Water distribution network (WDN) is a highly complex urban infrastructurethat is intended to supply water from source node to consumer nodes. As far asthe components of an infrastructure are concerned, the interconnecting pipesthat transport water from source node to the demand nodes account for the majorfraction of the capital cost. Therefore, when designing WDN, the primaryconcern is on finding the optimal combination of pipe diameters that satisfiesthe hydraulic-head requirements at minimum cost. More recent methodologiesemploy direct heuristic and stochastic heuristic algorithms for the design ofWDN. In this study, the use of Honey-Bee Mating Optimization (HBMO) stochasticalgorithm for the design of WDN in the Gurudeniya Service Zone, Gurudeniya, SriLanka, has been examined. In-built hydraulic constraints have enabled thealgorithm to deliver results without needing a separate hydraulic simulationsoftware in this design. The solutions given by HBMO algorithm and the solutionimplemented by National Water Supply and Drainage Board, Sri Lanka have beencompared. From the implementation of the HBMO algorithm, results show that theHBMO algorithm is successful in addressing the WDN design problem with givenhydraulic constraints for Gurudeniya Service Zone.
