Demand allocation pattern is one of the key factors in water distribution networks. Due to population growth and more demand need for water, water resource allocation pattern requires more attention. According to the studies available, unfortunately few studies have been conducted on these issues in the context of Iran. Therefore demand allocation pattern to consumption nodes in water distribution networks seems to be neglected to some extent. Taking this existing gap, this study was an attempt to survey Hydraulic simulation of water allocation to each consumption nodes in WaterGEMS software. In this study WaterGems and ArcGIS are used in order to allocate of demand to the consumption nodes in the Ilam University (IRAN). For this, the shape files of studied area border, elevation points, population density in different locations of the university provided using ArcGIS software. This study was done by utilizing there methods: population density, point load data and area load data. The results are presented via the tables and diagrams. Results showed that the maximum required for water distribution network using population density was obtained as 30.48 liters per second. Also, maximum need for the network using point load data and area load data were calculated as 27.23 liters per second. The water transmission line has the ability to pump approximate 17.61 liter per second while the needed for distribution network is more than this amount of water. As a result, transmission line design is not appropriate..
