1. Free chlorine (residueal) requirement: 0.3 mg/L, and end user at 0.05 mg/L (this is the Code of 1998-08-20). I see nobody mentioned that to yet.
2. To get that you have to know the CT value, which is part of your clearwell calculation. But you have to run some lab test to find out the curve of Free chlorine vs. chlorine addition (also called breaking-point)
3. Your pump station design to meet pressure requirement at the end user, especially the fire flow is the big driving forces. To do that, you have to create a hydraulic calculation. Normally, I just creat a hydraulic modeling from the intake to the end user using WaterCAD. I also did not see anyone mentioned this to you.
