1.0 Introduction

1.1 Background

The United States Department of Homeland Security (DHS) has established 18 sectors of

infrastructure and resource areas that comprise a network of critical physical, cyber, and human

assets. One of these sectors is the Water Sector. The Water Sector Research and Development

Working Group has stated that water utilities would benefit from a clearer and more consistent

understanding of their system flow dynamics. Understanding flow dynamics is important to

interpreting water quality measurements and to inform basic operational decision making of the

water utility. Such capabilities are critical for utilities to be able to identify when a possible attack

has occurred as well as knowing how to respond in the event of such an attack. This research

sought to better understand the impact of water distribution system flow dynamics in addressing

such issues. In particular, the project: (1) evaluated the efficacy and resiliency of the real-time

hydraulic/water quality model using stored SCADA data in order to understand the potential

accuracy of such models, and understand the relationship between observed water quality changes

and network flow dynamics, and (2) developed a toolkit for use by water utilities to select the

appropriate level of operational tools in support of their operational needs.

1.2 Operational Decision Support System

The Water Distribution System Operational Decision Support System (WDSODSS) has been

developed to assist water utilities in designing a monitoring/control system for their water

distribution system that will provide water distribution system data (WDSD) for use in support of

various system operations. Such data could include both general operational data as determined

from either real time telemetry or off-line computer models, or on-line data (including data from

both hydraulic and water quality sensors). Operational applications could include 1) energy

management, 2) water quality management, 3) emergency response management, and 4) event

detection.

The operational support data, information, an tools that have been developed as part of this project

have been arranged in an operational hierarchy that can be visualized in a ladder of components,

in which each rung on the ladder will be dependent upon the previous rung. The three basic

components or rungs included in the operational decision support system are illustrated below.

These include 1) Hardware: Supervisory Control and Data Acquisition System (SCADA), 2)

Software: Graphical representation and analysis 3) Hardware/Software Integration: Analytics and

Modeling.

Figure 1. Components of the Operational Decision Support System

1.3 Decision Support System Architecture

The decision support system has been developed to allow the user to access the different

operational components through two different methods: 1) an explicit decisional response path

based on predetermined decisional decision trees (e.g, flowcharts) or 2) an implicit evolving

decisional response path as developed an expert system inference engine in response to sequential

answers as provided through the user interface (see Figure 1). The explicit response path is

supported through a customized website: www.uky.edu/WaterSecurity. The implicit response path

is supported through a stand-alone toolkit that can either be run on the web or on a Android cell

phone. The toolkit uses expert system technology to guide the user through the associated

content. The overall structure of the decision support system is summarized in Figure 2.

2.0 Decision Support System Evaluation Workshops

In order to validate the utility of the WDSODSS, a day-long workshop was held on August 20th,

2014 at the University of Kentucky. The workshop was attended by 16 people representing eight

different water utilities. A summary of the water utilities who participated is provided in Table 1.

3.0 Decision Support System Evaluation Workshop Assessment

During the course of the workshop, the workshop participants were asked to respond to a series of

questions about their utility as well as the content of the workshop. Input was obtained anonymously

using electronic transmitters purchased from Turning Point. In collecting the data, participants were

asked to select from a set of possible responses which were shown on a screen via an embedded

PowerPoint presentation. The compiled results were then shown to the group in real time. A summary

of the various questions and the associated participant response are provided in Figures 3.1 to 3.32.

A summary of the results of the survey are provided as follows:

1) Water quality was identified as the greatest operational challenge.

2) At least 70% of the respondents indicated they would likely utilize the online resources developed as

part of this research.

3) The majority of the respondents indicated they were interested in participating in either a utility

partner program or sponsoring a summer intern at their utility.

4) The cost to replace existing telemetry or SCADA systems was identified anywhere from $25,000 to

greater than $1,000,000.

5) The majority of surveyed utilities utilize radio as their primary communication network.

6) Of those system that do have a SCADA system, 90% maintain a historical database. Of those that

do, all indicated they use the data to evaluate their operational strategies.

7) At least 40% of the utilities have water quality sensors in their distribution system, and an additional

40% considering installing them.

8) 30% of the respondents indicated they did not have a computer model for their water distribution

system.

9) KYPIPE was indicated as the vendor most used for those systems that have a computer model.

10) The majority of utilities that have a model use it for planning scenarios.

11) Most utilities maintain data about their system in a GIS database.

12) 100% of the respondents saw a potential use of the Graphical Flow Model for predicting flows and

pressures in their systems.

13) Over 50% of the respondents envision using the Graphical Flow Model for managing a pipe break.

General Suggestions

• Use Bourdon Gage with 1 psi increments

• Use pressure snubbers

• Make visual survey of test area

• Consider safety issues

• Use cell phones

Run Model and Check Results

• Steady State Analysis

– Check fire flow results

– Pressure (5-10%) of relative pressure gradient

• Extended Period Analyses

– Check tank level predictions

– Trajectories (S residuals < 5%)

• Water Quality Analyses

– Check travel times

– Travel times (< 5-10%)

Steady State Marco Level Calibration

• If observed and predict results are significantly different (> 20%) examine:

– data collection errors

– closed or partially closed valves

– inaccurate pumps or PRVs

– incorrect pipe dimensions

– incorrect network geometry

– incorrect pressure zone boundaries

Sensitivity Analysis • Test various model parameters to assess

impact on calibration data:

– pipe roughness

– pumps

– tanks

– demands

• Efforts should be focused on those parameters

that have greatest impact

Run Model and Check Results

• Steady State Analysis

– Adjust pipe roughness, pump heads

• Extended Period Analyses

– Adjust demands, pump curves

• Water Quality Analyses

– Check for partially closed valves, effective pipe

diameters

Water Quality Analysis

Water Quality Analysis

• KYPIPE provides a powerful interface to the EPANET program to perform water quality simulations on an existing hydraulic model.

• Through this EPANET interface it is possible to:

– Calculate chemical concentrations (e.g. chlorine)

– Calculate water age (residence time)

– Trace a chemical from a source

– Determine appropriate locations for water quality sensors

Calculating Chemical Concentrations *WQ Simulations are performed over an extended period of time, therefore ensure your system is set up for an EPS prior to the WQ analysis

1) Click the tab “Other Data”

2) Click the tab “Quality”

3) Select which quality parameter you would like to calculate

4) Fill in the required parameter tables
