Regarding water resources, the Egypt governorate facing many sustainable availability challenges. Evaluating indicators can be developed to represent the various water environment aspects related to the governorate's target planning, management, and security. In this respect, the water poverty index is universally utilized, but one of the existing reactions incorporates the overall accuracy related to its involved components, criteria, and indicators weighting approaches. Thus, this research proposes an improved multidimensional method for accurate water poverty index (WPI) estimation to overcome the indices overview limitations. However, three integrated approaches based on a principal component analysis (PCA) framework are introduced to facilitate the assessment and represent the interrelationship between WPI's main linked components and their involved combined indicators. On the basis of the newly developed index, this study evaluates the current water poverty in various Egyptian governorates to determine the relative water poverty challenges between them.
In addition, the study concludes that with this approach, WPI can determine the responsible parameters that cause water poverty and their inverse reflection on water infrastructure and provide detailed information on social fragilities as well.
