The Water Health and Economic Analysis Tool (WHEAT): Quick Reference Guide
Installing WHEAT 3.1
Installing from a download
•	Download the WHEAT file into a folder on your computer.
•	Double click on the file WHEAT3.exe to start the setup wizard. Follow the prompts and click
"Next" to move to the next screen in the wizard.
•	The second screen will prompt you to install WHEAT in a default location (in most cases, the
default will be your C drive). It is recommended that you use the default locations for the
program installation.
•	Continue through the wizard and click "Install/'
•	During installation, a WHEAT icon will be placed on your desktop and a new program file listing
will be created, WHEAT / WHEAT 3.1.
•	After the installation, the wizard will alert you to install the MS compatibility pack if your
version of MS Excel is prior to 2007. The compatibility pack must be installed prior to viewing
output reports, but does not need to be installed immediately after WHEAT installation. The
compatibility pack is available from Microsoft at
•	Click "Finish"' to complete the installation process.

Opening WHEAT 3.1
• Double click on the program icon located on your desktop or go to Start / Programs / WHEAT /
WHEAT 3.1 and click on the program name.
WHEAT Home Screen
The home screen provides a
brief description of the purpose
of WHEAT and enables you to
access process. Begin your
WHEAT analysis by clicking
"Analysis." You can also access
WHEAT resources and the help
function by clicking the buttons
at the bottom of the screen.
A Quick Tour
WHEAT Overview
WHEAT assists drinking water and wastewater utility (water sector) owners and operators in quantifying
the utility-level costs, public health impacts and local economic impacts of an adverse event in the water
sector. WHEAT guides users through a consequence analysis by asking simple questions about a user-
defined scenario.
To begin your analysis, select your utility type (drinking water or wastewater) and select a type of
scenario for analysis (loss of assets, hazardous gas release or contamination event [drinking water only]).
You will then provide inputs to characterize your system and establish your baseline. Then you will
answer questions provided by WTHEAT to specify details of the scenario selected. WHEAT then generates
order of magnitude estimates of impacts to the utility, represented by public health (injuries and fatalities)
and economic (utility-level and regional) consequences. WHEAT then produces a report summarizing the
baseline, scenario and consequence analysis results.

HI til Analysis Tool
WHEAT provides water and wastewater utility systems with a step-by-step process for
estimating the economic and public health consequences of an adverse event WHEAT
assesses risks resulting from man-made and natural disaster "what-if scenarios, and
provides an analysis of likely consequences. Utilities can then take necessary actions or
countermeasures to improve emergency preparedness, enhance resilience, and justify
funding for future infrastructure improvements.
To begin a new analysis or load a previous analysis,
select the "Analysis" tab.

System and Scenario Selection
The choice of system type and scenario type should be based on an assessment of how your chosen scenario is expected to
impact your utility. If you are a combined water and wastewater utility, select the system type associated with the system assets
expected to be impacted by the scenario.
i; Ś Drinking Water	Ž Wastewater
Select the "Loss of Operating Assets* scenario to analyze the consequences of one or more system assets becoming
non-operational. Select the "Hazardous Gas Release" scenario option if you expect the chosen scenario to result in the release
of gases stored at your facility (this scenario option also allows for the loss of system assets). Select'Contamination" to view
order of magnitude estimates of drinking water contamination impacts, which water systems can use for risk management
planning when site specific modeling is not feasible.

After you begin your analysis, the screens in WHEAT (the System and Scenario Selection screen is
shown above) are made up of three areas:
Content Area
The middle of the screen contains the majority of the program working area. In the content area,
you will be making selections and inputting data relevant to your analysis.
Navigation Area
The bottom right of the window contains buttons to navigate to the next step, previous step or to
cancel the analysis. Buttons for Home, Help and Resources can be found to the left of these
navigation buttons.
Resources Menu
The left-hand bar labeled WHEAT Resources will open a menu where you can view three
resources: a User's Guide, Technical Documentation and a Case Study. Descriptions of these
resources can be found in the "Resources" section below. These documents can provide further
assistance about the use and methodologies behind WHEAT calculations.

button icon (j^rjj ) on the bottom left of the screen. Descriptions of these resources are below.
•	The User's Guide outlines the steps involved in stepping through a WHEAT analysis and provides
additional detail on various concepts used throughout the tool.
•	The Technical Documentation provide users with a thorough explanation of how WHEAT works and
the methodology behind each function within the tool, including how user inputs are inserted into
•	The Zenith City Case Study provide users with guidance on how to translate the concept of a "what
if' scenario (or hypothetical sequence of events) into quantifiable inputs using case study examples.

File Locations
The following table shows the locations where WHEAT files will be stored. Program files are those files
that are used to run the WHEAT software. Analysis files are the user-generated files that are created by
conducting a consequence analysis. The file locations shown assume a hard disk with the drive letter C,
but can be another drive you choose during installation.
