N2  - The study deals with capacity expansion of water distribution  networks. a network can be optimized for an increase in capacity in future by two methods. First, it can be designed d tor a time  period and for next the time period it is expanded for the  required capacity. Secondly, it can be designed tor both the  time periods in cons ideation at present and expanded at the  beginning of next time period . In this study both these methods  are compared in terms of total cost and assumed design criteria .  Linear programming, an operational technique, is used in  formulation of these two methods. The objective function is cost an minimization whereas hydraulic and pressure conditions to be met  act as constraints in the models. Simulation with three networks  representing various practical conditions is done. According to  the results obtained , the second method comes out to be cheaper  than the first. The difference in costs tor d net work in  optimization with two methods depends on layouts, topography,  local conditions, and assumed design criteria
