The main objectives of this paper are, designing and balancing of Water Distribution Network (WDN) based on loops hydraulically balanced method as well as using Geographical Information System (GIS) methodology with the contribution of EPANET. GIS methodology is used to ensure WDN’s integrity and skeletonized a proper and functional WDN by using Network Analyst utilizing the geometric network a...

Typically, computer-based tools built on mathematical models define the time-series behavior of contaminants, in dissolved or colloidal form, within spatial boundaries water distribution systems (WDS). EPANET-MSX has become a standard tool for WDS quality modeling due to its collaboration with EPANET. The critical challenges applying include conceptualizing exchanges among multiple reacting con...

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...

Abstract This work compares several alternative methods of pressure-driven analysis (PDA) implemented within the code base EPANET water distribution system modeling software. The resulting includes a direct method, original and newly modified version inverse method currently used by 2.2, two recently published (the global gradient approach-based PDA active set method). latter four solve problem...
