**4. Conclusions**

In this work, an "optimal" solution for the design of WDS for the University of Kashmir has been proposed to replace the existing and worn-out WDS, which has already served its function for more than 60 years. The design not only includes the modelling of hydraulic parameters such as pressure head and flow velocity, but the components are also designed in such a way that the objective functions of maximum efficiency of hydraulic performance and minimum capital cost in terms of pipe diameters and valves are satisfied. The main highlights of the work indicating the optimal hydraulic design include the following:
