Optimization methods are extensively required and applied to solve problems from almost all disciplines, whether engineering, sciences, or economics. The distribution network is an essential part of all urban water supply systems that require efficient design and operation, which may be achieved through the effective application of optimization methods. This article provides a brief overview of the most approached method, models, and numerical examples for multi-objective optimization of water

The main deterministic and heuristic optimization techniques are synthesized and presented, a single-and multi-objective optimization problem is generally formulated, and the main optimization objectives, decision variables, and constraints for the design, rehabilitation, and operation of WDNs are discussed. Additionally, some deterministic and heuristic multi-objective optimization models for WDN design/rehabilitation is included and numerically exemplified. Finally, the advantages and disadvantages of the optimization techniques and models used for designing WDNs are presented along with some recommendations on future research directions in this domain.
