The water loss rate according to the Minister of Public Works and Housing Republic Indonesia No. 27/PRT/M/2016 at maximum limit is 20%, but PERUMDA Delta Tirta in Taman Subistrict service zone 27.48, Waru Subdistrict I 32.28% II District 20.52%. purpose this study was evaluate level zone. evaluation method for Tawangsari IPA distribution network using Epanet 2.0 software simulation with pressur...

This work proposes a modeling framework to quantify the effects of deliberate organic contamination events on water distribution systems. A bacterial regrowth model and first parallel chlorine decay were combined describe biochemical species kinetics during contaminant injection consisting (TOC) loads. Several attacks modeled using EPANET-MSX. The impact each attack was quantified vulnerability...

Post Administrative Dom Aleixo is a part of Dili City which acts as the central government with an area 33.12 km2, total population in 2015 many 130,095 inhabitants. The purpose this study to discharge capacity spring’s water still sufficient distribute for 10 years future. evaluate clean distribution system according Timor-Leste Strategic Development Plan 2011-2030, method used by using Epanet...

In recent years, pressure-driven analyses of water distribution systems using pressure-flow relationships (PFRs) were shown to be more computationally efficient than those based on flow-pressure (FPRs), such as the widely used Wagner equation and various spline approximations. Using a PFR enhances convergence properties Newton–Raphson method by most network (WDN) solvers. This paper derives new...

This paper proposes a methodology based on genetic algorithms (GA) to calibrate the parameters of chlorine decay model in water distribution system (WDS). The proposed first contemplates that GA is implemented using historical measurements concentration at some sensed nodes unknown values corresponding both bulk and wall reaction coefficients. Once are estimated, optimal-fit used predict each n...

PERUMDA Air Minum Tirta Khatulistiwa distributes clean water in Pontianak Barat District. Services are divided into several zones, one of which is zone H includes Pal Lima Village and Sungai Beliung Village. only 63.82% the population served with a pumping capacity 100 liters/second, based on this data, service not optimal. Population growth results lack at peak hours, so it necessary to analyz...

Gravity flow water distribution systems (WDSs) are used to permit from an input point of highest elevation (source) the terminal points a system (consumers). In such WDSs, typically, there is no need for external power maintain due typical high gradients that exist. However, those cause velocity and pressure some network areas could potentially lead pipes bursting. Currently, only means regulat...
