This work presents a model for the inclusion of chemical water stability in optimizing the operation of water distribution systems. When desalinated water is mixed with surface water and/or groundwater, the blend can become chemically unstable. Such a state can cause the phenomena of “red water,” an increase in corrosion rates, and a reduction in disinfection efficiency. In this study, a method...

Several indices have been used in the past for the assessment of the performance of water distribution systems. In this paper the performance of water distribution systems is evaluated using the resilience index and the failure index proposed by Todini (2000). The method is demonstrated through the analysis of a real world application, the water distribution system of the town of Sofades in Cen...

Drinking water for human health and well-being is crucial. Accidental and intentional water contamination can pose great danger to consumers. Optimal design of a system that can quickly detect the presence of contamination in a water distribution network is very challenging for technical and operational reasons. However, on the one hand improvement in chemical and biological sensor technology h...

As aging water distribution infrastructures encounter failures with increasing frequency, there is a real need for integrated, on-line decision-support systems based on continuous in-network monitoring of hydraulic and water quality parameters. Such systems will form the basis of a Smart Water Grid, allowing water utilities to improve optimization of system operation, manage leakage control mor...

Real-time modeling of a water distribution system (WDS) is critical step for the control and operation such systems. The nodal demand, as most important time-varying parameter, must be estimated in real time. computational burden demand estimation intensive, leading to inefficiency large-scale networks. Jacobian matrix computation Hessian inversion are main processes that dominate To address th...
