There is a crucial need for an effective model that can maximize the seismic resilience enhancement resulted out of every dollar spent on the seismic rehabilitation of water pipe networks. Hence, this study was carried out with an objective of identifying economical seismic rehabilitation policies, for water pipe networks, using a hybrid metaheuristic optimization model. The hybrid metaheuristic optimization is based on the combination of simulated annealing and genetic algorithm. The solution identified by the hybrid metaheuristic yields water pipe rehabilitation policies that lead to maximal post-earthquake network serviceability under given rehabilitation budget constraints. The proposed model was tested on a city-scale pipe network. The comparison of the results produced by the current model with the results from a latest model in literature validates the effectiveness of the proposed model in identifying economical seismic rehabilitation policies for water pipe networks exposed to significant seismic risks. The proposed optimization model is expected to help many utility managers in significantly enhancing the seismic resilience of water pipe networks that are highly susceptible to severe serviceability loss due to earthquakes.
