Abstract:

Population forecast is a scientific procedure to work out future population scenario. In order to sustain the region water supply scheme over the period of time and to propose the improvement in existing region water supply scheme consumption and design parameters are depending on population of today and coming 4-5 decades. The design population is estimated considering all the factors governing the future growth and development of the project area in the industrial, commercial, educational, and social and administration spheres. Special factors causing sudden immigration or influx of population should also be considered. In present study Population of four decades from 1971 to 2001 is taken as base and forecasted from the year 2013 to 2043. Increase in population over decades is calculated and mean of increase is worked out the paper we presented the population forecasting is done for 31 villages of Dhrafad regional water supply system, using average of results obtained by Incremental increase method, Arithmetic progressive method and Geometric progression method. The statistics of projected population is the basic criteria for the addition of diameter of pipe and its length. Also the magnitude of total head assigned to reservoir and horse power capacity of pump may be prescribed as design parameter of region water supply scheme.
