  1. If you are using the water for the residential and personal use only, then the water consumption for a single person a day can be based on the following standards. Home Uses Daily Water Use Per Person -- Gallons Percent Toilet ----------------------------------- 31 --- 45 Bathing/Personal Hygiene ----------------- 21 --- 30 Laundry/Dishes --------------------------- 14 --- 20 Drinking/Cooking -------------------------- 3 ---- 5 Total ------------------------------------ 70 -- 100 Now, as I am not sure about the pipe line designs and height drop etc. I am giving you the links where you can find out different equations for calculating the discharge rate, velocity of water etc. Hope this helps. http://www.calctool.org/CALC/eng/civil/hazen-williams_g http://www.agf.gov.bc.ca/resmgmt/publist/500Series/590304-5.pdf
