Scotland – Developing Business Benefits Christopher M. Bros, Principal Engineer, Network Modeling Specialist MWH Europe, England This presentation describes the use of H2ONET on two important Trunk Main Modeling projects for drinking water supply utilities in Scotland and Wales. The model was effectively used to assist design of strategic improvements, rehabilitation works and water securing planning. It is shown that a small investment in network modeling can deliver significant values and benefits to water utilities. 11:15     Developing a Regional Operational Model for Planning, Operations and Design Solutions Polly L. Boissevain, P.E., Senior Project Manager Camp Dresser & McKee, CA The East Bay Municipal Utility District's serves retail water to 11 cities in its West of Hills service area (1.1 milion people). The service area includes 79 pressure zones and has an average daily demand of 130 mgd. Since its initial development, a regional-scale operating model of the service area has been an integral tool for various planning, operational and design evaluations. The presentation will review the initial model development and its many uses, including water quality assessment, during the District’s chloramine startup; outage planning for an outage of the principal treatment plant and supply tunnel serving the area; and design evaluations for new facilities in support of the District’s Seismic Improvement Program to ensure that water supplies will be available following a major earthquake event. 11:45     Modeling the Mouton Niguel Water District Recycled Water Distribution System Ricardo Vivas, P.E., Modeling Manager CGvL Engineers, CA A comprehensive recycled water network model was developed for the Mouton Niguel Water District of Southern California to optimize system operations and generate a powerful predictive tool for peak summer operations to simulate extreme operating conditions. The presentation will summarize the methods and techniques used to construct, calibrate, and optimize a multi-pressure zone model. 12:15     Networking Lunch Break      Advances in Water Quality Modeling and New Regulations 1:30     Keynote: Distribution System Transients Affect Water Quality and Hydraulic Performance Don J. Wood, Ph.D, Professor and Director of Civil Engineering Software Center University of Kentucky, KY Transients in water distribution systems can lead to sub-atmospheric pressures. These systems are particularly vulnerable to pump trips due to power outages. This can result in intrusion of dirty water and pathogens into the distribution system. Several projects supported by the American Water Works Association Research Foundation (AWWARF) and EPP have addressed this issue and the related health risks. A necessary tool for determining risks and evaluating protective measures is a comprehensive transient flow (surge) model. Results form field testing and surge model predictions will be presented and compared. In addition, transient flow models are required to evaluate the hydraulic performance of devices such as pumps, air vacuum valves and regulating valves during transient operations. Examples of these applications will be presented. 2:15     Capital Investment Strategies for Water Quality Improvements to a Distribution System using Advanced Network Modeling Mari Garza, P.E., Senior Professional MWH Americas, TX The use of a dynamic water quality model as a tool to assist water utilities in planning and improving chloramine disinfection strategies is becoming a more widely accepted practice. A detailed infrastructure planning strategy study was carried out for the City of Oklahoma’s distribution system that currently supplies approximately 500,000 retail customers and approximately 350,000 wholesale customers. This required the development and calibration of an 84,000 pipe 24-hour Extended Period Simulation water quality model representing the temporal and spatial distribution of chloramine residuals within the City’s water distribution system. 2:45     Using Hydraulic Modeling to Meet the New IDSE Requirements Daniel J. Askenaizer, PhD, Environmental Legislation and Regulations Expert MWH Global, Inc., CA This presentation will give a general overview of the developing Stage 2 Disinfection Byproduct (DBPR) Regulation (designed to reduce peak DBP levels in the distribution system) with an emphasis on the requirements for water utilities to conduct Initial Distribution System Evaluations (IDSE). IDSE’s are intended to select new compliance monitoring sites that better represent the highest concentrations of TTHM and HAA5. The purpose and particulars of IDSE studies and how hydraulic modeling (water age analysis) can be effectively used to meet those requirements will be discussed. 3:15     Developing and Calibrating a 10,000 Pipe Dynamic Water Quality Model for Cincinnati, Ohio Jonathan P Gray, P.E., Deputy Director of Infrastructure and Planning Black & Veatch Corp., MO This presentation will describe the development, hydraulic calibration, and chlorine calibration work completed for the Cincinnati Water Works, OH. An extensive field sampling program of over forty (40) continuous monitors and over 190 grab sample sites provided the calibration data for summer and winter models. A stringent goal of achieving a calibration accuracy of 0.1 mg/L of chlorine (between model predicted and field observations) at ninety percent (90%) of the sampling sites was met. 3:45     Using Hydraulic Modeling to Optimize Mixing and Circulation in Treatment Plant Clearwells and in Distribution System Tanks and Reservoirs Imad A. Hannoun, Ph.D, P.E., Senior Vice-President Flow Science Inc., VA Clearwells, storage tanks and reservoirs act as reactors in which water ages resulting in diminished water quality. A computer hydraulic model can be used to categorize mixing characteristics and optimize hydraulic performance and efficiencies of these facilities. The model allows flow patterns and mixing regimes to be easily viewed and manipulated as the engineer evaluates existing configurations or explore alternate designs and operational strategies. Modifications can then be rapidly tested at low cost, leading to better designs and operational management practices. Hydraulic modeling will eventually displace most field testing and bench modeling for the evaluation of these facilities. Several actual case studies will be presented, discussed and analyzed.      