Subject: Pump / Force Main System in InfoSWMM and SWMM 5 The basic system consists of: · Wet Well and its associated physical parameters, · Pump Type · Defined Pump Curve, · Downstream Pressure Node and · Downstream Force Main Figure 1: The Basic System Step 1: Wet Well Data Enter the invert elevation, maximum depth of the Wet Well, the physical shape as either a function or shape table and any evaporation or infiltration. Step 2: Define the Pump Type The pump type is defined by a Pump Curve and the On and Off elevations: The four types of pumps are: · Volume - Flow · Depth – Flow · Head – Flow · Depth - Flow Step 3: Define the Pump Curve in the Operation Tab Step 4: Set a Surcharge or Pressure Depth at the Downstream end of the Pump Any positive Surcharge Depth in the Node will allow the program during the simulation to keep the node under pressure forcing flow through the Force Main.
