Abstract

Shambu town has faced a problem of potable water supply, still large number of people did not have access to adequate amount of potable water and frequent water interruption is a common problem.  The objective of this research was to evaluate the existing water pressure map and water demand. To achieve this goal, the following input data were collected, base population, growth rate, and pressure map of the area, water production data, and reservoir data. The pipe network and junction network system was simulated to understand its behavior for different inputs using EPANET 2.0. The results showed that the water pressure were not feasible enough to provide adequate water.  Replacing the appropriate diameters to the distribution as well expanding the distribution network in necessary engagements, the total water demand was projected to be 567648 m3/year or 18 L/s and the total water supply was estimated to be 252288 m3/year or 8 L/s. Only 44% of the population was covered by water supply .Thus, use of ground water, or boreholes with an estimated yield of 8 L/s are to be drilled.

 

Key words: EPANET, water demand, water supply, distribution network.
