Development of a Wastewater Network Model Using ArcGIS Based Automated Tool

Abstract

In this study a wastewater network model is developed using ArcGIS based automated tool that integrates with AutoCAD and SewerCAD. The developed model consists of three main phases. The AutoCAD phase where input data like served area, land survey, and network planning are prepared in DWG form. Then, the ArcGIS processes the DWG input data and generates output shapefiles required to build a SewerCAD network in the third phase. The shapefiles include all defined parameters required to start network analysis like pipelines layout, manholes’ locations, elevations, assigned populations and sanitary loads. Also, The model provides an unserved area option which allows the model user to eliminate a specific unsewered zone(s) from the predefined served area. The model helps network designers saving time and minimizing efforts since building wastewater networks in SewerCAD becomes a matter of minutes not hours. The model is applied on a wastewater network of an Egyptian village.
