Chlorine pump

I have been asked to design a chlorine pump that will inject chlorine into a transmission main that delivers water from borehole field with a combined discharge of 750M3 per hour.

The connections of the fifteen borehole sources to the transmission main of 450mm diameter was done 187M and the pint of injection is at 191 M.

The horizontal distance from the borehole fields to the point of injection is approximately 1.5Km . The horizontal distance from the chlorination unit to the transmission main is 205 mm.  Is it possible for me to be referred to references that I can follow up on this? I have one week to deliver this project.

Thank you!
