A charged system search algorithm (CSS) is applied to the optimal cost design of water distribution networks. This algorithm is inspired by the Coulomb and Gauss’s laws of electrostatics in physics. The CSS utilizes a number of charged particles which influence each other based on their fitness values and their separation distances considering the governing law of Coulomb. The well-known benchm...

Su dağıtım sistemlerindeki su kayıplarının azaltılması su, enerji, arıtma ve zaman tasarrufu açısından oldukça gereklidir. azaltılması, ancak hidrolik model yardımıyla basınç yönetimi yapılarak efektif olarak gerçekleştirilebilir. Sabit çıkışlı düşürücü vanalarla bu işlem yapılmaya çalışıldığında ya kritik noktanın minimum değerinin altına düşmesi, da yönetiminden istenen verimin alınamaması mu...

Prioritization of water mains for renewal requires the simultaneous consideration of their structural integrity and hydraulic performance as well as their contribution to the deterioration of water quality. Generally, the impact of deteriorating pipes on water quality in the distribution network has not been taken into account in the decision-making process. To address this issue, the National ...

One of the key factors affecting leakage in water distribution systems is network pressure management by putting Pressure Reduce Valves (PRV) in the flow path and optimal regulation of these vales in water networks. This study aimed at investigating optimal pressure management problems so as to minimize leakage in water distribution networks. To do so, an approach was proposed for both optimal ...

The purpose of a drinking water distribution system is to deliver drinking water to the consumer, preferably with the same quality as when it left the treatment plant. In this context, the maintenance of good microbiological quality is often referred to as biological stability, and the addition of sufficient chlorine residuals is regarded as one way to achieve this. The full-scale drinking wate...

Real-time in-network distribution system monitoring to improve operational efficiency Water distribution infrastructure worldwide is aging, resulting in increasing failures and underscoring the need for real-time monitoring to avoid interruption of an essential service. In this research an end-to-end integrated hardware and software system was developed for monitoring, analyzing, and modeling l...

The optimization of water distribution networks are complex, multi-modal and discretevariable problems that cannot be easily solved with conventional optimization algorithms. Hence, evolutionary techniques such as genetic algorithms and simulated annealing have been extensively employed during the last decade. This study adopts a Tabu search (TS), which is an evolutionary method based on explic...

Abstract Accurate and rapid leak localization in water distribution networks is extremely important as it prevents further loss of reduces scarcity. A framework for identifying relevant event parameters such the location, leakage area, start time presented this paper. Firstly, proposed data-driven methodology consists acquiring pressure data at nodes network through hydraulic simulations by ran...
