Color code pipes to show the Criticality system demand shortfall percentage using the Pipe Renewal Planner tool

  Product(s): WaterGEMS, WaterCAD
  Version(s): 08.11.02.xx and later
  Environment: N\A
  Area: Output and Reporting



When a criticality analysis is computed, the network is divided into criticality segments and a system demand shortfall percentage is calculated for each segment. This article explains how to apply a color coding to the pipes according to the associated system demand shortfall computed by the criticality analysis.


1. Create and run the Criticality analysis.

2. Create and run a Pipe Renewal Planner analysis.

a. Open the Pipe Renewal Planner tool from the Analysis menu.

b. Click the new icon

c. Check the Use column for Criticality aspect only.

d. Set the Criticality aspect's weight to 1.0.

e. Set the scenario to the one used to compute the Criticality analysis.

f. Predefined Options tab > Criticality Score Analysis Options tab:

g. Set the Segment Type. Keep in mind that color coding is applied per pipe. A pipe containing a valve will have a raw score computed as defined here.

h. Click the compute button in the Pipe Renewal Planner dialog. Now the pipe property "Raw Score (Criticality)" should be populated.

3. Create Element Symbology color coding to display the "Raw Score (Criticality)" values.

Note that when a Criticality analysis is computed with the option "Consider Valves" enabled, there is not a one-to-one association between segments and pipes. A pipe may be made up of several segments depending on valving. The user has the ability to control how the segment shortfall is transformed into pipe shortfall. This is explained at the following link.
