Question
Water Supply Engineering
Q2: An old town in an established agricultural area with no prospects for extensive development is located along a river that is used as the source of water supply for the community. The conditions of the river are such that it receives its water from a drainage area of 2.590 km² and its low-water flow is 0.00109 m/s/km. The regulations are that only 10% of the river flow can be used at any time for water supply. Past records reveal that the population increased as follows: 1950 1960 1970 1980 12500 15200 17500 19700 Year 1940 Population 10000 100 1990 2000 22000 24400 A. If you are asked to design a water supply system for this community. 1. What would be the expected population in the year 2040? Using arithmetic growth method, 2. Assuming that you decide to supply the community at an annual average demand of 264 Lpcd. and that the maximunt daily demand is 8 times the annual average and the maximum hourly demand is 1.5 times the daily demand, would you be able to supply this demand directly from the river?