Advances in Network Model Calibration and Leak Detection 4:15     Keynote: Using Transient Modeling to Improve Water Distribution Model Calibration and Leak Detection Bryan W. Karney, Ph.D, Professor of Civil Engineering University of Toronto, Canada This presentation will discuss the use of advances in transient flow analysis for directly estimating important pipe network parameters such as pipe roughness coefficient, wave speed and leakage location and magnitude. This involves the use of sophisticated inverse transient modeling coupled with genetic algorithm optimization technology. Example applications will be presented and conclusions are stated. 5:00     Creating Calibration Opportunities Through Operational Investigations Victoria K. Underwood, Planning Engineer Las Vegas Valley Water District, NV Daily operational issues and customer complaints provide opportunities for model calibration. A state-of-the-art model calibration needs to evaluate multiple information sources, operational knowledge and water system expertise, yet must be responsive and time efficient when solving everyday operational issues. A case study is provided to demonstrate repeated model calibration efforts using SCADA and field data, while solving a complex problem relating to an actual pressure fluctuation complaint. Included in the study are field investigation plans and problem isolation strategies resulting from network analyses. 5:30     Close of Day One         7:30     Coffee and Networking 8:15     Chair’s Opening Address Paul F. Boulos, Ph.D, President and COO MWH Soft, Inc.      Water Security 8:30     Keynote: Protecting the Nation’s Water System Security: The Potential for Water Quality Modeling Robert M. Clark, Ph.D, P.E., D.E.E., Senior Research Engineering Advisor and Water Protection Task Force Advisor US Environmental Protection Agency As a result of the events of September 11, 2001 the USEPA established the Water Protection Task Force (WPTF) in October 2001. EPA also designated the nation’s water and waste water systems as critical infrastructure and concerns over drinking water vulnerability assessments were immediately identified as being of high priority. The USEPA is now processing grant applications to conduct vulnerability assessments for the nation’s largest water systems. The initial vulnerability assessments have focused on physical security. Another aspect of system vulnerability is the potential for deliberately contaminating a system. If such an event were to occur the need to understand the dynamics of water movement in the network would be critical. A water distribution system computer model can be used to provide this type of information. A model can be used to simulate the movement of an agent from the point where it is introduced through the distribution system. To illustrate the use of modeling for tracking contaminants in a water network a case study describing a Salmonella waterborne outbreak is presented.      Interfacing Network Models with GIS and SCADA – Real Time Modeling 9:15     Integration of Model, Enterprise, SCADA, and Spatial Data for Planning and Operational Support Sri Kamojjala , Civil Engineer Mao Fang, Senior Civil Engineer Las Vegas Valley Water District, NV Integration of model, SCADA, enterprise and spatial data results in powerful tools for routine planning, model calibration, operational support, and emergency response. Integration of model information with various data sources and benefits of such integration are presented. Potential benefits of the integration includes automated model updates, dynamic water demand projections, ease in generation of model scenarios and operational strategies, rapid and reliable operational response, effective decision making, and improved model calibration. 9:45     Using Hydraulic Modeling to Optimize Distribution System Operations and Performance James Thomte, P.E., Senior Project Manager Bohannan Huston Inc., NM Using network modeling in a real-time or responsive, proactive mode offers significant benefits to water utilities – from on-going model calibration to operator training to optimizing pump scheduling and maximizing energy savings. This presentation will discuss the concept, development and implementation of a 44,000 pipe dynamic operational hydraulic model for the City of Albuquerque water distribution system. The model was built directly from ArcInfo GIS with over 287 pumps, 115 pressure regulating valves, 40 tanks and over 1,500 lines of logic controls were used to accurately simulate the dynamic system operations. The model was subsequently used for improving operational system performance and reducing energy costs. 10:15     Networking Break 10:30     Modeling the Houston Water System: from a 300,000-pipe GIS coverage to a fully usable SCADA integrated H2ONET Model David K. Ammerman, P.E., Project Manager Camp Dresser & McKee, FL Using data from a variety of sources, CDM was able to construct a detailed model of the City of Houston Potable Water System. A 300,000-pipe GIS coverage was imported into H2ONET and skeletonized to a 17,000-pipe model. Pumps and tanks were imported from an EPANET model and manually connected to the transmission system. On completion of the model, links to the city’s SCADA system were created to compare the measured and modeled pressures through out the system. The model was used to evaluate improvements thought 2050 and to assist in system operations. 