Subject: Example FM SWMM 5 model with and without Surcharge Depth You need to use the surcharge depth for a Force Main in SWMM 5 to allow the engine to find the right point on the pump curve and pump up the rising main. If you do not use a surcharge depth then the flow MAY be very small in the rising main due to a small head difference. Of course the flow in the force main depends on the pump...
