In this study, GIS-based system analysis has been performed for the aim of monitoring and managing the sewerage lines. The model has been designed for a proper and efficient application, which have several objectives such as integrating data processing, modeling, analyzing and reporting. Spatial data have been collected from different sources and several different data layers and their related tabular data have been used in this study. Possible usage of GIS for analyzing sewerage system has also been described in the study. Old and newly planned wastewater lines of the study area and, stream channel, maps and basins were also added to the system. Population estimation and drainage water flow of the year 2033 have been calculated. Obtained drainage water flow rate and population were added to the system and used as a new attribute for the analysis. Additionally, appropriateness of the methods for flow calculation and population estimation were also examined in this study. Comparing present and future population as well as flow estimation, feasibility of the system for further thirty years was also discussed.