11:00     Integrating Cleveland’s SCADA System for Extended Period Simulations Lindle D. Willnow, P.E., Project Manager Metcalf & Eddy, Inc., MA Metcalf & Eddy is developing an integrated database, GIS and hydraulic model of the Cleveland, Ohio’s distribution system. The model is over 55,000 pipes. Custom reports were written to extract data on 614 of CWD’s 2950 SCADA monitored points and custom MS-Access queries were used to screen and extract only the pertinent data used by the model or GIS. Uses include GIS data population, initial model simulation conditions, operational control statements for extended period simulations with this data, calibrating the model with SCADA data, and developing model runs from an on-demand download of the SCADA data. 11:30     Developing a Rigorous Dynamic Operational Model for the Largest Water Purveyor in Arkansas Julian D. Brown, Environmental Scientist Carter & Burgess Inc., AR Little Rock Municipal Water Works and North Little Rock Water Department were merged together to form Central Arkansas Water, the largest water purveyor in the State of Arkansas, serving 350,000 people. This presentation will highlight how advanced network modeling technology was successfully used to develop and calibrate a rigorous 24-hour Extended Period Simulation model for the combined system. The model comprises over 8,000 pipes and 13 pressure zones and was used to determine the necessary system and operational improvements to ensure reliable operations and optimal performance of the newly combined system. 12:00     Large Scale SCADA Integration for Melbourne Water, Australia Alex McKenzie, Hydraulic Modeling Specialist MWH Australia Melbourne Water (Australia) is the bulk water supplier to a city with more than 3.5 million people. A detailed model of the water supply system has been constructed with very sophisticated PLC emulation control rules due to operational complexity. The water system is continuously monitored by SCADA and more than 450 recorders were used for model calibration. The model has been integrated with the SCADA system to provide real-time comparison between the simulated results and SCADA data. This presentation will describe the methodologies used in the development of the operational model. 12:30     Networking Lunch Break      Innovative Master Planning Technologies 2:00     Keynote: Master Planning in a High Growth Environment Laura Jacobsen, P.E., Planning Manager Nick Braybrooke, P.E., Director of Resources Las Vegas Valley Water District, NV From 1990 to 2000, Las Vegas was by far the fastest growing metropolitan area in the United States. With this tremendous growth rate, the need for rapid and flexible planning and design of new water transmission and distribution facilities has become critically important for the Las Vegas Valley Water District (LVVWD). Facility planning must accommodate new development while ensuring that the level of service to existing customers is not diminished. In addition, the LVVWD must avoid overbuilding facilities, and it must ensure that the cost of growth is not borne by the development community. To accomplish these goals, the LVVWD relies on computer modeling and an approach to master planning that integrates current operations with short and long range development projections to bring new facilities on line “just in time”. 2:30     Denver Water’s Hydraulic Modeling Program – Short and Long Range Steps Edward J. Koval, P.E., Project Engineer Black & Veatch Corp., CO Denver Water serves a population of about 957,000 persons within the Denver metropolitan area. This presentation discusses how Denver Water’s modeling program assists in meeting the area’s short and long range needs. A hydraulic model of the transmission system (comprising 42 reservoirs, 140 pumps and 320 control valves) was initially developed and used to prepare a Treated Water Study. Tasks included: 2005 through 2045 demand projections; hydraulic and water quality modeling; vulnerability/emergency analyses; and Capital Improvements Program. Denver Water has recently initiated a long-term planning program to address complex, long-range distribution system issues. Tasks include: development of an “All Pipes” hydraulic model; determination of water age to determine water quality monitoring sites; energy/operations evaluation; localized hydraulic and water quality modeling; and development of efficient model maintenance procedures. 3:00     Design of Model Scenarios to Effectively Manage Fast Growing Developments and Master Planned Communities John Chan, P.E., Civil Engineer Las Vegas Valley Water District, NV An expert design of model scenarios is vital to the effectiveness of managing fast-growing developments and large-scale master planned communities in Las Vegas. Two cases are presented to demonstrate the real challenges, critical scenarios to address hydraulic requirements, the interim and long-term solutions to both local developments and system expansion, and sizing of water facilities in a regional perspective. A discussion is included on the importance of model update, model integration with a corporate database for project schedules, future demand projections, and identification of oversized pipelines and master-planned communities.      A Revolution in Network Modeling 3:30     Keynote: The Remarkable Evolution of Water Distribution Network Modeling: The Past, Present, and Future A.
