Analysis and Design of Urban Water Distribution Network Using Hardy Cross Method and EPANET

Abstract

Water distribution networks (WDNs) serve many purposes in addition to the provision of water for human consumption, which often accounts for less than 2% of the total volume supplied. The purpose of water distribution system is to supply required water quantity at adequate pressure. Water distribution networks play an important role in modern societies because its proper operation is directly related to the population’s well-being. The analysis and design of hydraulic network of Waghapur Naka medical college (WNMC) in Yavatmal city were carried out which contains dead ends and modelling it in computer software EPANET. The hydraulic network was analysed for residual pressure of 7 m. Design for 12 m residual pressure for WNMC in Yavatmal city is given in this paper. The procedure developed for analysis and design in this paper has been explained and tested using a case study of WNMC in Yavatmal city as hydraulic network. It also compares between analytical solutions by Hardy Cross method using Hazen–Williams equation and analysis results using computer software EPANET. The aim of this paper is to develop a simple procedure for water distribution network analysis and design using Hardy Cross method and EPANET.
