I am working on one sewerage network on SewerCAD. Its have 6 zones and 6 pumping station. I prepared model of this network in one single file. So, its consist 6 pumping station with 6 pumps and 12 pressure pipes. Initial, I give 100mm diameter to all pressure pipe & gravity pipe. gravity pipe is designed by its own but presser pipe remain with same diameter. My calculation type is design from Base calculation option. (1) So, its possible to design pumping main in sewerCAD? (2) I also entered data of flow and head loss in pump definition. pumps type is Design point (1 point). But its working on higher flow. So its necessary to calculate headloss manually and feed in pump definition as head for proper design?
