Water Demand Analysis for Selected Rural Regions in Visakhapatnam District

Abstract

To analyse the water demand for rural regions is very important to distribute the public water demand and agricultural water demand. In this contest, rural areas under three reservoir command areas namely Konam, Raiwada and Thandava Reservoir command areas located in Visakhapatnam district are selected. Different methods are used for population forecasting and the results are compared with the available actual population in 2011. Decreasing rate method gives satisfactory results and this method is used to determine the present population in the selected rural regions. Total demand for all three regions is obtained and agricultural demand is about 94 to 96%, domestic water demand is about 2.5 to 3.5 %, water losses is about 1 to 1.5 %, fire and public use demand is around 0.5 %, and industrial and commercial demand is less than 0.5% of the total water demand. Per capita total water demand various from 1415 to 1817 cubic meters for selected regions.
