Smart water network infrastructures

Abstract This paper presents a solution to convert the conventional water network into a smart water network (SWN). Scenarios are synthesized for water recycling inside buildings with less water consumed, minimizing the overall cost. Multiphysics modelling and simulation are conducted with Hysys and Ansys - Fluent in calculating the water flow quantity, pressure of the water network and velocity of water inside the pipe network. Four scenarios are synthesized and modelled for a selected mall building case study. These scenarios reduce the water consumption in the mall from 100% to 29.4%, with a cost-saving of more than 60%.
