Abstract To have an efficient water distribution network, optimal design alternatives need to be identified and analysed using combined hydraulic modelling optimization. This paper reports on the application of fast-messy genetic algorithm (fmGA) coupled with tool EPANET assess select optimum operational alternative for a pipe network. The sole objective optimization was minimize network costs ...

The residence time of water in residential building systems is a critical factor regarding quality at end use. Published literature has highlighted the importance age these and its relationship with pathogenic bacteria such as Legionella pneumophila. However, tools to measure plumbing are typically repurposed from other applications include limitations that make them inappropriate for some syst...

Penyediaan air bersih merupakan salah satu kebutuhan dasar dan hak sosial ekonomi masyarakat yang harus dipenuhi oleh Pemerintah Daerah maupun Pusat. PDAM Kabupaten Kutai Barat ialah perusahaan daerah menyediakan pelayanan bagi di kabupaten barat dalam aspek kualitas, kuantitas, kontinyuitas. Beberapa Kecamatan Melak belum mendapatkan dari minum (PDAM), selama ini penduduk mengandalkan sumber h...

Abstract This work introduces a new bi-objective optimization model for the design of water distribution network (WDN). Reliability and cost are two contradicting objectives that optimized. The evolutionary technique multi-objective (MO) Jaya, hereafter referred as MO-JAYANET, is developed optimal WDN. EPANET used hydraulic solver in this study. concept constraint violation, dominance, non-domi...

Sustainable water use has become a critical issue for the future of planet in face highly probable climate change. The drinking supply sector made significant progress over last 20 years, although improvements management urban hydraulic infrastructures are still required. proposed system, Integrated Tool Water Supply Systems Management (ITWSM), built on three interconnected modules (QGIS databa...

Abstract. In this research, reliability indicators of water distribution networks were evaluated under pipe failure conditions. The case studies included two benchmark and one real-life network in Iran with more hydraulic constraints. Some important presented, such as resilience index, resilience, modified minimum surplus head index. GANetXL was used to do the one-objective two-objective optimi...

Power generation is becoming an increasing problem in South Africa. Africa produces approximately 90% of its electricity from coal-fired power stations and only 5% hydroelectric pumped storage. Durban has a very steep topography, which results high pressure certain parts the water distribution network (WDN). Leakage costly contributes to large extent non-revenue (NRW) network. Pressure reducing...

In the process of water distribution system modeling, nodal demands have been deemed to be most significant input parameters causing uncertainties. Conventionally, users same type are assigned demand pattern, which does not reflect variability in patterns. Hefei City, a lot remote smart meters were installed recent years, providing real-time consumption data for different user sites. this study...
