Rules for Routing in InfoSewer and InfoSewer SA

• Loading Manholes can take unlimited flow
• Gravity Mains will take all of the flow from the Loading Manholes, but
• d/D will be 1 and q/Q or q over Qfull will be much greater than 1
• A Wet Well can be full if the flow into the Wet Well is greater than the Pump Flow, this can simulate loss of capacity
• A pump flow is based on the pump capacity, pump control rules and the pump curve
• A Junction chamber downstream of a pump will increase in head to pass the flow from the pump
• The force mains downstream from the pumps will have the pump flow based on the needed head at the Chamber nodes.
• So what is real in InfoSewer SA?

· The pump flows

· The head at the Force Mains

· The loading at the Manholes

· The volume and flow lost at the Wet Wells
