Subject: How to Simulate Pipe Blockage in InfoSewer
For making one or more of your pumps inactive you just need to use the Facility Manager and make the pumps inactive (the grey lines in Figure 2). The other method of making the gravity mains have a really small diameter will not work as the flow is pushed through anyway and the value of q/Q full is very high. One way to do what you want to do is to use a Flow Split and make the flow in the blocked link very small as a fraction of the incoming flow. You will need to add a new link and out fall to handle the excess flow from the pipe blockage (Figure 1).
