The management of the water supply system becomes crucial day by because limited natural sources and rapidly increasing population all over world. However, distribution systems have various technical problems energy loss in can be counted one these problems. In this study, a designated area Yaka district Konya was examined using Hardy-Cross method and, hydraulic simulation softwares EPANET, Wat...

Chlorine is used as a disinfectant in the water treatment process so that treated delivered safely to consumers. However, chlorine concentration decays when flows from plant supply point, due reaction with natural organic matter and inner surface of pipe. Low may encourage bacteria re-growth, while high can result formation harmful chemical components. Therefore, this study aims simulate comple...

A numerical model of a water distribution network designed for a town with 50,000 inhabitants was implemented in EPANET. The paper presents a methodology for computing the chlorine residual concentration decay in the above urban size water distribution system, over a 3 days period of time. The hydraulic system fits a gravity distribution scheme, consisting of a looped network with a tank, 42 no...

This paper proposes a maximum-entropy based multi-objective genetic algorithm approach for the design optimization of water distribution networks. The novelty is that in contrast to previous research involving statistical entropy the algorithm can handle multiple operating conditions. We used NSGA II and EPANET 2 and wrote a subroutine that calculates the entropy value for any given water distr...

Zona Air Minum Prima (ZAMP) Silaing Bawah Kota Padang Panjang memiliki 2 (dua) pipa jaringan distribusi yaitu DMA 01 dan 02. Untuk menentukan performa maka dilakukan analisis Non Revenue Water (NRW), Infrastructure Leakage Index (ILI) Uji Kinerja Hidrolis dengan Epanet. Pada penelitian ini, didapatkan hasil NRW untuk 02 sebesar 46,51% 54,42 % masing-masing, dimana hasilnya masih diatas PerMen P...

An irrigation system is a hydraulic infrastructure that conveys water from the source to the consumers. The aim of the irrigation network design is to find the optimal pipe diameter for each pipe in the network for a given layout, demand loading conditions, and an operation policy. In this paper, we propose a model that uses Genetic Algorithm as an optimization scheme and link this algorithm wi...

Abstract Water utilities form the core part of any urban infrastructure. A spatial database water distribution system (WDS) for Dehradun city has been created in a geographic information (GIS) environment, while drawing data inputs from diverse sources and supply-demand gap analysis performed. Environmental Protection Agency Network (EPANET, 2.0) used to analyze WDS explore its reliability curr...
