Construction of hydraulically balanced water distribution network

Abstract

This paper represents creating and analyzing of an adequate hydraulically balanced Water Distribution Network (WDN) based on Geographical Information System (GIS) and Epanet softwares. First a proper and functional WDN has been built and skeletonized by network analyst methodology in GIS. Then the project scenario has been imported into Epanet with simple text or Epanet's readable format consisted of multiple physical and non-physical WDN's objects and Its characteristics. These all in order to determine, analyze and simulate hydraulic parameters of WDN. Second, we analyzed and determined water flows, water in each pipe, water flows direction as well as pressure heads at each node in the network with other required hydraulics parameters. The advantages of this method are simple math and self-correction. Concisely, the context of this work is to use GIS and Epanet-based methodologies as well as solution of closed-loop network problems. Used continuity and energy conservation methods due to determination of pressure heads at each node, water flows and water flows direction at each pipe in the network. As a result got a satisfied hydraulically balanced and a systematic WDN appropriately as the implications of this paper approaches consequently.
