CityWater Project Details
The Project Details contains a number of tabs which display data from the project files.
On the left side of the page are a few buttons.
- New Scenario – This button is only available for administrative accounts. It allows creating new scenarios for an existing project. After a project has scenarios generated, a drop-down menu listing all the scenarios becomes available. Selected a scenario changes the rest of the Project Details page to reflect data from the selected scenario.
- Run – This button is only available for administrative accounts. This button becomes active when a change has been made for the selected scenario. The Run button then must be used in order for the Project Details page to reflect the changes.
- Edit – This button brings up the Edit Project page which is similar to the Create New Project page having the same options. This allows changing the project name, details, and other information that was entered when the project was created.
- Delete – This button removes the project.
The Summary tab in the Project Details page displays information about the project.
- Name - The name of the project.
- Description - A description of the project.
- Created By - The username of the person who created the project.
- Date Created - The date on which the project was created.
- Storage - How much storage space the project files use.
- Flow Units
- Headloss Formula

- Report Start Time
- Number of Junctions
- Number of Reservoirs
- Number of Tanks
- Total Nodes
- Number of Pipes
- Number of Pumps

The Changes tab only appears for scenarios. Select a scenario to access this tab. The tab displays a list of differences between the base model and the scenario. Changes are organized in to changes to the global options, time options, nodes, or links. Changes to nodes and links will contain a hyperlink to jump to the that particular link or node in the project map.
The following sections will be visible:
- Changed Global Options - A list of changes made to the Global Options
- Changed Nodes - A list of nodes that have changed and what the changes were
- Changed Time Options - A list of changes made to the Time Options
- Changed Links - A list of links that have changed and what the changes were
The Model Options tab allows viewing and changing parameters for a the model run. For the base model, the options can only be viewed. For simulations, the options can be changed by clicking the Edit button.
Options are listed alphabetically and include the following:
- Check Frequency
- Damp Limit
- Default Demand Pattern
- Demand Multiplier
- Emitter Exponent
- Max Check
- Quality Chemical Units
- Quality Method
- Quality Trace Node
- Specific Gravity
- Unbalanced Method
- Unbalanced N
- Hydraulic Timestep
- Pattern Start
- Pattern Timestep
- Quality Timestep
- Report Start
- Report Timestep
- Rule Timestep
- Start Clocktime
The Map tab displays information about the project map.
Spatial Reference System
This section displays the spatial reference system the project is using.
- Go To Map – This button will open the project map page.
This section will show any notes or annotations added to the map.
- Nodes – Will show a list of annotations attached to nodes on the project map page.
- Links – Will show a list of annotations attached to links on the project map page.
Clicking on the node or link name will take you to the project map page with the node or link selected. The text of the annotation will be shown along with when the annotation was last modified and who modified it.
A search function is located next to each option to facilitate finding annotations for nodes and links. Enter the node or link name to view annotations for that element.
This section shows a scaled down image of the pipe network in the project Map page.
The Curves tab displays a curve graph for the selected pump. Select the pump curve to display from the drop down menu in upper left portion of the tab. Clicking the icon in the upper right portion of the tab will bring up a menu with commands for printing the graph or downloading the graph as an image file.
The Patterns tab will display a bar graph of water usage. The type of usage can be selected from the drop down list in the upper left portion of the tab. Clicking the icon in the upper right portion of the tab will bring up a menu with commands for printing the graph or downloading the graph as an image file.
The Rules/Controls tab allows viewing, creating, and editing rules and controls applied to scenarios. With the base project, the rules and controls are only displayed and cannot be created or edited. After a scenario has been created, new rules or controls can be added by clicking the add button. Existing rules or controls for a scenario can be edited by clicking the edit button.
Creating or Editing Rules
Rules are used with scenarios to give specific exceptions to how the model runs. Rules use if-then statements to determine how to alter the model run. When creating a new rule or editing an existing rule, the following window appears:
In the If section, you can select any feature that is part of the simulation. You can then specify the conditions that feature needs to reach to trigger the rule. The (And/Or) drop-down menu allows adding additional If statements.
In the in Then section, you can specify a pipe, pump, valve, or link that is changed by the met If condition. This is is often changing the status of the feature. Multiple features can be used.
The Else drop-down allows triggering changes to a pipe, pump, valve, or link when the If condition is no met.
The Priority drop-down permits assigning an order value to the rule—a rule assigned a priority of 1 will trigger before a rule with a priority of 2 and so on.
Creating or Editing Controls
Controls allows changing he status of a link to Open or Close when a condition has been met at a node. When creating a new control or editing an existing control, the following window appears:
The Link section allows selecting a link and designating if the link is to open or close when a node reaches a certain value. The status change can be set to happen using an If or At statement.
The Node section allows selecting a node and designating the value which will trigger the Link status to change. The event trigger can be set to be Above or Below the entered value.
The Energy tab in the Project Details page contains a report of energy usage for each pump in the CityWater project.
- Demand Charge
- Total Cost
- Pump Label
- % Utilization
- Avg Efficiency
- Avg kw
- Peak kw
The Run Summary tab displays a file with a more complete analysis of the pipe network.
The Export tab provides options of exporting the project data as a shapefile.
Report Map Shapefile
- Time Step
- Export Report Map
