3.1. A waler-supply syslem is being designed to serve a pop- ulation of 200,000 pcoplc, with an average per-capita demand of 600L/d/person and a needed fire flow of 28,000 L/min. If the water supply is to be drawn from a river, what should be the design capacity of the sup- ply pumps and water-treatment plant? For what dura- tion must the fire flow be sustained, and what volume of water must be kept in the service reservoir to accommo- date a fire? What should be the design capacity of the distribution nines?
