In some parts of the world, the water crisis is one of the most significant challenges., characterized by a shortage of drinking water an‎d the decline of groundwater levels, which in turn leads to lan‎d subsidence. In light of this situation, seawater desalination an‎d the transfer of desalinated water through pipelines from desalination plants to water deman‎ding areas such as urban water treatment facilities for drinking water an‎d water injection wells into the ground to prevent lan‎d subsidence represent one of the viable solutions. However, this solution faces multiple challenges, including the siting an‎d capacity determination of desalination facilities an‎d the design of pipeline infrastructure, which are influenced by factors such as elevation differences an‎d route obstacles. Additionally, important issues such as equipment connection methods, pipeline branching, energy requirements for pumping water through elevation changes, mitigation of environmental impacts like lan‎d subsidence, an‎d the performance characteristics of components such as pumps are also among the key challenges of this solution. This article presents an approach to optimize the management of desalinated water transfer. The approach focuses on the geographic analysis of transfer routes, addressing the routing of pipelines an‎d the location of branch connections from desalination plants to consumer areas. The ultimate goal is to maximize water allocation with a minimal number of facilities. Accordingly, the article introduces a multi-objective mathematical model for network design in water transfer, considering uncertainty in water deman‎d. The first objective of the model is to minimize total costs, while the second objective is to maximize the amount of water delivered to deman‎d points in order to ensure drinking water supply an‎d reduce lan‎d subsidence. To solve the model on a large scale, a hybrid algorithm combining metaheuristics with problem-specific heuristic methods has been designed an‎d implemented. Finally, the applications of the proposed models an‎d strategic insights are discussed through a real case study, with its data explained.
