Determine the size of a tank that has to be designed for a water supply serving 250,000 people with an average demand of 600 L/Day/Capita and a fire flow of 37,000L/min. It is required that the tank should be designed for a water storage of (i) volume to supply the peak demand of 1.8 times the average demand. (ii) volume to supply fire flow for at least 9 hours, and (iii) volume to supply emergency storage 600 L/day/capita. (1 L = 0.001m^3)
