Abstract
This study presents a method for optimizing the design of a water distribution network using pipe diameter as a decision variable under the required demand loading and hydraulic conditions. Data was collected from field studies and an optimization model was formulated from the obtained information using pipe diameter as decision variable. Hydraulic conditions were simulated with EPANET 2.0 software while the optimization model was solved using LINGO 13.0 software. The result of the study revealed that an increase in minimum pressure will lead to reduction in the required pipe diameter. Also the predominant pipe sizes in the optimum solution of the model were 100 mm and 150 mm. However, at higher values of minimum pressure, pipes of larger diameters were not required to obtain the optimal solution to the water distribution system. The optimization model developed will be very useful for determination of economical pipe sizes in a water supply system for newly planned layout and for evaluating existing distribution system for upgrading and strengthening
